ABSTRACT:
Digital television broadcast signals are received and AV signals are reproduced in a common apparatus. A digital television signal is received and is separated into a compressed first video signal, a compressed first audio signal, and first copyright protection information. An AV signal is reproduced from a recording medium and is separated into a second compressed video signal, a second compressed audio signal, and second copyright protection information. The first signals and information are selected when a received operation command is a command to select the digital television broadcast channel, and the second signals and information are selected when the received operation command is a command to reproduce data. The selected signals and information are decoded to generate a decoded video signal, a decoded audio signal, and a copyright protection signal, and the copyright protection signal is added to the decoded signals to limit copying.
