The process of selecting specific overlay content to be used for being inserted into main video frequency program can assign one or more classification identifier to implement through at first giving the label of each available overlay content signal in advance.Then, when the label in the main video streaming sends the signal on insertion opportunity, can from the label the main video frequency program extract classification identifier and with available overlay content signal in each in one or more classification identifier compare.Any overlay content signal with coupling identifier all will contain and be fit to be inserted into the overlay content in the main video frequency program.
Said classification identifier can comprise at least one in following: the subject information of vision signal; The subject information of overlay content; The existing precedence information that inserts window; Insert the characteristic of window; The audio frequency of overlay content surmounts information; The resolution of overlay content; Channel number; Be used to insert the target programm name of overlay content; The regional program level of target program; The transmission identifier of target program; Format descriptor; Comprise text point; Speed; Font size; The text component descriptors of at least one in font type and the font color and comprise video resolution; Video location; To at least one the video component descriptors etc. in the video speed of animation.
Sending under insertion signal on opportunity and the situation of existence, further the optimization selection process more than one suitable overlay content signal.For example, except that assigning one or more classification identifier for each overlay content signal in advance, assign " fit quality " parameter in advance also can for said overlay content signal.That is,, can there be the corresponding matching class parameter of the correlation of instruction content and specific classification to each classification identifier.Then; If existing with the same category identifier is a plurality of overlay content signal of characteristic; And if this identifier and being complementary of being included in defined in the label in the main video streaming, so with selecting to have the overlay content signal of the highest corresponding matching class parameter.The method can be used to the efficient of maximization targeted advertisements when using the part screen video to insert.
In using classification identifier and both instance embodiment of quality of fit parameter; Can label (for example both have been appended to vision signal; At tagging processor 29 places) append to each (for example, at overlay content generator 26 places) in one or more overlay content signal again.Can classification identifier be provided as at least a portion of identifying information.Can assign corresponding quality of fit parameter (for example, at overlay content generator 26 places) to overlay content signal to each classification identifier.Said quality of fit parameter can be indicated the relative correspondence between each overlay content and the classification identifier.In this instance embodiment, video processor 28 can be discerned the overlay content signal that has the same category identifier with vision signal.Then, video processor 28 can from quality of fit parameter with indication and the highest correspondence of classification identifier discern and select overlay content the overlay content signal.
Can be at least one remote location place through the respective video processor 28 of said position the selection and the insertion of overlay contents take place.Another is chosen as, and the selection and the insertion of overlay content can take place through video processor 28 in central position.Then, can with through a plurality of copies of revising video content from central location assignment to one or more remote locations to be used for further distribution.
Can distribute place place label to be appended to overlay content signal in central authorities through overlay content generator 26.This label can confirm that which person in one or more video processors 28 at respective remote location place will insert overlay content in the particular video stream.
Video processor can be inserted in the insertion window of vision signal the counterpart with the substitution video signal with overlay content signal.Another is chosen as, and can overlay content be inserted in the insertion window of vision signal and with it to mix with the counterpart of vision signal.Alpha blended can be used to mix the corresponding insertion window portion of overlay content and vision signal.
Show instance embodiment among Fig. 3 according to video processor 28 of the present invention.The instance embodiment of the video processor 28 shown in Fig. 3 comprises optional memory distributor 30 and the optional video transrater 31 that is used in the insertion that overlay content takes place, realizing to the modification of the data rate of video streaming.Be understood by those skilled in the art that; Insert overlay content and need not the data rate of the modified video streaming of gained is carried out under the situation of any modification at needs, can video processor 28 be embodied as and not have the transfer capability that is provided by optional memory distributor 30 and optional video transrater 31.Another is chosen as, and video transrater 31 can be through structure to keep the raw data rate of vision signal.
In the instance embodiment that needs are changed; Memory allocator 30 can be to the import bag of regulation through the header information scan video signal of the level and the vertical dimension of coded image (for example, from arbitrary vision signal of the video source 21,22,24 of Fig. 2 and/or 25 or from the overlay content signal of the overlay content generator 26 of Fig. 2).Be used to store the memory that each imports one or more images of vision signal into if having, video transrater 31 can need this information so.Except that the optional memory space that is used for individual video signals, rate converter 31 also comprises the memory that is used for the overlay content on the top that is inserted into or covers vision signal.At United States Patent (USP) 7,046, the instance of prior art memory allocator has been described in 677.
