Ericsson: 4 Video Channels O/LTE Use 10% Capacity; Deployed by Telstra

Ericsson announced that "Ericsson and Telstra continue to lead mobile operators in the adoption of LTE Broadcast .. Following a series of successful trials in 2014, Telstra will deploy Ericsson's LTE Broadcast end-to-end solution on their Australian 4GX network.

The LTE Broadcast trials 
(here and here) run by Telstra and Ericsson in Australia have shown that three or four channels of video can be efficiently streamed along with complementary data channels. This traffic used as little as 10% of the 20 MHz carrier to cover all users. 

The adoption of High-Efficiency Video Coding (HEVC) compression further improves network efficiency and potential picture quality (see "ITU New Approved Video Codec will Save 50% Bitrate" - here).

In late February 2015, Ericsson and Telstra demonstrated LTE Broadcast transmission using HEVC encoders. HEVC encoding reduces the bandwidth required to deliver high quality video by around 30-40%, compared with existing MPEG-4 AVC coding, enabling operators to either deliver higher quality video or more channels in the same spectrum.

LTE Broadcast has a number of potential key use cases including new customer content experiences at sporting events, such as tennis, cricket, horse racing, car racing and other special events. Using the technology, event goers will be able to access multiple high quality video streams and event related data. 

Without LTE Broadcast technology, delivery of the video and data streams would have been via unicast, consuming significantly more spectrum and network resources. Delivery via LTE Broadcast will deliver an enhanced quality of experience to a higher number of subscribers than when served via unicast delivery"
