Abstract
A method and apparatus for wideband voice and optional data conferencing over a telecommunications network channel between at least two wideband communications devices. An exemplary method comprises establishing an audio link, verifying wideband capability between the at least two wideband communications devices, training modems of the at least two wideband communications device to line conditions, and adjusting the telecommunications connection line conditions between the communications devices. Once a wideband connection has been established, audio and data may be simultaneously exchanged.
Claims30
A method for wideband conferencing, comprising:
- verifying whether at least two communications devices are wideband capable;
- establishing a connection between the at least two communications devices;
- obtaining and digitizing audio signals at a wideband communications device;
- and
- transmitting the digitized audio signals over the connection from the wideband communications devices to at least one receiving wideband communications device.
A wideband communications device for conducting a wideband conference, comprising:
- a microphone for obtaining audio from at least one conference participant;
- at least one codec coupled to the microphone for digitizing the received audio;
- and
- a modem coupled to a codec of the at least one codec for modulating the digitized audio for transmission to at least one receiving wideband communications device.
A method for establishing a conference connection between two communications devices, comprising:
- establishing an audio link between the two communications devices;
- receiving a signal at a first device of the two communications devices indicating whether a second device of the two communications device is wideband capable;
- entering a connection mode based on the received signal;
- and
- establishing the conference connection based on the connection mode.
A system for wideband conferencing, comprising:
- means for verifying whether at least two communications devices are wideband capable;
- means for establishing a connection between the at least two communications devices;
- means for obtaining and digitizing audio signals at a wideband communications device;
- and
- means for transmitting the digitized audio signals over the connection from the wideband communications devices to at least one receiving wideband communications device.
A system for establishing a conference connection between two communications devices, comprising:
- means for establishing an audio link between the two communications devices;
- means for receiving a signal at a first device of the two communications devices indicating whether a second device of the two communications device is wideband capable;
- means for entering a connection mode based on the received signal;
- and
- means for establishing the conference connection based on the connection mode.
A computer readable medium having embodied thereon a program, the program being executable by a machine to perform method steps for wideband conferencing, the method steps comprising:
- verifying whether at least two communications devices are wideband capable;
- establishing a connection between the at least two communications devices;
- obtaining and digitizing audio signals at a wideband communications device;
- and
- transmitting the digitized audio signals over the connection from the wideband communications devices to at least one receiving wideband communications device.
