Decodes an MPEG-2 bit stream, including the MPEG-2 PES layer.
Decodes an MPEG-1 bit stream as dened in ISO IS 11172, includ-
ing the MPEG-1 system layer.
Decodes dual channel MPEG audio, Layer 1 and 2 (MUSICAM), with
additional support for low sample rate coding and data rates from 8
to 448 kbps.
Operates at image sizes up to CCIR 601 resolution 720 x 480 pixels
@ 30 fps for NTSC and 720 x 576 @ 25 fps for PAL.
Supports master or slave video timing operation.
Integrates post processing lters for image resizing.
Integrates a exible on-screen display controller.
Implements 3:2 pulldown and various wide screen modes, including
16:9 mode.
Supports up to 20 Mbps serial, or 40 Mbit/s parallel, input channel
data rate.
Supports 1-bit serial or 8-bit parallel input data formats through the
control of an external microcontroller.
Provides 8-bit Y/C output data format in interlaced or progressive
scanned mode.
Interfaces directly to LSI Logic's L64007, L64008, and L64108 trans-
port demultiplexers on the input and off-the-shelf NTSC/PAL encod-
ers on the output.
Provides a complete on-chip channel buffer and display buffer con-
trols.
Includes programmable display management.
Interfaces to an inexpensive 8-bit microcontroller for initialization,
testing and status monitoring.
Supports downloadable quantization tables through bitstream.
Provides programmable channel buffer and display buffer size.
Connects directly to commodity DRAMs.
16 Mbits of DRAM, from four 4-Mbit regular DRAMs or one 16-Mbit
SDRAM, is required for CCIR601 resolution.
