A system for minimizing screen burn on a display screen caused by the display of video images that do not occupy the entire area of the display screen includes video image processing circuitry for formatting a received video signal to display an active image of the video signal on a portion of the display screen, and for displaying a screen saver on portions of the display screen that are not occupied by the formatted active image. A screen saver library provides a screen saver from a plurality of screen savers. Each screen saver in the plurality of screen savers occupies portions of the display screen that are not occupied by an active image.

348565, 348554

A method and device for adapting an existing analog television receiver to receive and decode both analog and digital television signals. A digital module is provided within the analog television receiver and its output is provided to the picture-in-picture (PIP) interface of an analog module within the receiver. The digital signal then has the benefit of using the picture improvement circuitry located within the analog module and there is no need to modify the analog module which has been in the cost optimization process for years.

For use in a digital television receiver, there is disclosed a system for receiving audio and video digital signals. The system comprises a digital network interface coupled to a digital main board for receiving baseband audio and video digital signals and a digital video decoder coupled to the digital network interface for decoding audio and video digital signals from the digital network interface. The digital video decoder sends the decoded signals to the digital main board. The system also comprises an analog television chassis having an input that is capable of receiving audio and video analog signals. The digital main board digitizes the analog signals into a digital transport stream prior to processing.

A method and apparatus for the selective peaking of portions of a video signal is provided. The video signals, such as those transmitted in compressed form, in accordance with MPEG Standards, can be presented as blocks of data encoded using Discrete Cosine Transforms (DCT). The Discrete Cosine Transform coefficients corresponding to the chrominance values of the signal can be obtained and analyzed. The analysis and corresponding amounts of enhancement (peaking) can be performed on a block-by-block, I-frame by I-frame, basis to selectively peak portions of a video signal. If the DCT coefficients for a portion of the signal exceed or fall within a pre-selected value or range, that portion of the signal can be subjected to peaking. For example, if the high frequency horizontal DCT coefficients exceed (or fall within) a pre-set threshold value or range, a horizontal peaking circuit can be set to peak that portion of the signal. The signal processor can be set for gain in proportion to how much the coefficients exceed the threshold.

A device for automatically providing program information to a television display upon detection of an event in the program. The event being a user definable event. The device also provides automatic PIP display of the program having the event and a delay of the event so that it is not missed by the viewer.

A method and system for synchronizing signals. First and second signals are sent (compressed or uncompressed) from a source to a receiving apparatus of a receiving system. The first signal has content of a first modality (e. g. , audio) and the second signal has content of a second modality (e. g. , video). The first and second signals are to be displayed on a display apparatus of the receiving system. The first and second signals have been time-synchronized at the source. If the first and second signals are not synchronized in time when received at the receiving apparatus, then the first and second signals may be time-synchronized at the receiving apparatus either manually or through timestamping of both signals at the source, in conjunction with use of a real-time clock at the receiving apparatus.

A method and system to process a spectrum of radio frequency (RF) signals. An analog to digital (A/D) converter is adapted to sample and digitize a spectrum of radio frequency (RF) signals. The spectrum of RF signals include a plurality of modulation techniques. The A/D converter is further adapted to sample the spectrum at a rate that is at least twice the frequency of the highest frequency signal that is contained within the spectrum. The digitized data stored in a memory device. A processor is adapted to process the digitized data.
