Demo: UHD live video streaming with a real-time scalable HEVC encoder

摘要

In this paper we present a real-time streaming demonstration with a multi-layer architecture of a pipelined software High Efficiency Video Coding (HEVC) encoders with inter-layer prediction enabling Scalable HEVC (SHVC) encodings. This SHVC encoder is implemented on an innovative platform performing real-time encodings that already demonstrated promising performance with HDR, HFR and SHVC implementation in previous demonstrations [1], [2]. The transmitted content consists of a spatial SHVC bitstream composed of a High Definition (HD) Base Layer (BL) and an Ultra HD (UHD) Enhancement Layer (EL). The encoder reads an UHD video sequences through Serial Digital Interface (SDI) ports and broadcasts the SHVC bitstream through an Internet Protocol (IP) channel. The bitstream is then decoded using a GPAC player with a real-time decoder.
