Conditional-access-module for digital television receiver, has conversion device to convert decoded signal content into broadcasting signal, and analog television signal interface to couple broadcasting signal with analog input of receiver

摘要

The module (100) has a recognition device for contents of multiplexed data streams. A decoding device decodes digital coded contents, and a red, green, blue conversion device converts the decoded signal content into an analog color broadcasting signal. An analog television signal interface couples the broadcasting signal with an analog input of a digital television receiver. A black image generator generates digital coded black images.
