  • Patent number: 7532805
    Abstract: An AV data recording/reproducing device is connected to a digital broadcasting tuner and the like via an IEEE1394 bus, in order to realize high-speed transfer when duplicating or transporting AV data between devices such as audio-visual data recording/reproducing devices. A synchronous transfer input/output portion inputs and outputs stream data that are AV data by isochronous transfer with an MPEG-2 transport stream. A recording control portion and a reproduction control portion generate timestamped data and reproduce the stream data, and an HDD stores the timestamped data. An asynchronous transfer input/output portion asynchronously inputs and outputs the timestamped data by SBP-2 transfer. Consequently, the timestamped data that can reproduce the stream data are transferred at high speeds, regardless of an actual time required for performing the display or the like of the stream data.

  • Publication number: 20090067535
    Abstract: A transfer device for receiving packets that were transmitted by a device in a home network onto a transmission path, and transfers the received packet to another device. The stream to be transferred is classified into three types: (i) a type where each of packets constituting the stream is not attached with a time stamp; (ii) a type where each packet is attached with a valid time stamp; and (iii) a type where each packet is attached with an invalid time stamp. The transfer device determines, from among the three types, the type of the stream to be transferred, based on a transfer source device, transfer destination device, and provider of the stream. The transfer device then selects a transmission method by which to transfer the stream, among the time stamp attachment transmission method and the PCR reference transmission method.

  • Patent number: 7346265
    Abstract: Continuous transfer of AV data without a break necessitates to perform replacement processing of a disk access unit and takes labor and time. A characteristic is that an HDD is disposed which writes AV data in a recording medium, that an AV recording/reproducing controller is disposed which, when there is a write error in writing of AV data in a disk access unit which is a minimum unit for continuously accessing the recording medium, controls the HDD such that this disk access unit will be skipped and said AV data will be written in the next disk access unit, that skip processing judging means is disposed, and that a replacement area is not formed in the recording medium.
