Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The embodiment of the present invention provides a kind of data message for the framework that 3G-H.324M protocol stacks operate in Modem sides
Processing method, can to obtain video data stream carry out correct framing.As shown in figure 1, methods described includes following step
Suddenly：
101st, first processor obtains code/decode type from second processing device end.
Before first processor obtains video data stream from second processing device end, first processor is from second processing device end
Obtain code/decode type.The frame header of the video data stream transmitted in video call process defined in the code/decode type
Knowledge information.
102nd, first processor carries out framing according to frame head identification information pair video data stream.
First processor obtains video data stream from second processing device end, and with the frame head identification information in code/decode type
It is foundation, searches the frame head byte in video data stream, a data is obtained according to former and later two frame head bytes for finding
The frame length of frame, and framing is carried out to the data frame.
103rd, first processor is decoded to the data frame after framing.
First processor is decoded to the data frame after framing, is then played out over the display.Due to decoding
Data frame is a data frame for complete frame length, so the image shown after decoding is not in discontinuous mosaic or picture
Etc. phenomenon.
In actual applications, the processing method of video data provided in an embodiment of the present invention can apply to video calling skill
In art, the first processor can be that the second processing device can be baseband chip using treatment (AP) chip
(Modem), the application process chip and the baseband chip can be placed within an electronic equipment and video data is flowed into
Row treatment, it is also possible to be respectively placed within two electronic equipments and perform respective function respectively each other with data interaction energy
Power.In embodiments of the present invention, the application process chip and the baseband chip are based on 3G-H.324M protocol stacks to video counts
Processed according to stream, accessible data type include but are not limited to H.263, MPEG4 and H264, meanwhile, in practical application
The protocol stack that treatment video data stream can be based on is also not limited to 3G-H.324M.
In the prior art, because 3G-H.324M protocol stacks operate in baseband chip side, so cannot be obtained using process chip
Know the frame length of each data frame, data frame cannot be decoded according to frame length during decoding.Thereby resulting in application process chip will
A part for one frame or a few frames are decoded as a data frame, cause decoding error influence display effect.Frequently occur
Mosaic and the discontinuous phenomenon of picture are for the requirement of real-time such as Video chat video data service higher can not
Receive.
The processing method of video data provided in an embodiment of the present invention, can obtain the code/decode type of baseband chip side simultaneously
Therefrom obtain frame header and know information, the frame head byte in information searching video data stream is identified according to the frame head, in this, as
Framing carries out framing according to the video data stream for receiving, and video data stream is decoded according to correct frame length then,
The situation for avoiding the occurrence of reduction service quality such as mosaic (Quality of Service, abbreviation QoS) occurs.
Further, the embodiment of the present invention additionally provides a kind of processing method of video data, and methods described is to Fig. 1 institutes
Show further expanding for method, as shown in Fig. 2 methods described comprises the following steps：
201st, first processor obtains code/decode type from second processing device end.
This step is identical with the implementation of step 101 shown in Fig. 1, and here is omitted.
Additionally, first processor can also obtain decoding configuration information (Decoder when code/decode type is obtained
Configuration Information abbreviation DCI), the DCI is used for the decoding of subsequent data frame.It should be noted that
It is related to the DCI in the decoding process of MPEG4 types and H264 types, and is not H.263 related in the decoding process of type described
DCI.For the data flow of MPEG4 types, the DCI includes：Virtual objects VO, virtual objects sequence VOS, video object layer
VOL and object video group layer GVOP；For the data flow of H264 types, the DCI includes：Sequence parameter set SPS and image
Parameter set PPS.
202nd, the standard frame header that first processor is obtained in frame header knowledge information is known.
First processor obtains the knowledge of standard frame header from the frame head identification information defined in the code/decode type, described
Standard frame header is known for identifying frame head byte.
203rd, first processor knows the traversal frame head mark in video data stream according to standard frame header.
First processor obtains video data stream from second processing device end, and according to the order for receiving video data stream one by one
Each byte is traveled through, frame head byte is obtained according to traversing result.Specifically：Whether first processor judges taken in byte
Band frame head mark, if not carrying frame head mark, the byte is not frame head byte；If carrying frame head mark, will
The frame head mark is compared with standard frame header knowledge, if frame head mark is known not with the standard frame header
Together, then the byte is not frame head byte, if frame head mark is sensible with the standard frame header same, the byte is frame head
Byte.
204th, first processor is split between frame head byte and postamble byte.
After frame head byte is found, first processor is split between frame head byte and postamble byte, the frame
Trail byte is the previous byte adjacent with the frame head byte, and before the frame head byte to the frame head byte is adjacent
At least one byte before frame head byte constitutes a data frame.It should be noted that the frame head byte is next data
The start byte of frame, the postamble byte is the last bit byte of a upper data frame.
As shown in figure 3, first processor order is traveled through to ten bytes of numbering 1 to 10, wherein ten bytes
Frame head mark is followed successively by G1, S2, NF3, A1, H475, D8, E48, G23, A1 and KJ78.The standard frame head that first processor is obtained
A1 is designated, then when first processor traverses No. 4 bytes, the frame head mark of No. 4 bytes is sensible with standard frame header same, 4
Number byte is frame head byte.First processor is split between No. 3 bytes and No. 4 bytes, if by data where No. 4 bytes
Frame identification is 1 number frame, then No. 3 bytes are the postamble byte of 0 number frame, and No. 4 bytes are the frame head word of 1 number frame
Section.When first processor traverses No. 9 bytes, No. 9 bytes are similarly frame head byte, and first processor is in No. 8 bytes and No. 9
Split between byte, No. 8 bytes are the postamble byte of 1 number frame, No. 9 bytes are the frame head byte of 2 number frames.By
This completes the framing to 1 number frame, then proceeds framing to subsequent byte according to identical traversal and partitioning scheme.
