What is a replier in television. Systems of automated insertion of regional advertising. Solutions that work

Regional programs (news, thematic programs) are available in digital quality on TV channels of the first multiplex "Channel One", "Russia 1", "Match TV", NTV, "Fifth Channel", "Russia K", "Russia 24" and "TV Center ", as well as on the radio station" Radio Russia "99.72% of residents of St. Petersburg and the Leningrad region.

The insertion of regional content into the digital signal is made using the distributed program modification technology (TRM). General principle The TRM is that the federal multiplex signal is divided into independent traffic flows. In one stream, television channels that do not require regional modifications are transmitted. In other - television and radio channels subject to modifications. In the regional branch of RTRS, a local box is produced into the necessary television and radio channels, and only they go to the satellite for the second time for delivery to the regions repeaters. Repeaters equipped with a special device - replays, re-sewn multiplex, including television channels with regional content.

To meet the needs of broadcasters in local advertising, RTPs has developed a technical solution of seamless adjustment of advertising in a multiplex flow. The insertion of advertising is made in St. Petersburg with a special device - splice in agreed with a broadcaster time.

Providing the country's population with regional digital broad-speaking broadcasting - one of the tasks of the Federal Target Program (FDP) "Development of TV and Radio Broadcasting in Russian Federation For 2009-2018. "

1. Introduction

The network of digital terrestrial television and radio broadcasting of the Russian Federation in the DVB-T2 standard is designed to cover the population of the Russian Federation by digital hanging of the television package about the programs of the first multiplex in accordance with the Federal Target Program.

The list and order of the television and radio programs that are part of the first multiplex determined by the decree of the President of the Russian Federation, with the mandatory publicly available TV programs that are part of the first multiplex, in each of the regions are subject to modifications in accordance with the requirements of broadcasting organizations.

The question of selecting a digital broadcasting distribution network architecture is of particular importance, since the selection of the variant of this architecture directly depends on the SFN single-frequency networks (SING FREQUENCY NETWORK) of digital broadcasting in each of the regions, quality and cost of communication services provided by FSU11 "Russian television and broadcasting network "(RTRS) broadcasters.

One of the important criteria for the quality of communication services is the likelihood of technical marriage and technical stops, i.e. The likelihood of violations of the normal operation of a digital television broadcasting network. Prerequisite high Quality The services of digital radio television hanging is to provide a certain stock of SFN network stability by the number of bit errors when receiving the programs of the first multiplex in the service area.

In contrast to the DVB-T, the DVB-T2 broadcast standard has more flexibility of SFN single-frequency networks and has a number of features that make it possible to more effectively carry out regional modification of television and radio programs, especially when using satellite signal delivery to transmitting stations.

The purpose of this work is to analyze the methods of organizing the broadcasting of the first multiplex in the DVB-T2 standard of the regional content in various embodiments of the network of digital terrestrial broadcasting of the Russian Federation.

The network of digital terrestrial hanging of the Russian Federation consists of 82 regional networks, in the center of each of which is a regional center for the formation of multiplexes (RCFM).

The federal version of the first multiplex and its temporary duplicas to ensure broadcasting in 5 broadcast zones of the Russian Federation L, B, B, G, and M should be delivered to all RCFM on satellite communication lines. The transmission of the first multiplex signal over satellite communication lines is made in encrypted form.

For comparison of various options for building a network, it is accepted that in each region, with the exception of Moscow, the Moscow region, the SPKG-Petersburg and the Leningrad region, three television and radio channels will be modified: "Russia 1", "Radio Russia" and "Russia 24",

2. Network Software Software Composition

digital broadcasting broadcasting of the Russian

DVB-T2 Standard Federation

The system of software substitution of a DVB-T2 digital broadcast broadcasting network of the DVB-T2 standard has a structure.

consisting of a federal complex of software substitution (FCPZ) and a regional software complex (RCPZ).

The FCPZ (Fig. 1) includes not only the equipment of the federal center for the formation of multiplexes (FTCFM), but also part of the equipment of federal broadcasters, in particular, the equipment of the hardware and studio complex (ASC), which is carried out by generating control of dentities for the substitution system.
