    摘要： This invention relates to a method and apparatus for processing a color video signal. The processing method separates an input composite color video signal into a luminance signal and chrominance signal, demodulates the separated chrominance signal into color difference signals, stores the separated luminance signal and color difference signals in a memory, reads out the luminance signal and color differnece signals in units of 1-field period from the memory, implements the extension or reduction of the field period length alternately for every certain number of fields in reading out the luminance signal and color difference signals from the memory thereby to fix the phase relation between a residual chrominance signal component in the luminance signal read out of the memory and a chrominance signal produced by modulating the color subcarrier with the color difference signals read out of the memory, implements an intended signal processing for the readout signals, modulates the color subcarrier with processed color difference signals to produce a chrominance signal, and mixes the chrominance signal with processed luminance signal to produce a composite color video signal.

    摘要： A digital information signal transmitting/receiving method and system having a transmitter for transmitting an encrypted digital information signal and a plurality of receivers for receiving the encrypted digital information signal from the transmitter. The transmitter simultaneously distributes a plurality of identification codes associated with the receivers at a time ahead of the digital information signal. The receivers detect whether a particular identification code assigned to the receiver was included within a received plurality of identification codes. When the particular identification code has been detected as having been received the received encrypted digital information signal is decrypted into the original digital information. In order to request that a particular identification code be included so as to allow access to a program, either one of the receivers or the recorders each generate an information request signal. The transmitter is responsive to the information request signals to add to the digital information signal at a time ahead of the digital information signal, identification signals for identifying the receivers or the recorders which generated the information request signals, thereby producing a transmission signal formed of those signals, and to distribute this transmission signal to the receivers. The recorders control the received information signal to be recorded in response to the identification signals received by the receivers.

    摘要： A support method for helping the user find a desired program from a collection of recorded television programs easily and quickly, and a recording/reproducing apparatus using this method. The recorded program viewing support system, when recording a television program, records electronic program information on the program, classifies the electronic program information according to predefined program category criteria, and successfully assigns predefined category numbers (recording channels) to the program to be recorded. Before the user views a recorded program, the user specifies the number of the recorded channel. A recorded channel number is allocated with a category item and hence the user can easily know the contents of the recorded programs. The user can change the channel number successively or directly specify it by using a remote controller to find a desired program easily and quickly. When disk media such as HDD and DVD-RAM are used as a storage in particular, the recorded programs can be randomly accessed allowing the user to zap through recorded programs.
