A single-chip HDTV A/V decoder for low-cost DTV receiver

In this paper, a single chip HDTV decoder is presented which drastically cuts down the cost of a HDTV receiver. The cost reduction is achieved by integration of system demux, down-converting video decoder, and multi-mode audio decoder. System designers can also benefit from the features of our decoder which requires only 4 Mbytes of SDRAM (synchronous DRAM) for decoding the HDTV signal and various system-level functions such as the IEEE 1394 bus interface, the I/sup 2/C bus controller and the on-chip clock recovery function.
