WHITE PAPER | DELIVERING LOW LATENCY VIDEO ACROSS THE INTERNET
In this white paper, we examine key factors to consider when
delivering video using the public internet. The key factors
are inherent to the different stages of delivering low-latency
video glass-to-glass. The stages are the following: Encoding,
Decoding and Transporting.
We’ll start by examining Encoding and Decoding, then how
the Transporting process can impact video delivery, as it has
its own complexities that should be considered separately.
Latency from encoding the video stream depends
heavily on the selected approach, as latency contribution
can range significantly – from under 1/10 of a second
( 100 milliseconds) to over 10 seconds.
Using broadcast-quality encoders provides very high-quality
techniques such as multi-pass compression, but introduces
a significant amount of latency.
Software-based encoding can provide flexible, high-quality, non-latency-critical streaming with adaptive bitrate
capabilities. Performance will vary and is dependent on the
content, the streaming set-ups and bitrate cascades, as well
as on CPU/GPU configurations.
Enterprise class hardware encoders can provide a cost-effective, flexible, high performance, and highly deterministic
option suitable for many low-latency applications and
encode in high-quality formats such as H.264 and HEVC that
facilitate internet streaming.
Haivision’s award-winning Makito X encoder transports
secure, low latency, HD video over any network at extremely
low bitrates using H.264 and HEVC. The Makito X is ideal
for live, interactive and headend applications, especially in
cases where reliable, 24/7 uptime is needed.
