Variable channel pair selection for SDI audio

With IHSE’s comprehensive conversion system, embedded audio signals can be de-embedded and output in a variety of formats. For the first time, the IHSE Draco vario extender series allows free channel pair selection of SDI audio.

Commonly used AV and broadcast signals, including SDI, HDMI and DisplayPort include both audio and video signals on a single cable interface. The standard stereo PCM audio signal requires two audio channels. Usually, channels 1 and 2 of eight possible channels are used for audio transmission.

The source audio signal can be on different audio channels. IHSE’s conversion process allows free audio channel pair selection for SDI audio. This allows users to access audio tracks on channels other than the first two channels, ensuring that the video signal is accompanied by sound.

The Draco vario extender series from IHSE also enables comprehensive audio conversion between analog, digital and embedded audio signals. Additional modules allow the output of embedded audio signals via external analog or digital loudspeakers at the receiving workstation. Balanced audio, which is widely used in professional recording studios, is also supported.

The extenders are compatible with the new IHSE IP CPU extender module, receiving audio from virtual machines and outputting in analog and digital form.

“The comprehensive variety of conversion options delivers enormous flexibility and cost savings,” explains Mark Hempel, Product Manager at IHSE. “On the source side, a dedicated audio module is unnecessary, which saves on rack space and cabling. On the receiver side, the system allows the use of low-cost analogue speakers.”
