摘要： Aspects of the invention are directed to a telephony system that is adapted to receive, route, process, and deliver communications data using a cost-effective, user-friendly operations platform and a broadband communication network. For example, the system includes a computer server arrangement and a plurality of endpoint devices communicatively coupled to one or more communication channels comprising an Internet protocol (IP) network. Packet-based (VoIP) calls are transmitted over an IP network, and translated to standard PSTN call signals when necessary. The broadband telephony system of the present invention utilizes each user's own IP network endpoint device as not only each user's local gateway onto the IP network, but also as a remote gateway for bridging other user's calls from the IP network to a local PSTN network in order to reach non-users.

摘要： A multimedia processor contains a general purpose RISC and video processors which operate in parallel to execute software for combined video and audio bit stream coding and decoding. The RISC processor controls operation of the multimedia processor and performs bit stream parsing and coding, audio compression and decompression, and general processing for embedded applications. The video processor performs video encoding and decoding functions such as scaling, filtering, decimation, and DCT transforms. The RISC processor and the video processor each have separate data buses which are interconnected through a portal circuit and a Huffman codec. Each data bus has a DMA controller which transfers data to and from a memory interface to an external memory. DMA channels serve I/O interface resources coupled to the data buses and can form buffers in the external memory. This reduces the need for on-chip FIFO buffers and separate buffers between the multimedia processor and attached devices.

摘要： 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.

摘要： A programmable motion estimator includes one dual ported memory for storing an image block, the prediction error, and a temporary block used in interpolation, and a pixel-group random access dual ported memory for storing a search window. The two ports of the two memories are selectively applied to an arithmetic logic unit, or ALU, through a multiplexer. One output of the ALU provides an absolute difference, which is furnished to a tree adder. Another output of the ALU provides an average value or a difference value, as selected, which is routed to the inputs of the image memory and the search memory. In motion vector searching, the ALU performs pixel absolute difference arithmetic using the pixel groups from the image memory and from the search memory, and determines a sum of absolute differences in the tree adder. In half pixel interpolation, the ALU performs pixel averaging arithmetic using pixel groups from the search memory, and writes back to the search memory. In quarter pixel interpolation, the ACU performs pixel averaging arithmetic using pixel groups from the image and search memories, and writes back to the search memory. In some quarter pixel interpolations, temporary interpolated blocks from the image memory are used to interpolated quarter pixel blocks. These temporary blocks are obtained by pixel averaging in the ALU using pixel groups from the search memory. In error prediction determination, the ALU performs pixel subtraction using the pixel groups from the image memory and from the search memory, and writes back to the image memory.

摘要： A video conferencing arrangement that includes paired and configurable one-way translators. Each one-way translator is configurable to translate encoded video data from a first format to a second format, and are inter-coupled with a switch arrangement. Because each translator is configurable, a one-way translator can translate encoded video data from one of various formats to another format. Because each translator only translates from a first format to a second format, and not from the second format to the first format, conventional hardware and software can be used to save costs.
摘要翻译： 视频会议安排，包括配对和可配置的单向翻译。 每个单向转换器可配置为将编码视频数据从第一格式转换为第二格式，并且与交换机布置相互耦合。 因为每个翻译器是可配置的，所以单向翻译器可以将编码的视频数据从各种格式之一翻译成另一格式。 因为每个翻译器仅从第一格式转换成第二格式，而不是从第二格式转换为第一格式，因此可以使用传统的硬件和软件来节省成本。
