Title (EN) METHOD AND DEVICE FOR PLAYING BACK TV PROGRAM
(FR) PROCÉDÉ ET DISPOSITIF DE LECTURE D'UNE ÉMISSION DE TÉLÉVISION
(ZH) 电视节目的播放方法及装置
Abstract:
(EN) A method for playing back a TV program: when a playback instruction for a program to be played back is detected, obtaining, from a server, a transmission stream corresponding to the program to be played back, and obtaining a designated conditional access module (CAM) identifier of the program to be played back; comparing the designated conditional access module identifier with a pre-saved conditional access module identifier corresponding to a conditional access module installed on a TV terminal; when the designated conditional access module identifier matches the pre-saved conditional access module identifier, transmitting the transmission stream to the conditional access module, and playing back the program on the basis of the transmission stream decoded by the conditional access module. Further disclosed is a device for playing back a TV program. The present invention reduces the costs for a TV terminal to playback a TV program.
(FR) L'invention concerne un procédé de lecture d'une émission de télévision comme suit : lorsqu'une instruction de lecture pour une émission à lire est détectée, obtenir, auprès d'un serveur, un flux de transmission correspondant à l'émission à lire, et obtenir un identifiant de module d'accès conditionnel (CAM) désigné de l'émission à lire ; comparer l'identifiant de module d'accès conditionnel désigné à un identifiant de module d'accès conditionnel préenregistré correspondant à un module d'accès conditionnel installé sur un terminal de télévision ; lorsque l'identifiant de module d'accès conditionnel désigné correspond à l'identifiant de module d'accès conditionnel préenregistré, transmettre le flux de transmission au module d'accès conditionnel, et lire l'émission selon le flux de transmission décodé par le module d'accès conditionnel. L'invention concerne aussi un dispositif de lecture d'une émission de télévision. La présente invention réduit les coûts de lecture d'une émission de télévision d'un terminal de télévision.
(ZH) 一种电视节目的播放方法,在检测到待播放节目的播放指令时,获取服务器发送的待播放节目对应的传输流,以及获取所述待播放节目的指定视密卡标识;将所述指定视密卡标识与电视终端安装的视密卡对应的预存视密卡标识进行比对;在所述指定视密卡标识与所述预存视密卡标识匹配时,将所述传输流传输至所述视密卡中,并基于所述视密卡解密后的传输流播放节目。还公开了一种电视节目的播放装置。降低了电视终端播放电视节目所消耗的成本。
