DekTec DTA-102 DVB/SPI Output Adapter


Overview

The DekTec DTA-102  DVB/SPI Output Adapter for a PCI bus can be used in a variety of video applications including an LVDS output for PC-based applications which generate an MPEG-2 transport stream.

The card has one DVB output and includes:

  • Windows 2000/XP & Linux device driver
  • API for developing custom applications
  • Example streamer code

Features

  • High-speed Transport-Stream output, compliant to DVB/SPI (Synchronous Parallel Interface) as defined in DVB document A010 rev 1 and EN50083
  • Special support for external signal adapters to e.g. ECL or TTL
  • Clock rate from 0 to 13.5 MHz with software-selectable clock source:
    • external clock input, or
    • on-board programmable clock generator
  • Short-circuit detection with bi-colour LED indicator
  • 8 MB on-board buffer
  • Hardware-assisted NULL packet insertion
  • Packet sizes supported: 130, 188, 192 and 204 bytes; arbitrary size in raw mode
  • Transmit modes for adding 16 bytes to 188-byte packets and for invalidating last 16 bytes of 204-byte packets
