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: A progressively scanned video signal is encoded into temporal sum and difference components for transmission. The sum signal is temporally filtered, decimated and time expended to be compatible with interlaced receivers. The difference signal, also temporally filtered, decimated and time expanded, is conveyed via single or separate channels with the sum signal to a progressive scan receiver for reconstitution of the original progressive scan signal. Modified quadrature amplitude modulation is used to convey the sum and difference signals in a common channel.

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.

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: In a transmission channel, such as a tape recorder, errors in code words usually occur in bursts. Further, it is usually possible to detect only some of the erroneous code words. To conceal undetected erroneous code words, concealment starts before, and continues after, a detected erroneous code word. Thus the undetected erroneous code words in an error burst have a high probability of being concealed.
