Title (EN) METHOD AND APPARATUS FOR SWITCHING DIGITAL TELEVISION CHANNELS
(FR) PROCÉDÉ ET APPAREIL DE COMMUTATION DE CANAUX DE TÉLÉVISION NUMÉRIQUE
(ZH) 实现数字电视换台的方法和装置
Abstract:
(EN) A method for switching digital television channels, comprising: receiving a user-input channel-switching instruction for switching to a target program; querying a target control word of the target program in a control word data table stored in a set-top box; and configuring a descrambler according to the target control word when the target control word is found so as to descramble a target program data stream pushed by a service front end to the set-top box and to carry out playback.
(FR) L'invention concerne un procédé de commutation de canaux de télévision numérique, comprenant les étapes consistant à : recevoir une instruction de commutation de canal d'entrée utilisateur pour la commutation vers un programme cible ; demander un mot de commande cible du programme cible dans une table de données de mots de commande stockée dans un boîtier décodeur ; et configurer un désembrouilleur conformément au mot de commande cible lorsque le mot de commande cible est trouvé, de manière à désembrouiller un flux de données de programme cible poussé par un frontal de service vers le boîtier décodeur et effectuer une lecture.
(ZH) 一种数字电视换台的方法,包括:接收用户输入的切换至目标节目的换台指令;在机顶盒存储的控制字数据表中查询所述目标节目的目标控制字;以及当查询到所述目标控制字时,根据所述目标控制字设置解扰器,以解扰服务前端推送至机顶盒的目标节目数据流并进行播放。
