Abstract

The embodiments of the application provide encoding and decoding methods and devices for multidimensional video data. The encoding method includes the following steps: detecting the current network transmission parameters during the transmission of multidimensional video data, wherein the multidimensional video data includes M frames of original image data at the same time point; determining the number of images N according to the network transmission parameters; extracting N frames of original image data from the M frames of original image data according to the number of images N; and encoding the N frames of original image data to obtain N frames of target image data. Through the embodiments of the invention, the number of frames of original image data can be appropriately reduced according to the actual transmission situation, and thus, the occupation of bandwidth is reduced. In addition, as the occupation of bandwidth is reduced, the original image data can be encoded at a high bitrate, there is no need to encode the original image data at a low bit rate because of bandwidth limitation, and the resolution of multidimensional video data is ensured.

Description

Technical field [0001] This application relates to the technical field of video processing, in particular to a multi-dimensional video data encoding method, a multi-dimensional video data decoding method, a multi-dimensional video data encoding device and a multi-dimensional video data decoding device. Background technique [0002] With the popularity of the Internet, video data has become the main carrier medium for content. [0003] At present, video data has developed from two-dimensional video data to multi-dimensional video data, such as three-dimensional (3D) video data. The transmission of video data occupies most of the bandwidth of network transmission. It provides users with a rich experience while storing and Transmission pressure. [0004] If the video data is encoded with a high bit rate to maintain the clarity of the video data, it will take up more bandwidth. However, if the video data is encoded with a low bit rate to reduce the bandwidth occupation, it will lead to ...
