  • Patent number: 7133599
    Abstract: A realtime data recording method allows recovery of recorded file data upon occurrence of a fault for use as a readable file. Prior to recording, initial management data are generated such that the entire area on a recording medium 1 is reflected as a recording range. After the initial management data has been recorded, data recording is started. During the recording, a writing status of the recording medium (or apparatus) is set as in-writing status, and realtime sector information generated in parallel to data recording is recorded in a non-volatile memory for management of a recording status. Upon restarting after a recording fault, the in-writing status of recording medium 1 is read to see if the medium has been set open, and inconsistency between the recording information of the sector information and the in-writing status recording information is detected. Correct management data is recorded and re-recorded onto the recording medium.

  • Patent number: 7003606
    Abstract: An IRD 103 supplies broadcasting data on a bus in a desired time period. When the IRD 103 performs a reservation of the bus usage, the IRD 103 requests current bus usage information and information of the bus reservation from all devices connected by the bus, such as a DVD 104, a D-VTR 101, a D-VTR 102, a CAM 105, a TV 100, and a isochronous manager 107 of the D-VTR 101. The isochronous manager 107 and each device answer by sending the bus usage information and reservation information to the IRD 103. The IRD 103 judges a possibility of the reservation from the answer information. If the reservation is possible, it performs the reservation operation. If the reservation is impossible, then the reason is displayed on a TV 100. Therefore, it is possible to prevent a usage of a device that excesses the bus transferring capacity.
