Abstract
Abstract Multi-media documents, in the form of digital signals, are fed into a multiplexer/coder by several sub-channels, which are time multiplexed. A control signal is added and the combined signal is modulated into a transmission signal at the transmitter side. At the receiver side, the transmission signal is processed up to the output of a tuner like a normal signal for television. After the tuner, the signal is demodulated, digitized, demultiplexed, and the control information of the control signal is extracted from the bit stream so that by monitoring said control information signal provided with the transmission, a transmission channel decoder enables a multi-media player to read a distributed document according to the program of the user. Alternately, the signal is directly stored by a multi-media player and the stored signal is demodulated, digitized, demultiplexed and the control information of the control signal is extracted from the bit stream so that by monitoring the control information signal provided with the transmission, a transmission channel decoder controls a reproduction device for reproducing a distributed document according to the programming of the user.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
138 words
A method for distribution of multi-media documents comprising the following steps: said multi-media documents in the form of digital signals one of said signals is demodulated, digitized, demultiplexed and control information of a digital control signal is extracted from the bit stream so that by monitoring said control information signal provided with the signal, a transmission channel decoder causes a multi-media player to record a distributed document according to the programming of the user, and said signal is directly stored by a multi-media player and said stored signal is demodulated, digitized, demultiplexed and the control information of the control signal is extracted from the bit stream so that by monitoring said control information signal provided with the transmission, a transmission channel decoder causes a reproduction device for reproducing a distributed document according to the programming of the user.
Claim 2
Independent Claim
138 words
A method for distribution of multi-media documents comprising the following steps: said multi-media documents in the form of digital signals one of said signals is demodulated, digitized, demultiplexed and control information of a digital control signal is extracted from the bit stream so that by monitoring said control information signal provided with the signal, a transmission channel decoder causes a multi-media player to record a distributed document according to the programming of the user, and said signal is directly stored by a multi-media player and said stored signal is demodulated, digitized, demultiplexed and the control information of the control signal is extracted from the bit stream so that by monitoring said control information signal provided with the transmission, a transmission channel decoder causes a reproduction device for reproducing a distributed document according to the programming of the user.
Claim 3
Dependent Claim
25 words
The method according to claim 1 wherein said multi-media player is adapted for use as a CD-I-Player and uses the recordable nature of the Magneto-Opitical-Disc.
Claim 4
Dependent Claim
18 words
The method according to claim 1 wherein said multi-media player is adapted for use in Electronic Press Applications.
Claim 5
Dependent Claim
26 words
The method according to claim 1 wherein said multi-media player is adapted for use with one of a television receiver, a radio receiver and a computer.
Claim 6
Independent Claim
98 words
A system for distribution of multimedia documents in the form of representative digital signals, comprising: one of means for demodulating a digital control signal and deriving control information from the bit stream of the control signal to enable a multi-media player to record a distributed document according to the programming by the user, and means for storing said control signal by a multi-media player and demodulating said stored signal to derive the control information from the bit stream of the control signal, to enable a reproduction device to reproduce the distributed document according to programming by the user.
Claim 7
Independent Claim
98 words
A system for distribution of multimedia documents in the form of representative digital signals, comprising: one of means for demodulating a digital control signal and deriving control information from the bit stream of the control signal to enable a multi-media player to record a distributed document according to the programming by the user, and means for storing said control signal by a multi-media player and demodulating said stored signal to derive the control information from the bit stream of the control signal, to enable a reproduction device to reproduce the distributed document according to programming by the user.
Claim 8
Dependent Claim
22 words
The system according to claim 5 wherein said multi-media player is used as a CD Player and uses a recordable magneto-optical disc.
Claim 9
Dependent Claim
17 words
The system according to claim 5 said multi-media player is adapted for use in Electronic Press Applications.
Claim 10
Dependent Claim
25 words
