It should be noted that, unless otherwise specified, technical terms or scientific terms used in this application shall have the usual meanings understood by those skilled in the art to which this application belongs.

An embodiment of the present application provides a display device for a video frame image. As shown in FIG. 1 , the device specifically includes: a processing unit 11 configured to perform peeling processing on the current frame image to obtain multiple sub-images corresponding to the current frame image And the identity information corresponding to each sub-image; the storage unit 12 is used to store each sub-image in turn in the target cache block corresponding to each sub-image according to the identity information corresponding to each sub-image and the storage rate, and the target cache block has An identity tag used to characterize the reading order of the target cache block; a reading unit 13, which is used to sequentially read the data stored in each target cache block according to the reading sequence corresponding to the multiple target cache blocks and the preset read rate sub-images, and sequentially output and display multiple sub-images.

Below in conjunction with the display device of the video frame image shown in Figure 1, the detailed process of outputting and displaying the video frame image by the display device of the video frame image is specifically described:

Among them, the current frame image is specifically the video frame image that needs to be output and displayed in the video composed of the active_3d image in the current interlaced scanning scene, and for the active_3d image in the current interlaced scanning scene, each complete image is divided into two Each field signal (upper field and lower field), and each field signal is divided into left image and right image (L image and R image), that is, after the current frame image is stripped, four sub-images can be obtained, including the upper field left image, The right image of the upper field, the left image of the lower field, and the right image of the lower field, and the identity information corresponding to each sub-image, and for any sub-image, the identity information corresponding to the sub-image is used to indicate that the image is specifically the left image of the upper field, the upper field Which one of the right picture, the left picture of the next field and the right picture of the next field, therefore, when the sub-image is stored in the memory after stripping, the identity information corresponding to each sub-image needs to be stored together; where the target cache block is the aforementioned Each sub-image corresponding to the current frame image determines the corresponding stored cache block, and when the cache block is set in the memory, an identity tag will be added to each cache block according to the order and specific quantity when multiple cache blocks are set. That is to say, each target cache block has a unique identity tag, and the reading order of multiple target cache blocks can be determined according to the identity tag in each cache block; wherein, the storage rate is the current video frame The rate at which images are written to the memory one by one by WDMA. WDMA is the execution subject that directly writes sub-images into the memory. The storage rate is related to the video source and the frame rate of the video. Video sources include but are not limited to: set-top boxes, U disks, etc. , different video sources determine different frame rates of videos, and different frame rates of videos determine different storage rates. Therefore, the storage rate of video frame images can be determined by the frame rate of videos. For example, due to the active_3d image A video frame image in the formed video needs to be stripped into four sub-images. Therefore, when the corresponding frame rate of the video is 30i, its corresponding storage rate is 120i; when the corresponding frame rate of the video is 60i, its corresponding storage rate The rate is 240i; among them, the reading order is the order in which the target cache block is read by RDMA, and RDMA is the execution subject of reading the sub-image in the memory, and multiple targets can be determined by the identity tag of each target cache block The reading order of the cache block, therefore, after determining the reading order, only need to sequentially read the sub-images stored in the target cache block based on the preset reading rate, so that multiple sub-images can be output and displayed in sequence; Wherein, the preset read rate is determined according to the refresh rate corresponding to the panel of the display device. For example, assuming that the refresh rate corresponding to the panel of the display device is 120HZ, the preset read rate is 120i, and the display device Including but not limited to: TVs, monitors, etc.

In the embodiment of the present application, the specific execution process of the above-mentioned processing unit 11, storage unit 12, and reading unit 13 is: first, the processing unit 11 performs stripping processing on the current frame image to obtain multiple sub-images corresponding to the current frame image and The identity information corresponding to each sub-image, that is, the four sub-images corresponding to the current frame image, such as sub-image A, sub-image B, sub-image C, and sub-image D, and the identity information corresponding to sub-image A is the left image of the upper field, and sub-image B The corresponding identity information is the right image of the upper field, the identity information corresponding to the sub-image C is the left image of the lower field, and the identity information corresponding to the sub-image D is the right image of the lower field. Each sub-image is sequentially stored in the target cache block corresponding to each sub-image, and the target cache block has an identity tag used to represent the reading order of the target cache block, that is, the target cache corresponding to sub-image A is determined according to the identity tag Block 0, sub-image B corresponds to stored target cache block 1, sub-image C corresponds to stored target cache block 2, and sub-image D corresponds to stored target cache block 3, and finally the reading unit 13 caches according to multiple targets The reading order corresponding to the block and the preset reading rate read the sub-images stored in each target cache block in turn, and output and display multiple sub-images in sequence, because the identity tag is used to represent the reading order of the target cache block , therefore, in the target cache block 0, target cache block 1, target cache block 2, and target cache block 3 according to the read order and preset read rate, the sub-image A, sub-image Image B, sub-image C, and sub-image D, and sequentially output and display sub-image A, sub-image B, sub-image C, and sub-image D.

