This paper presents the development of a system-on-chip for the digital television set-top box compliant to the Brazilian Digital Television Standard (SBTVD). According to this system, video, audio and data information are mixed and transmitted over the same broadcasting channel and HW and SW processes running on a set-top box recover the video, audio and data information. The Brazilian system has adopted the H.264/AVC and MPEG-4/AAC standards for video and audio coding respectively. The development of hardware for such a complex system is initially focused on the development of an FPGA prototype for HD 720p intra-only video decoding, which is the more computational demanding hardware processing unit and requires more data bandwidth. It has been synthesized to a Xilinx Virtex-II Pro FPGA using 17.308 LUTs running at 50 Mhz and it was validated in a prototyping board decoding HD 720p video streams in real time. It was also implemented to standard-cells using a TSMC 0.18¼m 6 metal layers CMOS technology. As a result, it was designed an ASIC layout with 5KB of on-chip SRAM and 150K equivalent-gates in a 2.8 x 2.8 mm2 area. This implementation is capable to decode a 720p video with 30fps with a frequency of 50 MHz with an estimated power consumption of 11.4 mW and has been validated using the same video streams using Cadence, Synopsys and Mentor Graphics EDA tools. |
