Abstract

POR LO GENERAL, ESTA REVELACIÓN DESCRIBE TÉCNICAS PARA LA CODIFICACIÓN DE BLOQUES DE VIDEO POR EL USO DE UN PROCESO DE CONVERSIÓN DE ESPACIO DE COLOR. UN CODIFICADOR DE VIDEO, COMO UN CODIFICADOR DE VIDEO O UN DECODIFICADOR DE VIDEO, PUEDE DETERMINAR UN MODO DE CODIFICACIÓN UTILIZADO PARA CODIFICAR LOS DATOS DE VIDEO. EL MODO DE CODIFICACIÓN PUEDE SER UNO CON PÉRDIDAS O UNO SIN PÉRDIDAS. EL CODIFICADOR DE VIDEO PUEDE DETERMINAR UN PROCESO DE TRANSFORMACIÓN DE ESPACIO DE COLOR QUE DEPENDE DEL MODO DE CODIFICACIÓN UTILIZADO PARA CODIFICAR LOS DATOS DE VIDEO. EL CODIFICADOR DE VIDEO PUEDE APLICAR EL PROCESO DE TRANSFORMACIÓN DE ESPACIO DE COLOR EN LA CODIFICACIÓN DE LOS DATOS DE VIDEO. EN LA DECODIFICACIÓN DE LOS DATOS DE VIDEO, INDEPENDIENTEMENTE DE SI EL MODO DE CODIFICACIÓN ES UNO CON PÉRDIDAS O UNO SIN PÉRDIDAS, EL CODIFICADOR DE VIDEO PUEDE APLICAR EL MISMO PROCESO DE TRANSFORMACIÓN INVERSA DE ESPACIO DE COLOR EN UN BUCLE DE DECODIFICACIÓN DEL PROCESO DE CODIFICACIÓN
