Disruptive Tech: Open-Standard Secure Vid. Net

Open-Standard Secure Video Network Open-Standard NNW Networking Open-Standard Public-Private Key Encryption Open-Standard Content Search & Discovery Inexpensive MPEG-4 AVC Decoders

Why Its Disruptive Open-standard clients … could be anything!

Key Complements Open-standard remote user interface (Necessary in some

Mkts.) Broadband Cable Tuners / Full-band Capture Inexpensive transcoding ASSPs iPads

Distance + Generic Clients = Game Changer

Open-standard Secure Video Netdislocates the STB: 5m -> 100m

One server per home

No-new-wire Video Networking

HD MPEG-2 is 16 Mbps, HD MPEG-4 AVC is 8 Mbps Overhead needed for low latency, reliability, fast

forward & other trick modes MoCA currently dominates open-standard

deployments HomePNA only real deployed competitor 802.11ac and G.hn are real possibilities In North America, video over coax to most TVs,

only over Wi-Fi to tablets & notebooks NNW networking standard is operator-specific, CE

will have Wi-Fi & Ethernet. Transceivers common.

Open-standard Encryption

For the home, “fancy” encryption isn’t needed, only link protection

“Fancy” digital rights management is nice to have, BUT The home can be “fenced in” by a max 7ms lag

Role of the DTLA / DTCP-IP Certification & Indemnification

How to secure HLS+ In the apps for iOS / Android i.e. iOS / Android API is the open standard

Its Just Software (i.e. can be updated)

Open-standard Content Discovery & Streaming

Earliest of the parts to emerge DLNA / UPnP A/V – A great starting point HLS + web or app based discovery works too Its “Just” Software

Note DLNA calls DTCP-IP-secured DLNA video:DLNA Premium Video

Inexpensive MPEG-4 AVC Decoders

The price premium of HD MPEG-4 AVC over MPEG-2 is less than $3.

Cost in TVs subsidized by Internet video royalties

Remote User Interface

In North America, remote UI is a key part of this technology

DirecTV has deployed RVU Most other solutions looking to HTML5 W3C has become key standards body for this effort

Without good remote UI, operator-brandedexperience can’t be delivered to clients

Regulation in US

CableCARD In North America, the $40-$50 cost of adding CableCARD to a

STB is a key economic driver of Server/Client architecture Best to keep it to one CableCARD per household

AllVid The FCC has learned of the open-standard secure video

network Mandating its use was discussed in national broadband plan Called “AllVid” AllVid has been in the “Notice of Inquiry” stage for 2 years Industry consensus: No action pending unless democrats

sweep in November – even then maybe not

Complementary Technologies

Broadband Cable Tuners / Full-band Capture A new generation of tuners that aren’t really tuners Able to capture 8, 16, 24 channels from across cable

spectrum Shipping from Broadcom, Announced by MaxLinear

Broadcom has applied to satellite as well Simply tilts the economics more in favor of a server/client

architecture

Transcoding Fit the signal over Wi-Fi Optimize for viewing on different devices “Fair-use” limits to one unmanaged device per server I am not a lawyer

What it looks like - Japan

Japan wrote DTCP-IP & DLNAinto their broadcast standard

All TV is encrypted in Japan forenforcement of NHK TV tax

TV has conditional access card Stores on NAS Client gets encryption key from

TV on network, content from NAS

What it looks like – Everywhere Else

The Android smartphone is set to become the first media hub of the global smart home

Non-iOS smartphones are looking to open-standard content sharing as inexpensive differentiator from Apple

Therefore, most include a DLNA server

Strength in numbers … more later

Definitions

TV Gateway Server – A device that provides an interface between a local-area network and a television broadcast platform.

The gateway will typically: Include all of the tuners and demodulators Translate conditional access into DRM (CA termination)

Thin IP Client STB – A tuner-less STB that also doesn’t support proprietary conditional access

Thin IP Client software can also be loaded on other devices

North American STB Market

From 2012-2014, forecast of mostly test-sized deployments

In 2015, testing phase is over and GW + thin client architecture becomes standard except for AT&T and Canadian Bells.

Smartphones

Outside of North America & Japan, smartphones dominate in-home video content distribution

This only includes non-iOS smartphones w/ DLNA servers

What does this have to do with the rest of theSmart Home?

Not much, actually Key hardware element in home control

applications is bridge: From low-power, low-bandwidth wireless net (ZigBee, Z-

Wave) To high-power, high-bandwidth net Video happens strictly on high-bandwidth net

Smart home interfaces should be remote-UI ready, concentrate on operator-driven support, integration into operator apps on iPad, etc.

TVs themselves might add smart home control interfaces too, but less likely
