Abstract:
A VR video transcoding method is disclosed. In the method, source VR video data is decoded to obtain an audio data set and a frame data set type one. The source VR video data and the frame data set type one have a source resolution. A frame data set type two and a third frame data are obtained from the frame data set type one. The frame data set type two and the frame data set type three have the same target resolution and are obtained by different manners. An enhancement data set is obtained by subtracting the frame data set type three from the frame data set type two. A base video set is obtained by combining and segmenting the frame data set type two and the audio data set. An enhancement video set is obtained by encoding and segmenting the enhancement data set. The base video set and the enhancement video set are used for VR video playbacks. The base video set and the enhancement video set are transmitted separately and combined with each other into video content to improve transmission efficiency.

Claim (Index 6):
The method according to  claim 1 , wherein the step of obtaining the base video set by combining and segmenting the frame data set type two and the audio data set comprises:\n combining the frame data set type two and the audio data set into at least one video with sound track; and obtaining the base video set by segmenting the at least one video with sound track in accordance with a timeline.
