The H264-ULL-SD4 is an ultra low latency, quad channel, H.264 encoder on a single PCI/104 form factor board. The H264-ULL-SD4 provides a powerful and flexible solution for capturing and compressing up to 4 analog video inputs at full size and at full frame rate to the H.264/MPEG-4 AVC (Part 10) standard.

In addition to the ultra low latency full frame rate encoding of four NTSC/PAL analog video sources, the H264-ULL-SD4 also supports stream duplication to provide multiple encodings of the same input. This allows streams to be created at different resolution, compression settings dependent on requirements and available bandwidth.

The high performance H.264 video compression and efficient bus utilization allows up to four H264-ULL-SD4 to be fitted in a PCI/104 system.

 

Highlights

  • Real time 4x full size H.264 encode at full frame rate
  • Composite NTSC/PAL/RS-170 video input
  • H.264/MPEG-4 AVC (Part 10) encoder
  • Ultra Low Latency technology with a latency below 40ms (ULL H.264 compression)
  • Intra-refresh to improve bandwidth utilization
  • Multiple encodes of same input with different settings
  • Motion detection
  • Video Masking
  • Remote monitoring and control
  • PCI/104 form factor
  • Drivers for WinXP-E and Linux

Software Development Kits

The H264-ULL-SD4 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, Linux and QNX environments and include support libraries, drivers and example applications to help developers fully utilize the H264-ULL-SD4 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 SDK's suitable for PC/104-Plus based PowerPC and ARM platforms. Please contact our sales team to discuss your requirements.
