Abstract: A receiver includes a line store progressive scan processor and a frame store progressive scan processor for doubling the line rate of a video input signal for display. The video input signal includes an identifying signal signifying whether the fields that are derived from a common scene. The identifying signal is detected and used to control a switch for selectively coupling the output of the processors to a display such that frame store processed signals are displayed for fields derived from exactly the same scene and line store processed signals are displayed for "mixed" fields (i.e., fields from different frames or frames containing motion).

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.

Abstract: A wide aspect ratio television system includes memories (40,42,44) for storing and recovering a video input signal in response to read and write clock pulses, respectively. Write clock pulses are deleted (410, Figure 4) to compress edge regions of a wide aspect ratio input signal and read clock pulses are deleted (Figure 8) to restore the signal to its original aspect ratio. The pattern of deleted pulses is preferably altered (404) on a line-by-line basis to reduce visible artifacts of signal decimation. In dual mode receivers which may include provisions for controlling edge blanking or effecting edge interpolation, the pattern of deleted clock pulses may be selected as a function of the type of received signals.

Abstract: A wide-angle television system, such as one having 2:1 or 5:3 aspect ratios, transmits end portions that exceed the limits of a conventional 4:3 aspect ratio picture in regions that are normally hidden from view in a conventional receiver. Thus the system is compatible with such a receiver. These regions can comprise the overscan region, blanking intervals, high frequency portions of a chroma signal, etc. Time compression of the end portions can also be used. At a wide-angle receiver, inverse processing is used to reassemble a wide-angle picture.

Abstract: A color television camera includes imagers which produce signals representative of various colors of a scene. The signals are multiplexed to an analog-to-digital converter (ADC) for conversion to sequential digital video form for processing by a single-channel digital processor. In order to avoid loss of resolution, and to take full advantage of the speed of operation of the ADC, the imagers are clocked mutually out-of-phase so as to sequentially provide imager signals at a rate related to the multiplexer rate.

Abstract: An apparatus for correcting errors in color signal transitions includes a signal scaling device and a signal mixing device. A wide bandwidth luminance signal is applied to the signal scaling device which develops a limiting signal for a particular narrow bandwidth color difference or primary color signal. This limiting signal is mixed with its associated color difference or primary color signal by the signal mixing device. The output of the signal mixing device is a color difference or primary color signal that has amplitude values less than or equal to the amplitude values of the limit signal.
