CMOS LSI
LC74201E
Video CD Decoder
Preliminary
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)
