The AL582 and AL360 system-on-chip (SOC) solutions for HD video streaming and conversion applications from AverLogic are available at representative and distributor L2Tek.  With just a 12 x 12mm footprint, the AL582 compact chipset delivers a cost-effective, low power and wireless H.264 video streaming solution, particularly appealing to manufacturers of professional surveillance cameras.

The device especially addresses the slow adoption of surveillance equipment by residential owners due to cost, power consumption, complex installation and maintenance.

It has a stable, well-defined interface to help developers to get products faster to market. Based around a 720p codec, the AL582 delivers scaling, de-interlacing, format conversion, video freeze, zoom, flip, mirror, rotation, motion detection among other features.

The device supports RGB888, BT.1120, YCbCr, BT.656 inputs and outputs. Additionally, it provides analogue RGB DAC and CVBS outputs.

In an equally small package, the AL360 provides a comprehensive capability for converting various video sources (including a CMOS sensor, composite video camera, PC VGA signal or HD video from a Blu-ray disc player) to outputs suitable for driving a range of displays (such as a projector, LCD monitor, CVBS TV or TV monitor).

The device implements all the scaling, interlacing, de-interlacing required to achieve this format conversion (between 640x480 to 1920x1080).

It provides for video freeze, zoom, flip, rotation, mirror and 256-colour on-screen display (OSD).
