In a NEXUS system, the XSDI board is provided to make available the audio embedded into an SDI digital serial video stream as specified by SMPTE-259M (SDI). In addition, any audio existing on the NEXUS system can be written to the video stream. The board features a video input and a video output. This allows any video to be transparently forwarded with no need for additional hardware components. Of course, it is also possible to use the XSDI as a pure input board for extracting (de-embedding) audio from a video signal. Unlike competing solutions, the XSDI was designed as a generic SDI audio interface. The board was developed from scratch. (Standard applications were not accessible during the development process.) It offers a variety of options for reading the audio from a video stream, or adding it to the video signal.
- Audio embedder/de-embedder for SMPTE-259M video (SD)
- Combined I/O board for all 16 audio channels
- De-embeds, embeds, replaces, and/or deletes audio
- Free channel routing on the NEXUS
- Internal DSP for signal adaptation
- Re-quantization to 16 or 20 bits with noise shaping and dithering
- Test-pattern generator integrated
- Either BNC and/or LC optical ports
- Option: XSRCA01 SRC module (required for asynchronous video input, or if the system or interface rates differ from 48 KHz)
- Officially certified by Dolby® for Dolby E signal transmission
