Compared to other business in mobile terminal, video traffic is quickly grown, and video traffic has larger bit Rate feature, video flow will become the key data source of the following mobile network.

Video original data sequence needs to carry out compressed encoding before network transmission, and the video compress being currently mainly used is compiled Code standard is H.264/ advanced video coding (Advanced Video Coding, AVC) or scalable video (Scalable Video Coding, SVC).No matter which kind of video encoding standard is used, with picture element unit cell group (Group Of Pictures, GOP) it is minimum code unit, data are mutually indepedent between GOP, i.e., can be according to reception Dynamic data exchange in receiving end Decoding and reconstituting obtains video image, and there are correlations for the video interframe in GOP, is divided into tri- kinds of frame types of I, P, B, in addition to this, There are also the coding control parameters used for decoder in GOP, wherein I frame is intra-coded frame, can independently be decoded, P frame be it is preceding to Predict frame, need to rely on I frame could decode, and B frame is two-way interpolation frame, and need to rely on I frame or P frame could decode.For above-mentioned four Seed type information, the data packet (i.e. one section of bit sequence) of same length are different to the influence degree of receiving end decoding and reconstituting , arrangement is followed successively by coding control parameters, I frame, P frame, B frame from high to low.

SVC is as extended version H.264/AVC, and SVC is by a video sequence coding at including multiple interdependences The data flow of layer, wherein the bottom is known as Primary layer (Base Layer, BL), can restore the video image of most basic quality, base It is enhancement layer (Enhancement Layer, EL) in the upper layer of Primary layer, the picture quality of video can be enhanced.In the coding of SVC Under mode, all EL must rely on BL and could decode, if there is multiple EL, need to rely on the EL ability of low layer in high-rise EL Decoding.In actual video service system, according to the particular demands of user, the sublayer of respective numbers is extracted from data flow (i.e. subcode stream), to realize the control of video output bit rate.

Not only shared flow-rate ratio is great for video traffic, and in video traffic different layers to receiving end video recovery effect Influence degree is inconsistent.For example, not being the average data and EL occurred in BL in bit-errors under same bit error rate scene Data in the case where, when less data of the generation in BL of bit-errors, the recovery effects of video data can be remarkably reinforced, Because the data that the decoding error of the data of BL does not only result in BL can not be restored, the number even if the EL being properly received also will affect According to.But the biography of evolved base station (evolved NodeB, eNB) side downlink user face data in existing LTE access net What multiplexing generated in defeated mechanism, in each Transmission Time Interval (Transmission Time Interval, TTI) includes same Media access control (Media Access Control, MAC) protocol Data Unit of video traffic difference layer data That (Protocol Data Unit, PDU) is all made of in the processing of physical layer is impartial error protection (Equal Error Protection, EEP), the probability that bit-errors occur for this data that will lead to different layers in same video traffic data is identical, Stronger error protection can not be assigned to the data of BL under the conditions of equivalent network, so that can reduce video transmits matter end to end Amount.
