SVCD DECODER
1. GENERAL DESCRIPTION
The SPCA718A A/V decoder is a high-performance low-cost
single-chip SVCD decoder. It performs real-time decoding and
playback of ISO/IEC 13818/11172 MPEG2/MPEG1 data stream.
The SPCA718A is extremely superior in SVCD and VCD
application system. It utilizes the least external memory to build
a complete SVCD/VCD player. In the SVCD case, it requires
only one 1Mx16 SDRAM and one 256kx8 ROM, whereas in the
VCD system, it requires only one 1Mx16 SDRAM or 256Kx16
EDO DRAM and one 256kx8 ROM. For enhanced applications it
can extend external SDRAM from 16Mbits to 128Mbits and EDO
DRAM from 4M bits to 32M bits.
A sample system utilizing the SPCA718A is presented below:

The SPCA718A combines all the functions necessary for a typical
SVCD system, such as a house-keeping RISC, efficient MPEG
audio/video decoder, DRAM controller, on screen display, an
embedded high resolution ADC and stereo key controller for
Karaoke. The SPCA718A also includes a flexible programmable
interface and allows the application engineer to further expand
SVCD functionality. With this interface, the system developer can
greatly expand SVCD system capability.
The SPCA718A is designed to connect to standard TV encoder,
audio DAC(s), and CD-DSP without glue logic.
