摘要：
An audio input interface (122) receives a digital audio signal and identifies an audio bitstream which is optionally decrypted by a decryption unit (123), and decoded by an audio decoding unit (124). An audio digital to analog converter (126) converts the decoded audio bitstream to an analog audio signal which is optionally decrypted by an audio analog decryption unit (127) and output by an audio output interface (128) to an analog wireline device (100). A video input interface (142) receives a digital video signal and identifies a video bitstream which is optionally decrypted by a video digital decryption unit (143), and decoded by a video decoding unit (144). A video digital to analog converter (146) converts the decoded video bitstream to an analog video signal that is optionally decrypted by a video analog decryption unit (147) and output by a video output interface (148) to the analog wireline device (100).
