Embodiment Construction
[0030] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] Step 1: Before video adaptive transmission, the server side prepares resources for multi-view bit streams, such as figure 1 The system block diagram of the server, the specific embodiment of the present invention adopts 3 cameras arranged in a circle with the same baseline distance for video capture, and adopts the 3D-HEVC standard to independently and symmetrically encode the captured video streams, and each viewpoint is encoded into L bitrate playback versions (v 1 ,v 2 ,...,v L ). Each viewpoint video is cut into N video slices at the same time interval (8 seconds). Packing and synthesis of two bitstreams: two-view plus depth (2VD) and three-view plus depth (3VD).
[0032] Step 2: Media description file generation. According to th...