The present application provides a display device for a video frame image. The display device for a video frame image provided by the present application includes: a processing unit, a storage unit, and a reading unit; first, the processing unit performs stripping processing on the current frame image to obtain the current A plurality of sub-images corresponding to the frame image and identity information corresponding to each sub-image; secondly, each sub-image is sequentially stored in the target cache block corresponding to each sub-image by the storage unit according to the identity information corresponding to each sub-image and the storage rate, The target cache block has an identity tag used to represent the reading order of the target cache block; finally, the reading unit reads each target in turn according to the reading order corresponding to multiple target cache blocks and the preset read rate The sub-images stored in the cache block are output and displayed in sequence. Because, in this application, for any target cache block, the target cache block has an identity tag that characterizes the reading order of the target cache block, that is, through the identity tag in each target cache block, the The reading order of multiple target cache blocks can be determined, and the sub-images stored in each target cache block can be sequentially read through the reading order of multiple target cache blocks and the preset reading rate, and make Multiple sub-images can be output and displayed according to the reading order and preset reading rate. Therefore, there is no need to additionally store the identity information corresponding to each sub-image, thereby avoiding excessive occupation of storage resources by the identity information corresponding to the sub-image.

The embodiment of the present application also provides another display device for a video frame image, as shown in FIG. 2 , which is explained below in conjunction with FIG. 2 :

Further, as shown in FIG. 2 , the device further includes: a setting unit 14, used for the processing unit 11 to set a plurality of buffer blocks in the memory before performing stripping processing on the current frame image, wherein the buffer area The number of blocks is 4N, and N is a positive integer; the generation unit 15 is used to generate the identity tag corresponding to each cache block according to the quantity of multiple cache blocks and the corresponding setting sequence of multiple cache blocks; the addition unit 16 uses Each identity tag is correspondingly added to each cache block.

Wherein, since each video frame image will be stripped into four sub-images, therefore, in order to store the four sub-images corresponding to each video frame image respectively, the number of multiple cache blocks needs to be set to a multiple of 4, and For the specific number of multiple cache blocks, it can be set according to user definition, and this embodiment does not specifically limit it, wherein, the setting sequence corresponding to multiple cache blocks is the order in which multiple cache blocks are set in the memory, for example, in Block 0, block 1, block 2...block 7 are set in sequence in the memory, then the setting order of the 8 blocks is (1) block 0, (2) block 1...(8) block 7 ; Wherein, the identity tag is specifically a binary tag, and the first binary code of the binary tag (that is, the lowest bit of the binary code) is used to represent the left image/ The information on the right, the second bit of binary code (that is, the second lowest bit of the binary code) is used to represent the upper/lower field information in the identity information corresponding to the sub-image that should be stored in the target cache block, and the other bits of binary code are used to represent each The location information of a target cache block in multiple cache blocks, and the specific number of bits of the binary tag is determined according to the number and setting order of multiple cache blocks. Exemplarily, when four cache blocks are sequentially set, namely block 0, block 1, block 2 and block 3, the corresponding setting sequence is (1) block 0, (2) block 1...(4) Block 3, according to the generation rules of the binary label, only two binary codes are needed to satisfy the uniqueness of the identity label, that is, block 0 corresponds to 00, block 1 corresponds to 01, block 2 corresponds to 10 and Block 3 corresponds to 11; and when 8 cache blocks are set in sequence, that is, block 0, block 1, block 2, block 3, block 4, block 5, block 6 and block 7, and The corresponding setting sequence is (1) Block 0, (2) Block 1...(8) Block 7. According to the generation rules of binary tags, three binary codes are needed to satisfy the uniqueness of identity tags. Therefore, Block 0 corresponds to 000, Block 1 corresponds to 001, Block 2 corresponds to 010, Block 3 corresponds to 011, Block 4 corresponds to 100, Block 5 corresponds to 101, Block 6 corresponds to 110, and Block 7 corresponds to 111, so that By analogy, a unique binary tag can be set for each cache block. In this case, when the first binary code (ie, the lowest bit of the binary code) and the second bit of binary code (ie, the second lowest bit of the binary code) ) is 01, the aforementioned block 1 and block 5 are consistent, and if the third binary code is 0, it means that the cache block is block 1, and if the third binary code is 1, the cache The block is block 5. It can be seen that the bit width of the binary tag is determined by the number of multiple buffer blocks, and according to the first binary code (ie, the lowest bit of the binary code) and the second bit of the binary code (ie, the second lowest bit of the binary code) of the binary tag It can determine the sub-image corresponding to the identity information stored in each cache block, and then cooperate with the binary code of other bits to determine the location information of the cache block, that is, to determine that the cache block is in multiple cache blocks That is to say, after generating the identity tag corresponding to each cache block according to the number of multiple cache blocks and the corresponding setting order of multiple cache blocks, each identity tag is correspondingly added to each cache area In the block, according to each identity tag, it can be determined what kind of identity information sub-image is stored in the cache block.

