摘要:
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.

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.

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.

According to one aspect of the disclosure, the present invention provides methods and arrangements for the removal or reduction of divergence artifacts between a transmitting codec and a receiving codec. One of a number of implementations includes using a deblocking filter in an inverse transformer loop and selectively disabling the filter upon certain conditions.

According to an example embodiment, the present invention is directed to a video communication system having a user-friendly, intuitive-like control for altering the video camera view at a remote terminal. The local terminal includes a display and a movement-responsive sensor arranged to generate a direction signal in response to corresponding movement at the display. At least one of the first and second computer arrangements is configured and arranged to alter data being sent to the display in response to the direction signal from the movement-responsive sensor.
摘要:
A video unit provides remote activation of appliances and is capable of recording locally captured video data. The video unit includes an infrared transmitter that generates infrared signals to activate and/or control appliances in response to control codes, e.g. received from a remote site by the video arrangement. The video unit also includes a storage element so that locally captured video data can be stored and played back from a remote location.
