Title
(EN) METHOD AND DEVICE FOR ENCODING SEAMLESS-CONNECTION OF TELECINE-CONVERTED VIDEO DATA
(FR) PROCEDE ET DISPOSITIF SERVANT A CODER UNE CONNEXION TRANSPARENTE DE DONNEES VIDEO CONVERTIES EN TELECINEMA
Abstract
(EN)
A converting/encoding device which naturally reproduces pictures even when the device arbitrarily connects a plurality of encoded signals to each other and reproduces the signals. A recording medium (M) used for the device is also disclosed. The device is provided with storage means (304 and 306) which store a plurality of fields of video signals, a selecting means (314) which selects one of the outputs of the storage means (304 and 306), a comparing means which compares the fields of the same parity with each other, a detecting means which detects a repeated redundant field based on the output of the result of the comparing means, a control means (322) which controls the selecting means (312) according to the result of detection of a redundant field and outputs an intermediate signal (RT8) from which the redundant field is removed, a flag generating means (312 and 322) which generate a flag related to the redundant field based on the result of detection of a redundant field, and an inhibiting means which inhibits the removal of the redundant field by holding the outputs of the control means (322) and flag generating means (312 and 322) at prescribed values. When a plurality of logical recording sections are provided on the same recording medium, the removal of the redundant field is inhibited at the first and last parts of each recording section.

L'invention porte sur un dispositif de conversion-codage reproduisant naturellement des images même lorsque ledit dispositif connecte arbitrairement une pluralité de signaux codés l'un à l'autre et reproduit ces signaux. L'invention concerne également un support d'enregistrement (M) utilisé avec ledit dispositif. Ce dispositif comprend: des mémoires (304 et 306) qui stockent une pluralité de zones de signaux vidéo; un organe de sélection (314) qui choisit l'une des sorties des mémoires (304 et 306); un organe de comparaison qui compare les zones de même parité l'une avec l'autre; un capteur qui détecte une zone redondante répétée basée sur le résultat de sortie de l'organe de comparaison; un organe de commande (322) qui commande l'organe de sélection (312) en fonction du résultat de détection d'une zone redondante, et qui sort un signal intermédiaire (RT8) à partir duquel la zone redondante est éliminée; des générateurs de marque (312 et 322) qui génèrent une marque liée à la zone redondante basée sur le résultat de détection d'une zone redondante; et un organe inhibiteur qui inhibe la suppression de la zone redondante en retenant les sorties de l'organe de commande (322) et des générateurs de marque (312 et 322) en fonction de valeurs déterminées. Lorsqu'une pluralité de sections d'enregistrement logiques coexistent sur le même support d'enregistrement, la suppression de la zone redondante est inhibée pour la première et la dernière partie de chaque section d'enregistrement.
