In the ever-evolving world of online video streaming, choosing the right protocol is crucial for delivering high-quality content to viewers. Join us as we delve into the world of video streaming protocols – HESP, HLS, and MPEG-DASH – in this informative Slideshare presentation. Our expert analysis will break down the key features, advantages, and disadvantages of each protocol, helping you make an informed decision for your streaming platform. We'll explore their compatibility, adaptive streaming capabilities, and how they handle various network conditions to ensure a seamless viewer experience.

What is
HESP?
● HESP stands for High-Efficiency Streaming Protocol.
● The HESP streaming protocol is an HTTP-based adaptive
bitrate streaming protocol.
● This streaming protocol is specially designed for HEVC video.
● It uses a number of features to improve the performance of
the HEVC Streaming Progressive.
● It can stream videos at ultra-low latency with a maximum
latency of 2 seconds and minimum latency of 0.4 seconds
while showing good bitrate flexibility.

How HESP
Works?
● HESP uses two video streams, the “Initialization Stream”, and
the “Continuation Stream”.
● Both the streams enter the HESP Package.
● The HESP Package transports the streams into the web-
server.
● Finally, the video is delivered for playback.

Pros of HESP
Can stream videos in
ultra-low latency.
Supports adaptive
bitrate streaming.
Supports DRM and
works well with CDN.

Cons of HESP
Not supported by
many devices.
It is technically a bit more
complicated than HLS.

What is
HLS?
● HLS stands for HTTP Live Streaming.
● It is currently the most popular and most
widely used live-streaming protocol across
the globe.
● HLS was actually developed by Apple in
2009 to solve one major problem.
● Apple wanted to create an HTTP-based
streaming protocol that would be
immensely scalable.

How HLS
Works?
● An HLS stream originates from the source where the live
content is being created.
● This source video stream (primary playlist) is then converted
into multiple encoded video files with different bitrates.
● These encoded files (media playlists) are finally segmented
into smaller chunks, for adaptive bitrate streaming.

What is
LL-HLS?
● To solve the latency problem of HLS, Apple
finally came up with an extended version of
HLS.
● It is called the Low-Latency HTTP Live
Streaming Protocol, or LL-HLS.
● This LL-HLS protocol functions almost
similarly to the HLS protocol, with some
small modifications.

MUVI
How LL-HLS
Works?
● A segment is further divided into partial segments.
● A “preload hint” tag is added to the media playlist.
● The block playlist reloads feature ensures that the player
receives a response from the server only when a new segment
or partial segment is available.

Pros of HLS
Excellent device support,
supported by almost all devices.
It is a very technically simple
protocol
It is very easy to implement.

Cons of HLS
The video quality might suffer at
lower bitrates.
The live streaming latency is
comparatively higher.

13. 13
MUVI
What is
MPEG-DASH?
● MPEG DASH is referred to as
Dynamic Adaptive Streaming over
HTTP
● It is by far the most flexible HTTP-
based adaptive streaming protocol.
● It offers immense control and
flexibility over the video quality and
bitrate.

Which Is
Better?
HESP
If you are looking for a protocol that can stream your live videos in real-
time, and offers ultra-low latency (as in the case of news or sports
broadcast), then you might be tempted to incline towards HESP.
However, you will still have to remember that HESP will be supported on
a very small number of devices.
HLS
If you are looking for a protocol that is easy to implement, but can still
offer adaptive bitrate streaming and is supported by almost any device,
then you must use HLS. HLS ticks almost all the boxes perfectly, with
only one drawback – latency.
MPEG-DASH
If you use MPEG DASH, which also offers all the good properties of
HESP like excellent adaptive bitrate flexibility and ultra-low latency
streaming, you will also get the benefit of wider device support!
