  • Patent number: 9237240
    Abstract: A method and a system for detecting presence of an application layer gateway (ALG) in a network path between an analog telephone adapter and a communications service provider (CSP), and transmitting a media message by bypassing the (ALG) are provided. A communication management application (CMA) detects, processes, and augments the media message sent by a first user device to a second user device. A message relay server (MRS) processes and manages the media message. The CMA receives the media message from the first user device and detects the presence of the ALG using a message echo server. The CMA scrambles the media message and transmits the scrambled media message to the MRS via a network. The ALG is bypassed due to non-recognition of the scrambled media message. The MRS unscrambles the scrambled media message and transmits the unscrambled media message to the CSP for forwarding to the second user device.

  • Publication number: 20150117622
    Abstract: A computer implemented method and system for bridging an analog telephone service to multiple network and telephony services (NTSs) provides a multi-service analog telephone adapter (MSATA) with software components and physical communication ports (PCPs). The PCPs establish a communication link to simultaneously access the NTSs implementing communications protocols, and receive user inputs from user devices in a voice mode or a data mode. The software components include a control engine for selectively routing and bridging a call to one or more NTSs based on the user inputs and predetermined criteria, a voice communication engine for accessing a voice communication service, a notification engine for generating and transmitting notifications, and a device management client engine, in communication with a device management server (DMS), for providing remote access to the MSATA for configuring parameters associated with the MSATA and the user devices.

  • Patent number: 6965644
    Abstract: 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.

  • Publication number: 20040207725
    Abstract: A vision processor includes a control section, a motion estimation section, and a discrete cosine transform (“DCT”) section. The motion estimation section includes two memories, an image memory with two read ports and a write port, and a search memory with two read ports and a write port. The DCT section includes a DCT memory configurable as a two read, two write port memory and as a four read, four write port memory. The ports of these memories are selectively applied to various elements in the motion estimation path and the DCT path. In motion vector searching, the ALU performs averaging and difference operations on pixels in the frame and search memories. Data from the search memory is shifted for certain operations, before arithmetic operations in the ALU are performed.
