2. Concerning the VA-1809
2.1 Introduction
This HDMI (High-Definition Multimedia Interface) protocol analyzer (henceforth
referred to in this manual as the VA-1809) allows the protocols required in the
development of HDMI transmitters to be checked. Its LCD screen on the front panel
enables the output images to be easily monitored, and its ability to rewrite extended
display identification data (EDID) allows various kinds of monitors to be simulated. It
comes with output HDMI connectors so that it can be used as a repeater. It can also be
used in the development and manufacture of DVD players and set-top boxes which are
equipped with HDMI connectors.
2.2 Features and main functions
■ LCD screen and VGA output connector provided
The LCD screen on the front panel enables the HDMI output images to be easily
monitored. Signals can also be output from the VGA output connector at the same
time as their images appear on the front panel LCD screen.
■ Built-in speaker and COAX OUT connector incorporated
The speaker and COAX OUT connector enable the output sound to be monitored
using methods other than HDMI. (Only linear PCM 2-channel sound can be heard
through the speaker.)
■ EDID rewriting supported
The EDID rewriting capability allows various kinds of monitors to be simulated.
■ Analyze function
This function makes it possible to check whether, for instance, the HDMI output data
complies with the HDMI standard.
■ Switching between receiver and repeater functions
Users can switch the VA-1809's functions from receiver (monitor) to repeater or vice
versa.
■ CF card data registration
This function allows the EDID contents and analysis results to be stored on CF cards
