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 by 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 the overlay content that is fit to be inserted in the main video frequency program.
Described 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, at 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 described overlay content signal.That is,, can there be the corresponding matching class parameter of the correlativity of instruction content and specific classification at each classification identifier.Then, if existing with the same category identifier is a plurality of overlay content signal of feature, if and this identifier and being complementary of being included in defined in the label in the main video streaming, will select to have the overlay content signal of the highest corresponding matching class parameter so.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 example embodiment of quality of fit parameter, label (for example both can have been appended to vision signal, at processor 29 places that tag) append to each (for example, at overlay content generator 26 places) in one or more overlay content signal again.Classification identifier can 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 at each classification identifier.Described quality of fit parameter can be indicated the relative correspondence between each overlay content and the classification identifier.In this example 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.
The selection and the insertion of overlay content can take place by the respective video processor 28 of described position at least one remote location place.Another is chosen as, and the selection and the insertion of overlay content can take place by video processor 28 in central position.Then, a plurality of copies through revising video content can be assigned to one or more remote locations to be used for further distribution from middle position.
Can distribute place place label to be appended to overlay content signal in central authorities by overlay content generator 26.This label can determine 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 into overlay content signal in the insertion window of vision signal the counterpart with the substitution video signal.Another is chosen as, and overlay content can 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 example embodiment among Fig. 3 according to video processor 28 of the present invention.The example embodiment of the video processor 28 shown in Fig. 3 comprises optional memory divider 30 and the optional video transrater 31 that is used for realizing to the modification of the data rate of video streaming in the insertion that overlay content takes place.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, video processor 28 can be embodied as the transfer capability that is provided by optional memory divider 30 and optional video transrater 31 is not provided.Another is chosen as, and video transrater 31 can be through structure to keep the raw data rate of vision signal.
In the example embodiment that needs are changed, memory allocator 30 can be at the bag that imports into of the header information scan video signal of regulation level of encoded image and vertical dimension (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 storer 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 and is used for and will be inserted into or covers the storer of the overlay content on the top of vision signal.At United States Patent (USP) 7,046, the example 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 RAM 33 via dynamic RAM Controller 32.By label being deposited to the arrival of notifying CPU (central processing unit) (CPU) 34 each bag in the reception information module 36 of communicating by letter with CPU 34.Described bag of described tag recognition and CPU 34 keep and make the address of bag in the dynamic RAM 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 determines frame is forwarded to from bag dynamic RAM 33 order of video transrater 31.The bag that CPU 34 indication dynamic RAM Controllers 32 will be selected by the expectation order is forwarded to video transrater 31 from bag dynamic RAM 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 described 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 as mentioned.Then, CPU 34 can instruct dynamic RAM Controller 32 to be provided to rate converter 31 from the suitable bag of bag dynamic RAM 33.For example, CPU 34 can instruct dynamic RAM Controller 32 will from bag dynamic RAM 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 does not need to 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 described 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 RAM 33 via dynamic RAM Controller 32.Simultaneously, notice CPU 34 each bag transmit.This finishes so that CPU 34 knows each position that wraps in the dynamic RAM 33 again by label being deposited to receive in the information module 36 again.In the case, rate converter 31 provides described 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.
Pre-adjustment has the video streaming of label or overlay content streams and 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 finish by revising.
If transmit main video signal in the different time with different resolution, so available different resolution sends identical overlay content.For example, " resolution " can be one in the parameter of definite " fit quality ", perhaps, can assign different classification ID at different resolution.
Be that the video that is transmitted by the DPI server during the described 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 dirigibility 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 what the subject classification of main program can utilize 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 by the overlay content that inserts event initiator at special time.If event/segment has many promoters, subject information can all use same category ID at it so, but has different " fit quality " parameters.Certainly, rotate in the overlay content if use to wish 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 feature with the full-motion video, bandwidth and memory requirement can become crucial so.In the case, transmitting these data in the time of more approaching actual insertion time via the MPEG-2 host-host protocol may be easier.
Fig. 4 shows being used for by covering the block scheme of system that generator 26 triggers the insertion of overlay contents of embodiment according to the present invention embodiment.There is multiple mode, as it will be apparent to those skilled in the art that in order to the insertion that triggers overlay content.Fig. 4 only shows some example in the various examples.Can use (for example) DVS 629 agreements to send by ad decision system (ADS) module 42 and cover the signal that inserts.DVS 629 is by digital video sub-committee of cable Telecommunications Engineer association (SCTE) (DVS) exploitation and in developing standard.ADS module 42 can use DVS 629 agreements to communicate by letter with covering generator 26 via the network switch 50.ADS 42 can send the profile of knowing overlay content to covering generator 26.In this way, can provide targeted advertisements.In other words, for identical network or ad content, can provide different overlay contents (for example, based on beholder's profile, demography, viewing time, viewing areas etc.) to different beholders.
Emergency alert system (EAS) coder module 45 can adopt (for example) SCTE 18 (SCTE standard) agreement to come to send emergency alert messages via the network switch 50 to covering generator 26.In this way, EAS coder module 45 can trigger the literal covering to existing video network.
Covering generator 26 also can be via the agreement of the network switch 50 employings from other form of module 48, as GUI, HTTP, SNMP etc.Accept the overlay content of variety of protocol form and realized that this commerce that overlay content is inserted is used and become real-time application to covering the live fast updating of literal or figure.
Be understood by those skilled in the art that,, also can give other effect of content through covering according to the present invention.
Now, should be appreciated that, the invention provides and be used for managing overlay content to the insertion of vision signal and be used to change have and insert and advantageous method, equipment and the system of the vision signal of covering power.
