720p30 codec
– M-JPEG codec, up to 12MP
– Triple-stream encoding: 720p plus CIF
or D1 H.264, and M-JPEG simultaneous
encoding
• Embedded analytics reduce software
development time
– Motion detection
– Trip wire
– Image tracking
MG2580
Maxim’s Mobicam3 IP camera reference design uses the MG2580
codec SoC to perform multistream H.264 compression, M-JPEG
compression, analytics, AES/SHA video encryption, and Ethernet
communication functions on a single chip. The MG2580 can
compress three H.264 streams simultaneously at CIF, D1, and 720p
resolutions. Simultaneous M-JPEG video or JPEG still-image capture
is also supported.
The MG2580 includes a fully programmable audio processor and
offers support for full-duplex G.722/AAC audio with the ability to
select both sample and bit rates. The full-duplex operation enables
two-way voice communication with people at the camera location.
AES and SHA encryption are performed in dedicated hardware for
the highest performance. The ARM9™ processor in the MG2580 is not
required for audio or video encoding, allowing it to be used solely for
networking and applications.
