Start code for signalling bits |
摘要 |
In an extended television signal having signalling bits for conveying control information to control an extended decoder, the signalling bits include a start code and data bits. The start code's main lobe of spectral energy resides in the lower spectral area of a baseband television signal below 2 MHz and preferably below 1.7 MHz. The start code is preferably (almost) DC-free, and the start code has good aperiodic correlation properties and a predetermined minimum bit Hamming distance to the data bits when shifted in the direction of the data bits following the start code.
