Whitepaper: HEVC Real-time Software Encoder for 8K Live Video Applications

By Sergio Sanz-Rodríguez, PhD — The whitepaper presents Spin Enc Live, a state-of-the-art HEVC real-time software encoder optimized for 8K live applications in broadcast and Internet streaming.

Spin Digital has released its new product called Spin Enc Live, a high-quality and high-performance 8K HEVC real-time encoder designed for high-end applications, such as 4K/8K broadcasting and live streaming, using a software CPU-based solution.

The new encoder produces quality and compression levels similar to best-in-class offline encoders (typically used for VoD) while, at the same time, providing the performance required for processing 8Kp60 videos in real-time.

The encoder fulfills the requirements of 8Kp60 broadcast and streaming applications, with a stable real-time operation at up to 120 Mbps and a minimum end-to-end latency of 2.96 and 0.75 seconds in its high-efficiency and low-latency modes, respectively. The encoder provides the I/O modules needed for complete applications such as 12G SDI video (and audio) capture, and TS over IP (TSoIP) and chunk-based live streaming (HLS).

Spin Enc Live can also be used for other applications than UHD-TV including immersive live and 360° video. Real-time operation can be achieved for other video formats with an equivalent pixel rate as 8Kp60, for example, 360° video in 12Kp30 format. As more computing resources become available with new generations of CPUs higher resolutions and frame rates will become possible.
