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 clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The framework that the embodiment of the present invention operates in Modem side for 3G-H.324M protocol stack provides a kind of processing method of data message, can carry out correct framing to the video data stream of obtaining.As shown in Figure 1, described method comprises the steps:
101, first processor obtains code/decode type from the second processor end.
Before first processor obtains video data stream from the second processor end, first processor obtains code/decode type from the second processor end.In described code/decode type, defined the frame head identification information of the video data stream of transmitting in video call process.
102, first processor carries out framing according to frame head identification information to video data stream.
First processor obtains video data stream from the second processor end, and the frame head identification information of take in code/decode type is foundation, search in video data stream frame head byte, according to former and later two frame head bytes that find, obtain the frame length of a Frame, and this Frame carried out to framing.
103, the Frame of first processor after to framing decoded.
The Frame of first processor after to framing decoded, and then on display, plays.Because the Frame of decoding is the Frame of a complete frame length, so the phenomenon such as the image showing after decoding there will not be mosaic or picture is discontinuous.
In actual applications, the processing method of the video data that the embodiment of the present invention provides can be applied in video calling technology, described first processor can be processed (AP) chip for application, described the second processor can be baseband chip (Modem), described application process chip and described baseband chip can be placed within an electronic equipment video data stream is processed, and also can be placed in respectively within two electronic equipments, to carry out respectively function separately and have each other data exchange capability.In embodiments of the present invention, described application process chip and described baseband chip are processed video data stream based on 3G-H.324M protocol stack, H.263 accessible data type includes but are not limited to, MPEG4 and H264, meanwhile, in practical application processing video data stream can based on protocol stack be also not limited to 3G-H.324M.
In prior art, because 3G-H.324M protocol stack operates in baseband chip side, so application process chip cannot be known the frame length of each Frame, during decoding, cannot to Frame, decode according to frame length.Cause thus application process chip that a part for one frame or a few frame are decoded as a Frame, causing decoding to make mistakes affects display effect.Frequent mosaic and the discontinuous phenomenon of picture occurring is unacceptable for the higher video data service of the requirement of real-times such as Video chat.
The processing method of the video data that the embodiment of the present invention provides, can obtain the code/decode type of baseband chip side and therefrom obtain frame head identification information, according to the frame head byte in described frame head sign information searching video data stream, using this as framing according to the video data stream receiving is carried out to framing, then according to correct frame length, video data stream is decoded, the situation of avoiding occurring the reduction service quality such as mosaic (Quality of Service is called for short QoS) occurs.
Further, the embodiment of the present invention also provides a kind of processing method of video data, and described method is that as shown in Figure 2, described method comprises the steps: to the further expanding of method shown in Fig. 1
201, first processor obtains code/decode type from the second processor end.
This step is identical with the implementation of step 101 shown in Fig. 1, repeats no more herein.
In addition, first processor can also obtain decoding configuration information (Decoder Configuration Information is called for short DCI) when obtaining code/decode type, and described DCI is for the decoding of subsequent data frame.It should be noted that, in the decode procedure of MPEG4 type and H264 type, relate to described DCI, and H.263 in the decode procedure of type, do not relate to described DCI.For the data flow of MPEG4 type, described DCI comprises: virtual objects VO, virtual objects sequence VOS, video object layer VOL and object video group layer GVOP; For the data flow of H264 type, described DCI comprises: sequence parameter set SPS and picture parameter set PPS.
202, the standard frame leader that first processor obtains in frame head identification information is known.
In the frame head identification information that first processor defines from described code/decode type, obtain standard frame leader and know, described standard frame leader knowledge is used for identifying frame head byte.
203, first processor is identified at and in video data stream, travels through frame head sign according to standard frame head.
