Patent

CA 2451997

The invention concerns a method (200) and system (10) for recording onto a storage medium (26) a video segment. The method includes the steps of : receiving the video segment (210) in which the video segment contains at least one predictive picture; and selectively converting the at least one predictive picture into an intra picture thereby replacing the at least one predictive picture with the intra picture. In one arrangement, the video segment can contain at least one introductory predictive picture, and the converting step can further include selectively decoding a predetermined number of the introductory predictive pictures to obtain a properly decoded predictive picture (212). Additionally, the video segment can contain at least one subsequent predictive picture and the converting step can further include selectively decoding the subsequent predictive pictures (214) and selectively re-encoding into intra pictures the subsequent predictive pictures, the introductory predictive pictures or a combination thereof (216).

L'invention concerne un procédé (200) et un système (10) servant à enregistrer un segment vidéo sur un support (26) de stockage. Le procédé comporte les étapes consistant à : recevoir le segment (210) vidéo, celui-ci contenant au moins une image prédictive ; et convertir sélectivement la ou les image(s) prédictive(s) en une image intra, de manière à remplacer la ou les image(s) prédictive(s) par l'image intra. Dans une forme de réalisation, le segment vidéo peut contenir au moins une image prédictive d'introduction, et l'étape de conversion peut en outre comprendre sélectivement le décodage d'un nombre prédéterminé des images prédictives d'introduction en vue d'obtenir une image (212) prédictive dûment décodée. De plus, le segment vidéo peut contenir au moins une image prédictive ultérieure, et l'étape de conversion peut comprendre en outre le décodage des images (214) prédictives ultérieures et le recodage sélectif en images intra des images prédictives ultérieures, des images prédictives d'introduction ou d'une combinaison de celles-ci (216).
