TeleTAG

PREPARATION AND MANAGEMENT OF TV PROGRAM METADATA (ELECTRONIC PROGRAM GUIDE)

TeleTAG system is designed to prepare and manage TV program metadata (Electronic Program Guide).

The system consists of hardware and software that support metadata generation: creating or importing from external sources, editing, processing and metadata outputting in accordance with the requirements of each type of operators

The system comprises central server and client’s software. Central server consists of database, module that generates streams of Event Information Table (EIT), in accordance with ETSI EN 300 468 Standard, module that generates SI tables, in accordance with ETSI EN 300 468 Standard, STB software update module (DVB-SSU), in accordance with ETSI TS 102 006 Standard. The system can generate up to 500 Mbit/s data streams simultaneously. The client’s software consists of system administrator tool and metadata editor tool, which performs intelligent editing and control over metadata integrity and validity.

The system supports for an automated import of metadata from external service providers, as well as an automated export of processed metadata in popular formats, which allows using the system both on traditional digital TV platforms (DVB-T, DVB-S, DVB-C) and on DVB-H and IPTV platforms.  

TeleTAG system has the following key features:

  • Imports and exports metadata delivered by external service providers in the XMLTV format;
    • Metadata intelligent editing:
      Control over the size (length) of text fields;
    • Spelling check;
      Data validity check (time gaps, time overlap, event duplication);
    • Control over data integrity;
  • Supports metadata in different languages simultaneously;
  • User interface in English and in Russian;
  • Generates Event Information Table (EIT) data and SI tables, in accordance with ETSI EN 300 468 Standard;
    Generates data stream to update software on STB;
  • Supports interactive applications in accordance HBBTV 1.5 (ETSI TS 102 769) specification;
  • Easy license upgrade for up to 500 Mbit/s of TS streams;
  • Flexible system management to generate outputs in accordance with the technical requirements of the operator;
    Program interface (API) designed for quick integration with the systems of third parties (CAS, Middleware, etc).

Metadata Upload/Upload Module
  • The TeleTAG system allows loading (import) and unloading (export) the metadata stored in the database in XMLTV format (http://wiki.xmltv.org);
  • Import/export of metadata is carried out automatically. Data can be either uploaded/downloaded to a special directory in the TeleTAG system, or uploaded/downloaded to/from a directory on another server in the network.
  • Operation parameters can be configured by the system administrator;
  • During data import/export operations, the following network protocols can be used: FTP, SFTP, SCP, Samba, NFS;
