Abstract: A signal processing apparatus for changing the frequency characteristics of an audio or video signal allows a signal to pass a transmission circuit (11) in a positive time sequence and then, transmit through another transmission circuit (14,15) having the same transmission characteristic in a reverse time sequence to the positive time sequence by appropriate writing to and reading from memory circuit (12,13,16,17). Also, while atransmission circuit is arranged to have a zero-phase characteristic, each segment of a continuous signal is processed throughout a period which is equal to at least two times a duration of an impulse response duration of the transmission circuit. Hence, unwanted waveform errors appearing at discontinuous regions of the signal will be eliminated.

Abstract: An apparatus serving as a digital videocassette recorder (VCR) for recording analog video and audio signals as digital signals. The apparatus serves also as a digital data storage drive. The digital VCR and the storage drive share common circuitry and a common magnetic recording medium. This reduces the cost and enhances the efficiency at which tracks are used. The apparatus has a large storage capacity. The apparatus divides input digital data into two parts and performs error correction encoding for each of these two data parts to form sync blocks. These sync blocks are recorded in an audio signal recording area and a video signal recording area, respectively, on the recording medium. Error correction codes used during reading of digital data are the same as those used during recording of video and audio signals. The same track structure and the same sync block structure are used for these two modes of operation.

Abstract: A digital answering system (100 ) automatically answers incoming calls from a telephone network and records audible messages. The answering system includes a calendar memory (110) which stores the present time-of-day and day-of-year. The answering system also includes stored playback commands which instruct it to generate telephone ringing signals at a predetermined time and then play back a recorded audible reminder message. The answering system may be a stand-alone unit which is parallel-connected to the telephone network and which generates an audible alerting signal at the predetermined time. Alternatively, the answering system (100) may be series-connected between the telephone network and a pair of conductors to which one or more extension telephones are connected in parallel. In the latter case, recorded audible reminder messages are delivered to an extension telephone after the answering system causes them to ring at the predetermined time. The playback command and audible reminder message are simultaneously entered, either remotely or locally, into the answering system.
