  • Publication number: 20010003519
    Abstract: When a recording condition judgement section (28) determines a recording condition of the recording of data onto a disk, and the recording is discontinued in response to the decision, a recording speed setting section (29) switches a recording speed to a speed one step slower than the previous recording speed. With this arrangement, when the recording condition is inferior, the recording is discontinued to thereby avoid a recording failure. Moreover, the recording speed is corrected stepwisely so that a disk adaptable recording speed can be set. Further, a recording start position at which to start additional writing is detected by the recording start position detection section (26), and the recording data is synchronized with the recording data by a synchronism setting section (27) to ensure successiveness before and after the recording data connection due to additional writing to the disk, before the recording is resumed.

  • Publication number: 20010003520
    Abstract: A touch sensitive transport mechanism for an electronic apparatus such as a compact disc player. The transport mechanism has a drawer with a front push panel which can be lightly pushed by the operator. This allows the operator to directly control the operation of the electronic apparatus without the need for separate control buttons, thereby physically interacting with the electronic apparatus. A motor drives the drawer between open and closed positions. The mechanism has optical sensors which detect when the drawer is pushed, and the motor provides a feedback force against the push of the operator. When the drawer is in the closed position, a short push increments between tracks on a compact disc, an intermediate push causes playback of the compact disc to stop, and a long push causes the motor to drive the drawer to the open position.

    Abstract: A novel mechanism is disclosed by which a sender can direct information such as an audiovisual signal to a particular recipient's audiovisual display device, such as a cable television set and, thereby, share information between the sender and the recipient. In one embodiment of the invention, a calling party originates a telephone call and associates that telephone call with audio-visual information that exists on the caller's personal computer or on an Internet server. The called party answers the call, and can tune an associated cable television to the appropriate channel in order to view the audiovisual information. The caller can modify the audio-visual information during the call. Accordingly, the current invention ties together the telephone, cable, and IP networks in a manner that does not require large investments from cable or telephone service providers.

    Abstract: The invention provides an apparatus for reproducing a plurality of image data which has been recorded in a plurality of independent areas on a disk-shaped recording medium and specified so as to be reproduced in predetermined order, from the disk-shaped recording medium by using a pickup mechanism. The apparatus has a memory for storing the reproduced image data and a memory control unit for reading out the image data stored in the memory in the predetermined order, and controls whether the image data recorded in the plurality of areas is reproduced in order different from the predetermined order and written in the memory or not, on the basis of position information indicative of positions of the plurality of areas on the disk-shaped recording medium, a capacity of the memory, and a seeking time between the plurality of areas by the pickup mechanism.

    Abstract: A signal recording/reproducing method and apparatus, signal record medium and signal transmission/reception method and apparatus, whereby a signal recorded on a signal record medium can be identified as being an original signal or a copied signal. A CPU 11 generates, at a pe-set time interval, an identification signal having a meaning at a pre-set time interval, and an identification signal addition circuit 3 adds the identification signal to the video signals and/or the audio signals. A sector forming circuit 5 and circuit components up to a recording/reproducing head 14 record the video signals and/or the audio signals and the ancillary identification signal on an optical disc 12.

  • Publication number: 20010003554
    Abstract: It is made possible to record, on a recording medium on which original image data before compression is recorded, data resulting from a first coding processing performed when coding the data by a variable rate compression and coding system and to code quickly in real time when performing a second coding processing from that recording medium. Video data is reproduced by a VTR 300 from a master video tape 10 on which source video data is recorded and the first coding processing is carried out at a compressing and coding apparatus 100. The bit rate, allocation data, etc. obtained by this coding processing are stored in a predetermined region of the master video tape 10 via the VTR 300. When the master video tape 10 is used, the second coding processing can be quickly carried out without reading the bit rate data etc. from another apparatus.
