摘要： An encoder-modulator for coupling a digital baseband television signal to a VSB digital television receiver that includes filters, equalization circuitry, and forward error correction circuitry for correcting signal impairments that are below a given threshold. The encoder-modulator processes the baseband signal for low power transmission on an RF channel with less-than-nominal bandpass characteristics. A coaxial cable or other low noise communication link directly connects the RF signal to the RF input of the television receiver. Any errors or signal impairments in the transmitted signal that are below the predetermined threshold are corrected by the filters and equalization circuitry built into the VSB digital television receiver.

摘要： A high definition television transmitting system includes a source of high definition analog RGB video signals which are converted to corresponding digitally encoded signals and thereafter compressed by a video encoder to a six megahertz bandwidth. The compressed data is formatted by a transmitter and processed in accordance with a Reed-Solomon error control system for broadcast as an NTSC-type broadcast signal. A high definition television receiver includes a high definition signal receiver coupled to the transmitter by a transmission link. The receiver extracts the compressed video, audio and ancillary data signals and applies a Reed-Solomon error correction thereto. The compressed video data is reconstructed by a video decoder and processed for high definition display. A high definition digital video tape recorder is coupled to the transmitter by an interface and format converter facilitating both recording and playback functions of the digital video tape recorder while maintaining the Reed-Solomon error control. The format converter provides compatibility between the high definition transmitter and the digital video tape recorder.

摘要： One version of a microprocessor based auto dialer for a PPV television system includes an IR receiver for receiving impulse "buy" decisions, in the form of one or more key pad entries from a portable IR transmitter, and a number generator for adding the appropriate digits to a partial ANI telephone number stored in memory. In another version, the auto dialer is connected to the serial port of a PM type CATV decoder and a PPV identifier and telephone number may be downloaded to the ANI auto dialer to eliminate the permanent storage of the telephone number and to simplify subscriber interaction. The auto dialer dials the telephone number of the cable head end. Further embodiments include carrier current interfaces between the IR receiver/detector and the auto dialer, and between the decoder and the auto dialer.

摘要： An optical video disc has a multi-turn spiral track which stores a frequency modulated carrier modulated with program information in accordance with NTSC format. The recording is further characterized by the fact that the phase of the chroma subcarrier at the start of one convolution of the record track is substantially the same as that of the end of the convolution. In the playback process, the disc is rotated at a speed such that the chroma subcarrier is integrally related to the frequency of disc rotation.
