  • Electronic device, method for using electronic device, and electronic device system for reserving bus usage time on a bus to conduct communications between electronic devices
    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.
