Title (EN) MULTIMEDIA INFORMATION COMMUNICATION DEVICE AND ITS METHOD
(FR) DISPOSITIF DE COMMUNICATION D'INFORMATIONS MULTIMEDIA ET PROCEDE
Abstract:
(EN) In a media separating unit, a data separating section separates a video packet and an audio packet, a CRC computing section carries out again the same computation carried out by the encoding side through a CRC code separating section and outputs the result of the computation to an error information adding section. The error information adding section compares the result of the computation with a CRC code added to the video packet to check whether they agree with each other. After the check, the error information adding section adds the result of the check as error information to the video packet and outputs the video packet as a new video packet to a video decoder through a buffer.
(FR) L'invention porte sur une unité de séparation de média dans laquelle une section de séparation de données sépare un paquet vidéo d'un paquet audio ; une section de calcul CRC effectue le même calcul réalisé par le côté de codage par l'intermédiaire d'une section de séparation de code CRC et envoie le résultat du calcul à une section d'addition d'informations d'erreurs. La section d'addition d'informations d'erreurs compare le résultat du calcul avec un code CRC ajouté au paquet vidéo afin de vérifier s'il y concordance entre les calculs. Après vérification, la section d'addition d'informations d'erreurs ajoute le résultat de la vérification sous forme d'informations d'erreurs au paquet vidéo et envoie le paquet vidéo sous forme d'un nouveau paquet vidéo à un décodeur vidéo par l'intermédiaire d'un tampon.
