Abstract
Abstract A television system includes a central television transmitter, a relay station, a plurality of general information receivers and a plurality of special receivers. The central transmitter transmits at least fields of general user information interplexed with fields of special user information to the relay station. The relay station selects the fields of special user information for transmission to the special receivers and also substitutes for such fields adjacent fields of general user information so that a continuous stream of general user information can also be transmitted to the plurality of general information receivers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
365 words
A television transmission system comprising: a television transmitter comprising means for generating at least fields of a first class of information, means for generating at least fields of a second class of information, means for sequentially transmitting all of said fields with at least one field of said second class of information being inserted between two fields of said first class of information, means for transmitting an indicator signal related to the time of occurrence of said field of said second class of information; a television relay unit comprising means for receiving the sequentially transmitted fields of information, control means receiving said indicator signal for generating control signals, first retransmitting means for controllably retransmitting some of the received fields of information, said first retransmitting means including reconstructing means responsive to said control signals for substituting for said field of said second class of information one of the fields of said first class of information adjacent thereto so that said first retransmitting means only retransmits fields of said first class of information without interruption, said reconstructing Means comprising first and second gating means, each of said gating means having an input for the sequentially transmitted fields of information and an output, a delay means for delaying fields of information for at least one field time, said delay means having an input connected to the output of said first gating means and an output, means having inputs connected to the output of said second gating means and the output of said delay means and an output for transmitting fields of information received at either input thereof, and means responsive to said control signals for controlling the transmission states of said first and second gating means, and second retransmitting means for controllably retransmitting some of the received fields of information, said second retransmitting means including field selecting means responsive to said control signals for selecting said field of said second class of information so that said second retransmitting means only transmits fields of said second class of information; at least one receiver for receiving the fields transmitted by said second retransmitting means; and at least one further receiver for receiving the fields transmitted by said first retransmitting means.
Claim 2
Dependent Claim
365 words
A television transmission system comprising: a television transmitter comprising means for generating at least fields of a first class of information, means for generating at least fields of a second class of information, means for sequentially transmitting all of said fields with at least one field of said second class of information being inserted between two fields of said first class of information, means for transmitting an indicator signal related to the time of occurrence of said field of said second class of information; a television relay unit comprising means for receiving the sequentially transmitted fields of information, control means receiving said indicator signal for generating control signals, first retransmitting means for controllably retransmitting some of the received fields of information, said first retransmitting means including reconstructing means responsive to said control signals for substituting for said field of said second class of information one of the fields of said first class of information adjacent thereto so that said first retransmitting means only retransmits fields of said first class of information without interruption, said reconstructing Means comprising first and second gating means, each of said gating means having an input for the sequentially transmitted fields of information and an output, a delay means for delaying fields of information for at least one field time, said delay means having an input connected to the output of said first gating means and an output, means having inputs connected to the output of said second gating means and the output of said delay means and an output for transmitting fields of information received at either input thereof, and means responsive to said control signals for controlling the transmission states of said first and second gating means, and second retransmitting means for controllably retransmitting some of the received fields of information, said second retransmitting means including field selecting means responsive to said control signals for selecting said field of said second class of information so that said second retransmitting means only transmits fields of said second class of information; at least one receiver for receiving the fields transmitted by said second retransmitting means; and at least one further receiver for receiving the fields transmitted by said first retransmitting means.
Claim 3
Dependent Claim
24 words
The television system of claim 1 wherein said delay means is a magnetic disc recording reproducing system rotating in synchronism with the field rate.
Claim 4
Dependent Claim
23 words
The television system of claim 1 wherein said indicator signal occurs in the field preceding said field of said second class of information.
Claim 5
Dependent Claim
38 words
The television system of claim 3 wherein the field of said first class of information being substituted for said field of said second class of information is the field preceding said field of said second class of information.
Claim 6
Dependent Claim
340 words
A television transmission system comprising: a television transmitter comprising means for generating at least fields of a first class of information, means for generating at least fields of a second class of information, means for sequentially transmitting all of said fields with at least one field of said second class of information being inserted between two fields of said first class of information, a television relay unit comprising means for receiving the sequentially transmitted fields of information, control means for generating control signals, first retransmitting means for controllably retransmitting some of the received fields of information, said first retransmitting means including reconstructing means responsive to said control signals for substituting for said field of said second class of information one of the fields of said first class of information adjacent thereto so that said first retransmitting means only retransmits fields of said first class of information without interruption, said reconstructing means comprising first and second gating means, each of said gating means having an input for the sequentially transmitted fields of information and an output, a delay means for delaying fields of information for at least one field time, said delay means having an input connected to the output of said first gating means and an output, means having inputs connected to the output of said second gating means and the output of said delay means and an output for transmitting fields of information received at either input thereof, and means responsive to said control signals for controlling the transmission states of said first and second gating means, and second retransmitting means for controllably retransmitting some of the received fields of information, said second retransmitting means including field selecting means responsive to said control signals for selecting said field of said second class of information so that said second retransmitting means only transmits fields of said second class of information; at least one receiver for receiving the fields transmitted by said second retransmitting means; and at least one further receiver for receiving the fields transmitted by said first retransmitting means.
Claim 7
Dependent Claim
