STORAGE CAPABILITY QUERY FOR UPNP AV MEDIA SERVER CDS |
摘要 |
A system and method for determining the remaining free storage capacity of a media database in a media server device (MSD), such as one used in a universal plug and play audio-visual (UPnP AV) architecture. The present invention allows a user of a MSD hosting a content directory service (CDS), prior to a large copy or move operation, to query the media database of the MSD as to the remaining free storage capacity. In one embodiment of the present invention, a query action is implemented in a control point (CP), allowing the CP to query the CDS, which in turn queries the MSD file system/operating system (OS) to determine the remaining free capacity storage of the media database. This capacity information is then sent back to the CP for presentation to a user of the MSD. In a second embodiment, the query is implemented as a dedicated AV MSD service. In a third embodiment, UPnP eventing and a new state variable capable of indicating the remaining free storage capacity is used.
