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 MP@ML 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. Features MPEG-2 Encoding • High quality, real-time encoding (I, B, P) • Supports MP@ML, SP@ML — Image size: up to NTSC 720x480 @ 30fps up to PAL 720x576 @ 25fps — Up to 2 “B-frame” (M ≤ 3) — Frame structure • Encoding rates: — Max. bit-rates: 15Mbps (P, B) 25Mbps (I only) • MPEG-2 Video Elementary Stream Output — 4:2:0 chroma format encoding Interfaces • Host: 16-bit controller • Input video: 4:2:2 YUV CCIR 656 (8-bit parallel) • Output video: 8-bit video elementary stream (8-bit parallel) • External memory: 32Mbits — Supports SDRAM (e.g. 512K x 16 x 2-chips) Motion Estimation • Adaptive motion estimation algorithms • Wide motion vector search range: — Horizontal: –288 to +287.5 — Vertical: –96 to +95.5 • Frame/field motion estimation • Half-pel accuracy • Dual-prime encoding support Other: • Supports MPEG-1 encoding • Multi-level temporal noise reduction • Image conversion for free size encoding • 4:2:2 to 4:2:0 video conversion • Automatic scene change detection • Automatic 3:2 pull-down inversion • Error concealment I-frame motion vectors • Support for user data insertion in encoded stream Sony reserves the right to change products and specifications without prior notice.
