Abstract
Abstract An information transmission system in which an information signal supplied from a base station (1) is automatically edited at relay stations (2) and retransmitted to terminal stations (5) according to a retransmission schedule assigned to each relay station (2). The transmission schedule is transmitted together with the information signal from the base station (1) to the relay station (2) which in turn records portions of the information signal directed to the station itself onto a rewritable recording medium (e.g. an optical disk) and retransmits it to its terminal stations (5) according to the retransmission schedule.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
163 words
An information transmission system comprising: a base station for supplying an information signal carrying video information; at least one relay station for receiving and retransmitting said information signal to a plurality of terminal stations; said base station having means for producing said information signal, means for producing schedule data for retransmission, means for combining said information signal and said schedule data for retransmission into a composite signal, and a transmitter for transmitting said composite signal, and said relay station having a receiver for receiving the composite signal, extracting means for extracting said schedule data for retransmission from said composite signal, a memory for storing said schedule data for retransmission, recording medium playing means for recording said information signal contained in said composite signal into a rewritable recording medium and retrieving said information signal from said recording medium according to said schedule data for retransmission for outputting a reproduced information signal, and retransmitting means for retransmitting said reproduced information signal to said terminal stations.
Claim 2
Dependent Claim
18 words
The information transmission system of claim 1, wherein said information signal is a compression signal of weather data.
Claim 3
Dependent Claim
31 words
The information transmission system of claim 1 or 2, wherein said composite signal includes at least an address of said relay station and schedule data for retransmission for said relay station.
Claim 4
Dependent Claim
21 words
The information transmission system of claim 1 2 or 3, wherein said receiver receives said composite signal transmitted via a satellite.
Claim 5
Dependent Claim
34 words
The information transmission system of any preceding claim wherein said composite signal includes, as said information signal, schedule data for retransmission of video and audio data, and said video data includes still picture data.
Claim 6
Dependent Claim
102 words
A relay station apparatus for receiving an information signal carrying video information from a base station and retransmitting it to a plurality of terminal stations, comprising: extracting means for extracting schedule data for retransmission added to said information signal supplied from said base station; a memory for storing said schedule data for retransmission; recording medium playing means for recording said information signal into a rewritable recording medium and retrieving said information signal from said recording medium according to said schedule data for retransmission for outputting a reproduced information signal, and retransmitting means for retransmitting said reproduced information signal to said terminal stations.
Claim 7
Dependent Claim
32 words
The relay station apparatus of claim 6, wherein said retransmitting means performs a time-base expansion of said reproduced information signal and retransmits a time-base expanded reproduced information signal to said terminal stations.
Claim 8
Dependent Claim
55 words
The relay station apparatus of claim 6 or 7, wherein said apparatus receives video pickup information previously transmitted from said base station, and generates a pickup command for recording, into said rewritable recording medium, pieces of video information contained in said information signal from said base station which are designated by said video pickup information.
Claim 9
Dependent Claim
64 words
The relay station apparatus of claim 6, 7 or 8, wherein said apparatus receives video pickup information transmitted from said base station each time a piece of video information is transmitted, and generates a pickup command for recording, into said rewritable recording medium, pieces of video information contained in said information signal from said base station which are designated by said video pickup information.
