Title
(EN) BITRATE AND PIPELINE PRESERVATION FOR CONTENT PRESENTATION
(FR) MAINTIEN DE DÉBIT BINAIRE ET DE PIPELINE POUR LA PRÉSENTATION DE CONTENU
Abstract
(EN)
Systems and methods for optimizing a content change process are provided. In example embodiments, a digital receiver causes playback of a first piece of content. The digital receiver receives a selection of a new piece of content for playback during the playback of the first piece of content. In response to the receiving of the selection, the digital receiver maintains a bitrate used for playback of the first piece of content to initiate playback of the new piece of content.

La présente invention concerne des systèmes et des procédés pour optimiser un traitement de changement de contenu. Dans des modes de réalisation donnés à titre d'exemple, un récepteur numérique déclenche la lecture d'un premier élément de contenu. Le récepteur numérique reçoit une sélection d'un nouveau élément de contenu destiné à être lu pendant la lecture du premier élément de contenu. En réponse à la réception de la sélection, le récepteur numérique maintient le débit binaire utilisé pour la lecture du premier élément de contenu pour déclencher la lecture du nouvel élément de contenu.
