Problems solved by technology
[0010] Unfortunately, the same method is used for digital television (DTV) as display 12' (see figure 2 ) is impractical as it would require the menu to be delivered as an MPEG-2 transport stream
The generation of such streams necessitates the integration of an MPEG encoder 15' in all peripheral devices, which greatly increases the cost and complexity of such consumer electronic devices
In addition, GUIs related to control devices and peripherals may be different and require users to use multiple remote control devices, which causes user inconvenience

Embodiment Construction
[0026] The use of the IEEE 1394 serial bus has been proposed for many applications in the home networking environment. It is being set into next generation PCs and will be used for many local peripherals including disk drives. Also, digital audio / video consumer electronics devices such as digital televisions (DTVs) and digital video recorders (DVHSs) can utilize serial buses to interconnect these devices.
[0027] IEEE 1394 is a high-speed, low-cost digital serial bus developed for use as a peripheral or backplane bus. Some of the bus's features include: dynamic node addressing, data rates of 100, 200 and 400 Mbit / s, asynchronous or synchronous mode, fair bus arbitration or arbitration and conformance with ISO / IEC 13213. image 3 Illustrated is the serial bus protocol for the IEEE 1394 serial bus 16, which is a set of three stacked layers.
[0028] The physical layer 18 includes physical signaling circuits and logic circuits that are responsible for power-up, arbitration, bu...

An apparatus and method for controlling a plurality of electronic devices, such as consumer electronic device, or the like, via a digital bus. In particular, the present invention provides for improved interoperability of such devices over the digital bus. In one embodiment, the present invention transfers identifying information from a pheripheral device to a display device during a discovery mode for providing a device selection screen having a plurality of device icons displayed thereon. The device icons are generated by the display, or controlling device, in response to identifying information, such as keywords stored in a configuration ROM of the peripheral device.
Description
[0001] This application is a divisional application of the following invention patent application: [0002] Application number: 01809365.5 [0003] Application date: May 11, 2001 [0004] Title of invention: Apparatus and method for improved device interoperability technical field [0005] The present invention relates to a system for controlling a plurality of electronic devices, such as consumer electronic devices, via an interconnection such as a digital data bus. More specifically, the present invention relates to means for managing the interoperability of such devices. Background technique [0006] The data bus may be used to interconnect electronic devices such as television receivers, monitors, video recorders (VCRs), direct broadcast satellite (DBS) receivers, and home control devices such as security systems or temperature control devices. Communication using the data bus takes place according to the bus protocol. Examples of bus protocols include Consumer Elect...
