Video processing method and equipment

Abstract

The embodiment of the invention provides video processing method and equipment. The video processing method comprises the following steps that: referring to an encoding and decoding unit capable of being decoded correctly by second equipment in the reference image buffering region of a self encoder, first equipment encodes original encoding and decoding unit or decoded encoding and decoding unit of video data into a P or B type encoding and decoding unit, wherein the encoding and decoding unit consists of a frame or a macro block; and the first equipment sends the encoded encoding and decoding unit to the second equipment. According to the embodiment of the invention, the first equipment re-encodes the video data of the frame or macro block with receiving types containing I and P (selectively B) types, and uses the P or B type as soon as possible in the re-encoding process, and sends the encoded video data to the second equipment, thus reducing the bandwidth resources occupied by video data, and also improving the user experience.

Description

technical field [0001] Embodiments of the present invention relate to the field of video technology, and in particular, to a video processing method and device. Background technique [0002] With the development of communication technology, the application of video in mobile network is more and more extensive. However, while video services provide rich information, they also occupy most of the system bandwidth and become a great pressure on operators, especially for mobile operators. Due to limited bandwidth, video services are likely to cause mobile network congestion, degrade video user experience, and affect other voice / data users. [0003] In existing video coding formats, there is a distinction between intra-coded frames and inter-frame coded frames. The intra-frame coded frame is an independently coded image, and the receiving end does not depend on other frame decoding; while the decoding of the inter-frame coded frame at the receiving end needs to rely on the previ...

Problems solved by technology

[0004] However, for IPPP... (or some coded as B frames in the middle) video data at intervals of I frames, there is a problem that the amount of video data is too large, it takes up more bandwidth resources, and the user experience is not good.

In addition, for I macroblocks, some current practices are to randomly insert I macroblocks in P frames or B frames to reduce the impact of transmission errors; however, these randomly inserted I macroblocks are Unnecessary, there is also the problem of occupying more bandwidth resources, and the corresponding user experience is not high
