first embodiment

FIG. 2 is a schematic structural diagram of the first embodiment of the VR data input device of the present invention. As shown in Figure 2, the VR data input device of this embodiment includes:

The first compression module, the input end is connected to the PC interface, the output end is connected to the selection module, and is used to receive the first HDMI signal from the PC interface, and the compression processing generates the first compressed HDMI signal and sends it to the selection module;

The second compression module, the input end is connected to the AP interface, the output end is connected to the selection module, and is used to receive the second HDMI signal from the AP interface, and the compression processing generates the second compressed HDMI signal and sends it to the selection module;

A selection module, connected to the first compression module and the second compression module, for receiving the first compressed HDMI signal and the second compressed HDMI signal respectively, and selecting one of the compressed HDMI signals for output;

A conversion module, connected to the selection module, for receiving the compressed HDMI signal output by the selection module, converting the compressed HDMI signal into a MIPI DSI signal and outputting it;

The processing module is connected with the conversion module, and is used for receiving the MIPI DSI signal output by the conversion module, decompressing the MIPI DSI signal and outputting it to the display device.

In this embodiment, the computer and the mobile terminal are used as two HDMI signal input sources, the image data output by the computer is output by the PC (Personal Computer) interface, which is the first HDMI signal, and the image data output by the mobile terminal is output by the AP (Application Processor) interface The output is the second HDMI signal. After the first HDMI signal output by the PC interface is compressed by the first compression module to realize 1/3 display stream compression (VESA Display Stream Compression, DSC), the first compressed HDMI signal is generated and sent to the selection module. After the second HDMI signal output by the AP interface is compressed by the second compression module to achieve 1/3DSC compression, a second compressed HDMI signal is generated and sent to the selection module. After the selection module receives the first compressed HDMI signal and the second compressed HDMI signal, it selects one of the two and selects one of the compressed HDMI signals to send to the conversion module. After the conversion module receives the compressed HDMI signal output by the selection module, it converts the received compressed HDMI signal into a Mobile Industry Processor Interface Display Serial Interface (MIPI DSI) signal and sends it to the processing module. After receiving the MIPI DSI signal, the processing module performs DSC decompression processing on the MIPI DSI signal, and sends the decompressed MIPI DSI signal to a display device such as LCD or OLED for imaging. Usually, the display device of the VR device includes a left-eye display and a right-eye display. After decompression processing by the processing module, the decompressed MIPI DSI signal is also processed into a left-eye image signal and a right-eye image signal, which are sent to the left-eye display and right-eye image signal respectively. eye display, so that the left eye display displays the left eye image, and the right eye display displays the right eye image.

In this embodiment, the first compression module and the second compression module may use SiI8630 chips. The LatticeSiI8630 chip is an MHL/HDMI (Mobile High-DefinitionLink/High Definition Multimedia Interface) transmitter suitable for mobile terminals/personal computers, and an HDMI 2.0 transmitter that can be integrated with the application processors of smartphones, tablets and notebook computers For seamless connection, support HDMI1.4/2.0 and MHL1/2/3 protocols. The SiI8630 chip can have a built-in 1/3DSC IP, which can realize the compression of RGB format data while transmitting, reduce the amount of data, and expand the bandwidth. In addition, in addition to supporting 1/3DSC compression, the SiI8630 chip also supports up-sampling/down-sampling of Chroma, and realizes the conversion of YCbCr 4:4:4 format through chroma down-sampling Compress into YCbCr 4:2:2 format to reduce data volume and expand bandwidth.

