Method and system for filtering home-network content
First Claim
1. A method of filtering and storing information describing characteristics of content stored on at least one network device and accessible via a network, said content being potentially useable by a plurality of network rendering devices adapted for rendering content, the method comprising the acts of:
- periodically filtering the information describing characteristics of the content to yield filtered information and remaining information, the filtered information being devoid of information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices;
storing, in a content directory, the filtered information devoid of information describing characteristics of content that cannot be rendered by any of said plurality of network rendering devices;
determining that the remaining information cannot be rendered by any of the plurality of network rendering devices for forming removed information;
storing the removed information removed by the periodically filtering act;
searching or browsing the content directory to review said filtered information devoid of information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices; and
searching the removed information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices,wherein said searching or browsing of the content directory to review said filtered information devoid of information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices, is performed independently of said periodic filtering of information about the content to yield filtered information devoid of information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices, andwherein said periodic filtering of information about the content to yield filtered information devoid of information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices, is performed upon elapse of a predetermined time interval following removal from the network of a network rendering device of the plurality of network rendering devices.

Abstract
A method for filtering and storing information about content which is available on a network device of many network devices in a network includes filtering the information by removing information about content which cannot be rendered by at least one of the network devices adapted for rendering content, storing the filtered information and making it available on the network. When the network is a UPnP network, then control points have faster reaction times when they browse a content directory that includes the stored filtered information. For reducing load on the content directory service, the control point and the network is obtained when the control point browses the content directories. Further, the content presented to the user on the user screen of a control point only comprises content which can be used.

15. A device adapted for filtering and storing information describing characteristics of content accessible via a network, said content being potentially useable by a plurality of network rendering devices adapted for rendering content, the device comprising:
-
at least one filtering element adapted to periodically filter the information describing characteristics of the content to yield filtered information and remaining information, the filtered information being devoid of information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices; and a storage element containing a content directory including the filtered information devoid of information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices; wherein the storage element further contains removed information removed by the at least one filtering element; wherein the content directory is searchable or browseable to enable review of said filtered information devoid of information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices, and searching or browsing of the content directory to review said filtered information devoid of information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices is performed independently of said periodic filtering by the at least one filtering element to yield filtered information devoid of information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices, and wherein the content directory is searchable or browseable to enable review of said removed information, and wherein said periodic filtering of information about the content to yield filtered information devoid of information describing characteristics of content that cannot be rendered by any of the plurality of network rendering devices, is performed upon elapse of a predetermined time interval following removal from the network of a network rendering device of the plurality of network rendering devices. - View Dependent Claims (16, 17, 18, 19)
