Embodiment Construction

[0028] 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.

[0029] figure 1 It is an overall flowchart of the codec method according to the first embodiment of the present invention.

[0030] In step S100, the user interface module receives the original data from the outside, and defines the data encoding format and data encapsulation format required by the user according to the user's input, specifically, the user interface module can receive the original data to be transcoded from the outside , and according to the user's input information, define the data encoding format and data encapsulation format required by the user, and then call the conversion system of the corresponding data encoding format and data encapsulation ...

Abstract

The invention provides a coding and decoding system and method which comprises the steps that: a user interface module receives original data from outside, and defines a data coding format and a data packaging format which are required according to the input of the user; a format identification module identifies an original packaging format of original data; a separator matched with the original packaging format of the original data in the plurality of separators is used for separating the original data; a data processing module decodes the separated original data and codes the decoded data according to the required data coding format of the user; and a packaging module packages the coded data into data required by the user according to the data packaging format required by the user. According to the coding and decoding system and method, in accordance with the actual demand of the user, the original data with one or more formats is transcoded into data with one or more formats required by the user, thus different demands of the user are met, and storage resources required by storing data with multiple formats are reduced. The user does not participate into the transcoding process, the workload of the user is lightened.

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 ...
