Embodiment Construction

[0082] Before introducing the embodiments of the present application, the relevant technical terms involved in the present application are firstly explained.

[0083] Video decoding (video decoding): refers to the process of restoring the code stream into a reconstructed image according to specific grammatical rules and processing methods.

[0084] Video encoding (video encoding): refers to the process of compressing an image sequence into a code stream.

[0085] Video coding (video coding): the collective name of video encoding and video decoding, the Chinese translation is the same as video encoding.

[0086] Panoramic video: It can also be called virtual reality (virtual reality, VR) panoramic video, or 360-degree panoramic video or 360-degree video. At any time, you can adjust the video up, down, left, and right to watch at will.

[0087] Tile: Refers to the block-shaped coding area obtained by dividing the image to be encoded in the video coding standard HEVC. A frame o...

Abstract

The embodiment of the invention provides a media information processing method and device, relates to the technical field of streaming media transmission. The method and the device are used for savingtransmission bandwidth and reducing complexity of streaming management. The method comprises: acquiring sub-code stream data, the sub-code stream data comprising indication information, the indication information being used for indicating the number of tile data included in the sub-code stream data, or the indication information being used for indicating whether the sub-code stream data can be used for splicing or not; and processing the sub code stream data according to the indication information.

Description

technical field [0001] The embodiments of the present application relate to the technical field of streaming media transmission, and in particular, to a method and device for processing media information. Background technique [0002] Currently, with the increasing popularity of viewing applications of virtual reality (virtual reality, VR) videos such as 360-degree videos, more and more users join in the experience team of watching VR videos with a large viewing angle. While this new video viewing application brings a new video viewing mode and visual experience to users, it also brings new technical challenges. In the process of watching a video with a large viewing angle such as 360 degrees, the spatial area of ​​the VR video is a 360-degree panoramic space, which exceeds the normal visual range of the human eye. Therefore, the user will change the viewing angle (or angle of view). The video images seen by the user will be different depending on the viewing angle of view...
