摘要： A video signal processing system for recovering a plurality of frequency interleaved information components modifies a comb filtering function during a particular mode of operation to increase the resolution associated with the recovered information components. For example, during a first mode of operation, comb filtering operates to recover luminance and chrominance components of a color television signal. During a second mode of operation corresponding to absence of a chrominance component, the comb filtering function is modified by bypassing portions of the filtering function. During the second mode of operation, substantially the full bandwidth of a luminance component is recovered.

摘要： A delay correction circuit includes a source (15) of a clock signal and a source (5) of a timing signal asynchronous with the clock signal. A timing signal detector (10) is responsive to the clock signal and the timing signal, and is properly operative only when the timing signal is stable for a predetermined time period around the clock signal. A control circuit (70) conditions utilization circuitry (80) to operate after a delay time after the timing signal is detected. Adjusting circuitry (10, 20, 30, 40, 50, 60) conditions the control circuit (70) to adjust the delay time if the timing signal was not stable within the predetermined time period.

摘要： A system and method for displaying still video images related to video content in an interactive broadcast television system. The system and method of the present invention may also be used for simulating an Internet home page on an interactive television system. The present invention thus supports hyperlinked web-like navigational capabilities in an interactive television system. According to the method of the present invention, the video delivery system provides or broadcasts one or more audio/video channels each comprising video content and also provides or broadcasts at least one still image channel comprising a plurality of still video images, preferably MPEG-2 compressed still images. The user or viewer can select options displayed on the television screen to view desired information. When the set top box receives user input selecting an option to view one of the linked still images, the set top box captures the requested image from the still image broadcast channel, stores the image in memory, and displays the captured still video image corresponding to the selection. The user can also request to view an image which is not currently being transmitted by the video delivery system. In this instance, the system provides user requested still images "on demand" on a dedicated "search" channel. The user can thus selectively navigate between the video content and stills in a web-like hyperlinked fashion.

摘要： An adaptive decoder (25) generates a program representative datastream in selectable, encrypted or decrypted form. A method for adaptively processing input encrypted program data with an associated encryption code provides (110, 115) either an encrypted or a decrypted program output. In an encrypted mode, encrypted program data (47) and an associated encryption code is exported to an output port. In a decrypted mode, input encrypted program data is decrypted (50) using an encryption key derived from the encryption code to provide decrypted program data. The decrypted program data is exported to the output port. Non-encrypted program data is exported to an output port (95) in a selectable non-encrypted mode.

摘要： Program specific information (PSI) is formed (115) suitable for use in recovering data content of a program in the form of a packetized datastream. Packet indentifiers (PIDs) that identify individual packetized datastreams constituting the program are renumbered and corresponding packetized datastreams that constitute different programs are given the same PID (115). A program map table (PMT) is created that (115) associates the renumbered PIDs with the individual packetized datastreams constituting the program. A program association table (PAT) is also created (115) for associating the program with PIDs that identify packets comprising the PMT. A parameter may be employed within the PSI to indicate that the PSI is to be applied in subsequent processing of the program irrespective of a substantive difference between the PSI and previous PSI content. In additon, the PSI may incorporate a version number that is varied between successive occurrences of the PSI irrespective of substantive change in PSI content. One or more private data elements may also be included in the PMT to describe the program.

摘要： Apparatus for combining an auxiliary image and a main image includes a source of a main image video signal and a source of samples representing an auxiliary image video signal having successive fields. A quincunx subsampler is coupled to the auxiliary image sample source and subsamples the auxiliary image samples in either a first sample pattern in which samples are taken at a first set of horizontal locations, or a second sample pattern in which samples are taken at a second set of horizontal locations substantially midway between the first set, all in response to a control signal. A signal combiner is coupled to the quincunx subsampler and the main image signal source, and combines the main image signal and a signal representing the quincunx subsampled auxiliary image samples to generate a signal representing a combine image of the main and auxiliary images. A control circuit generates the quincunx subsampler control signal so that the quincunx subsampler takes samples in one of the sample patterns at the beginning of each auxiliary image video signal field, and in the other sample pattern after a switch time calculated so that the quincunx subsampled auxiliary image samples in the combined image all are taken by the same sample pattern.

This interface circuit comprises a source of an off-hook signal, having one state indicating an off-hook condition, and a second state indicating an on-hook condition. A circuit is coupled between the off-hook signal source and the subscriber telephone line which gradually increases the current drawn from the subscriber telephone line when the off-hook signal indicates an off-hook condition, and gradually decreases the current drawn from the subscriber telephone line when the off-hook signal indicates an on-hook condition.

摘要： A tuner (9) of a digital satellite television receiver comprises a single conversion stage which produces an IF signal at a low enough frequency to permit a SAW filter (913) to be used to perform symbol shaping as well as the normal IF filtering function. The local oscillator (911) is controlled by a phase locked loop tuning control IC normally used to control the local oscillator (911) of a tuner (9) of a conventional broadcast or cable television receiver. In an exemplary embodiment for tuning RF signals provided by a block converter (3) in the 950 to 1450 MHz frequency range, the IF has a center frequency of 140 MHz. A lithium tantalate SAW filter (913) is used in order to minimize shift of the IF center frequency with temperature and to provide the required relative IF bandwidth (i.e., the width of the IF passband divided by the IF center frequency).

摘要： A digital television system which processes television information in the form of a stream data packets representing video and audio information in compressed form, such as MPEG, includes on-screen display (OSD) provisions for displaying sophisticated graphics, such as animation, by storing graphics data in a read only memory (ROM) in the same compressed form as that used for the video information. The graphics data is transported to the same video decoding and decompression unit which processes the video data contained in the video packets to form digital signals representing video information in uncompressed form, where it is converted in the same manner as the video data to form graphic image data. A multiplexing arrangement is provided so that digital signals representing animation graphics can be multiplexed with digital signals representing static graphics image data derived from bit-mapped representations.
