video codec
– Flexible recording resolution up to
1920 x 1080i (p30)
– Fully programmable video resolutions
and frame rates
• Simplified multichannel system design
lowers design cost
– 4 D1 + 4 CIF encoders per MG3500 in
encoding path
– Simultaneous primary (recording) and
secondary (streaming) channel encoding
– 8 D1 decoders per MG3500 in playback
decoding path
• Integrated on-chip peripherals reduce
board size and manufacturing cost
– 10/100/Gigabit Ethernet MAC
– USB On-The-Go
– NAND/NOR/SD/SDIO/MMC/CF/CE-ATA/IDE
interfaces

MG3500
The MG3500 is a highly integrated, HD or multichannel SD, H.264
codec SoC ideally suited for the security DVR market. It offers a
fully compliant baseline, main, and high-profile HD H.264 codec;
MJPEG codec; video preprocessors and postprocessors for scaling
and compositing; 240MHz ARM9™ CPU; and a host of peripherals
including Gigabit Ethernet MAC, USB OTG, SD™ card, CompactFlash®
memory, IDE, CE-ATA, SDIO, and MMC.
