HD/SD Down Converter/De-embedder/Video&Audio Monitoring Module

The HDC6831N is an HD-SDI down converter de-embedding audio from an HD-SDI and a SD-SDI signal. The module supports signal conversion from an HD-SDI to a SD-SDI, an HD-SDI to analog composite video, and also from a SD-SDI to analog composite video.
When the module de-embeds from an HD-SDI and a SD-SDI, it provides 2 pairs of AES/EBU outputs and 4 channels of analog audio outputs.
The HDC6831N supports OSD, time code, video format display and 8 channels of audio metering display.

Features  >>> 

• Auto sensing HD-SDI/SD-SDI input
• Support 1080I, 1080P, 720P, 1035I, 576I, 480I format convertion
• 2 channels of reclocked HD/SD-SDI loop outputs
• 2ch down-converted SD-SDI output (for HD-SDI input) or 2ch SD-SDI output without down-converted (for SD-SDI input)
• 2 channels of CVBS outputs​
• The user can overlay OSD menu, input/output format, audio level meter and time code to the SD-SDI/CVBS output
• HD to SD color space conversion
• Re-insert all audio into SD-SDI output
• Re-insert EDH into SD-SDI output
• De-embedding audio and providing 2 pairs of AES/EBU outputs (balanced or unbalanced can be set), and four channels of balanced analog audio outputs
