TELEVISIONSTRANSMISSIONSSYSTEM |
摘要 |
A component television signal is transmitted as a sequence of television frames with each frame having a plurality of television lines substantially all of which have first and second time multiplexed portions. The first portion (DB) forms the data burst and conveys sound/data information in digital form at a given bit rate while the second portion of each line outside the vertical blanking intervals (VBI) conveys vision information (U/V, Y). The second portion of at least some of the lines in the verical blanking intervals (VBI) convey additional information in digital form at a higher bit rate than the given bit rate and which may be twice the given bit rate. This additional information can be the digital channel information for a digitally assisted television signal. |
