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 Net

dislocates 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
-
branded

experience 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 & DLNA

into their broadcast standard


All TV is encrypted in Japan for

enforcement of NHK TV tax


TV has conditional access card


Stores on NAS


Client gets encryption key from

TV on network, content from NAS

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

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

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 the

Smart 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
