RT-AV200 Description

RT-AV200 Grabber/Generator device is a hardware system which provides test bed for automated testing of AV and multimedia systems in consumer electronic, such as TV, STB, PVR and other similar devices. The purpose of the BBT2 device is to provide automatic testing procedure for IC testing during final stage of production process, but open to serve as pattern generator or with extension boards, as TV system tester with several possible video/audio interfaces.

RT-AV200 Generator/Grabber module provides basic functionality:

  • Open architecture for fast prototyping of test-bed for different systems
  • Support for different type of Input/Output video and audio signals
  • Support for different sort of Test Platform

The device can be use as stand alone device or as a part of Automated Black Box Testing system.

Grabber module

Used as stand alone device or by automatic test tool application to capture and store image or images on local storage memory and transfer picture from local memory to host PC using USB connection. Also BBT2 device can be used for transfer or convert input signal to output adaptation board. BBT2 device provide USB 2.0 connection to host PC and it is visible like a mass storage device.

Generator module

Responsible for generation and transfer of images and video sequence stored on internal flash memory or received from host PC using USB connection to Device under Test (DUT).

Grabber + Generator

In this operation mode grab and generator operations are executed in parallel. In this mode, for example, predefined pattern will be generated and send to DUT (Device under Test), and in same time DUT output will be captured and transfer to host PC.

RT-AV200 Specifications

System Architecture

Base board:

  • FPGA - Virtex4 family
  • Single board computer – Intel PXA
  • DDRII memory
  • USB 2.0 hub
  • Audio inputs and outputs connectors
  • Video inputs and outputs connectors
  • User interface connector
  • TFT LCD interface connector

Video input and output extension boards:

There is several types of video interfaces implemented on the extension boards: LVDS, DVI, HDMI, ITU BT-656, CVBS, XVGA.
Combinations of different input and output board types are possible.
All signals should pass thru FPGA chip (conversion purpose).

Audio input and output extension boards:

  • ADC/DAC provides analog stereo system input and output (Stereo Audio, 24-bit, 96kHz, Multi-bit Sigma Delta ADC and Stereo 24-Bit, 192KHz, Multibit Sigma Delta DAC),
  • I2S standard 4 signals interface to FPGA (in and out)
  • S/PDIF (in and out)

Front panel user interface consisting keyboard and LED indication. Optional control TFT LCD display and speaker.

Power supply integrated in platform cover with passive cooling. Main power supply 220VAC connection; open frame (or framed) AC/DC converter 220VAC/12VDC, compliant with EMI/EMC and safety standards.

Video Extension Board

LVDS

LVDS video extension boards is made as single, dual or quad, 50 to 120Hz and 6 to 12 bits wide color LVDS to LVTTL/CMOS RGB (and vice versa) converters.

DVI

  • DVI 1.0 standard is used.
  • Supports 1080p and 12-bit color.
  • Support 8-bit, 10-bit, 12-bit, 16-bit per color encoding.
  • Supports HDTV resolution (720p/1080i/1080p).
  • Converting digital RBG to DVI. Supports 25 MHz – 225 MHz bandwidth.
  • Maximum resolution: QXGA (2048 x 1536).

HDMI

Standard which is used as part of HDMI 1.3 standard is DVI 1.0. So we can use specification from DVI part for converting video signal.

CVBS and XVGA

  • Converting NTSC, PAL, SECAM, and analog RGB to digital RGB, 12-bit and 24-bit RGB digital output, 12 input channels, internal anti-alias filters. 525p/625p – component progressive scan support.
  • Converting digital RGB to CVBS, S-video or analog RGB. Digital RGB 3x10-bit 4:4:4 input format. 12-bit DAC on output.
