Battery-Operated Smart Home
Monitoring Camera Applications
The OV798 is a highly integrated, low power and fast boot up
camera video processor aimed at battery-operated, smart
home monitoring camera applications. The OV798 reduces
system integration cost with more embedded image processing
functions, as well as more embedded peripherals. It also
supports various types of DDR SDRAM in order to
accommodate power/speed requirements for different
applications. The OV798 runs efficiently and consumes low
power. A sophisticated boot up mechanism wakes up the
OV798 quickly and starts recording video once it is triggered.
The OV798 implements an advanced video engine to achieve
high performance video recording at up to 1080p resolution.
The engine is capable of recording dual video streams of up to
one 1080p video stream and one 720p video stream. Along
with an embedded audio engine and depending on audio
formats, the OV798 also records and decodes the audio
stream.
The OV798 supports three camera interfaces. It supports a
MIPI receiver, a dedicated DVP input port, and a shared DVP
input port. The MIPI receiver can be configured as four singlelane receivers, two dual-lane receivers, or one 4-lane receiver.
The OV798 combines various parallel and serial peripheral
interfaces including a storage card interface, serial interface,
serial audio interface, SCCB interface, UART interface, DDRSDRAM interface, and USB device and host interfaces with
embedded PHY.
The OV798 has an embedded advanced image signal processor
(ISP) that supports 1080p full HD video or still pictures of up to
16 megapixels. In addition to RGB raw image sensors, the ISP
also supports RGB-Ir and HDR image sensors.
The OV798 supports a 2-lane MIPI transmitter, DVP output, or
BT1120 output.
