Connecting The Program Associated Data (Pad) Port; In-Band Ancillary Data; Out-Of-Band Ancillary Data - Pico Digital XDS-PRO SERIES User Manual

XDS-PRO Satellite Receivers
 Non-associated cues will fire if they are mapped to a relay regardless of what program is playing.
 All cues will be outputted through an RS-232 Tx pin on the receiver's relay port to be used by
downstream systems.

Connecting the Program Associated Data (PAD) Port

The XDS-PRO receivers are capable of receiving and displaying PAD in two different ways. Your Network
will provide baud rate settings for the PAD. PAD settings for the receiver can be configured through the
front panel (Section 3.3.4), or the M&C (Section 6.2). PAD data is output through the port labeled PAD
on the back of the receiver. Please see Section 8.1.8 for information on the PAD port pin-out.

2.8.1 In-Band Ancillary Data

In-band ancillary data is raw asynchronous data embedded within the streaming audio on the same
program PID as the audio. It is fed into the RS232 port of the encoder port and thereby associated with
a single audio stream. MP2 natively supports ancillary data. AAC will be carrying ancillary data in a
proprietary enhancement to the framing protocol (this enhancement will be compatible with all AAC
decoders).

2.8.2 Out-of-Band Ancillary Data

Out-of-band ancillary data is raw asynchronous data associated with a single audio stream but carried
outside of the MP2 or AAC data frame. It is fed into the RS232 port of the encoder port and thereby
associated with a single audio stream. This data may be embedded within the MPEG2 transport framing
structure (TSP) of a single audio stream.
