SONY CXD1922Q

CXD1922Q
MPEG-2 Video Encoder
Description
208-Pin QFP (Plastic)
The CXD1922Q is a highly-integrated device including MPEG-2 encoder, motion estimation, and system
and rate controller on a single chip. The device is ideal
for low-cost solutions in consumer products, storage
media, communications and authoring applications.
The CXD1922Q supports MPEG-2 [email protected] encoding
compliant with ISO/IEC 13818-2 for frame structure
encoding.
Encoding Controller (Closed)
• Programmable rate and system control
• Host independent operation
• CBR and VBR encoding support
• Constant length coding for storage media
• Adaptive frame/field MC/DCT coding
• Programmable parameters including:
— Bit rate
— GOP structure (M&N value)
— Encoding image size
— Quantization matrix tables, etc.
