It is an advanced service that enjoys the Digital Video Network (RVD) of RNP, server infrastructure throughout the national territory for the distribution of audiovisual content. Through it, it is possible to transmit events in real time and high quality.

In this way, the client institutions that want to broadcast live an event held in their organization do not need to have a robust server or a large band capacity, to attend to the innumerable simultaneous accesses of users and viewers. The optimization is carried out through a connection Stream Live Content for Your Audience of that local server with the Digital Video Network (RVD), according to the user access demand.

How does it work
The service transmits events in real time, and is not, therefore, the recording for subsequent disclosure or supply of the necessary infrastructure for capturing and encoding audio and video in the premises, which is the responsibility of the client.

Its operation occurs from a computer of the client connected to the Internet, which encodes the images in the premises of the event. Then, the video is captured and distributed over the network, through the distribution infrastructure called Digital Video Network (RVD). The server equipment that make up the network are called reflectors, because they act as repeaters of the video that is being transmitted, ensuring that viewers access Transmission more quickly and the client (organizer of the event) saves resources.

In 2012, a software infrastructure update project enabled the TV Signal Transmission service to expand the number of local servers and, consequently, the capacity of simultaneous accesses from the RNP backbone or outside it. The same work also brought the incorporation of new security resources, which allow greater control over content traffic.

How to adhere
All the RNP client institutions can join the service quickly, through a technician who will be responsible for the following necessary local infrastructure:

A computer connected to the Internet with a fixed IP address and with software capable of performing this coding;
A video source, directly connected to the computer or a capture device;
An internet connection with enough upload band to support Video streaming;
Release of the door that is being used for Streaming streaming, in the local firewall.

Curiosities about the service

RNP initiated the transmission of events in real time in 2001, on an experimental basis. In the following year, it was used, for the first time, the multicast technology to transmit a course of the Institute of Pure and Applied Mathematics (Impa), in Rio de Janeiro, for several Brazilian states. The live video transmission service was officially offered by the organization as of 2003, based on a network of digital video reflectors that implement multicast in the application layer.

Since then, the service has met the demands of many user institutions for the transmission of seminars, conferences, courses and even space missions. At the request of the Brazilian Space Agency (AEB), RNP transmitted, in 2006, images of the mission of the first Brazilian astronaut, Marcos Pontes.