First processor obtains video data stream from the second processor end, and one by one each byte is traveled through according to the order of receiving video data stream, according to traversing result, obtains frame head byte.Concrete: first processor judges in byte whether carry frame head sign, if do not carry frame head sign, this byte is not frame head byte; If carried frame head sign, described frame head sign is known and compared with described standard frame leader, if described frame head sign is known different from described standard frame leader, this byte is not frame head byte, if described frame head sign is sensible same with described standard frame leader, this byte is frame head byte.
204, first processor is cut apart between frame head byte and postamble byte.
After finding frame head byte, first processor is cut apart between frame head byte and postamble byte, described postamble byte is the previous byte adjacent with described frame head byte, and at least one byte that described frame head byte arrives before an adjacent frame head byte before described frame head byte forms a Frame.It should be noted that, the start byte that described frame head byte is next Frame, described postamble byte is the last bit byte of a upper Frame.
As shown in Figure 3, first processor order travels through numbering ten bytes of 1 to 10, and wherein the frame head of ten bytes sign is followed successively by G1, S2, NF3, A1, H475, D8, E48, G23, A1 and KJ78.The standard frame head that first processor obtains is designated A1, and, when first processor traverses No. 4 bytes, the frame head of No. 4 bytes sign is sensible same with standard frame leader, and No. 4 bytes are frame head byte.First processor is cut apart between No. 3 bytes and No. 4 bytes, if No. 4 byte place Frames are designated to 1 number frame, and the postamble byte that No. 3 bytes are 0 number frame, No. 4 bytes are the frame head byte of 1 number frame.When first processor traverses No. 9 bytes, No. 9 byte is similarly frame head byte, and first processor is cut apart between No. 8 bytes and No. 9 bytes, and No. 8 bytes are the postamble byte of 1 number frame, and No. 9 bytes are the frame head byte of 2 number frames.Complete thus the framing to 1 number frame, then according to identical traversal and partitioning scheme, subsequent byte is proceeded to framing.
It should be noted that, the standard frame leader that dissimilar video data stream framing is used is known different, and the result of framing is also different thus.In addition, the length of Frame determines by carrying the byte position that standard frame leader knows, and the length of a plurality of Frames that same type video data stream framing goes out is strictly not identical.
205, the Frame of first processor after to framing decoded.
First processor is decoded to Frame according to the order of framing, and for example, for the framing situation shown in Fig. 3, first processor order is decoded to 0 number frame, 1 number frame, 2 number frames.Optionally, in to the decode procedure of Frame, first processor can be with the DCI information auxiliary decoder obtaining in step 201, and specific implementation is not done too much introduction.
Decoded Frame is converted to corresponding picture signal and is presented on screen, for example, for HDTV (High-Definition Television), can be converted to HDMI (High Definition Multimedia Interface) (High Definition Multimedia Interface is called for short HDMI) signal and be presented on the screen of HDTV (High-Definition Television).Because first processor is the decoding of Frame being carried out according to correct frame length, so there will not be the situations such as the discontinuous or mosaic of picture.And in the prior art, the screen of take demonstration 20 frames per second are example: the duration that every frame shows is 0.05s, starts to show that the initial time of the first frame is 0s if establish.If first processor is decoded the 4th frame and the 5th frame as a frame, screen can be during 0.15s to 0.20s (time that shows the 4th frame) the 4th frame and the 5th frame are shown as a frame, and during the 0.20s to 0.25s that should show the 5th frame, do not show any frame, cause thus during 0.15s to 0.20s, occurring mosaic, during 0.20s to 0.25s, occur the phenomenon that picture is stagnated.
Optionally, after byte of the every traversal of first processor, frame length counter can be added to 1, for example, when the numerical value of frame length counter reaches default frame length maximum (6), the byte of first processor last traversal before frame length counter the reaches default frame length maximum postamble byte that is as the criterion, a rear byte adjacent with the accurate postamble byte frame head byte that is as the criterion, first processor is cut apart between accurate frame head byte and accurate postamble byte, and at least one byte before accurate frame head byte forms a Frame.
