Abstract: Method and apparatus for producing a frozen television picture are disclosed. Successive fields of picture information are generated by an interpolator which is responsive to a video input signal. These successive fields are applied to the input of a first field store device. The video input signal is applied to the input of a second field store device so that the successive fields of the video input signal correspond in time to the successive fields generated by the interpolator. Lines from the respective field store devices are sequenced repetitively to form a video signal representing the frozen television picture. The interpolator generates fields which, when displayed with corresponding fields of the video input signal, minimizes motion-induced artifacts without unduly degrading vertical resolution.

Abstract: A television arrangement generates signals from independent pairs of adjacent lines. The signals are separately summed and differenced to produce S and DELTA signals. The S signal is representative of the luminance of a scan between the original scans, and the DELTA represents vertical resolution. The signals are transmitted to a monitor for generating a high-vertical-resolution picture. Where the display is a color TV receiver, the DELTA signal may be buried within the chroma channel by frequency interleaving with the DELTA signal occuring only in locations representing high-frequency vertical information. The buried DELTA signal is invisible on a conventional receiver. Other independent data may be coupled through the chroma channel by frequency interleaving.

Abstract: A matrix for digital video signals separates each coefficient into a binary part and a remainder. The binary part can be implemented very simply by a hardwired right shift. The remainder can be implemented using a ROM. Less ROM memory space is required than for implementing the entire coefficient in a ROM.

Abstract: A video display system for displaying a wide screen image having an aspect ratio, such as 5:3, greater than the standard, such as 4:3, aspect ratio of the images represented by conventional television video signals, is arranged for displaying such an image of standard aspect ratio without changing the width of the normal wide aspect raster of the display system. To this end the display system includes a signal processor which, in response to a video signal representative of a standard aspect ratio image, produces, for driving the wide aspect ratio display, a processed video signal the line periods of which each include not only the line synchronizing interval and active video interval but also a delay interval ('PAUSE') the effect of which is to determine the position of the displayed standard aspect ratio image within the width of the wide aspect ratio raster.

Abstract: A multichannel sampled system uses a single set of steering bits to reconstruct deleted samples from all channels. The steering bits can be derived from the channel having the greatest bandwidth or amplitude, or by majority voting logic operating on steering bits from all channels.

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.
