Abstract
An improved transmission arrangement for a color television signal includes a time-division multiplexing apparatus for alternately presenting for transmission through a single channel baseband signals defining the chrominance information of the television signal. In order to provide improved resolution, a store is coupled to the signal source for storing at a writing rate a first of the baseband components during the time at which it is generated. A read generator is coupled to the store for reading the stored baseband component at a higher data rate than that at which it was generated. The baseband component is transmitted through the single channel at the higher data rate.
Claims10
An improved multichannel television signal record system, in which luminance information is recorded separately from chrominance information, and wherein said chrominance information comprises first and second signal components, comprising:
- a first channel for recording luminance signals;
- a second channel for recording said chrominance information, said second channel being subject to nonlinearities which may cause cross-modulation between said first and second signal components of said chrominance information when said first and second signal components are processed concurrently;
- wherein the improvement comprises:
- switching means coupled to said second channel for alternately coupling said first and second signal components of said chrominance information for recording in said second channel whereby said first and second signal components are processed alternately rather than concurrently thereby eliminating said cross-modulation.
