Efficient representation and coding of omni-directional video using MPEG-4

This paper presents an efficient approach for representation and coding of omni-directional video that applies exclusively available MPEG-4 technology, i.e. the combination of 3D Mesh Objects with video textures. This allows application of efficient spherical projections such as equal-area projections or a faceted representation of the image information. Any 3D MPEG-4 player can be used to render and display the omni-directional video interactively. This simple but universal approach enables full competition at the encoder side while providing full interoperability at the decoder side
