Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0039] The data encoding and decoding method of the embodiment of the present application can be applied to any computer equipment with encoding and decoding functions, so as to realize a reasonable selection of encoding and decoding methods, improve encoding and decoding efficiency, and reduce the processor occupied by encoding and decoding resource.

[0040] In the data encoding method of the embodiment of the present application, after the computer device determines the data set ...

Abstract

The invention discloses a data coding method and device and a data decoding method and device. According to the scheme, after a to-be-coded or to-be-decoded data set is determined, a data format set supported by a hard coder or a hard decoder is obtained; if untested data formats exist in the data format set, a target data format needing to be tested is selected; when a soft coder or a soft decoder is controlled to code or decode currently processed target data, the hard coder or the hard decoder is controlled to code or decode the target data based on the target data format; and if the data coded by the hard coder or the data decoded by the hard decoder is normal, the coding of the soft coder or the decoding of the soft decoder can be terminated, and the soft coder or the soft decoder isdirectly used for coding or decoding the unprocessed data in the data set. According to the scheme provided by the invention, coding and decoding modes can be selected reasonably, and a CPU occupationrate can be reduced to the greatest extent.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data encoding and decoding method and device. Background technique [0002] The application range of data encoding and decoding is very wide. For example, since audio and video files contain a large amount of data, in the case of audio and video file transmission, in order to reduce the amount of data transmitted by the network, audio and video files need to be After encoding, the encoded audio or video data is transmitted through the network; correspondingly, at the playback end that receives the encoded audio and video, the encoded audio and video data can be decoded to realize audio and video playback . [0003] At present, there are two types of data encoding and decoding: soft encoding and decoding and hard encoding and decoding. Among them, soft encoding and decoding refers to encoding or decoding using software algorithms; while hard encoding and d...
