  • Patent number: 6160491
    Abstract: A remote control system for controlling an electronic device includes a remote controller and a remote control interface. The remote controller includes a memory for storing a plurality of control data respectively indicating the relationship between a plurality of control signals and functions of the electronic device corresponding to the plurality of control signals; a trigger signal transmitter for transmitting a trigger signal for causing the electronic device to transmit a response signal which is specific to the type of the electronic device; a receiver for receiving the response signal; and a control signal transmitter for selecting control data specific to the type of the electronic device from the plurality of control data based on the response signal, generating one of the control signals, and transmitting the generated control signal.

  • Patent number: 5513011
    Abstract: A method and apparatus for recording/reproducing video signals on or from storage media. A video signal is divided into k video blocks in a time-axis direction, wherein k is an integer not less than 2, finding a block skip interval s which is an integer satisfying an equation s=(pk+1)/n when p is an integer not less than 1 and n is an integer not less than 2. The k video blocks are interleaved in order ofi= s(j-1)}mod k+wherein i is an integer satisfying a relation 1.ltoreq.i.ltoreq.k and representing a block number of the video signal, and j is an integer satisfying a relation 1.ltoreq.j.ltoreq.k and representing an allocation block number on a storage medium (FIGS. 2(A) and 2(B)). And, thus interleaved video blocks are allocated on the storage medium (312).

  • Patent number: 4944032
    Abstract: A multiplex signal processing apparatus in a singal transmitting and receiving system includes at the transmitting side: a first amplitude-modulator for modulating a first carrier by a main signal to obtain a vestigial sideband, amplitude-modulated main signal; a second amplitude-modulator for modulating a second carrier which has the same frequency but differs in phase by 90.degree. from the first carrier by a multiplex signal to obtain a double sideband, amplitude-modulated multiplex signal; an inverse Nyquist filter for filtering this signal to obtain a vestigial sideband, amplitude-modulated multiplex signal; and an adder for adding the vestigial sideband, amplitude-modulated main and multiplex signals to obtain a multiplexed signal.
