| Especificación de conformidad para codificación de vídeo avanzada H.264 |
 |
La presente Recomendación especifica pruebas diseñadas para verificar si los trenes de bits y los decodificadores sometidos a las mismas cumplen los requisitos normativos especificados en la Rec. UIT-T H.264 | ISO/CEI 14496-10:
• Un codificador será conforme a la Rec. UIT-T H.264 | ISO/CEI 14496-10 si los trenes de bits que genera son trenes de bits conformes.
• Un decodificador será conforme a un perfil y nivel determinados de la Rec. UIT-T H.264 si puede decodificar satisfactoriamente todos los trenes de bits que se atengan a las restricciones especificadas en la Rec. UIT-T H.264 | ISO/CEI 14496-10.Las pruebas especificadas en esta Recomendación proporcionan los métodos con los que comprobar (de manera no exhaustiva) si los codificadores y decodificadores cumplen esos requisitos.Este texto, idéntico al de ISO/CEI, se ha desarrollado conjuntamente en el marco de un equipo mixto sobre vídeo (JVT, joint video team) y se ha presentado a ISO/CEI JTC 1/SC 29/WG 11 (MPEG) como ISO/CEI 14496-4:2002/enmienda 6 (2005 S) e ISO/CEI 14496-4:2004/enmienda 9.El corrigendum 1 a la Rec. UIT-T H.264.1 (09/2005), que ha sido integrado en esta edición de la Rec. UIT-T H.264.1, mejora la alineación con el texto técnico gemelo de ISO/CEI, elimina algunos errores y añade pruebas para algunas de las características requeridas que no estaban sometidas a prueba en la versión anterior.Los trenes de bits conformes a la Rec. UIT-T H.264.1 pueden encontrarse como fichero electrónico a la presente Recomendación. |
