(EN) METHOD AND SYSTEM FOR VFC MEMORY MANAGEMENT
(FR) PROCEDE ET SYSTEME DE GESTION DE MEMOIRES VFC
Abrégé
(EN) A method for managing vertical format converter ('VFC') line memories (62) includes writing a number of first input video lines into the VFC line memories (62), writing an additional video line into the VFC line memories (62), and reading respective pixels of the first input video lines and the additional input video line from the VFC line memories (62) in parallel. The reading of respective pixels is commenced prior to completion of the writing of the additional video line. A digital video receiving system (10) includes a somewhat similarly configured video processor (32).
(FR) Cette invention se rapporte à un procédé servant à gérer des mémoires de lignes à convertisseur en format vertical (VFC) (62) et consistant à cet effet à inscrire un certain nombre de premières lignes vidéo d'entrée dans les mémoires de lignes VFC (62), à inscrire une ligne vidéo supplémentaire dans les mémoires de lignes VFC (62) et à lire les pixels respectifs des premières lignes vidéo d'entrée et de la ligne vidéo d'entrée supplémentaire dans les mémoires de lignes VFC (62) en parallèle. La lecture des pixels respectifs commence avant la fin de l'inscription de la ligne vidéo supplémentaire. Un système récepteur vidéo numérique (10) comprend un processeur vidéo de configuration assez similaire (32).
