ONLINE VIDEO IS BOOMING, CALLING FOR SCALABILITY

Online video consumption
growth in 2018-2019
period
25%
of Internet Traffic will be
video by 2022. And 15% of
it will be live.
82%
3. 60% 2 sec
Almost 60% of people
would be more likely to
watch live sports online if
the stream was not
delayed from broadcast.
A majority of viewers will
abandon video services
after less than two
seconds of zapping time.
Lean back experience
becomes the minimal
requirement
ONLINE VIEWERS ARE MORE DEMANDING THAN EVER
4. Near real time interactivity

13. HESP: BRINGING HAS TO THE BIG SCREEN THE RIGHT
WAY
HAS protocols have already established a decent
footprint on most mobile devices and streaming devices
For IPTV and delivery to STB however, HAS has
significant downsides
HESP aims to solve this problem by optimizing delivery
towards these platforms as well, targeting RDK and
Android TV based STBs

14. HESP FUNDAMENTALS = SIMPLICITY
REDUCING OVERHEAD AND INCREASING PERFORMANCE
Manifest is not needed to start playing the stream.
Low frequency updates
HTTP/1.1 based (HTTP/1.1 CTE & Range Requests)
HTTP/2 frame based streaming
Initialization stream: can request images at any moment to start playback
Continuation stream: can continue playback after any initialization stream image
MINIMALISTIC MANIFEST
HTTP DELIVERY
TWO COMPLEMENTARY
STREAMS
21. MAXIMAL GAIN
Target: lowest latency, lowest bandwidth, lowest zapping
times, …
Continuation stream
Long CMAF-CTE segments (minutes)
Ultra-short chunks (1 frame)
P (and I) frames only (referencing only one previous
frame)
MAXIMAL COMPATIBILITY
Target: re-use LL-DASH and LL-HLS streams
Continuation stream
Regular sized CMAF-CTE segments (~6 seconds)
Small chunk sizes: ~200msec
B frames possible: B B B P subgops (in a chunk)
No bandwidth gain
HESP latency, zapping times, startup time gain

23. VIDEO CONTROL FLOW
Video = complete
feed to viewers
Video is a set of
presentations
The presentation is
the lowest granularity inside a manifest.
24. Presentation is a set of
segments.
Segment addressing
happens automatically within a
presentation for an efficient and continuous delivery of the continuation stream
