A device for encoding and a device for decoding a picture, respectively, and corresponding methods relating to the field of picture coding are provided. The devices are respectively configured to partition the picture into one or more slices, each slice comprising one or more tiles, and one or more slices holding coded picture data. Further, the devices are configured to encode the one or more slices holding coded picture data, thereby improving coding and decoding of pictures with uncoded buffer space.

Devices and methods for coding a picture by partitioning it into slices comprising tiles

An apparatus, a method, and a computer program performs image coding with selective loop-filtering. That is, the loop-filters which operate on samples across discontinuous face boundaries are capable of being disabled. The loop-filter operation may be deferred until all samples across a face boundary are known. Then, the loop-filter can use the correct samples according to the 3D arrangement. This may be implemented on the coding block level or at a higher level.

Apparatus and method for picture coding with selective loop-filtering

A system for encoding and decoding a video coding block of a multi-view video signal is provided. A decoder is configured to decode a texture-depth video coding block (t, d) of a first texture frame and a first depth map associated with a first view for providing a decoded texture-depth video coding block (t, d) and the first depth map. A synthesized predicted texture-depth video coding block (t, d) of a view synthesis texture frame and a view synthesis depth map associated with a second view is generated. An inpainted synthesized predicted texture-depth video coding block is generated. Based on the impainted predicted texture-depth video block, the decoder reconstructs a texture-depth video coding block (t, d) of a second texture frame and a second depth map associated with the second view. An encoder is configured to encode the texture-depth video coding block in a manner that complements the decoding provided by the decoder.

A method for encoding a video signal includes generating an extension region of a first face of a reference frame, where the extension region includes a plurality of extension samples, and a sample value of each extension sample is based on a sample value of a sample of a second face of the reference frame, determining a use of an extension region, providing, based on the use, picture level extension usage information based on the extension region, and encoding the picture level extension usage information into an encoded video signal.
