  • Transporting real time video frames over an Ethernet network
    Patent number: 8355398
    Abstract: Systems and methods for real time data processing using a switching network and multiple digital signal processors (DSPs). In an embodiment, the system includes a first digital signal processor having a video port interface, a first interface disposed between the video port interface of the first digital signal processor and a switching network, a second digital signal processor having a video port interface, and a second interface disposed between the video port interface of the second digital processor and the switching network. The first interface is configured to parse a VSYNC line of a video frame that is output from the first digital signal processor via its video port interface to generate a multiplexing table based upon which scan lines of the video frame are broken up into packets compatible with the switching network such that the packets can be transmitted over the switching network and be received by the second interface and the second digital signal processor via its video port interface.
