Problems solved by technology

[0005] However, the data transcoding task is heavy, and it will take up too much server resources and time, so when the server performs the transcoding operation, the transcoding operation is slow
In addition, this technical solution also has the problem of out-of-sync audio and video

Embodiment Construction

[0024] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0025] figure 1 It is a flowchart of an encoding and decoding method according to an embodiment of the present invention. The codec method includes: in step S100, the user interface module receives the original data from the outside, and defines the data encapsulation format required by the user according to the user's input; in step S102, the separation module separates the original data into original audio data and original video data; in step S104, a plurality of conversion modules convert the original video data into video data required by the user; in step S106, the processing module synchronizes the original audio data corresponding to the video data required ...

Abstract

The invention provides an encoding and decoding method which comprises the following steps that: a user interface module receives original data from the outside and defines a data packaging format required by a user according to the input of the user; a separation module separates the original data into original audio data and original video data; a plurality of conversion modules convert the original video data into video data required by the user; a processing module adds synchronization parameters of the original audio data corresponding to the video data required by the user to a head part of the video data required by the user; and a packaging module packages the video data processed by the processing module and the original audio data into data required by the user according to the data packaging format required by the user. By parallel transcoding, the data conversion rate is greatly improved and time required for transcoding is shortened so as to meet the real-time requirement of the user; and moreover, the synchronous processing carried out before the audio and video data is packaged implements the effect that in the playing process of the transcoded data, the audio and video synchronization is kept.

Description

technical field [0001] The present invention generally relates to the field of computer technology, and more specifically relates to a data encoding and decoding system and method. Background technique [0002] With the continuous development of digital broadcasting and television, the demand for video transcoding technology continues to increase. The main application areas of transcoding technology are digital TV broadcasting and digital media front-end processing. [0003] At present, a large number of digital video programs are in MPEG-2 (Moving Pictures Experts Group-2, Moving Picture Experts Group) format, and many new playback devices adopt MPEG-4 / H.264 / Real / VC to improve transmission and storage efficiency. -1 / AVS and other advanced digital codec formats, so the transcoding technology derived from MPEG-2 has been widely used, and the requirements for high-definition transcoding related to this are getting higher and higher, especially real-time transcoding technology ...
