Live video stream transcoding system

Abstract

The invention discloses a live video stream transcoding system comprising a pickup and an image acquisition device which are positioned in a video recording room, wherein a first decoder is connected with the output ends of the pickup and the image acquisition device, a sound signal is divided into a plurality of sub-sound signals via the first decoder that is connected with a sub-sound unit used for storing the sub-sound signals; an image signal is divided into a plurality of sub-image signals via the first decoder that is connected with a sub-image unit used for storing the sub-image signals; the first decoder is connected with a catalog unit used for storing catalogs; a storage module is connected with the output end of the first decoder; the output end of the storage module is connected with the input end of the control module; and the output end of the control module is connected with an input end of a retrieval module. According to the system provided by the invention, work difficulty is reduced, and unsynchronized pictures and characters can be adjusted to be synchronous.

Description

technical field [0001] The present invention relates to the technical field of transcoding, in particular to a live video streaming transcoding system. Background technique [0002] With the development of science and the progress of society, modern equipment is gradually entering people's lives. Modern equipment not only makes people's life more convenient, but also promotes the progress of human society. [0003] Video transcoding (Video Transcoding) refers to the conversion of a compressed and encoded video stream into another video stream to adapt to different network bandwidths, different terminal processing capabilities, and different user needs. Transcoding is essentially a process of first decoding and then encoding, so the code stream before and after conversion may or may not follow the same video coding standard. [0004] In the process of transcoding the video live broadcast system under the existing technology, the video is usually temporarily decoded first, an...

Problems solved by technology

[0004] In the process of transcoding the video live broadcast system under the existing technology, the video is usually temporarily decoded first, and then re-encoded into the required format and data encoding speed. The video occupies a large space, which increases the difficulty of transcoding, and often occurs decoding The picture and text displayed in the final file are out of sync, and the out-of-sync picture and text cannot be adjusted
