Overview
The LC74201E is a CMOS LSI that reduces the signal
processing functions required of a video CD decoder to a
single chip. All that it takes to make a version 1 or version
2 video CD player is the addition of a CD digital signal
processor, DRAM, an audio D/A converter, digital video
encoder, and similar components.
Features
Incorporation of virtually almost all the functionality
required by a video CD player from the CD-ROM
decoder through to the MPEG audio and video decoders
in a single chip
Fully automatic playback with automatic decoding
within the LSI in response to simple external commands
and the MPEG bit stream
Special playback functions are activated by command
inputs, and do not require signal processing by the host
microcomputer
Support for two external DRAM configurations:
4 M bits (256k
×
16 bits) or 4 M bits (256k
×
16 bits) +
1 M bit (64k
×
16 bits)
Support for a Track 1 DRAM user area (i.e., sector
buffer) of up to 8 k bytes (4 M bits of external DRAM)
or 22 k bytes (5 M bits of external DRAM)
Automatic synchronization of audio and video
Built-in high-speed decoder core that supports variable-
speed video playback at up to quadruple speed. Audio
support for normal and double-speed playback.
Internal registers that offer configuration settings for
connecting to most commercially available CD digital
signal processors and D/A converters
Compatible with version 2 of the video CD standard.
Support for superimposition of closed caption data on
the output signal as specified in the EIA608 standard
Support for Photo CD standard. (Base/4 and Base/16)
