Audio Processor Description
Cascading (Multi-Device) BBG-1070-QS Operation and Setup Overview
1-8
Audio Select/Embed
The audio processor operates as an internal audio router for selecting
PiP-input embedded channels 1-16 as channels (as a four-group package) to
be embedded into the combined PiP SDI and HDMI video outputs. The audio
processor function operates with the timing alignment function to align audio
with the selected reference.
Note:
• Output audio always corresponds to a single particular selectable PiP input.
Various output embedded channels cannot be sourced from a mix of various
PiP input embedded channels.
• To maintain conformance with CEA-861D HDMI audio channel line-up
specifications and industry standard SDI convention, the HDMI output
swaps between the C and LFE channels for the HDMI output.
Per-PiP Audio PPM Meters
Each PiP image area has setup controls to provide audio meters in several
formats (channel count) as desired. Each PiP image has an audio meter
display that can display from 2-bar stereo up to all four embedded audio
groups for the audio associated with the PiP input. User controls allow setting
meter complement, position, size, and other graphic attributes.
(See Figure 1-3.) The BBG-1070-QS
multiple BBG-1070-QS devices to operate in a cascading arrangement,
where four of the device inputs serve as program video inputs, and the fifth
input receives the cascading combined layout of a preceding BBG-1070-QS
device in a daisy-chain arrangement. In this mode, the
configured to serve as a full-size underlay with
overlays. In this manner, added PiPs can be positioned within the imported
underlay resulting in a combined image of the imported underlay PiPs and the
locally added PiPs.
Cascading Low-Latency Operation
Low-latency modes provide for reducing I/O latency by bypassing the
cascade input framesync. Low-latency modes apply framesyncing when
needed (applying framesync and bypassing low-latency during these
intervals). When alignment is again detected by the local device,
framesyncing is correspondingly disabled and low-latency operation is again
applied.
