Abstract
Abstract A video information retrieval system comprises a client system having: means for issuing a search request in respect of desired video material; and means for accessing video material on the basis of a uniform resource locator (URL) and a SMPTE unique material identifier (UMID); a server system having: access to one or more databases containing metadata information relating to a plurality of video material items, a UMID associated with each video material item and at least one URL associated with each UMID; means for receiving a search request from the client system and detecting one or more video material items for which metadata information stored in at least one of the database(s) substantially corresponds to the search request; means for supplying the metadata information, the URL and the UMID relating to the one or more detected video material items to the client system; and at least one video repository having: a video storage arrangement storing video material and associated UMID data; in which the metadata, the URL and the UMID are communicated between the server and the client using a markup language having descriptors for data content.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
187 words
A video information retrieval system comprising: a client system having: means for issuing a search request in respect of desired video material;
and means for accessing video material on the basis of a uniform resource
locator (URL) and a SMPTE unique material identifier (UMID); a server system having: access to one or more databases containing metadata information
relating to a plurality of video material items, a UMID associated with
each video material item and at least one URL associated with each
UMID; means for receiving a search request from the client system and
detecting one or more video material items for which metadata
information stored in at least one of the database(s) substantially
corresponds to the search request; means for supplying the metadata information, the URL and the UMID
relating to the one or more detected video material items to the client
system; and at least one video repository having: a video storage arrangement storing video material and associated
UMID data; in which the metadata, the URL and the UMID are communicated between the
server and the client using a markup language having descriptors for data content.
Claim 2
Dependent Claim
28 words
A system according to claim 1, in which the search requests are communicated
between the server and the client using a markup language having descriptors for data
content.
Claim 3
Dependent Claim
28 words
A system according to claim 1 or claim 2, in which the database stores
metadata in a hierarchical representation using a markup language having descriptors
for data content.
Claim 4
Independent Claim
22 words
A system according to any one of claims 1 to 3, in which the markup language
is an extensible markup language (XML).
Claim 5
Independent Claim
22 words
A system according to any one of the preceding claims, in which the client and
the server communicate via http port 80.
Claim 6
Independent Claim
33 words
A system according to any one of the preceding claims, in which the server
system is operable to supply URLs to the client system for accessing the video
material in a broadcast-quality representation.
Claim 7
Independent Claim
33 words
A system according to any one of the preceding claims, in which the server
system is operable to supply URLs to the client system for accessing the video
material in a sub-broadcast-quality representation.
Claim 8
Independent Claim
39 words
A system according to any one of the preceding claims, in which the server
system is operable to supply URLs and video timecodes to the client system for
accessing single images representative of the content of the video material.
Claim 9
Independent Claim
26 words
A system according to any one of the preceding claims, in which the server, the
client and the video repository communicate via the world wide web.
Claim 10
Dependent Claim
114 words
A video information server having: access to one or more databases containing metadata information relating to a
plurality of video material items, a SMPTE unique material identifier (UMID)
associated with each video material item and a uniform resource locator (URL)
associated with each UMID; means for receiving a search request from a client system and detecting one or
more video material items for which metadata information stored in at least on of the
database(s) substantially corresponds to the search request; means for supplying the metadata information, the URL and the UMID relating
to the one or more detected video material items to the client system using a markup
language having descriptors for data content.
Claim 11
Dependent Claim
95 words
A video information retrieval client system comprising: means for issuing a search request to a video information server system in
respect of desired video material; means for receiving search results from the server system comprising at least a
uniform resource locator (URL) and a SMPTE unique material identifier (UMID); and means for accessing video data from a video repository on the basis of the URL
and the UMID data; in which the metadata, the URL and the UMID are communicated between the
server and the client using a markup language having descriptors for data content.
Claim 12
Independent Claim
170 words
A method of video information retrieval using a server system having access to
one or more databases containing metadata information relating to a plurality of video
material items, a SMPTE unique material identifier (UMID) associated with each
video material item and a URL associated with each UMID; the method comprising the steps of: a client system issuing a search request in respect of desired video material; the server system receiving the search request from the client system and
detecting one or more video material items for which metadata information stored in at
least one of the database(s) substantially corresponds to the search request; and the server system supplying the metadata information, the URL and the UMID
relating to the one or more detected video material items to the client system using a
markup language having descriptors for data content; the client system accessing video material on the basis of the uniform resource
locator (URL) from a video repository having a video storage arrangement storing
video material and associated UMID data.
