IQDMX31
3G/HD/SD-SDI De-embedder for Four AES/EBU Audio Streams
The IQDMX31 provides 8-channel digital audio de-embedding for 3 Gb/s SDI, HD-SDI 1.5 Gb/s or SD-SDI 270 Mb/s signals. Audio processing features include gain, invert, delay and channel-level routing, while a video proc amp is also included in the feature set. Its video delay feature allows this module to be used where a Dolby E decoder, for example, is to be placed downstream of the AES outputs.

FEATURES
- 8-channel 3G/HD/SD-SDI de-embedder with 4 balanced or unbalanced AES outputs
- Handles up to 16 channels of embedded audio present on the incoming SDI stream
- Standards supported:
- 3G-SDI to SMPTE ST 424/425 level A & B compatible

- Audio proc amp features including independent gain, invert, mute controls and adjustable delay for selected audio channels
- Any group of embedded audio may be passed unchanged, processed or blanked
- Embedded Dolby E support — pair routing, delay and Dolby E header alignment
- Handles Dolby E and PCM audio present in the same group with detection and reporting
- Able to pass all ancillary data without corruption inc. VANC metadata
- Independent HANC and VANC blanking control
- Input loss detection — default output of black/pattern/freeze
- Up to 9 frames of video delay and 2 seconds of audio delay
- Video controls including video gain and offset
- Built-in test pattern generator and audio tone generator
- 2 SDI inputs and 2 active HD/SD-SDI outputs
