Abstract
(EN)
The embodiments of the present application disclose a television system, a program signal processing method and apparatus, a device and a medium. The system comprises: at least two tuners, at least two demodulators in one-to-one correspondence with the at least two tuners, a main processor and a CI card module. The at least two tuners are respectively connected to the corresponding demodulators and are configured to respectively acquire radio frequency signals at different frequency points, and process the radio frequency signals to obtain at least two intermediate frequency signals. Each demodulator is configured to demodulate the received intermediate frequency signals to obtain TSs corresponding to the intermediate frequency signals. The main processor is configured to combine the received at least two TSs, to obtain one TS; the CI card module is configured to decrypt the received TS, and send the decrypted TS to the main processor, so that the main processor continues to process the decrypted TS.

Des modes de réalisation de la présente invention concernent un système de télévision, un procédé et un appareil de traitement de signal de programme, un dispositif et un support. Le système comprend : au moins deux syntoniseurs, au moins deux démodulateurs en correspondance biunivoque avec lesdits syntoniseurs, un processeur principal et un module de carte CI. Lesdits syntoniseurs sont respectivement connectés aux démodulateurs correspondants et sont configurés pour acquérir respectivement des signaux de radiofréquence à différents points de fréquence, et pour traiter les signaux de radiofréquence afin d'obtenir au moins deux signaux de fréquence intermédiaire. Chaque démodulateur est configuré pour démoduler les signaux de fréquence intermédiaire reçus pour obtenir des TS correspondant aux signaux de fréquence intermédiaire. Le processeur principal est configuré pour combiner les deux, ou plus, TS reçus, pour obtenir un TS ; le module de carte CI est configuré pour déchiffrer le TS reçu, et envoyer le TS déchiffré au processeur principal, de sorte que le processeur principal continue à traiter le TS déchiffré.