To not import that video packets directly sends to video transrater 31 into but at first it will be deposited in the bag dynamic random access memory 33 via dynamic RAM Controller 32.Through label being deposited to the arrival of notifying CPU (CPU) 34 each bag in the reception information module 36 of communicating by letter with CPU 34.Said bag of said tag recognition and CPU 34 keep and make the address of bag in the dynamic random access memory 33 and receive the tabulation that the information of wrapping is complementary corresponding to institute.
Although video transrater 31 can be handled a plurality of video streamings, must at first it be organized into whole frame and the boundary between each frame carries out multiplexed.CPU 34 follows the trail of the order of the bag that comprises each frame and confirms frame is forwarded to from bag dynamic random access memory 33 order of video transrater 31.The bag that CPU 34 indication dynamic RAM Controllers 32 will be selected as expected in proper order is forwarded to video transrater 31 from bag dynamic random access memory 33.
Except that the data rate of regulating each crossfire, video transrater 31 also can be implemented to insert and cover.CPU34 can analyze the identifying information that is contained in the label that deposits in the reception information module 36 and whether have the insertion window that can be used for inserting overlay content with definite particular video stream.In particular video stream after identification insertion opportunity, the identifying information that said CPU is contained in can the label based on overlay content and/or video streaming is selected the specific overlay content that is used to insert, and institute is discussed in detail like preceding text.Then, CPU 34 can instruct dynamic RAM Controller 32 to be provided to rate converter 31 from the suitable bag of bag dynamic random access memory 33.For example, CPU 34 can instruct dynamic RAM Controller 32 will from bag dynamic random access memory 33 corresponding to being provided to rate converter 31 with the bag of the overlay content of particular video stream coupling.Rate converter 31 can use various alpha blended technology to mix the corresponding insertion window portion of overlay content and vision signal.
Be understood by those skilled in the art that in the embodiment that need not change, available suitable processor substitutes memory allocator 30 and video transrater 31 is inserted and covered to carry out.
After video transrater 31 is handled said frame, the bag of gained (for example, through the bag of conversion and/or contain the modified bag of overlay content) order is turned back to bag dynamic random access memory 33 via dynamic RAM Controller 32.Simultaneously, notice CPU 34 each bag transmit.This accomplishes so that CPU 34 knows each position that wraps in the dynamic random access memory 33 again through again label being deposited to receive in the information module 36.In the case, rate converter 31 provides said label to receiving information module 36.If CPU 34 need be about the extraneous information of particular video stream, it can submit to request to comprise the data of any selected bag with reception to dynamic RAM Controller 32 so.
Video streaming or overlay content streams that pre-adjustment has label can currently be used to implement the existing protocol (for example, SCTE-30 and SCTE-35 agreement) that the full screen digital advertisement inserts and accomplish through revising.
If with different resolution transmission main video signals, so available different resolution is sent identical overlay content in different time.For example, " resolution " can be one in the parameter of definite " fit quality ", perhaps, can assign different classification ID to different resolution.
Be that the video that is transmitted by the DPI server during the said time window can be changed on the meaning of " main video " signal, same procedure can be through extending to use with DPI (digital program insertion).Under this type of situation, provide the functional system of splicing (or DPI server itself) can insert label, and classification ID can be used to insert or the coverage goal advertisement content.In this way, the DPI server can utilize ability of the present invention under the situation that needn't revise ad content itself.This gives the flexibility that little head end only covers or inserts on originally by the specific part than the ad content of stub end transmission.
There is characteristic about the subject classification program capable of using of main program.For example, the ATSC system can use the combination by the available parameter of its careless domination, for example mainly reaches the regional rank, transmission ID of minor channel number, programm name, program etc.
Targeted advertisements can be realized through the overlay content that inserts event initiator at special time.If event/segment has many promoters, subject information can all use same category ID to it so, but has different " fit quality " parameters.Certainly, rotate in the overlay content if use to hope to insert in all promoters' institute, so dynamically change " fit quality " parameter at different time.
Overlay content signal can be transferred to video processor 28 via various host-host protocol.If overlay content happens is to be the subwindow of characteristic with the full-motion video, bandwidth and memory requirement can become crucial so.In the case, maybe be easier in the time of more approaching actual insertion time via these data of MPEG-2 host-host protocol transmission.
