Abstract
SE PRESENTA UN SISTEMA QUE UTILIZA UN FORMATO DE DISCO OPTICO PARA REPRESENTAR VARIAS SEÑALES SINCRONIZADAS, POR EJEMPLO VERSIONES MULTIPLES DE IMAGENES EN MOVIMIENTO Y PISTAS DE SONIDO MULTIPLES QUE ESTA CONSTITUIDO DE UN DISCO OPTICO (23), PROCESADORES DE SEÑALES (67, 71), CIRCUITERIA DE BUFFER (53, 55, 57, 59) Y DISPOSITIVOS DE SALIDA DE AUDIO (91) Y DE VIDEO (94). TODAS LAS SEÑALES SE REPRESENTAN DIGITALMENTE, Y LOS BITS ESTAN DISPUESTOS EN BLOQUES DE DATOS. CADA BLOQUE DE DATOS PUEDE CONTENER UN NUMERO VARIABLE DE BITS PARA CADA SEÑAL, OSCILANDO DESDE NINGUNO HASTA MUCHOS (CON RELACION A LAS OTRAS SEÑALES). ESTO PERMITE QUE CADA SEÑAL SEA REPRESENTADA POR UNA CORRIENTE DE BITS DE VELOCIDAD VARIABLE, SIN QUE UNA SEÑAL CONSTRIÑA NECESARIAMENTE A LA OTRA EN LO QUE SE REFIERE A LA REPRESENTACION DE BITS. SE SUMINISTRAN BUFFERS MULTIPLES PARA ASEGURAR QUE HAYA UN NUMERO SUFICIENTE DE BITS DISPONIBLES PARA CADA SEÑAL SEGUN SE REQUIERA PARA LAS NECESIDADES INMEDIATAS. CUANDO CUALQUIER BUFFERESTA LLENO, SE DETIENE LA LECTURA DE LOS BLOQUES DE DATOS TEMPORALMENTE DE MANERA QUE NO SE PIERDAN LOS BITS.
