VIDEO PROCESSING SYSTEM FOR DEMULTIPLEXING RECEIVED COMPRESSED AND NON-COMPRESSED VIDEO SIGNALS AND TRANSMITTING DEMULTIPLEXED SIGNALS

摘要

The present invention is intended to permit both real-time display of a picture represented by a non-compressed video signal on a television and display of a picture represented by a compressed video signal at any desired time by simultaneously transmitting the compressed video signal and non-compressed video signal via one interface. An STB packetizes a compressed video signal, and multiplexes the compressed video signal and a blanking signal combined with a non-compressed video signal. Thus, both the video signals are transmitted simultaneously. A picture represented by the non-compressed video signal is displayed on a television in real time. The compressed video signal is stored in a storage medium incorporated in the television, read at any user's desired time, and decoded so that a picture represented by the compressed video signal can be viewed at the user's desired time.

主权项

1. A display device, comprising:
an input terminal which includes a data line inputting a video signal and a clock line inputting a clock signal of the video signal; a tuner unit which inputs a digital broadcasting signal; and a display unit which displays the input video signal, wherein the display unit is configured to display: a first display which displays the video signal input to the data line of the input terminal by using the clock signal input to the clock line of the input terminal; a second display which displays the video signal input to the data line of the input terminal by using the clock signal multiplexed to the video signal input to the data line of the input terminal; and a third display which displays the video signal included in the digital broadcasting signal input with the tuner unit.
