Abstract

This paper describes a device capable of performing the following tasks: it samples and decodes the composite video analog TV signal, it encodes the resulting RGB data into a MPEG-4 stream and sends it over a WiMAX link. On the other end of the link a similar device receives the WiMAX signal, in either TDD or FDD mode, decodes the MPEG data and displays it on the LCD display. The device can be a hand held device, such as a mobile phone or a PDA. The algorithms for the analog TV, WiMAX physical layer, WiMAX MAC and the MPEG encoder/decoder are executed entirely in software in real time, using the Sandbridge Technologies’ low power SB3011 digital signal processor. The SB3011 multithreaded digital signal processor includes four DSP cores with eight threads each, and one ARM processor. The execution of the algorithms requires the entire four cores for the FDD mode. The WiMAX MAC is executed on the ARM processor.
