A multimedia communication arrangement processes and multiplexes different types of data, including data from an adaptive data rate data source and a nonadaptive data rate data source, to substantially increase data throughput over a communication channel. The rate at which data is collected from the adaptive data rate data source varies based on the available channel bandwidth of the modem. The transmission rate is optionally adjusted in response to a detected error rate. Furthermore, the amount of filtering performed by a video camera on an image before the image is encoded by a codec can be adjusted. In addition, a data recovery terminal optionally selectively adjusts intervals at which received audio data is sampled to potentially reduce latency periods.

Data processor having controlled scalable input data source and method thereof

A videophone apparatus with an on-screen telephone keypad user-interface. The videophone communicates video and audio data over a plain old telephone service (POTS) line and includes a video source and a communication channel interface circuit coupled to a programmable processor. The programmable processor is configured and arranged to execute a user interface program for user controlled operation of the videophone apparatus, display a first menu on the display, the first menu referencing a first plurality of options for operating the videophone apparatus and having associated therewith respective indicators of telephone keypad buttons, receive from the telephone keypad a first selection signal indicative of a pressed button, and initiate an operation to control the videophone apparatus in response to the first selection signal.

Videocommunicating device with an on-screen telephone keypad user-interface method and arrangement

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 that are hearing- or language-impaired 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. In one example embodiment, 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.

Video TTY device and method for videocommunication

In one embodiment, a cost-effective videophone device includes a programmable processor circuit capable of communicating over a conventional communications channel, such as a POTS line, and of generating video data for display on a television set. The device includes a video source, an interface circuit, including a modem transmitting and receiving video and audio data over the channel; an EEPROM circuit for storing a program to control the videophone apparatus; and a display driver circuit for generating video data to the display. The programmable processor circuit includes a DSP-type processor for processing video data and a RISC-type processor executing the stored program and controlling the operation of the videophone apparatus. Further, a housing arrangement, enclosing each of the above structures, mounts adustably on the top of the display.

Videocommunicating apparatus and method therefor

A cost-effective videophone includes a programmable video/general-purpose processor capable of readily updating program-related data. The processor includes a first circuit section used to process data for videoconferencing and to detect codes data used for revising software-related data provided from a remote location, and a second circuit section used for executing the executable program data stored in the second memory circuit. A volatile memory circuit is coupled to and accessed by the programmable video/general-purpose processor, and is used for storing the revision data until it is validated. Once validated, the revision data is transferred from the first memory circuit to a non-volatile memory circuit. The non-volatile memory circuit is then used by the processor in a subsequent video-related application, such as a videoconferencing application or a web browser application.

Apparatus and method for videocommunicating having programmable

Configuring a communication arrangement that transmits video and other signal types using operational modes includes constructing a hierarchy of nodes representing the operational modes. The hierarchy also includes null nodes and a root node. Scores are collected as the nodes are traversed. The score represents a difference between the operational modes represented by the nodes along the path and desired operational modes received from a data recovery terminal. When the sum of scores collected for a set of nodes exceeds a threshold, the order of traversal is reversed. Reversing the order discards inefficient solutions and avoids dedication of system resources to evaluating such solutions. In addition, decreasing the number of paths evaluated permits more rapid determination of the operational modes best matching the desired operational modes.

Arrangement for configuring a video communication system and method

A multimedia communication system processes and multiplexes different types of data, including data from an adaptive data rate data source and a nonadaptive data rate data source, to substantially increase data throughput over a communication channel. The system includes: a first data source, responsive to a control signal, including a video image processor constructed to capture images and to present the images as a first type of data at a rate determined as a function of the control signal; at least one additional data source generating at least one additional data signal; a data signal processor that determines an available bandwidth factor for the communication channel, generates the control signal in response to this factor, collects the first type of data at a rate that varies in response to the available channel bandwidth of the modem, and collects the at least one additional type of data at at least one established rate. A communication channel modem transmits the data to a receiving terminal as the data is presented by the data signal processor.
