3.7.16 SCTE-27 Subtitle Processing
The AVP 4000 is capable of processing up to two SCTE-27 components per output
service. The SCTE-27 components are input to the AVP 4000 from IP sources. The
processing offered is to either pass-thru the components onto the output service, or
to translate the components into DVB subtitle components. Set up of SCTE-27
pass-thru is similar to set up of DVB subtitle pass-thru, see
3.7.15.1 How to Set Up
DVB Subtitle Pass-thru on Encode Services
.
3.7.16.1 How to Set up SCTE-27 to DVB Subtitle Translation for Encoding Services
Incoming SCTE-27 components arriving over IP can be added, as DVB subtitle
components, onto an existing encoded service (in which the video and audio input
arrives over SDI). It is assumed that the SDI and IP sources are generated
somewhere upstream by the same device and hence are synchronous. The AVP
4000 will not synchronize the separate components.
1. Set up the encode service according to section
3.7.5
.
2. Set up the IP input according to section
3.7.10
paragraphs
6
and
7
.
3. Select the required SCTE-27 component from the IP input, drag onto the encode
service, and select Transcode in the popup dialog box. Set the other
parameters as required and select Finish .
