发明名称 Method and apparatus for optimising the resource sharing for audio/video/data processing devices in a home network environment
摘要 <p>The home network environment of the present invention is the digital video broadcasting (DVB) wherein the services can be shared with respect to a Master/Slave protocol by a plurality of audio/video/data processing devices (51,52,53,54) which are for instance Set Top Units. A may have access to services that are offered to the Master STU on the same transport stream. The principles of sharing the resource is based on the Master/Slave protocol. The first STU that is connected to a DVB receiver becomes the Master of this DVB receiver. As long as there is an available DVB receiver, a STU will have access to all the services accessible by this receiver. If there are no more receivers left, a STU may have access to all the services currently viewed by the other STUs and more specifically to all the services offered on the transponder that comprises the services currently viewed by said other STUs. Thus, the method for optimising the resource consists in assigning to each STU connecting to the home network, one of the receiving means that is available, by conferring to each STU a status of Master STU; in assigning to each newly connected STU one of the receiving means that provide requested resource and conferring a status of Slave STU, when no receiving means is available; and sharing the resource between Master STUs and Slave STUs in the home network so as to provide access to the requested resource for the Slave STUs. Conversely, an apparatus for sharing the resource further comprises control means (100,200) dedicated for each STU for displaying resource that is available for the corresponding STU wherein the control means contains an indication of Slave status for resource that can be provided for the corresponding STU and a special indication for resource that is currently used by a corresponding STU. &lt;IMAGE&gt;</p>
