Embodiment
In the following description, in order to make reader understand the application better, many ins and outs have been proposed.But, persons of ordinary skill in the art may appreciate that even without these ins and outs and the many variations based on following execution mode and amendment, also can realize the each claim of the application technical scheme required for protection.
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
First the several concepts that the present invention relates to are made an explanation:
Video-splicing technology: be the technology that has the video of lap to be combined into one section of large-scale seamless high-resolution video by several sections.
Transcoding: refer to audio, video data is converted to another kind of encapsulation format or coded format from a kind of encapsulation format or coded format.
Real-time transcoding: the frame per second that refers to the video data before and after transcoding meets full frame rate, and in transcoding process, the transcoding time of unit data faster than or equal to wait for the input speed of transcoding unit data.
First embodiment of the invention relates to a kind of real-time transcoding method.Fig. 1 is the schematic flow sheet of this real-time transcoding method.
Specifically, as shown in Figure 1, this real-time transcoding method comprises the following steps:
In step 101, a complete picture is cut into N sprite, N is more than or equal to 2 integer.
Preferably, in the present embodiment, complete picture is that the multichannel code stream from multiple video cameras is stitched together, and removes the picture that lap forms.
In addition be appreciated that, but not as limit, the ultrahigh resolution vision signal obtaining with any means can be used in this real-time transcoding method.
Further, preferably, between N sprite, there is no lap.
In addition, being appreciated that in some other execution mode of the present invention, can be also only to have the overlapping N of a small part sprite.
In the present embodiment, preferably, N=4.
In addition, be appreciated that this be one preferred embodiment, in some other execution mode of the present invention, N can be also other integer, and not as limit.
Further, preferably, the resolution of complete picture is 7200*1080, and the resolution of each sprite is 1800*1080, and frame per second is Phase Alternation Line system full frame rate.
In present embodiment, horizontally-spliced as example taking 4 road 1080P video cameras execution, splicing length reaches 4*1920=7680 pixel, and width is still 1080 pixels.Due in the process of splicing, the lap of 4 road video datas and adjacent video need to be overlaped, so, suppose that the resolution of the ultrahigh resolution vision signal forming after splicing is 7200*1080, frame per second still keeps the frame per second before splicing, is still 25 frame/seconds.
What after video-splicing, form is all generally high-resolution or ultrahigh resolution picture, if keep full frame rate or the high frame per second of the front video of splicing, cannot carry out real-time coding with existing processor ability.
By ultrahigh resolution picture being cut into the sprite of normal resolution, can use the processor of main flow to carry out real-time coding, and as long as use multicomputer system or uniprocessor multiple nucleus system, just can realize the parallel real-time coding to multichannel sprite.
After this enter step 102, real-time coding walks abreast N sprite in multiple processors or multiple processor cores.
After this enter step 103, together with the Information encapsulation of the coding result of N sprite and this N sprite relative position relation of expression.
After this process ends.
Data after the coding of N road are unified to encapsulation, use Program Stream(PS) or Transport Stream(TS) this type of allows the encapsulation format of multichannel element flow, in the process of encapsulation, the private data that can use encapsulation format standard to allow is stamped mark to each road element flow, for identifying the position of this road video pictures at whole splicing picture.
Just the sprite of the N after real-time coding is carried out to simplified package together here.
By ultrahigh resolution picture is cut into multiple sprites, and then to the walk abreast method of real-time coding of multiple sprites, fully a benefit CPU or multi-core CPU complete ultrahigh resolution picture real-time transcoding.
This real-time transcoding method not only can be applied in the video monitoring that has multiple video cameras, also can be applied in cell phone system, for example present multinuclear mobile phone.

Specifically, as shown in Figure 2, this real-time decoding method comprises the following steps:
In step 201, the encapsulation of data that comprises N sprite is carried out to decapsulation, this encapsulation of data comprises the information that represents this N sprite relative position relation, N is more than or equal to 2 integer.
Preferably, encapsulation of data is to utilize real-time transcoding method in first embodiment of the invention by the formed encapsulation of data that is packaged together after parallel N sprite real-time coding.
After this enter step 202, in multiple processors or multiple processor cores to the N the parsing sprite real-time decoding that walks abreast.
After this enter step 203, according to the information that represents this N sprite relative position relation, the decoded result of N sprite is spliced into a complete picture again.
After this process ends.
Specifically, the resolution of complete picture is 7200*1080, and the resolution of each sprite is 1800*1080, and frame per second is Phase Alternation Line system full frame rate.
In first embodiment of the invention, utilize real-time transcoding method that a complete picture is cut into N sprite, formed encapsulation of data is just packaged together after the parallel real-time coding of N sprite in multiple processors or multiple processor cores.In the present embodiment, utilize above-mentioned real-time decoding method to carry out real-time decoding to the encapsulation of data forming in the first execution mode.

Iv) splicing combined-flow data can, for Internet Transmission or storage, be convenient to follow-up application.
6, receive after above-mentioned combined-flow data, we carry out following steps, again represent splicing picture, see shown in Fig. 8 flow chart.
I) resolve according to the encapsulation format of data;
Ii) to representing that the data of different pictures divide other framing and decoding;
Iii) data after the decoding of not going the same way are stored in to data to be displayed buffering according to the position in splicing picture, it should be noted that, this step, after need to waiting for that 4 synchronous road picture datas are all stored in data to be displayed buffering, could carry out next step.Owing to changing in splicing in the process of face cutting coding, execution be simple cutting, after this step is spliced again, still retained the seamless spliced effect of splicing picture.
Iv) play up the data in data to be displayed buffering, the display effect of splicing picture.
Six above-mentioned steps, have comprised ultrahigh resolution video real-time transcoding after video-splicing, and the complete procedure that after transcoding, data playback shows.
Innovative point of the present invention has been to propose a kind of ultrahigh resolution video in the method that ensures to carry out under full frame rate (high frame per second) prerequisite real-time transcoding, solve in prior art and can only carry out video-splicing acquisition ultrahigh resolution picture, still cannot carry out the defect of ultrahigh resolution picture real-time transcoding.
