Abstract: A transmitter unit of a remote control system includes a key function display unit for identifying the function of key elements of the transmitter unit at various steps of a control sequence for one or more controlled devices. The memory for storing character-representative information for identifying the functions of the key elements of the transmitter and corresponding function control instructions is contained in the controlled devices rather than in the transmitter unit. This allows for the addition of new controlled device without modification of the transmitter units.

Abstract: An adaptive error concealment system uses either a horizontal or vertical average as a replacement pixel for an erroneous pixel. The choice is dependent upon the amount of horizontal information in at least one adjacent horizontal line. This avoids errors if certain horizontal or vertical stripe patterns are present in the video signal.

Abstract: 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.

Abstract: A system is provided for filtering and demodulating digital color mixture signals, wherein the signals are filtered to remove out-of-band noise prior to completion of the demodulation process. Interleaved digital chrominance signal samples are first demodulated by a signal related in frequency to the video subcarrier to obtain interleaved color mixture signal samples of different sampling phases at baseband frequencies. The interleaved color mixture signal samples are applied to a digital filter at a rate which is a multiple of the color subcarrier frequency. The weighting coefficients of the filter are selected to obtain a bandwidth which passes the color mixture signal while removing out of band noise. Since the input signal sequence to the digital filter contains interleaved color mixture signal samples, alternate stages of the filter shift register are tapped, so that the output sequence will comprise filtered and interleaved color mixture signal samples. An output sampling switch accomplishes phase demodulation of the output sequence by selecting samples at a reduced sampling rate in accordance with the Nyquist criterion of the color signals and produces either one or two output sequences of filtered and fully demodulated color mixture signals. Tapped shift register stages of the digital filter may be coupled to two different sets of weighting coefficients and signal combining stages. The filter outputs may thus exhibit unequal bandwidths for filtered color mixture signals, which are commensurate with the desired bandwidths of the filtered signals.
