Definitions

  • the video header is common information for recording the video data, and each video unit is divided by a sync header.
  • a "relative time stamp” information is set for each video unit in each video header to record each The relative time difference of the video unit.
  • the "absolute timestamp” information is taken out from the channel header to determine the initial playing time of the channel data; then the "relative timestamp” information of each video unit is taken from the video header of the channel, from the channel's The “relative timestamp” information of each audio unit is taken out from the audio header, and the “relative timestamp” of each video unit is added to the "absolute timestamp” according to the above algorithm to determine the initial playback of each video unit.

Abstract

L'invention concerne un procédé de lecture synchrone de données audio et vidéo en diffusion multimédia mobile. Un champ 'horodateur absolu' est défini dans une en-tête de canal pour indiquer l'heure de démarrage de lecture des données de canal. Des données audio et vidéo sont divisées en une pluralité d'unités audio et d'unités vidéo respectives. Un champ horodateur relatif' est défini pour chaque unité audio et vidéo dans chaque en-tête audio et vidéo pour enregistrer l'écart relatif de l'heure de démarrage de lecture de chaque unité audio et vidéo suivant l'écart relatif entre l'heure de démarrage de lecture de chaque unité audio et vidéo et l'heure de démarrage de lecture de l'ensemble des données de canal. L'heure réelle de démarrage de lecture de chaque unité audio et vidéo est la somme de 'l'horodateur absolu' et de 'l'horodateur relatif' de chaque unité audio et vidéo. Le terminal calcule le temps de lecture de chaque unité audio et vidéo après réception des données, de façon à réaliser une lecture synchrone des données audio et vidéo.
