Video processing system for demultiplexing received compressed and non-compressed video signals and transmitting demultiplexed signals

A display apparatus, comprising:

• a video receiver configured to receive digital video signals from an external video signal source;
• a tuner configured to receive a digital broadcast signal;
• and
• a display configured to display a video,
• wherein:
• the display apparatus has at least a first display mode, a second display mode, and a third display mode;
• in the first display mode, the video receiver receives a first digital video signal encrypted by a first encryption scheme from the external video signal source, decrypts the received first digital video signal encrypted by the first encryption scheme, and the display (unit) displays a video based on the decrypted first digital video signal;
• in the second display mode, the video receiver receives the second digital video signal encrypted by a second encryption scheme from the external video signal source, decrypts the received second digital video signal encrypted by the second encryption scheme, and the display (unit) displays a video based on the decrypted second digital video signal;
• in the third display mode, the display displays a video based on the digital broadcast signal received by the tuner;
• and
• wherein the first digital video signal is an uncompressed digital video signal, and the second digital video signal is a compressed digital video signal.