In the embodiment of the present application, before the processing unit 11 performs stripping processing on the current frame image, the setting unit 14 first sets a plurality of cache blocks in the memory, and the cache blocks need to be set in the memory in advance, that is, in the memory according to The fixed memory capacity is divided into multiple cache blocks, and then the generation unit 15 generates an identity tag corresponding to each cache block according to the number of multiple cache blocks and the corresponding setting sequence of the multiple cache blocks, that is, generates each cache block Blocks are used to read sequential identity tags, and each identity tag is correspondingly added to each cache block by the adding unit 16, thereby adding an identity tag to each cache block, so that the cache is determined according to each identity tag A sub-image of what identity information is stored in the block.

Further, as shown in FIG. 2 , the storage unit 12 includes: a first determining module 121, configured to determine the storage sequence corresponding to multiple sub-images according to the identity information corresponding to each sub-image; a second determining module 122, configured to The identity information corresponding to the image and the identity tag in each cache block determine the corresponding target cache block of each sub-image; the storage module 123 is used to store each sub-image in sequence according to the storage sequence and storage rate corresponding to the multiple sub-images Each sub-image corresponds to the target cache block.

Wherein, the storage order is the order in which multiple sub-images are stored in multiple target cache blocks. When reading, it is necessary to read the upper field LR first, and then read the lower field LR. Therefore, in order to ensure the reading efficiency, each The identity information corresponding to each sub-image determines the storage order of multiple sub-images, so that the upper field LR is stored first, and the lower field LR is stored later; after determining the storage order of multiple sub-images corresponding to the current image, it is necessary to determine the respective corresponding The cache block, that is, the target cache block, has an identity tag used to represent the reading order in each cache block, so it can be determined according to the identity tag that each sub-image corresponding to the current image should be stored in multiple caches Which cache block in the block, and after determining the target cache block, WDMA stores each sub-image in turn in the target cache block corresponding to each sub-image according to the storage order and storage rate corresponding to the multiple sub-images, that is Sub-images corresponding to the reading sequence can be directly obtained during subsequent RDMA reading.

In the embodiment of the present application, the storage unit 12 is used to sequentially store each sub-image in the corresponding target buffer block of each sub-image according to the identity information corresponding to each sub-image and the storage rate, and the specific storage process is: firstly, the The first determination module 121 determines the storage order corresponding to the multiple sub-images according to the identity information corresponding to each sub-image, that is, the order in which the multiple sub-images are stored in multiple target cache blocks, and then the second determination module 122 based on the corresponding storage order of each sub-image The identity information and the identity tag in each cache block determine the target cache block corresponding to each sub-image, that is, determine the cache blocks corresponding to each sub-image stored in multiple cache blocks, that is, the target cache block Finally, the storage module 123 sequentially stores each sub-image in the target cache block corresponding to each sub-image according to the storage order and storage rate corresponding to the multiple sub-images, so that when the subsequent RDMA reads, directly obtain the data of the corresponding read order sub image.

Further, as shown in FIG. 2, the storage module 123 is specifically used to: detect whether a sub-image corresponding to a history frame image is stored in each target cache block; For the sub-image corresponding to the frame image, store the multiple sub-images corresponding to the current frame image in sequence in the target cache block corresponding to each sub-image according to the storage order and storage rate; if each target cache block has stored historical frames For the sub-image corresponding to the image, it is judged in turn according to the storage order whether the sub-image corresponding to the historical frame image in each target cache block has been read; if the sub-image corresponding to the historical frame image has not been read, then in the historical frame image When the corresponding sub-image is read, overwrite and store the sub-image corresponding to the current frame image into the corresponding target cache block according to the storage order and storage rate; if the sub-image corresponding to the historical frame image has been read, then follow The storage sequence and storage rate overwrite and store the sub-image corresponding to the current frame image into the corresponding target buffer block.

