Introduction

 Up to 47 (x the number of modules) audio and data components can be passed

through per chassis.

Note: The maximum number of pass throughs per module also applies to the

above scenarios.

Each video service can therefore have up to eight transcoded audios and up to eight

passed through components (audio and data).

1.3.2.5 Output Audio Duplication

Both transcoded and pa

ssed through audio outputs can be duplicated to produce up

to four copies of each. These copies are required for sending to different MPTS’s

and/or different IP addresses.

1.3.3 Data PIDs

1.3.3.1 Data Pass Through

The SPR1100 will pass through the following:

 DVB Subtitles.

 Teletext.

 Closed Captions (passed through and recaptioned).

 WSS.

 AFD (which will be corrected to reflect and aspect ratio change.

 EBIF.

 SCTE 127 VBI

 Private data such as interactive TV, PIDs and tables.

Data PIDs are passed through and re-time aligned with the transcoded video they

are associated with.

1.3.3.2 Quantity of Data Pass Through

The possib

le quantity of audio pass through is defined by the sum of audio and data

pass through. See Section 1.3.2.4 for further details.

1.3.3.3 Output Data Duplication

Output data can be duplicated to pro

duce up to four copies of each. These copies

are required for sending to different MPTS’s and/or different IP addresses.
