Abstract
Abstract A simultaneous voice and data (SVD) communications system includes an SVD modem at either endpoint of the system. Each SVD modem provides an SVD signal to the opposite endpoint, where this SVD signal includes both a voice channel and a data channel. One, or both, of these SVD modems allows the respective user to alter either the voice signal that is provided to that user, or the voice signal that is transmitted from that user, via the voice channel of the SVD signal, to the opposite SVD endpoint.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
95 words
A modem comprising: a data port for receiving a data signal from data terminal equipment; a voice port for receiving a voice signal from voice terminal equipment; a line port for coupling a modulated signal to a communications channel; means for selecting one of a number of sound effects; means for modifying the voice signal in accordance with the selected sound effect; means for combining the modified voice signal and the data signal to provide a combined signal; and modulation means for modulating the combined signal to provide the modulated signal to the communications channel.
Claim 2
Dependent Claim
95 words
A modem comprising: a data port for receiving a data signal from data terminal equipment; a voice port for receiving a voice signal from voice terminal equipment; a line port for coupling a modulated signal to a communications channel; means for selecting one of a number of sound effects; means for modifying the voice signal in accordance with the selected sound effect; means for combining the modified voice signal and the data signal to provide a combined signal; and modulation means for modulating the combined signal to provide the modulated signal to the communications channel.
Claim 3
Dependent Claim
16 words
The apparatus of claim 1 wherein the modulated signal is a simultaneous voice and data signal.
Claim 4
Dependent Claim
117 words
Apparatus comprising: means for encoding a data signal; means for selecting one of a number of sound effects; means responsive to the selected sound effect for encoding a voice signal to provide a modified voice signal; and means for simultaneously transmitting the modified voice signal and the encoded data signal to a remote endpoint; wherein the encoded data signal represents a sequence of data symbols, and the modified voice signal represents a sequence of voice signal points, and the means for transmitting includes means for adding the encoded data signal to the modified voice signal so that one of the sequence of voice signal points is added to a respective one of the sequence of data symbols.
Claim 5
Dependent Claim
117 words
Apparatus comprising: means for encoding a data signal; means for selecting one of a number of sound effects; means responsive to the selected sound effect for encoding a voice signal to provide a modified voice signal; and means for simultaneously transmitting the modified voice signal and the encoded data signal to a remote endpoint; wherein the encoded data signal represents a sequence of data symbols, and the modified voice signal represents a sequence of voice signal points, and the means for transmitting includes means for adding the encoded data signal to the modified voice signal so that one of the sequence of voice signal points is added to a respective one of the sequence of data symbols.
Claim 6
Dependent Claim
23 words
The apparatus of claim 3 wherein the voice signal represents a person's voice and the selected sound effect alters the person's vocal characteristics.
Claim 7
Dependent Claim
26 words
The apparatus of claim 3 wherein the voice signal represents a person's voice and the selected sound effect adds a background sound to the voice signal.
Claim 8
Dependent Claim
49 words
The apparatus of claim 3 wherein the means responsive to the selected sound effect further includes: means for modifying the voice signal in accordance with the selected sound effect to provide an output signal; and voice encoding means for encoding the output signal to provide the modified voice signal.
Claim 9
Dependent Claim
99 words
A modem comprising: a data port for providing a data signal to data terminal equipment; a voice port for providing a modified voice signal to voice terminal equipment; a line port for receiving a modulated signal from a communications channel; means for selecting one of a number of sound effects; means for demodulating the received modulated signal to provide a first signal; means for decoding the first signal to provide the data signal and a received voice signal; and means for modifying the received voice signal in accordance with the selected sound effect to provide the modified voice signal.
Claim 10
Dependent Claim
99 words
A modem comprising: a data port for providing a data signal to data terminal equipment; a voice port for providing a modified voice signal to voice terminal equipment; a line port for receiving a modulated signal from a communications channel; means for selecting one of a number of sound effects; means for demodulating the received modulated signal to provide a first signal; means for decoding the first signal to provide the data signal and a received voice signal; and means for modifying the received voice signal in accordance with the selected sound effect to provide the modified voice signal.
Claim 11
Dependent Claim
16 words
The apparatus of claim 7 wherein the modulated signal is a simultaneous voice and data signal.
Claim 12
Dependent Claim
79 words
A modem comprising: means for demodulating a received signal to provide a received data signal; means for decoding the received data signal to provide a data signal and a data symbol; means for recovering a received voice signal from the received data signal and the data symbol; means for selecting one of a number of sound effects; and means for modifying the received voice signal as a function of the selected sound effect to provide a modified voice signal.
Claim 13
Dependent Claim
79 words
A modem comprising: means for demodulating a received signal to provide a received data signal; means for decoding the received data signal to provide a data signal and a data symbol; means for recovering a received voice signal from the received data signal and the data symbol; means for selecting one of a number of sound effects; and means for modifying the received voice signal as a function of the selected sound effect to provide a modified voice signal.
Claim 14
Dependent Claim
24 words
The apparatus of claim 9 wherein the received voice signal represents a person's voice and the selected sound effect alters the person's vocal characteristics.
Claim 15
Dependent Claim
28 words
The apparatus of claim 9 wherein the received voice signal represents a person's voice and the selected sound effect adds a background sound to the received voice signal.
Claim 16
Independent Claim
77 words
A method for use in a modem, the method comprising the steps of: receiving in the modem a simultaneous voice and data signal; decoding the simultaneous voice and data signal to provide a voice signal and a data signal; providing the data signal to data terminal equipment; selecting one of a number of sound effects; modifying the voice signal as a function of the selected sound effect; and providing the modified voice signal to voice terminal equipment.
Claim 17
Independent Claim
77 words
A method for use in a modem, the method comprising the steps of: receiving in the modem a simultaneous voice and data signal; decoding the simultaneous voice and data signal to provide a voice signal and a data signal; providing the data signal to data terminal equipment; selecting one of a number of sound effects; modifying the voice signal as a function of the selected sound effect; and providing the modified voice signal to voice terminal equipment.
