Title
(EN) REAL-TIME HIGH RESOLUTION VIDEO CAPTURE SYSTEM
(FR) SYSTEME D'ACQUISITION VIDEO HAUTE RESOLUTION EN TEMPS REEL
Abstract
(EN)
A system for real-time capture and playback of high resolution compressed and uncompressed digital video data received upon a JPEG video board (10) over an input line (D1). This input is converted into YUV, and may be scaled and adjusted for color, contrast, hue and saturation. A bus interface (16) is in communication with the video input to provide a high resolution digital video data stream. A transient memory (20) communicates with the interface (16) over a first data path (11), and a digital storage medium (31, 35, 36, 40) communicates with the transient memory over a second data path (12), where the first and second data paths are configured to permit real-time storage of the data stream under microprocessor control.

Système d'acquisition et de reproduction en temps réel de données vidéo numériques comprimées et décomprimées, à haute résolution, reçues sur une carte vidéo JPEG (10) par une ligne d'entrée (D1). Ce signal d'entrée est converti en signal de luminance/chrominance YUV et peut être mis à l'échelle et réglé par rapport à la couleur, au contraste, à la teinte et à la saturation. Une interface de bus (16) communique avec le signal d'entrée vidéo pour produire un flux de données vidéo numériques à haute résolution. Une mémoire non résidente (20) communique avec l'interface (16) sur un premier chemin de données (11) et un support d'informations numérique (31, 35, 36, 40) communique avec cette mémoire non résidente sur un deuxième chemin de données (12), les premier et deuxième chemins de données étant configurés de façon à permettre le stockage en temps réel du flux de données sous la commande du microprocesseur.