It should be noted that the standard frame header that is used of different type video data stream framing knows different, thus framing
Result it is also different.Additionally, the length of data frame determines that same type is regarded by the byte position that carrying standard frame header is known
The length of multiple data frames that frequency data stream framing goes out is not exactly the same.
205th, first processor is decoded to the data frame after framing.
First processor is decoded according to the order of framing to data frame, such as the framing situation shown in Fig. 3, the
One processor order is decoded to 0 number frame, 1 number frame, 2 number frames.Optionally, in the decoding to data frame
Cheng Zhong, the DCI information auxiliary decoders that first processor can be to obtain in step 201, specific implementation does not do excessive introduction.
Decoded data frame is converted to corresponding picture signal and is displayed on screen, such as HDTV, can be with
Signal is simultaneously to be converted to HDMI (High Definition Multimedia Interface, abbreviation HDMI)
It is displayed on the screen of HDTV.Because first processor is the decoding that is carried out to data frame according to correct frame length, so
Situations such as being not in discontinuous picture or mosaic.And in the prior art, by taking screen 20 frames of display per second as an example：Show per frame
The when a length of 0.05s for showing, if it is 0s to set the initial time for starting to show the first frame.If first processor is by the 4th frame and the 5th frame
Decoded as a frame, then screen (can show the time of the 4th frame) by the 4th frame and the 5th frame during 0.15s to 0.20s
Shown as a frame, and do not show any frame during it should show the 0.20s to 0.25s of the 5th frame, thus caused
Occurs mosaic during 0.15s to 0.20s, the phenomenon for occurring picture stagnation during 0.20s to 0.25s.
Optionally, after first processor often travels through a byte, frame length counter can be added 1, when frame length counter
When numerical value reaches default frame length maximum (such as 6), then first processor reaches default frame length maximum in frame length counter
The byte of last traversal is defined postamble byte before, and the latter byte adjacent with quasi- postamble byte is defined frame head byte, first
Processor is split between quasi- frame head byte and quasi- postamble byte, at least one byte composition one before quasi- frame head byte
Individual data frame.
Above-mentioned quasi- frame head byte only exists dividing for statement with foregoing frame head byte, and frame head byte is to be known according to standard frame header
The frame head byte for finding, and quasi- frame head byte is the frame head byte found according to frame length counter, both are substantially identical, all
It is frame head byte.Only for ease of statement, both should not have different in practical application for above-mentioned differentiation.
Due to the reason such as loss in transmitting procedure, frame head mark may not be carried in video data stream byte, now needed
Frame length maximum rule carries out framing to video data stream.The length of each frame is frame length maximum (such as 6).Specifically, such as
Shown in Fig. 4,15 bytes of numbering 1 to 15 do not carry frame head mark, first processor frame length meter when No. 1 byte is traveled through
Number device is 0.Time frame long counter just plus 1 by first processor after often traveling through 1 byte.When first processor has traveled through No. 6 words
After section, frame length counter reaches maximum 6, then No. 6 bytes are the quasi- postamble byte of 1 number frame, and No. 7 bytes are 2 numbers
The quasi- frame head byte of frame.First processor is split between No. 6 bytes and No. 7 bytes, and by frame length counter O reset.So
Proceed traversal since No. 7 bytes afterwards, thus constitute 2 number frames, 3 number frames, 4 number frames ...
Compared with the framing mode shown in Fig. 3, framing mode group shown in Fig. 4 data frame frame length fixing phase out
Together, it is the maximum of frame length counter.
Further, can be combined with the technical scheme shown in Fig. 3 and Fig. 4 carries out framing to video data stream.Such as Fig. 5 institutes
Show, first processor receives 15 bytes of numbering 1 to 15 successively, wherein the frame head mark that No. 2 bytes and No. 9 bytes are carried
It is sensible with standard frame header same, frame head byte is all, remaining byte does not carry frame head mark, and default frame length maximum is 6.
First processor traverses No. 2 bytes for frame head byte, between No. 1 byte and No. 2 bytes split and obtains 0 number frame
Afterwards, by frame length counter O reset, then begun stepping through (No. 2 bytes are traversed 2 times) from No. 2 bytes.When first processor traversal
After complete No. 7 bytes, frame length counter reaches maximum, first processor using No. 7 bytes as 1 number frame quasi- postamble word
Section, is split between No. 7 bytes and No. 8 bytes, obtains 1 number frame, and by frame length counter O reset.Then from No. 8
Byte begins stepping through.When first processor traverses No. 9 bytes, it is found that No. 9 bytes are frame head byte, then in No. 8 bytes and 9
Split between number byte, obtained only No. 82 number frames of bytes composition, by that analogy it.
In the implementation shown in Fig. 5, after first processor is split between postamble byte and frame head byte, and
It is required for frame length counter O reset after splitting between quasi- postamble byte and quasi- frame head byte, as long as that is, first processor is carried out
Segmentation, just by frame length counter O reset.Although do so can produce indivedual ultrashort data frames (such as 2 number frames), can
Ultra-long data frame is avoided the occurrence of with the basis of framing is known according to standard frame header.From from the point of view of Consumer's Experience, ultrashort number
According to the picture caused by frame accelerate the utilities cost that is caused to user much smaller than the picture caused by ultra-long data frame stop to
The utilities cost that family is caused, so the appearance of indivedual ultrashort data frames can be received in practical application.
Frame head mark packet described in the embodiment of the present invention is included but is not limited to code/decode type.
The processing method of video data provided in an embodiment of the present invention, can obtain the code/decode type of baseband chip side simultaneously
Therefrom obtain frame header and know information, the frame head byte in information searching video data stream is identified according to the frame head, in this, as
