DekTec Dual ASI Output Card


The DTA-105 is a PC-based solution that featured dual ASI output channels on a low-profile PCI card. It provides fully programmable bitrate capabilities from 0-214 mbit/s and dual 16 Mbyte buffers to compensate for PCI and any software latencies.

Sencore is the preferred distributor of DekTec in North America.

  • Two independent DVB-ASI outputs channels on a low profile PCI card
  • Optional mode to slave the second output to the first, creating a single doubly buffered output
  • Programmable bitrate 0 to 214 Mbit/s
  • Dual 16Mbytes buffers to compensate for PCI and software latencies
  • Shipped with a low profile and a standard profile bracket
  • Hardware assisted null packet insertion
  • Continuous mode or burst mode
  • On board PCI Bus master for off loading host processor
  • DMA burst mode transfers for optimal useage of PCI Bus
  • Scatter/gather DMA for efficient handling of fragmented host memory
  • Low and standard profile
  • PCI bracket PCI rev 2.2, 32 bit, 33 or 66 MHz bus
  • Free drivers and SDK for current versions of Windows, .NET, DirectShow and Linux
  • Example source code for stream player and stream recorder
  • General purpose output adapter for PC based applications that generate an MPEG2 transport stream
  • With DTC-300 StreamXpress software: MPEG2 transport stream test generator
