A video display system comprises: a video display; first and second signal processors for cropping first and second video signals representative of first and second pictures; a circuit for generating a side-by-side display format of the pictures on the video display; and, a panning contr
5420643 Chrominance processing system for compressing and expanding video data May 30, 1995
A circuit for compressing and expanding video color component data comprises a FIFO line memory and a delay circuit. A timing circuit generates control signals for writing data into the line memory and for reading data from the line memory to compress and expand the data. The delay c
5351135 Managing letterbox signals with logos September 27, 1994
A video display control system comprises: a video display having a wide format display ratio; a letterbox detector for sampling video information in pictures represented by input video signals having a letterbox format and generating a control signal for enlarging the pictures for su
5351087 Two stage interpolation system September 27, 1994
A two stage interpolation system provides greater bandwidth for signals compressed and expanded by interpolation, for example video signals displayed in a zoom or enlarged mode. A finite impulse response filter generates from a first signal of digital samples a second signal of digit
5345272 Delay matching for video data during expansion and compression September 6, 1994
Video luminance data from a video signal is selectably compressed and expanded in a first signal path including a first line memory. A second line memory in a parallel signal path processes video chrominance data from the video signal. A control circuit generates respective timing si
5345270 Managing letterbox signals with logos and closed captions September 6, 1994
A video display control system comprises: a video display having a wide format display ratio; a letterbox detector for sampling video information in pictures represented by input video signals having a letterbox format and generating a control signal for enlarging the pictures for su
5313303 Aspect ratio control for picture overlays May 17, 1994
A picture overlay system assures proper image aspect ratios for picture overlays. The system comprises a video memory and a control circuit for writing and reading information from a video signal into and out of the video memory, the information relating to video data. A reading circuit
5311309 Luminance processing system for compressing and expanding video data May 10, 1994
A circuit for compressing and expanding video data comprises a FIFO line memory and an interpolator. A timing circuit generates control signals for writing data into the line memory and for reading data from the line memory to compress and expand the data. The interpolator smooths the da
5309234 Adaptive letterbox detector May 3, 1994
A video display control system automatically controls a video display responsive to detection of letterbox format input video signals having varying format display ratios. A detection circuit continuously detects the first and last lines of active video in a video signal. A memory st
5299007 Vertical reset generation system March 29, 1994
A video display control system comprises a display for the video signal, a vertical zoom circuit for generating from the video signal a picture having a vertical height greater than the display, and, a vertical panning circuit for displaying a selected portion of the picture on the displ
5294987 Field to field vertical panning system March 15, 1994
A television apparatus includes a display for a video signal representing a picture. The video signal has a vertical synchronizing component defining fields of horizontal lines which can have other than a standard number of horizontal lines per field under certain operating conditions. A
5289284 Video processing circuit with line memory control February 22, 1994
A line memory and control system comprises a line memory, for example a first in first out (FIFO) device. A comparator compares a first value, specifying a location in the horizontal line period where reading or writing of the line memory is to begin, with a second value, fixing pixel
5287189 Displaying an interlaced video signal with a noninterlaced video signal February 15, 1994
A video display unit and deflection system are synchronized with a first video signal. A detecting circuit determines whether the first video signal has more than one field type. A second video signal has more than one field type. A multiplexer combines the first and a second video s
