Abstract: There are disclosed various methods, apparatuses and computer program products for video encoding. The type of prediction used for a reference picture index may be signaled in the video bit-stream. The omission of motion vectors from the video bit-stream for a certain image element may be signaled; signaling may indicate to the decoder that motion vectors used in prediction are to be construed at the decoder. The construction of motion vectors may take place by using disparity information that has been obtained from depth information of the picture being used as a reference.

Abstract: A method comprising: requesting, by a client, an independently coded first representation of a video content component from a server; receiving a bitstream and playing a first set of data units of the independently coded first representation; and requesting a second set of data units of a second representation, said second set of data units being dependently coded on one or more requested or buffered data units of the first set, said second set of data units being temporally partitioned into two parts where a base part is decodable without an enhancement part and an enhancement part may not be decodable without the base part.

Abstract: There is provided a method comprising encoding an uncompressed constituent frame into a first encoded picture, said encoding also resulting into a reconstructed first picture and said constituent frame having an effective picture area within the first reconstructed picture, performing either of the following as a part of said encoding: inserting at least one sample value outside the effective picture area to form a boundary extension for the constituent frame in the reconstructed first picture; or saturating or wrapping over sample locations outside the effective picture area to be within the effective picture area. There is also provided a method comprising receiving an encoded picture, decoding the encoded picture to form a reconstructed constituent frame of the picture having an effective picture area; and performing either of the following: filling an area outside the effective picture area to produce a padded reference picture, wherein the filled area forms a boundary extension; or determining that when referring to sample locations outside the effective picture area in decoding, said sample locations are saturated or wrapped over to be within the effective picture area.

Abstract: "método de codificação/decodificação de um sinal de vídeo representando uma seqüência de imagens, e, codificador/decodificador de vídeo". método para codificar um sinal de vídeo representando uma sequência de imagens, o método compreendendo receber a imagem atual para codificar, formando uma predição temporal da imagem atual de uma imagem de referência default para a imagem atual, comparando a imagem de referência default com ao menos uma outra imagem de referência, calculando a medida de similaridade entre a imagem de referência default e cada outra imagem de referência e, se a medida de similaridade encontra um critério pré-determinado, produzir um indicador identificando a outra imagem de referência.
