Publication number: 20020184632Abstract: A peripheral device that can be configured, for example, in a personal computer (PC) system, between the PC processor and the PC monitor. The peripheral device receives video signals from the PC processor for display on the PC monitor. In addition, the peripheral device receives television (TV) signals from a TV source, for example, via a standard TV connection. The peripheral device combines the video content of the TV signals with the video signals received from the PC processor to generate a combined video signal for display on the PC monitor. The peripheral device supports web-based applications where the web-page layout is received by the PC system via a conventional Internet connection, where the peripheral device overlays the video content of the TV signals over appropriate corresponding windows in the web-page layout. In this way, bandwidth in the PC's Internet connection does not have to be used for streaming media delivery of TV video content.Type: ApplicationFiled: May 30, 2001Publication date: December 5, 2002Inventor: Glenn A.

Patent number: 5530484Abstract: An adaptive scan format converter (14, FIG. 1; FIG. 2) at a transmitter/encoder of a video signal processing system such as a high definition television (HDTV) system, as a function of what format is desired for coding and transmission via an output channel. Similarly, at a receiver, a received scan format is automatically converted (36, FIG. 1; FIG. 2) to a desired format for display as needed. For example, a received interlaced signal (I) will be automatically converted to progressive (P) format to be compatible with a progressive scan display device (39). A received progressive signal will be passed to the display device without format conversion. Automatic scan conversion is performed seamlessly so that, for example, the conversion between progressive main television program material and interlaced commercial material is produced without artifacts and is essentially invisible to a viewer.Type: GrantFiled: May 19, 1995Date of Patent: June 25, 1996Assignee: Thomson Multimedia S.AInventors: Bhavesh B. Bhatt, Nicola J. Fedele, Glenn A. Reitmeier

Patent number: 5253041Abstract: A preprocessor for conditioning interlace-scan video signals for frame based compression, includes apparatus to accept fields of interlace-scanned video and provide fields of interlace-scanned luminance and chrominance component signals. The fields of interlace-scanned luminance component are combined into respective frames of luminance signal and applied to compressor apparatus for further processing. The fields of interlace scanned chrominance components are independently processed at the field level to generate lines of chrominance values which are interstitial to the lines of the original chrominance values and at a lesser pixel and line density. The independently processed fields of interlace-scanned chrominance signals are combined into respective frames of chrominance component signals and applied to compressor circuitry for further processing. Performing the chrominance signal interpolation and subsampling at the field level tends to eliminate a majority of color distortions around moving images.Type: GrantFiled: May 26, 1992Date of Patent: October 12, 1993Assignee: General Electric CompanyInventors: Charles M.

Patent number: 4626895Abstract: An adaptive system for separating chrominance and luminance components from composite video includes a delay element having a central output tap and pairs of further output taps symmetrically disposed about said further tap. Samples from each pair of taps are subtractively combined, filtered and scaled. These samples are then applied to a decoder which determines the pair of taps providing the smallest filtered and scaled difference. Samples from the pair of taps generating the smallest difference and samples from the central output tap are then combined to produce either comb filtered chrominance/luminance or bandpass/lowpass filtered chrominance/liminance.Type: GrantFiled: May 22, 1985Date of Patent: December 2, 1986Assignee: RCA CorporationInventor: Glenn A.

Patent number: 4622577Abstract: In a television receiver, a demultiplexer for a high definition multiplexed analog component television signal provides samples of each component signal. A group of samples for each component signal is selected according to the aspect ratio of the television receiver display, and according to the aspect ratio of the picture contained in the high definition multiplexed analog signal so that the selected group is the one that provides picture information which fits the aspect ratio of the display. The selected samples for one scan line are first stored during the active scan line time and then read out sequentially during the subsequent scan line time. The stored samples of each component signal are read out sequentially during substantially the same time period to provide the required Y, U, V signals. A similarly designed demultiplexer may be used to process an extended aspect ratio frequency multiplexed signal such as a high definition NTSC-formatted signal.Type: GrantFiled: February 3, 1984Date of Patent: November 11, 1986Assignee: RCA CorporationInventors: Glenn A. Reitmeier, Curtis R. Carlson

Patent number: 4621287Abstract: High horizontal spatial frequency information may be transmitted through a limited bandwidth channel by means of spatial-temporal frequency interleaving techniques. To transmit both frequency interleaved high horizontal spatial frequency information and diagonal spatial frequency information in one video signal, the corresponding spectra containing these two types of information are time-multiplexed prior to transmission. At the receiver, the interleaved high horizontal frequency information is extracted, relocated to its original horizontal position, and recombined with the diagonal frequency information to generate a baseband video signal.Type: GrantFiled: May 29, 1984Date of Patent: November 4, 1986Assignee: RCA CorporationInventors: Glenn A. Reitmeier, Curtis R. Carlson

Patent number: 4621286Abstract: The image represented by a video signal contains an associated image spectrum defined within a spatial-temporal frequency volume. From this video signal, a second video signal is produced that represents spatial-temporal carrier modulation of a spectral section of the image spectrum into an interleaved location adjacent the image spectrum. To reduce the visibility of aliasing artifacts, the interleaved spectral section is made to be of reduced amplitude relative to its original amplitude in the image spectrum. To reconstruct the spatial-temporal frequency spectrum of the image at the television receiver, the video signal containing the frequency interleaved spectrum is processed in a complementary manner that represents spatial-temporal carrier modulation of the interleaved section to restore that section to its original position in the image spectrum. At the same time, the amplitude of the restored section is increased.Type: GrantFiled: May 29, 1984Date of Patent: November 4, 1986Assignee: RCA CorporationInventors: Glenn A. Reitmeier, Curtis R. Carlson

Patent number: 4605963Abstract: A digital TV system reduces the data rate by transmitting or recording only bytes representing half of the sampled pixels. Steering bits are also transmitted that tell which of the transmitted bytes are the closest match to the untransmitted bytes so the pixels represented by the later can be reconstructed. The steering or control bits are repeated for subsequent omitted bytes unless it no longer indicates a match within a selected tolerance or threshold.Type: GrantFiled: August 15, 1983Date of Patent: August 12, 1986Assignee: RCA CorporationInventors: Glenn A. Reitmeier, Curtis R. Carlson

Patent number: 4597007Abstract: A frame comb filter system includes circuitry for reducing motion induced artifacts in reproduced images. Frame comb filtered chrominance signal is line comb filtered to extract motion induced luminance cross components therein. The luminance cross components are added to frame comb filtered luminance signal to reduce motion induced luminance signal errors. The corrected luminance signal is then subtracted from composite video signal to produce the chrominance component of composite video.Type: GrantFiled: February 6, 1984Date of Patent: June 24, 1986Assignee: RCA CorporationInventors: Glenn A. Reitmeier, Christopher H. Strolle

Patent number: 4518996Abstract: A synchronization system for serial digital television signals compares successive sync signals to form an error signal and also delays the digital signals. The information signal delay is changed during loss of signal by an amount in accordance with the error signal to resync the signal. Thus valid information occuring before loss of synchronization is utilized. The delay means can comprise a pair of RAMs.Type: GrantFiled: March 21, 1983Date of Patent: May 21, 1985Assignee: RCA CorporationInventors: Glenn A. Reitmeier, Charles R. Thompson
