Abstract

Se efectua la codificacion por compresion de viseo solo intratrama de todos los cuadros sucesivos de video, de la manera en que se efectua la codificacionpor compresion de video intratrama en los cuadros de fondo I en la forma MPEG-2 y se identificacada cuadro en los encabezamientos de imagen como de compresionde video intratrama, de manera similar a como se efectua en el caso de los cuadros de fondo I en la norma MPEG-2. El codificador para hacer ésto es más simpleque el que se usa paracodifi car los cuadros P y los cuadros B como así también los cuadros I, pues no hay necesidad de contar con circuitos de estimacion demovimiento. Mediante el uso de tal codificador en una cámara de video digital portátil se reduce el consumo deenergía de la batería y permite reducir el pesoy tamano de la cámara de video portátil. La compresion de video solo intratrama facilita la edicion de video. En muchos sistemas en los que se efectua laedicion de video ya hay disponibles undecodificador MPEG-2, de modo que no requiere ningun costo adicional para que un decodificador decodifique la corrientede transporte de cuadros I sin cuadros P o B intermedios. Si no hay ya disponible un decodificador MPEG-2 en un sistema, proveerloimplica un costo razon able,pues la cantidad de hardware de un decodificador MPEG-2 es considerablemente menor que la de un codificador MPEG-2.
