Anti-jamming video transmission and reception method

Abstract

The present invention provides an anti-jamming video transmission and reception method, including a server-side transmission method: dividing each frame of a video program into a series of tile units that are tiled into the frame, and each tile unit is M*N the pixel matrix of each block unit; the pixels in each position in each block unit are sequenced to form MN pixels; the pixels with the same sequence number are extracted in each block unit to form a sub-picture of a frame corresponding to the block unit, A total of MN sub-pictures of the frame picture are obtained; the server side sends the sub-pictures of each frame picture to the client in turn, and the time interval between two adjacent frames in the video program is T. If the total transmission time of the sub-pictures of a certain frame picture reaches T, ignore the remaining sub-pictures of the frame, and directly transmit the sub-pictures of the next frame; Watch the picture effect in the best resolution.

Description

technical field [0001] The present invention relates to the field of network technology, in particular, to a video transmission and reception method. Background technique [0002] At present, in the process of network video transmission, after the request from the client, the server continuously transmits video programs with a specific resolution to the user according to the user's needs; during this process, the network transmission speed must be greater than the video playback speed of the client. In order to ensure that the video program does not freeze, otherwise the client needs to wait for buffering; when the network speed is not stable, the video program often freezes every few tens of seconds or even a few seconds, making the playback of the video program intermittent, seriously affecting viewing experience. [0003] In order to alleviate the above problems, the existing mechanism is to provide the user with a resolution selection function during the playback proces...

[0002] At present, in the process of network video transmission, after the request from the client, the server continuously transmits video programs with a specific resolution to the user according to the user's needs; during this process, the network transmission speed must be greater than the video playback speed of the client. In order to ensure that the video program does not freeze, otherwise the client needs to wait for buffering; when the network speed is not stable, the video program often freezes every few tens of seconds or even a few seconds, making the playback of the video program intermittent, seriously affecting viewing experience

[0003] In order to alleviate the above problems, the existing mechanism is to provide the user with a resolution selection function during the playback process, so that the user can select a lower resolution mode when the video freezes, so as to alleviate the freeze; but according to the current video encoding mode, which only provides a very limited number of resolutions, and cannot optimally adapt to the current network speed; and after the user selects the resolution, if the subsequent network speed improves, there is no automatic correction mechanism, which makes the user stay in a relatively long time. poor visual experience