Wherein, the historical frame image is a certain frame image before the current frame image, assuming that the current frame image is the 4th frame, when there are 4 buffer blocks, that is, the target buffer block corresponding to each sub-image corresponding to the current frame image is the same as The target cache block corresponding to each sub-image corresponding to the previous frame image is the same 4 cache blocks. At this time, the historical frame image refers to the previous frame image, that is, the sub-image corresponding to the third frame image; and When there are 8 cache blocks, assuming that the target cache block corresponding to each sub-image corresponding to the current frame image is the last 4 in the preset order, then the historical frame image at this time may refer to the last two frame images, That is, the sub-image corresponding to the second frame image. It should be noted that, in the case where the sub-image corresponding to the historical frame image has been stored in each target cache block, it is necessary to judge each target cache block sequentially according to the storage order Whether the sub-image corresponding to the historical frame image in is read, and then overwrite and store the sub-image corresponding to the current frame image into the corresponding target cache block according to the reading situation, and the specific storage methods include two, the first method It is to store the sub-image corresponding to the current frame image after sequentially detecting that the sub-image corresponding to the historical frame image in the target cache block has been read. The second method is to store the sub-image corresponding to the historical frame image in all target cache blocks. After all the sub-images are read, each sub-image corresponding to the current frame image is correspondingly stored in the target buffer block. However, since the sub-images need to be read in the predetermined order of the upper field LR and the lower field LR, when reading the historical frame When the corresponding lower field LR in the image, its upper field LR will not be read again, that is, the target buffer block corresponding to its upper field LR is in the state of waiting for the sub-image corresponding to the current frame image to be written, and in order to ensure the reading efficiency, obviously The second method is not applicable, therefore, the first method is selected to store the sub-image in this embodiment.

In the embodiment of the present application, the storage module 123 is used to sequentially store each sub-image in the target cache block corresponding to each sub-image according to the storage sequence and storage rate corresponding to the multiple sub-images, and the specific storage process is: first detect Is there any sub-image corresponding to the historical frame image stored in each target cache block? If not, it means that there is no sub-image corresponding to the historical frame image stored in the target cache block. sub-images corresponding to one frame image, then at this time, according to the storage order and storage rate, the multiple sub-images corresponding to the current frame image are sequentially stored in the target cache block corresponding to each sub-image; and if there is, specify the target The sub-image corresponding to the historical frame image has been stored in the cache block, and then judge whether the sub-image in the target cache block has been read according to the storage order, because if there is a historical frame image corresponding to the target cache block If the sub-image is not read, it means that the preset read rate is slower than the storage rate, that is, the rate of WDMA is slower than the rate of RDMA, then the target cache block cannot To store the sub-image corresponding to the current frame image, that is, the sub-image corresponding to the current frame image needs to wait for the sub-image corresponding to the stored historical frame image in the target cache block to be read before overwriting and storing. Therefore, when the historical frame image When the sub-image corresponding to the image has not been read, when the sub-image corresponding to the historical frame image is read, overwrite and store the sub-image corresponding to the current frame image to the corresponding target buffer block according to the storage order and storage rate On the contrary, according to the storage order and storage rate, the sub-image corresponding to the current frame image is covered and stored in the corresponding target buffer block, so that each sub-image corresponding to the current frame image is stored in the corresponding target buffer block, so that Waiting for sub-images stored in subsequent target cache blocks to be read.

and sequentially reading the sub-images stored in each target cache block according to the reading sequence corresponding to the target cache blocks and a preset reading rate, and sequentially outputting and displaying the sub-images.

6. The method of claim 5, wherein prior to performing the stripping process on the current frame image, the method further comprises:

setting a plurality of cache blocks in a memory, wherein the number of the cache blocks is 4N, and N is a positive integer;

generating an identity tag corresponding to each cache block according to the number of the cache blocks and the setting sequence corresponding to the cache blocks;

and correspondingly adding each identity tag to each cache block.

7. The method according to any one of claims 5 to 6, wherein sequentially storing each sub-image into the target cache block corresponding to each sub-image according to the identity information corresponding to each sub-image and the storage rate comprises:

determining a storage sequence corresponding to a plurality of sub-images according to the identity information corresponding to each sub-image;

determining a target cache block corresponding to each sub-image based on the identity information corresponding to each sub-image and the identity tag in each cache block;

and sequentially storing each sub-image into a target cache block corresponding to each sub-image according to the storage sequence and the storage rate corresponding to the plurality of sub-images.

8. The method of claim 7, wherein sequentially storing each of the sub-images into the target cache block corresponding to each of the sub-images according to the storage sequence and the storage rate corresponding to the plurality of sub-images comprises:

detecting whether a subimage corresponding to the historical frame image is stored in each target cache block;

if the sub-images corresponding to the historical frame images are not stored in each target cache block, sequentially storing the sub-images corresponding to the current frame image into the target cache block corresponding to each sub-image according to the storage sequence and the storage rate;

if the sub-images corresponding to the historical frame images are stored in each target cache block, sequentially judging whether the sub-images corresponding to the historical frame images in each target cache block are read or not according to the storage sequence;

if the sub-images corresponding to the historical frame images are obtained, when the sub-images corresponding to the historical frame images are read, storing the sub-images corresponding to the current frame images into the corresponding target cache blocks in a covering manner according to the storage sequence and the storage rate;

and if the sub-images corresponding to the historical frame images are read, storing the sub-images corresponding to the current frame image into the corresponding target cache blocks in a covering manner according to the storage sequence and the storage rate.
