Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
117 words
Information provider apparatus, comprising: a video server for transmitting video information via a forward channel and receiving information page requests via a back channel; and a computer, coupled to said video server and a TCP/IP network, for retrieving information pages from said TCP/IP network, converting the retrieved information pages into a video signal, and coupling the video signal to the video server; said computer comprising: a controller, for retrieving said information pages from said TCP/IP network in response to a control signal; a parser, coupled to said controller, for extracting hypertext information from said retrieved video page; and a menu generator, coupled to said parser, for generating a menu structure in response to said extracted hypertext information.
Claim 2
Dependent Claim
117 words
Information provider apparatus, comprising: a video server for transmitting video information via a forward channel and receiving information page requests via a back channel; and a computer, coupled to said video server and a TCP/IP network, for retrieving information pages from said TCP/IP network, converting the retrieved information pages into a video signal, and coupling the video signal to the video server; said computer comprising: a controller, for retrieving said information pages from said TCP/IP network in response to a control signal; a parser, coupled to said controller, for extracting hypertext information from said retrieved video page; and a menu generator, coupled to said parser, for generating a menu structure in response to said extracted hypertext information.
Claim 3
Dependent Claim
57 words
The apparatus of claim 1 , wherein said computer further comprises: a video compiler, coupled to said controller, for converting said retrieved information page into a page video signal; and a combiner, coupled to said video compiler and said menu generator, for combining said page video signal and said menu video signal into an output video signal.
Claim 4
Dependent Claim
23 words
The apparatus of claim 1 , further comprising: a page store unit, coupled to said computer, for storing a plurality of information pages.
Claim 5
Dependent Claim
43 words
The apparatus of claim 3 , wherein said page store unit comprises at least one of: an HTML storage unit, for storing said information pages in an HTML format; and a video storage unit, for storing said information pages in a video format.
Claim 6
Dependent Claim
57 words
The apparatus of claim 3 , wherein: said page store unit controller, in response to hypertext information included within a requested information page, retrieves additional information pages, said additional information pages being associated with said included hypertext information; and said controller, upon retrieving said additionally information pages, stores said additional information pages within said page store unit.
Claim 7
Independent Claim
120 words
A method of interactively distributing information to a subscriber comprising the steps of: receiving an information page request from said subscriber, said information page request including an internet protocol address; retrieving said requested information page from an information source; parsing said retrieved information page to identify static information structures forming said retrieved information page, said static information structures comprising graphic structures, text structures or hypertext structures; generating first video information representative of said retrieved information page; generating second video information, including menu information, representative of hypertext information structures included within said retrieved information page; combining said first and second video information to form said video information stream; and providing said video information stream to said subscriber via an information channel.
Claim 8
Independent Claim
120 words
A method of interactively distributing information to a subscriber comprising the steps of: receiving an information page request from said subscriber, said information page request including an internet protocol address; retrieving said requested information page from an information source; parsing said retrieved information page to identify static information structures forming said retrieved information page, said static information structures comprising graphic structures, text structures or hypertext structures; generating first video information representative of said retrieved information page; generating second video information, including menu information, representative of hypertext information structures included within said retrieved information page; combining said first and second video information to form said video information stream; and providing said video information stream to said subscriber via an information channel.
Claim 9
Dependent Claim
81 words
The method of claim 6 , wherein: said step of parsing also identifies dynamic information structures forming said retrieved information page, said dynamic information structures comprising applets or moving images; said step of generating first video information includes the step of incorporating said dynamic information structures within said first video information; and said steps of generating first video information, combining said first and second video information, and compressing said video information are repeated substantially in accordance with said dynamic information structures.
Claim 10
Dependent Claim
43 words
The method of claim 6 , further comprising the steps of: retrieving one or more information pages associated with said parsed hypertext information structures; and storing, in a server memory, said one or more information pages associated with said parsed hypertext information structures.
Claim 11
Independent Claim
95 words
A method for provide-side generation of a menu structure for use in an interactive video distribution system comprising provider equipment and limited capability subscriber equipment, comprising the steps of: retrieving, from a TCP/IP network, a particular information page in response to a subscriber request; parsing the retrieved information page to identify hypertext-like information structures; generating a menu structure in response to said identified hypertext-like information structures; merging, into a single video stream, the retrieved information page and the generated menu structure; and transmitting, to said subscriber equipment via a forward channel, said merged video stream.
Claim 12
Independent Claim
95 words
A method for provide-side generation of a menu structure for use in an interactive video distribution system comprising provider equipment and limited capability subscriber equipment, comprising the steps of: retrieving, from a TCP/IP network, a particular information page in response to a subscriber request; parsing the retrieved information page to identify hypertext-like information structures; generating a menu structure in response to said identified hypertext-like information structures; merging, into a single video stream, the retrieved information page and the generated menu structure; and transmitting, to said subscriber equipment via a forward channel, said merged video stream.
Claim 13
Dependent Claim
50 words
The method of claim 9 , wherein said subscriber equipment comprises a set top terminal, said set top terminal generating, in response to a user input signal, said information page request, and generating, in response to said received video signal, an output signal suitable for use by a display device.
Claim 14
Dependent Claim
20 words
The method of claim 9 , wherein said video signal carried by said forward channel is a compressed video signal.
Claim 15
Dependent Claim
19 words
The apparatus of claim 1 , wherein said video information carried by said forward channel comprises compressed video information.
Claim 16
Dependent Claim
35 words
The apparatus of claim 1 , wherein said apparatus receives requests for information from subscriber equipment via a back channel, said requested information pages being transmitted to said requesting subscriber equipment via said forward channel.
Claim 17
Dependent Claim
41 words
The apparatus of claim 13 , wherein said subscriber equipment generates, in response to a user input signal, said information page requests and generates, in response to said received video information, an output signal suitable for use by a display device.
