Abstract

Procesamiento de datos multimedia, y más particularmente, operaciones de procesamiento llevados a cabo antes de, o en conjuncion con, el procesamiento de compresion de datos. Un método para el procesamiento de datos multimedia incluye recibir cuadros de video entrelazados, obtener metadatos para los cuadros de video entrelazados, convertir los cuadros de video entrelazados en video progresivo mediante la utilizacion de por lo menos una porcion de los metadatos; y proveer el video progresivo y por lo menos una porcion de los metadatos a un codificador para su uso en la codificacion del video progresivo. El método puede también incluir generar informacion espacial e informacion bidireccional del movimiento para los cuadros de video entrelazados, y generar video progresivo sobre la base de los cuadros de video entrelazados mediante la utilizacion de la informacion espacial y bidireccional del movimiento.
