Managing OTA SSU transport stream

Introduction

Icareus Playout OTA SSU Server is a playout system for delivery of OTA SSU transport streams and related tables (e.g. PMT, UNT related etc) over DVB services.
When a transport stream file is uploaded to new OTA SSU TS instance, it is parsed and all input PIDs from it are displayed to choose from.
Parser informs if the file is not valid OTA SSU transport stream file.
