Electronic equipment, method of receiving data, method of transmitting data, method of setting channel and method of grouping electronic equipment into channels
First Claim
1. A channel grouping method for grouping a plurality of electronic equipment connected to a communication bus into a plurality of groups, wherein each group communicates using a different channel on the communication bus;
- the method comprising the steps of;
acquiring information from each of the plurality of electronic equipment connected to said communication bus, said information comprising a unique identification, a speed, and a format for communication over the communication bus;
grouping said plurality of electronic equipment into the plurality of groups based on the acquired information;
displaying the plurality of groups on a display; and
automatically setting default channels for each of the electronic equipment in each of the plurality of groups by issuing a set command;
wherein the default channels are automatically set based on a broadcast channel base field of an output register or a reserved field of an input register in each of the electronic equipment;
wherein said communication bus is operable to transfer data by asynchronous data transfer and isochronous data transfer.

Abstract
It becomes possible for a user to set a transmission or reception channel arbitrarily and easily. Each of equipment connected to an IEEE 1394 bus may include a register provided within a RAM 113 to thereby set a transmission or reception default channel. If channels used in the transmission and the reception are not set when the transmission is started, then default channel may be used. When equipment is set to a channel setting mode by operating an operation section 116, a control section 112 may display a channel setting picture on a display section 115. In this state, a user may select a set channel by operating an up-key 116a and a down-key 116b of the operation section 116. Thereafter, when a user operates a “YES” key 116c, the control section 112 may write a selected channel in the above-mentioned register, and ends a default channel setting operation. A user can set the transmission or reception channel arbitrarily and easily.