YCbCr (also known as YUV) is a color coding method (belonging to the APL system) used in the prior art. It is mainly used to optimize the transmission of color video signals. Compared with the transmission of RGB video signals, its biggest advantage is that it only takes up very little space. bandwidth, while RGB requires three independent video signals to be transmitted simultaneously. In YCbCr, Y stands for Luminance, that is, the grayscale value, Cr and Cb stand for Chrominance or Chroma, which define two aspects of color: hue and saturation, which are represented by Cr and Cb respectively, and Cr It reflects the difference between the red part of the RGB input signal and the brightness value of the RGB signal, and Cb reflects the difference between the blue part of the RGB input signal and the brightness value of the RGB signal, that is, the color difference signal. The YCbCr formats mainly include YCbCr4:4:4, YCbCr 4:2:2 and YCbCr 4:2:0. Among them, the YCbCr 4:4:4 format means that the three elements have the same resolution, and the YCbCr 4:4:4 format completely retains all information values. In the YCbCr 4:2:2 format, the chroma element has the same resolution as the brightness value in the vertical direction, and half of the brightness resolution in the horizontal direction, that is, there are two Cb and Cr for every four brightness values, which are usually used to construct High quality video color signal. The YCbCr4:2:0 format does not mean that there are only Y and Cb but no Cr components. It means that for each scan line, only one chrominance component is stored at a sampling rate of 2:1, and adjacent scan lines Store different chroma components. That is to say, if one line is YCbCr 4:2:0, the next line is YCbCr 4:0:2, and the next line is YCbCr 4:2:0...and so on. For each chroma component, the sampling rate in the horizontal and vertical directions is 2:1, so it can be said that the sampling rate of chroma is 4:1.

In this embodiment, the SiI8630 chip can also be used to compress the format YCbCr 4:4:4 into YCbCr4:2:2 to realize 1/2 compression. That is to say, the SiI8630 chip in this embodiment can perform 1/3DSC compression on HDMI 2.0 signals whose input format is RGB, and can also convert HDMI 2.0 signals whose input format is YcbCr 4:4:4 into YCbCr 4:2:2. It should be noted that 1/3DSC compression and conversion of YcbCr4:4:4 to YCbCr 4:2:2 cannot be used at the same time, because although the SiI8630 chip has two data compression methods, its internal operation is bypass, and 1 The data input format for /3DSC compression is RGB, YcbCr 4:4:4 or YCbCr 4:2:0, and there is no YCbCr 4:2:2 format, so the two compression methods cannot be compressed repeatedly.

In actual implementation, the first compression module and the second compression module of this embodiment may also use SiI8632 chips or SiI9630 chips. The built-in 1/3DSC IP in the SiI8630 chip can also use non-built-in DSC IP. The compression processing of the SiI8632/SiI8632/SiI9630 chip is already known to those skilled in the art, and will not be repeated here.

In this embodiment, the selection module can use the EP9261E chip to select one of the two outputs. The Explore EP9261E chip is a 6GHz HDMI 2.0 signal 2-in 1-out (2-IN 1-OUT) switcher, which is used to select the output path of the AP interface or PC interface. noise. The EP9261E chip has integrated equalizer and jitter removal circuit, supports 2 HDMI input ports with integrated equalizer (2-IN integrated equalizer), supports 1 HDMI output port with jitter removal function (1-OUT debounce circuit) to ensure its good switching characteristics, the signal is intact and undistorted, and long-distance transmission is realized. At the same time, the EP9261E chip is compatible with HDMI1.4 and HDMI 2.0 specifications, supports 2-port on-chip extended display identification data (Extended Display Identification Data, EDID) RAM, supports on-chip passive/active display data channel (Display Data Channel, DDC) switch, to reduce system cost. In addition, the EP9261E chip also integrates an e-Flash MCU to simplify customer development. In actual implementation, by configuring the corresponding software in the registers of the EP9261E chip, the gating function of the output path of the AP interface or PC interface can be realized. The processing flow of the EP9261E chip is a conventional general flow, which has been understood by those skilled in the art, and will not be repeated here.

In this embodiment, the conversion module can use the TC358870 chip to convert the MIPI DSI signal. ToshibaBridge IC-TC358870 is an integrated chip that converts HDMI signal to MIPI DSI signal, input interface HDMI, clock rate 297MHz (Max), video output interface MIPI DSI8Lane, audio output interface I2S, TDM. The conversion of the HDMI signal into the MIPI DSI signal by the TC358870 chip is already known to those skilled in the art, and will not be repeated here.

In this embodiment, the processing module may be a driver IC of the display device, and performs processing such as DSC decompression of data.

