Summary:In the last few years, video consumption habits have considerably evolved in terms of devices and networks. These new tendencies induce new constraints for video coding and broadcasting solutions architecture. The ATSC 3.0 standards scope covers all the components of the distribution chain and proposes recommendations for audio and video coding, content distribution ... In previous works, we designed a SHVC encoder able to perform real-time encodings with interesting bit-rate savings. The Scalable extension of the High Efficiency Video Coding (SHVC) standard enables to encode several resolutions, qualities (SNR), bitdepths, codecs or color-gamut in a single bitstream with bit-rate savings over simulcast. In this paper, we first present the improvements and trade-off on our encoder performance in terms of coding speed and coding efficiency and its integration in a software compression solution. Then, we describe an end-to-end ATSC 3.0 broad-cast/broadband real-time distribution chain we have deployed and tested in lab conditions.
