microMPEG4-D4 – 4 Channel, Full Frame Rate MPEG-4 Codec for mini PCI

The microMPEG4-D4 is a 4 channel, full frame rate MPEG-4 Codec on a single Type-III mini PCI module. The microMPEG4-D4 provides a powerful solution for capturing and compressing analog video inputs to the MPEG-4 standard. The microMPEG4-D4 not only provides MPEG-4 compression but can also simultaneously decompress and replay recordings from storage to display.

The microMPEG4-D4 allows high quality real-time video and audio capture and compression from NTSC/PAL video sources to disk and simultaneously provides an additional path for uncompressed video for on-screen preview or optional downstream video analytics.

Highlights

Quad speed MPEG4 video codec
Up to 4 x 4CIF (704 x576) size encoding at full frame rate (for NTSC / RS-170, PAL / CCIR video signals)
MPEG4 decode playback
Composite video or s-video outputs for preview or playback
High speed text overlay (for recording path)
High speed bit mapped graphics overlay with multi-level alpha blending (for analog preview output)
Automatic detection of motion
G.723 audio codec for each input channel with single audio playback channel
Real-time video preview to system VGA or NTSC/PAL output
Drivers for Windows XP/XP-Embedded and Linux
Low power Type IIIB mini PCI form factor
Operating temperature: 0°C to +60°C or -40°C to +85°C
Software Development Kits

The microMPEG4-D4 is supported by comprehensive and well supported software development kits (SDKs) for video recording and video streaming. The SDKs are designed to significantly reduce development time in Windows and Linux environments and include support libraries, drivers and example applications to help developers fully utilize the microMPEG4-D4 features in complex video compression / overlay applications.

The standard Video Recording SDK and sample applications are supplied free of charge with each board and includes the services of our technical support team. The Video Streaming SDK is available for a one-time fee and enables real time streaming of compressed video data over an IP network.

The standard SDKs are available for x86 based embedded PC platforms however, we also offer SDKs suitable for mini PCI based ARM and PowerPC platforms. Please contact our sales team to discuss your requirements.
