Using the Equipment
- SD-SDI – Only SD video will be output from this Output BNC connector.
- 3G-SDI – This configures the Output BNC connector for 3G-SDI required for
outputting 1080P video content.
- AS – The Output BNC connector will output the incoming Transport Stream
providing an ASI source for down-stream equipment.
• 3G-SDI Level – Specifies the mapping scheme for transporting the
uncompressed video and its components into a serial digital interface operating
at a nominal rate of 3 Gbps.
- Level A – Is the direct mapping of an uncompressed 1080p video stream
into a serial digital interface operating at a nominal rate of 3 Gbps.
- Level B – Is the dual-link mapping of a 1080p video stream into a serial
digital interface operating at a nominal rate of 3 Gbps.
3.18.2.8 SDI Embedded Audio
Besides the video, up to eight audio groups can be embedded into the SDI output.
Configuration of the Embedded Audio Groups is done so from the Decode > Audio
Output Routing page. Each group can hold four channels so typically two decoded
streams each containing a stereo pair is mapped to a single group.
Figure 3.156 SDI Embedding Window
This is further explained in the Audio section above.
HD-SDI also supports data embedded into its VANC area, this is embedded as per
SMPTE 292M and controlled from the Decode > VBI-VANC sub-menu.
