Video TTY device and method for videoconferencing
First Claim
1. A video communications device for use in a video-conferencing arrangement having communication terminals in communicating over a communications channel, comprising:
- a camera for capturing local images and for generating a set of video signals representing the captured images;
a teletype device arranged to capture data input by a user and to generate a data signal representing the data input by the user;
means for alerting a user of a device-status change; and
a processor-based circuit constructed and arranged to send teletype, video data representing the captured local images, and audio data signals over the communications channel and having a program that, when executed, causes the processor-based circuit to perform the following steps;
detect a request for a video-conferencing call; and
send an output signal to activate the indicator.

Abstract
A video communications device used as part of a communication terminal in a video-conferencing arrangement provides the capability of real-time captioning along with real-time visual communication for the individuals with impaired hearing and others whose speech is not understandable or non-existent. The device enhances the ability of people with communication disabilities to communicate quickly and effectively with those who are similarly afflicted as well as with those who are not. The video communications device includes a camera and a teletype device (TTY) for transmitting and receiving teletype information. The camera captures local images and generates a set of video signals representing those images. A teletype device captures input data from a user and generates a set of data signals. The device can be configured for compatibility with conventional equipment and for alerting users of incoming calls nonaudibly.

25. A video communications device for use in a video-conferencing arrangement having communication terminals in communicating over a communications channel, comprising:
-
a camera for capturing local images and for generating a set of video signals representing those images; a teletype device arranged to capture data input by a user and to generate a set of data signals representing the data input by the user; and a processor-based circuit constructed and arranged to send teletype, video data representing the captured local images, and audio data signals over the communications channel and having a program that, when executed, causes the processor-based circuit to respond to either a mute-type command, or a detection of decreased audio input, by increasing video resolution for video data sent over the communication. - View Dependent Claims (26)

27. A method for video-conferencing between communication terminals over a communications channel, comprising:
-
capturing local images and generating a set of video signals representing the images; using a teletype device to capture user-input data and generating a set of data signals representing the user-generated data; and multiplexing the set of data signals, the video data and audio data signals over the communications channel and, using a processor-based circuit, executing a program to cause the processor-based circuit to respond to either a mute-type command, or a detection of decreased audio input, by increasing video resolution for video data sent over the communication channel.

28. A method for video-conferencing between communication terminals over a communications channel, comprising:
-
capturing local images and for generating a set of video signals representing those images; using a teletype device to capture user-input data and generating a set of data signals representing the user-generated data; multiplexing and sending data information, including the set of data signals, the video data and audio data signals, over the communications channel, the data information including a request to initiate a video-conferencing call; and using a processor-based circuit, executing a program to cause the processor-based circuit to detect the request to initiate the video-conferencing call and provide an indication thereof to a user.

29. A video communications device for use in a video-conferencing arrangement having communication terminals in communicating over a communications channel, comprising:
-
a camera for capturing local images and for generating a set of video signals representing those images; a teletype device arranged to capture data input by a user and to generate a set of data signals representing the data input by the user; and a processor-based circuit constructed and arranged to send teletype, video data representing the captured local images, and audio data signals over the communications channel and having a program that, when executed, causes the processor-based circuit to perform the following steps;
transmitting teletype information over the channel using a relatively low bit-rate;
indicating that the video communications device has a teletype capability using an extension field of an existing data communication sequence; and
recognizing that another video communications device has a teletype capability by examining an extension field of the existing data communication sequence.