This embodiment provides a VR data input device for a VR integrated/separated combination machine. By setting the first compression module and the second compression module, the HDMI signal is received from the PC interface and the AP interface respectively and compressed to form a two-way Compress HDMI signals, select two compressed HDMI signals through the selection module, realize the seamless switching between the two input modes of the PC end and the AP end, realize high-speed MIPI signal sharing in the switching scene of the two input modes, overcome the existing The defect that high-speed MIPI signals cannot be switched directly through topology wiring solves the technical problem that restricts the integration of VR all-in-one machines and VR split machines. In this embodiment, SiI series chips and EP9261E chips are used to switch between two HDMI signals. The combination of the two can provide multiple implementation methods, which can be compatible with built-in DSC IP and non-built-in DSC IP, and can also realize 1/3DSC and YcbCr 1 /2 compression Both compression methods can meet customer requirements to the greatest extent. The system architecture of this embodiment is simple, easy to implement on various types of existing VR devices, and only need to adjust the hardware part, and introduce IC control signals by adding AP general purpose input and output control lines (General Purpose Input/Outpu, GPIO) , does not involve software system modification, and the existing software can be directly imported and used, which can not only ensure the power consumption requirements of the AP, but also shorten the software development cycle. The versatility of the chip used improves the utilization rate of the hardware and the effectiveness of development. Wide application prospects.

With the continuous development of integrated chip manufacturing technology, many APs have built-in DSC IP, which can realize data compression by itself, such as SAMSUNG Exynos 8890 chip. In this embodiment, for an AP with a built-in DSC IP function, the AP automatically performs DSC compression on the data to generate a compressed HDMI signal, which is output to the selection module through the AP interface. Therefore, different from the first embodiment, this embodiment does not need to use the second compression module to implement 1/3DSC compression, and the selection module is directly connected to the AP interface.

In this embodiment, the structure and processing of the first compression module, the selection module, the conversion module and the processing module are the same as those of the first embodiment described above, and this embodiment can also achieve the technical effect of the first embodiment, and will not be repeated here.

third embodiment

FIG. 4 is a schematic structural diagram of a third embodiment of a VR data input device of the present invention. This embodiment is an extension of the scheme of the first embodiment. The main structure is the same as that of the aforementioned first embodiment, including a first compression module, a second compression module, a selection module, a conversion module and a processing module.

The input end of the fourth compression unit is connected to the output end of the third compression unit, and the output end is connected to the selection module, which is used to receive the second pre-compressed HDMI signal from the third compression unit, and perform recompression processing to generate the second compressed HDMI signal for transmission to select the module.

In this embodiment, the first compression unit and the third compression unit may use SiI9630 chips, and the second compression unit and fourth compression unit may use SiI8630/SiI8632/SiI9630 chips. Among them, the SiI9630 chip is a super MHL1.0/HDMI 2.0 transmitter (backward compatible with HDMI 1.4), with its own high-bandwidth digital content protection (High-bandwidth Digital Content Protection HDCP) 2.2 function, capable of receiving and decompressing 8-bit YCbCr 4: 4:4/RGB format, 8/10-bit YCbCr 4:2:0 format DSC 1.1 data, and supports chroma upsampling/downsampling: 8-bit YCbCr4:4:4 to YCbCr4:2:2 and YCbCr 4 :2:2 to YCbCr 4:4:4, and 8/10-bit YCbCr 4:2:0 to YCbCr4:2:2 and YCbCr 4:2:2 to YCbCr 4:2:0. During specific implementation, the SiI9630 chip uses chroma downsampling to realize YCbCr4:4:4 to YCbCr 4:2:0, which can meet the DSC IP input format requirements in SiI8630/SiI8632/SiI9630 and realize secondary compression.

In the aforementioned first embodiment, since the DSC IP input format in the SiI8630/SiI8632/SiI9630 chip is RGB, YcbCr 4:4:4 and YCbCr 4:2:0, there is no YCbCr 4:2:2 format, so DSC and Repeat compression for YCbCr downsampling. In this embodiment, by introducing the SiI9396 chip as the first compression unit and the third compression unit, the YCbCr 4:2:0 format is generated by the SiI9396 chip, and after realizing 1/2 compression, it is sent to the second compression unit and the fourth compression unit. SiI8630/SiI8632/SiI9630 chips perform 1/3DSC compression, so that the compressed data volume is only 1/6 of the original data volume.
