Embodiment Construction

[0026] The framework of the following exemplary embodiments of the invention is that HAVi is applied to IP type networks, but obviously the invention is not limited to this type of network, but can be used to apply to any type of network. The invention can also be used in the context of specifications other than HAVi, if devices connected to the network are to be discovered.

[0027] figure 1 Represents the structure of the HAVi stack defined in the HAVi specification over a network consisting of 1394 buses. The HAVi stack is programmable in JAVA via API ("Application Programming Interface") 1.1. A stack of a device may comprise a module for controlling the device (DCM, "Device Control Module") or a module for controlling the functionality of the device (FCM, standing for "Function Control Module") 1.7. The stack may also include a native module 1.8. Registry 1.2 ("Registry") maintains a base of all devices on the network. The event manager 1.3 is responsible for transmit...

Abstract

The invention relates to audio and video interoperability over networks based on network technologies other than the 1394 bus. The invention relates more particularly to a method of discovery, by a device connectable to a communication network, of the other devices connected to this network, which comprises a step of connection of the device to the said network, a step of despatching of an announcement message containing autodescription information describing the device destined for all the other devices connected to this network, a step of despatching of an autodescription information request message to all the other devices connected to this network and a step of reception of a response message from each of the other devices of the network containing the autodescription information of this other device. The invention also relates to a device connectable to a network which possesses means for despatching an announcement message, containing autodescription information describing it, to all the other devices in the network, means for despatching a message for requesting autodescription information to all the other devices in the network and means for receiving the response messagescontaining information describing each of the other devices of the network.

Description

technical field [0001] The present invention relates to audio and video interoperability over networks based on network technologies other than the 1394 bus. [0002] Background technique [0003] Home Audio and Video Interoperability (HAVi stands for "Home Audio Vdeo interoperability") is a specification developed by market leading electronics companies that allows the interconnection of audio and video devices in a home environment based on a network using IEEE 1394 bus technology. The current version (version 1.1, available from HAVi, Inc. 2694 Bishop Drive, Suite 275 San Ramon, CA 94583, USA) is not designed to work on networks based on technologies other than the IEEE 1394 bus, the source of the IEEE 1394 bus It is the IEEE 1394-2000 standard. [0004] In the current context of the home equipment market, it is clear that networks developed in a home setting are often heterogeneous and involve multiple technologies other than IEEE 1394. One might have to mention the im...
