Overview
Digital television system has the possibility to insert additional data with regular TV-programs. This data may used by the receiver Set-Top Box (STB) for example to show information about the TV- or radio programs through the Electronic Program Guide (EPG). EPG data is transmitted in to the terminals using standardized DVB-SI EIT Tables.
Sofia Backstage® EPG Manager is a scalable solution designed to help professional broadcasting companies as well as any digital television operators to create and manage the EPG content for multiple sources and TV-channels.
Sofia Backstage® EPG Manager can be used to manage EPG information on all DVB compliant digital networks. Service information, specifically Event Information Tables (EIT), is used to populate EPG which provides information about different services provided on DVB Networks.
The EPG Manager can generate new EIT and TDT/TOT tables from XML files or it can extract and manipulate existing SI information from incoming DVB data feed. It can be used by the network operator to multiplex EIT information from several sources (XML, satellite, terrestrial, or cable transport streams) to one large SI EIT system for any type of DVB network.
Sofia Backstage® EPG Manager comes with WWW-based user interface or it can be optionally managed using the XMLbased configuration files.
