Abstract
PARA SER CAPAZ DE TRANSMITIR IMAGENES DE TELEVISION EN FORMATO DIGITAL SOBRE UN MEDIO QUE TENGA UN ANCHO DE BANDA LIMITADO, LA IMAGEN SUFRE ALGUNAS OPERACIONES DE CODIFICACION Y SE CONVIERTE EN UNA SERIE DE BLOQUES DE BITS DE TRANSMISION TRB SUB N DE LONGITUD VARIABLE (POR EJEMPLO DCT Y CODIFICACION DE LONGITUD VARIABLE). CADA BLOQUE DE BITS DE TRANSMISION ESTA DIVIDIDO EN UN BLOQUE PRINCIPAL H SUB N QUE COMPRENDE AL MENOS LAS PALABRAS DE CODIGO MAS IMPORTANTES Y UN BLOQUE AUXILIAR S SUB N QUE COMPRENDE LAS OTRAS PALABRAS DE CODIGO. LLEVANDO A CABO UNA OPERACION DE FORMATEO, UN GRUPO DE BLOQUES DE BITS DE TRANSMISION SE CONVIERTE EN UN BLOQUE DE BITS DE CANAL QUE CONSTA DE UN NUMERO DE BLOQUES DE BITS DE SUBCANAL SCB SUB N DE IGUAL LONGITUD. LOS BLOQUES PRINCIPALES SE ACOMODAN EN LAS PRIMERAS POSICIONES DE BIT DE LOS BLOQUES DE BITS DE SUB CANAL Y LOS BITS DE LOS BLOQUES AUXILIARES SE DISTRIBUYEN SOBRE LAS POSICIONES DE BITS RESTANTES (FIGURA 6E). DE ESTE MODO SE CONSIGUE QUE LA INFORMACIONMAS IMPORTANTE SEA SIEMPRE LOCALIZADA EN SITUACIONES FIJAS DE TAL FORMA QUE LA INFLUENCIA DE PERDIDAS DE SINCRONIZACION SE REDUZCA CONSIDERABLEMENTE.
