Why is HD Important - End User Relevance

Its not the technology

Its how end users respond

Are they willing to pay?

Sky has ~10M subscribers,

over 2M are HD subscribers. A number which grew by 0.5 M last year.

They charge £10 pm addition for NO more channels.

My wife ‘is that HD’


12 Million Subs

Instant Watching of 17,000 titles

Time Warner content 28 days after

DVD release

On Demand through Over-The-Top

Increasingly we are not satisfied with a broadcast schedule

Catchup TV: 115 million requests in December ~45% increase YoY

Of these, 94 million were from online users

Of the television requests, only 3% were for download

Live Streaming

Catch-up on programs

Bandwidth Requirements for HD

IPTV systems settled on ~6Mbps for ‘HD’

Using AVC Codec

AT&T Uverse is 6.5Mbps

Pragmatic rate for copper wire delivery (up to 20Mbps)

But BBC HD reduced bit rate from 16Mbps to 9.7Mbps last Aug

Satellite viewers complained reporting picture quality and sound issues (720p)


Wireline – there is capacity at the edge

Network Impact

As bandwidth requirements accelerate, the current unstable industrymodel will come under increasing pressure, requiring significant scaling

of the network and further investment

Leveraging the network to enable content delivery


HTTP Adaptive Streaming (HAS)

Examples:

Move Networks

SmoothHD Streaming

Apple Live Streaming

Automatically adapt to bandwidth available

Media broken into segments (2-10 seconds long)

Encode each segment into different bit rates

Client pulls segment at bit rate it believes is sustainable


Will end users accept variable quality?

What do they want more

Instant start

< 5 seconds to start

No hesitation

Once started, the stream does not jitter

4 out of 5 viewer leave if stream buffers once

Quality image

Starting a research program to see how end users respond to variable quality.