Only there is dividing of statement in above-mentioned accurate frame head byte and aforementioned frame head byte, frame head byte is for know the frame head byte finding according to standard frame leader, and the frame head byte of accurate frame head byte for finding according to frame length counter, both essence is identical, is all frame head byte.Above-mentioned differentiation is only for ease of statement, and in practical application, both do not have different.
Owing to the reason such as losing in transmitting procedure, in video data stream byte, may not carry frame head sign, now need frame length maximum rule to carry out framing to video data stream.The length of each frame is frame length maximum (for example 6).Concrete, as shown in Figure 4, to number 15 bytes of 1 to 15 and all do not carry frame head sign, first processor is 0 at No. 1 byte time frame long counter of traversal.After 1 byte of the every traversal of first processor, just time frame long counter is added to 1.When first processor has traveled through after No. 6 bytes, frame length counter reaches maximum 6, the accurate postamble byte that No. 6 bytes are 1 number frame, and No. 7 bytes are the accurate frame head byte of 2 number frames.First processor is cut apart between No. 6 bytes and No. 7 bytes, and by frame length counter O reset.Then since No. 7 bytes, proceed traversal, form thus 2 number frames, 3 number frames, 4 number frames ...
Compare with the framing mode shown in Fig. 3, the Frame frame length that the framing mode shown in Fig. 4 is organized is out fixing identical, is the maximum of frame length counter.
Further, can also to video data stream, carry out framing in conjunction with the technical scheme shown in Fig. 3 and Fig. 4.As shown in Figure 5, first processor receives numbering 15 bytes of 1 to 15 successively, the frame head sign that wherein No. 2 bytes and No. 9 bytes are carried and standard frame leader sensible with, be all frame head byte, all the other bytes are not all carried frame head sign, and default frame length maximum is 6.It is frame head byte that first processor traverses No. 2 bytes, cuts apart and obtains after 0 number frame, by frame length counter O reset, then since No. 2 byte traversals (No. 2 byte is traversed 2 times) between No. 1 byte and No. 2 bytes.When first processor has traveled through after No. 7 bytes, frame length counter reaches maximum, and the accurate postamble byte of first processor using No. 7 bytes as 1 number frame cut apart between No. 7 bytes and No. 8 bytes, obtains 1 number frame, and by frame length counter O reset.Then since No. 8 byte traversals.When first processor traverses No. 9 bytes, find that No. 9 bytes are frame head byte, between No. 8 bytes and No. 9 bytes, cut apart, the 2 number frames that obtain only having No. 8 bytes to form, by that analogy it.
In the implementation shown in Fig. 5, when first processor is after cutting apart between postamble byte and frame head byte, and all need frame length counter O reset after cutting apart between accurate postamble byte and accurate frame head byte, need only first processor and cut apart, just by frame length counter O reset.Although do like this, can produce indivedual ultrashort Frames (for example 2 number frames), can on the basis of knowing framing according to standard frame leader, avoid occurring ultra-long data frame.The angle of experiencing from user, the effectiveness loss that the effectiveness loss that the caused picture of ultrashort Frame accelerates that user is caused stops user causing much smaller than the caused picture of ultra-long data frame, so can accept the appearance of indivedual ultrashort Frames in practical application.
Frame head sign packets of information described in the embodiment of the present invention is drawn together but is not limited to code/decode type.
The processing method of the video data that the embodiment of the present invention provides, can obtain the code/decode type of baseband chip side and therefrom obtain frame head identification information, according to the frame head byte in described frame head sign information searching video data stream, using this as framing according to the video data stream receiving is carried out to framing, then according to correct frame length, video data stream is decoded, avoid the situation that occurs the reduction QoS such as mosaic to occur.
In addition, while not carrying frame head sign in video data stream byte, the processing method of the video data that the embodiment of the present invention provides, can also carry out framing to video data stream byte according to frame length maximum rule, avoid occurring ultra-long data frame, can further improve the QoS quality of video playback.
