A broadcaster’s cable-cutting customer watches their
favorite sports team live online, but learns what happens
from social media before they see it in the actual “live”
video stream. Talk about spoilers!
While this situation is common, broadcasting live
video to consumers uses satellites, the public
internet, streaming formats such as DASH and HLS,
Video system designers need to overcome these challenges
in many different real-world scenarios. For instance:
For broadcast contribution, broadcasters want
backhaul solutions that can use public internet
connections to transport live remote video and
on-the-ground coverage into studio environments so that it
can be seamlessly integrated into any production including
live interviews, commentary and online content.
Executives with global organizations want to
deliver smooth, seamless interactive “live” internal
all-hands and town hall presentations with Q&A
With gaming, off track betting, and other private
broadcasts, video streaming latency is critical to
assure interactivity and real-time delivery.
For each of these scenarios, the end-to-end latency
threshold must remain very low to ensure that interactions
are fluid and video content is delivered in a timely manner.
Remote conversations require less than 150 milliseconds
of end-to-end latency. Real-time broadcasts such as off
track betting typically demand less than 4-6 seconds.
Neither benchmark can be satisfied with today’s segmented
streaming workflows applied for general purpose internet
streaming. Therefore, video system designers must consider
all the factors that contribute to the total delays from when
an event actually happens and is captured on camera, to
when a viewer can see it on their screen (glass-to-glass).
Delivering Low Latency Video Across the Internet
Video latency can have a huge impact on how viewers experience live video.
