Abstract

La présente invention se rapporte au domaine du traitement vidéo. Elle a trait à un procédé destiné au stockage et à la lecture d'informations supplémentaires dans un flux de code vidéo ainsi qu'à un dispositif associé. Selon la présente invention, des informations supplémentaires sont ajoutées à un flux de code vidéo sous la forme d'un type de trame spécial. Un en-tête de trame de cette trame est obtenu grâce à la modification du type et de la longueur d'un en-tête de trame d'une image vidéo existante dans le flux de code vidéo, les informations supplémentaires qui changent au fil du temps sont enregistrées dans un flux de code vidéo sous surveillance, et la compatibilité avec les lecteurs vidéo existants est assurée à bas prix. La trame d'informations supplémentaires est écrite derrière une image I correspondant aux informations supplémentaires, ce qui facilite en outre la recherche, la récupération et le décodage. Au cours de la lecture des données vidéo enregistrées, la lecture de piste sur une carte électronique s'avère très pratique pendant la lecture audio et vidéo, et les changements en temps réel concernant le volant, le compteur de vitesse et l'accélération triaxiale s'affichent pendant la lecture.
