Video Plex Xpress MPEG-2 Decoder

VideoPlex XPress™ is an MPEG-2 video-in-a-window decoding board designed for integration into desktop clients. Targeted at large scale video networking applications, VideoPlex XPress offers high-quality, cost effective MPEG video hardware acceleration based on the PCI Video Inlay method or the Video Port Extension (VPE - part of the PC 98 recommendations).


Fully Digital

VideoPlex XPress is a true digital component in the PC. It receives MPEG from the PCI bus and produces CCIR-656 streams. These are converted to analog for display via the Composite or S-Video output connectors or transferred through the feature connector to the VGA card. This technology gives a crystal clear image on the VGA.


Fully Compliant

Optibase DirectShow™ (ActiveMovie) filters have been successfully installed with thousands of VideoPlex boards. VideoPlex XPress benefits from the experience Optibase has gained with COM (Common Object Model) programming and support for developers and integrators. And by implementing the VPE recommendations, VideoPlex XPress benefits from wide PC industry support.


Network Oriented

Optibase has gained extensive understanding in networking, Winsock programming and MPEG over networks from working with MPEG ComMotion™ UDP, system integrators and developers and from providing end to end components. As a result, VideoPlex XPress features crucial requirements for transmitting MPEG over public networks, such as the ability to:

  • Auto-detect and recover from network errors.
  • Handle underflows.
  • Handle clock discrepancies.

Following the proven success of Optibase's VideoPlex MPEG-2 playback family, VideoPlex XPress is the best platform for creating custom video playback applications based on DirectShow™ architecture such as video-over-satellite, video server and video-over-ATM networking solutions. And by joining Progression, Optibase's developers support program, integrators can enjoy the specially developed software tools needed to develop digital video networking applications.
