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 10):
A system for transcoding a VR video, comprising:\n a segmentation module, configured to decode source VR video data to obtain an audio data set and a frame data set type one, wherein the source VR video data and the frame data set type one have a source resolution; a first generating module, configured to obtain a frame data set type two from the frame data set type one; a second generating module, configured to obtain a frame data set type three from the frame data set type one, wherein the frame data set type two and the frame data set type three have the same target resolution and are obtained by different manners; a difference calculation module, configured to subtract the frame data set type three from the frame data set type two to obtain an enhancement data set; a combining and segmenting module, configured to combine and segment the frame data set type two and the audio data set to obtain a base video set; an encoding and segmenting module, configured to encode and segment the enhancement data set to obtain an enhancement video set, wherein the base video set and the enhancement video set are used for VR video playbacks; and a storage module, configured to store the base video set and the enhancement video set.
