Abstract
Abstract A system for placing data in a format for acceptance by a general purpose communications printer, the data originally being in a format for providing a television display to news wire service subscribers, and being originally in a format composed of signals representing a succession of characters. The data is temporarily stored and then read out in segments each containing signals representing the number of characters per line in the printer output, printer control signals are inserted between segments, and the resulting composite signal is then conducted to the printer locations, where it is placed in a form which can be applied to a printer.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
223 words
A system for placing a stream of data signals representing characters arranged for a television display into a format for acceptance by a communications printer for printing out of the data with a selected number of characters per line, comprising: a data adapter member including: signal storage means composed of two memory units connected for receiving and temporarily storing successive portions of the stream of character data signals; output means; control signal generating means for generating signals required to instruct a communications printer to begin printing out a new line of characters; and control means connected to said memory units and generating means for causing successive data signal portions to be written into alternate ones of said memory units and to be read out from said memory units in alternation, each data signal stream portion being read out in successive segments to said output means, each segment containing signals representing such selected number of characters, and for supplying to said output means, during intervals between read out of successive segments, the signals required to instruct the printer to begin a new line of characters, said output means emitting signals corresponding to the signals supplied thereto; and a printer controller member connected to receive the signals emitted by said output means and to supply the information contained in those signals to a communications printer.
Claim 2
Independent Claim
223 words
A system for placing a stream of data signals representing characters arranged for a television display into a format for acceptance by a communications printer for printing out of the data with a selected number of characters per line, comprising: a data adapter member including: signal storage means composed of two memory units connected for receiving and temporarily storing successive portions of the stream of character data signals; output means; control signal generating means for generating signals required to instruct a communications printer to begin printing out a new line of characters; and control means connected to said memory units and generating means for causing successive data signal portions to be written into alternate ones of said memory units and to be read out from said memory units in alternation, each data signal stream portion being read out in successive segments to said output means, each segment containing signals representing such selected number of characters, and for supplying to said output means, during intervals between read out of successive segments, the signals required to instruct the printer to begin a new line of characters, said output means emitting signals corresponding to the signals supplied thereto; and a printer controller member connected to receive the signals emitted by said output means and to supply the information contained in those signals to a communications printer.
Claim 3
Dependent Claim
33 words
An arrangement as defined in claim 1 wherein said control means are arranged to permit read out from one memory unit to occur in time coincidence with write-in to the other memory unit.
Claim 4
Dependent Claim
44 words
An arrangement as defined in claim 1 wherein each character is defined by a multi-bit binary word and the stream of data signals delivered to said system is in the form of a carrier oscillation frequency modulated with the bits of such binary words.
Claim 5
Dependent Claim
58 words
An arrangement as defined in claim 3 wherein said data adapter member further comprises demodulator means connected for demodulating the data signals delivered to said system and for conducting the demodulated signals to said signal storage means, and said output means include modulator means connected for frequency modulating a carrier with the signals delivered to said output means.
Claim 6
Dependent Claim
34 words
An arrangement as defined in claim 4 wherein the modulating frequencies imposed on the carrier by said modulating means are different from the modulating frequencies of the modulated carrier oscillation delivered to said system.
Claim 7
Dependent Claim
89 words
An arrangement as defined in claim 1 in combination with a CATV installation including a main transmitting station, at least one subscriber location equipped with an electronically controllable printer, and a closed circuit signal transmission medium connecting said transmitting station to said location, and wherein said data adapter is located at said transmitting station and connected for applying the signals emitted by said output means to said transmission medium, and said printer controller member is connected to said transmission medium to receive the signals emitted by said output means.
Claim 8
Dependent Claim
65 words
An arrangement as defined in claim 6 wherein the stream of data signals delivered to said system are from a first information source and are time multiplexed with additional data signals from a second information source, and said data adapter member further comprises signal separating means connected for conducting to said signal storage means only the stream of data signals from the first information source.
Claim 9
Dependent Claim
30 words
An arrangement as defined in claim 6 further comprising means connected to deliver the signals arranged for a television display to said transmission medium for delivery to said subscriber location.
Claim 10
Dependent Claim
44 words
An arrangement as defined in claim 6 wherein each character is defined by a multi-bit binary word and the stream of data signals delivered to said system is in the form of a carrier oscillation frequency modulated with the bits of such binary words.
Claim 11
Dependent Claim
58 words
An arrangement as defined in claim 9 wherein said data adapter member further comprises demodulator means connected for demodulating the data signals delivered to said system and for conducting the demodulated signals to said signal storage means, and said output means include modulator means connected for frequency modulating a carrier with the signals delivered to said output means.
Claim 12
Dependent Claim
34 words
An arrangement as defined in claim 10 wherein the modulating frequencies imposed on the carrier by said modulating means are different from the modulating frequencies of the modulated carrier oscillation delivered to said system.
