Tv Signal Transmission Systems And Methods

US Patent:
5040063, Aug 13, 1991
Filed:
Oct 23, 1989
Appl. No.:
7/408158
Inventors:
Richard W. Citta - Oak Park IL
Ronald B. Lee - Chicago IL
Assignee:
Zenith Electronics Corporation - Glenview IL
International Classification:
H04N 704
US Classification:
358141
Abstract:
A hybrid television signal of less transmission power or better signal to noise performance is made up by removing low frequency analog components from the video signal, digitizing them and sending them as data in non-active video portions of the transmitted signal. A two step hybridization process, with the first step removing the line averaged value of the video components of the video signal and the second step removing the remainder of the video components under 200 KHz, is described. Temporal filtering, signal pre-emphasis, compression, time dispersion and double sideband suppressed carrier modulation about a centered carrier are disclosed for reducing peak signal amplitudes and for minimizing co-channel interference to and from NTSC signals. Time dispersion is done horizontally, vertically or both to reduce the peak signal amplitudes. Time dispersion in conjunction with low frequency removal and temporal filtering is preferred.

Catv Scrambling System With Compressed Digital Audio In Synchronizing Signal Intervals

US Patent:
4688246, Aug 18, 1987
Filed:
Dec 20, 1985
Appl. No.:
6/811928
Inventors:
Carl G. Eilers - River Forest IL
Ronald B. Lee - Chicago IL
Rudolf Turner - Vernon Hills IL
Assignee:
Zenith Electronics Corporation - Glenview IL
International Classification:
H04N 7167
US Classification:
380 9
Abstract:
A CATV television system has the sync and color subcarrier reference information replaced in the horizontal blanking intervals with compressed digital audio data. The digital audio data is in the form of a modified duobinary signal having data sampling points selected to coincide with the zero crossings of a color reference subcarrier. A phase locked loop provides the master clock for the signal generator and the data sampler. A horizontal interval detector circuit recovers a 1. 8 MHz CW signal of greater than one half line duration, followed by a white horizontal identification pulse of 4. 7 microseconds width, that are supplied in place of the pre-equalizing, vertical sync and post equalizing pulses in the vertical interval. CODE 1TV60CATV.

Tv Signal Transmission Systems And Methods

US Patent:
5043812, Aug 27, 1991
Filed:
Aug 13, 1990
Appl. No.:
7/566784
Inventors:
Richard W. Citta - Oak Park IL
Ronald B. Lee - Chicago IL
Assignee:
Zenith Electronics Corporation - Glenview IL
International Classification:
H04N 704
US Classification:
358141
Abstract:
A hybrid television signal of less transmission power or better signal to noise performance is made up by removing low frequency analog components from the video signal, digitizing them and sending them as data in non-active video portions of the transmitted signal. A two step hybridization process, with the first step removing the line averaged value of the video components of the video signal and the second step removing the remainder of the video components under 200 KHz, is described. Temporal filtering, signal pre-emphasis, compression, dispersal and double sideband suppressed carrier modulation about a centered carrier are disclosed for reducing peak signal amplitudes and for minimizing co-channel interference to and from NTSC signals. In an FM implementation, the benefits of the hybrid signal are realized as a reduction in bandwidth and consequent improved noise performance. The hybrid signal system is uniquely adapted to a high definition television signal in a limited frequency channel.

US Patent:

Inventors:

High Definition Television System

US Patent:
5029002, Jul 2, 1991
Filed:
Aug 31, 1988
Appl. No.:
7/239155
Inventors:
Richard W. Citta - Oak Park IL
Ronald B. Lee - Chicago IL
Assignee:
Zenith Electronics Corporation - Glenview IL
International Classification:
H04N 700, H04N 1100
US Classification:
358141
Abstract:
A high definition television system includes an encoder for encoding a video source signal having a horizontal bandwidth of about 28-30 MHz for transmission through a 6 MHz RF channel. The video source signal is provided in the form of a plurality of horizontal video lines occurring at a vertical rate equal to the NTSC field repetition rate and at a predetermined horizontal rate greater than the NTSC horizontal scanning rate. The video lines of the source signal are encoded for transmission at NTSC vertical and horizontal rates, with the lines representing the lower frequencies of the video source signal being transmitted at a higher temporal rate than the lines representing the higher frequencies. The transmitted lines are converted to a plurality of display lines by a receiver for display at a vertical rate equal to the NTSC field repetition rate and at a horizontal rate equal to the predetermined horizontal rate.

Temporal Decorrelation Of Block Artifacts

US Patent:
5107348, Apr 21, 1992
Filed:
Jul 11, 1990
Appl. No.:
7/551696
Inventors:
Richard W. Citta - Oak Park IL
Stephen M. Dicke - Wheeling IL
Ronald B. Lee - Chicago IL
Assignee:
Zenith Electronics Corporation - Glenview IL
International Classification:
H04N 713
US Classification:
358136
Abstract:
A video signal comprising a successive series of frames is sub-band coded to derive a plurality of groups of coefficients for each frame. Each group of coefficients comprises a spectral representation of the video content of a respective portion of the frame, which portions are spatially decorrelated relative to the corresponding portions of the immediately preceding and immediately following frames to reduce block artifacts in the reproduced image.

System For Negating The Effects Of Dc Offsets In An Adaptive Equalizer

US Patent:
5060067, Oct 22, 1991
Filed:
Nov 26, 1990
Appl. No.:
7/618188
Inventors:
Ronald B. Lee - Chicago IL
Larry E. Nielsen - Chicago IL
Assignee:
Zenith Electronics Corporation - Glenview IL
International Classification:
H04N 521
US Classification:
358167
Abstract:
An adaptive filter for equalizing a received information signal is controlled by an error signal generated in response to a reference signal alternately transmitted in inverted and non-inverted form. The received reference signal transmitted in inverted form is reinverted prior to generating the error signal for negating the effects of DC offsets acquired by the reference signal during transmission and reception.
