Processor and Demux Integration for the SoC-SBTVD

Jeffrei MoreiraJônatas RechHenrique KleinAltamiro Susin

The main goal of this paper is the integration of a transport stream demultiplexer (Demux) and a closed caption decoder to the main processor of a Set-top Box (STB) for the Brazilian Digital Television System (SBTVD). The modules were presented in a previous paper at the 25th SIM ([1]), and now the integration to the STB architecture is reported. The AMBA bus was used to connect the main processor core to the demultiplexer and other peripherals. The attachment of the decoders is briefly addressed, with an emphasis to the coupling of a closed caption decoder to the corresponding demultiplexer output and its interface with the digital video output through the system main memory. An Aeroflex Gaisler Leon3 core was used as main processor.
