(EN) RECORDING/REPRODUCING SYSTEM

Abstract
(EN)
An I-picture detecting section (15) of a recording/reproducing system (RRS1) generates and outputs a control signal CS representing the bit position of a TS packet including a part of an I picture from an output transport stream DETS from a descrambler (13). A TS header processing section (16) specifies the TS header added to the payload of the I picture from the transport stream TS on the basis of the control signal CS and changes the reservation bit in the TS header from 0 to 1. A storage unit (SU1) refers to the reservation bit of the TS header in high-speed reproduction, selects only the transport packet of the I picture necessary for the high-speed reproduction, creates a transport stream PRTS', and sends it to a decoding unit (DU1). Thus simple high-speed reproduction is realized.

Une section de détection d'images de type I (15) d'un système d'enregistrement/lecture (RRS1) génère et délivre en sortie un signal de commande CS représentant la position des bits d'un paquet TS incluant une partie d'une image I issue d'un train de données de transport DETS en sortie d'un désembrouilleur (13). Une section de traitement des en-têtes TS (16) spécifie l'en-tête TS ajoutée à la charge utile de l'image de type I issue du train de données de transport TS sur la base du signal de commande CS et modifie le bit de réservation dans l'en-tête TS de 0 à 1. Une unité de stockage (SU1) se réfère au bit de réservation de l'en-tête TS en lecture à haute vitesse, sélectionne uniquement le paquet de transport de l'image de type I nécessaire à la lecture à haute vitesse, crée un train de données de transport PRTS' et transmet ce dernier à une unité de décodage (DU1). Il est ainsi possible d'effectuer simplement une lecture à grande vitesse.
