Abstract
(EN)
In a channel zapping though multiple channels, each channel select identifies a new packet stream channel and the video coding standard of the channel is identified. Based on the video coding standard an optimal input buffer delay is identified, a packet stream for the new channel delayed by the optimal input buffer delay, and decoded by a decoding process according to video coding standard. Optionally, based on the video coding standard an optimal decoding processing delay is identified and the decoding applies an associated processing delay.

(FR)
Dans un changement de canal sur de multiples canaux, chaque sélection de canal identifie un nouveau canal de flux de paquets et la norme de codage de vidéo du canal est identifiée. Sur la base de la norme de codage de vidéo, un retard de tampon d'entrée optimal est identifié, un flux de paquets pour le nouveau canal est retardé du retard de tampon d'entrée optimal, et est décodé par un traitement de décodage selon la norme de codage vidéo. Facultativement, sur la base de la norme de codage vidéo, un retard de traitement de décodage optimal est identifié et le décodage applique un retard de traitement associé.
