Patent

CA 2284672

Random access to arbitrary fields of a video segment compressed using both interframe and intraframe techniques is enhanced by adding state information to the bitstream prior to each intraframe compressed image to allow each intraframe compressed image to be randomly accessed, by generating a field index that maps each temporal field to the offset in the compressed bitstream of the data used to decode the field, and by playing back segments using two or more alternatingly used decoders. The cut density may be improved by eliminating from the bitstream applied to each decoder any data corresponding to bidirectionally compressed images that would otherwise be used by the decoder to generate fields prior to the desired field.

On améliore l'accès sélectif à des champs arbitraires d'un segment vidéo comprimé au moyen de techniques à la fois inter-images et intra-images mettant en application l'apport d'une information d'état au train binaire préalablement à chaque image présentant une compression intra-image afin de pouvoir accéder à cette image de façon sélective, la génération d'un indice de champ établissant la cartographie de chaque champ temporel par rapport au décalage du train binaire comprimé de données utilisées afin de décoder le champ, ainsi que la reproduction de segments en utilisant alternativement deux ou plusieurs décodeurs. On peut augmenter la densité de coupure en éliminant du train binaire appliqué à chaque décodeur toutes données correspondant à des images comprimées dans les deux sens qui seraient sinon utilisées par le décodeur afin de générer des champs préalablement au champ souhaité.
