Abstract	This paper presents an MPEG-4 AAC decoder described in VHDL language and compliant with the Brazilian Digital Television standard (SBTVD). It has been synthesized to an Altera Cyclone II 2C35 FPGA using 26549 logic elements and 248704 memory bits. The implemented architecture has been verified using an Altera DE2 prototyping board, being capable of decoding stereo signals coded as MPEG-4 AAC Low Complexity audio objects. The minimum operating frequency required for real time decoding of a stereo audio stream with a sampling rate of 48 kHz is 4 MHz and the implemented decoder is capable of running at 56 MHz, meeting the requirements. This decoder design is intended to be integrated with a system on chip for the SBTVD set-top box.
