The European Championships 2018 provided an opportunity for the IRT in collaboration with the EBU to show how audiovisual content produced in the state-of-the-art formats both live and on-demand can be distributed to large audiences in the 5G environment.
As part of the 5G-Xcast project, several trials were conducted during the week of the event using the LTE eMBMS test-bed that IRT is running in collaboration with Nokia and Bayerischer Rundfunk. Learn more about our test-bed here.
A similar setup has been built in the form of a demonstrator for the upcoming IBC show in Amsterdam.
Visit our demo at the IBC 2018 in Amsterdam, 14-18 September 2018 (EBU 10.F20).
Point-to-Multipoint capabilities in 5G
This demonstration shows the value of point-to-multipoint capabilities in 5G, especially for a large-scale distribution of the popular content such as premium sports. The demonstration Highlights the following aspects:
- fixed/mobile convergence
- combined use of unicast and broadcast capabilities
- use of standardized 3GPP interfaces to deliver MPEG-2 Transport Stream including live TV programmes and HbbTV service information
- free-to-air reception
- reception on both mobile/portable user devices and stationary TV-sets
What does the demonstrator consist of?
Live TV Broadcast with Additional On-demand Services over Unicast
Live TV content and the signalling for add-on services based on the HbbTV standard were both included in an MPEG-2 Transport stream and transmitted over the
LTE eMBMS broadcast system. The broadcast signal is received by stationary
eMBMS-enabled TV receivers and by smartphones simultaneously and without the need of unicast connectivity.
Users can access additional on-demand content either via an HbbTV application on TV sets or an HTML-based application on mobile phones. The on-demand content is delivered over the LTE unicast link in the mobile network. This gives an outlook on the coming technology convergence and future capabilities of 5G.
- Content is provided by the EBU from the European Championships venues. Encapsulated in a MPEG-2 Transport Stream alongside live TV programmes, HbbTV signalling is inserted pointing to additional on-demand content offered by the broadcaster.
- A small-scale computer-based solution including LTE EPC, MBMS and radio stack permits the delivery of the broadcast signal (MPEG-2 TS over RTP) in LTE downlink and the allocation of the remaining unicast capacity for on-demandtraffic.
- Internet connectivity provides access to the servers with on-demand content. Broadcasters can direct users to their own content repositories.
- Smartphones with Expway’s middleware allow users to watch live TV programmes via the broadcast system and on-demand content via a mobile web application and a unicast internet connection.
- A smartphone acting as a set-top-box forwards the original MPEG-2 TS to a TV-set that can tune to the live TV signal with the possibility to access HbbTV Services.
