Advance Information
MPEG Video Decoder
CXD1930Q
Description
The CXD1930Q was developed to provide an integrat-
ed, low-cost solution for DVD player and DVB set-top-box
(STB) applications. This single chip device combines all
of the logic for handling source materials which DVD and
DVB systems require.
The CXD1930Q integrates a RISC controller and, with
nano-OS™ (Sony’s proprietary operating system), and
provides advanced trick plays (e.g. no-skipping B
reverse), robust audio-video synchronization and error
concealment features.
The CXD1930Q offers a cost-effective solution to DVD
player, DVB STB and DVD PC applications.
Features
• MPEG1 and MPEG2 (MP@ML) video decoder
• MPEG1, MPEG2 (layer I, II: 5+1 channels) and Dolby
Digital™ decoder (5+1 channels), linear PCM output
• Sub-picture decoding
• DVD, VCD, DVB demultiplexing: up to 72Mbps
• Letter box pan-scan output
• On-screen display up to 256 colors
• Teletext output
• DVD standard compliant decoder
The CXD1930Q also integrates:
• NTSC/PAL video encoder with Macrovision™ copy
protection, closed-caption, and 10-bit 6-channel DAC
• Off-chip NTSC/PAL video encoder 8-bit interface
• Off-chip host CPU interface (Hitachi SH* and Motorola
68K series CPU bus interface)
• Direct SDRAM interface of 16 bits, with a maximum
81MHz clock rate
208-Pin QFP (Plastic)
Outline of Major Features
The CXD1930Q incorporates the MPEG1/MPEG2
video decoder, MPEG1/MPEG2/Dolby Digital audio
decoder, embedded RISC controller, programmable pre-
parser for system streams, programmable display con-
troller, sub-picture decoder, configurable host-interface,
NTSC/PAL video encoder and high-quality OSD feature.
In this section, a brief overview of each distinguishing
feature of the CXD1930Q functions is described.
[1] MPEG Video Decoder
1. Decodes MPEG1 (ISO 11172-2) and MPEG2
(MP@ML) (ISO 13818-2) bit streams. The image size
of CCIR601 resolution is 720x480 pixels @30fps for
NTSC and 720x576 @25fps for PAL.
2. 2.53 frame PAL decoding, with 16Mbits SDRAM con-
figuration is supported (PAL decoding ) with high
quality AV synchronization.
3. Automatic 3:2 pull down
4. Proprietary patented error concealment by micro
code with on-chip RISC software.
5. Advanced trick play (reverse on B frames, etc.) by
micro code (on-chip RISC software).
