What is SAT>IP?
2
is a Communication Protocol for satellite reception devices on IP networks
First presented at SES Industry Days in 2011
Adopted and supported now by over 40 manufacturers worldwide
Since March 2014 available as CENELEC standard EN50585
SAT>IP will make satellite services:
1. available on more devices (tablets, smart phones, …)
2. transportable via IP in-home infrastructures and in professional environments
Advantage 2: Sat-distribution via IP
4
or IP-LNB
All free-to-air and encrypted channels are transported via the IP network
For encrypted channels the STB or TV requires a CA subsystem
Watching encrypted content on an IP device requires implementation of a CA-to-DRM system
Architecture
SAT>IP distinguishes between Servers and Clients
Clients request live satellite TV programs from servers
Servers provide live satellite TV to clients

Media Protocols

SAT>IP Servers:
- answer client requests
- remove the DVB-S/S2 physical layer
- encapsulate in IP (unicast or multicast, RTP or HTTP)
- transparently forward TS Packets to clients
SAT>IP clients
SAT>IP clients:
- remotely request TV programs (DVB TS packets) from a specific satellite transponder
- specify the IP protocol in which they would like the program delivered
- display the program to the user

SAT>IP protocols
Fully aligned with existing in-home networking and internet standards
• Addressing
• Discovery
• Description
• Session Setup / Control: RTSP / HTTP
• Streaming: RTP / HTTP
• Real-Time Session Information: RTCP
SAT>IP is based on open industry standards

SAT>IP is standardized as CENELEC EN50585
Device certification
Interoperability of products is key for a successful market introduction:
- SES currently handles product certifications
- Provision of reference servers to SAT>IP developers
- Availability of software testing tools for developers
Certified devices may carry the SAT>IP logo:

The IP-LNB
RJ45 (GbE)
Home Network
• The IP-LNB incorporates 8 tuners and
demodulators capable of serving up to 8 IP
devices on the in-home network with high quality
satellite programmes
• An SES lead innovation initiative with leading
international industry partners
• Status: shipped to SES customers & partners

IP-LNB building blocks
Significant additional hardware beyond a Quatro LNB
But 8 (!) DVB-S/S2 front-ends incorporated
Software represents majority of development effort/costs 12

SAT>IP Alliance
21
At NAB 2015 the SAT>IP Alliance will be launched
An non-profit organization open for all manufacturers, satellite and TV operators
Scope: further develop and promote the SAT>IP communications protocol
Conclusions
22
SAT>IP brings satellite TV to a plethora of IP devices and supports cost-effective
distribution of satellite TV in hotels via (existing) IP infrastructures
Over 40 manufacturers support SAT>IP with already more than 75 products
− Flat screen TVs from Panasonic and soon TP Vision (Philips)
− IP-LNB and IP flat antenna available
− SAT>IP specification optionally supports DVB-C and DVB-T
The SAT>IP Alliance will be announced during NAB 2015 and combine the
engineering and marketing power of world-leading companies to support SAT>IP
Next step: publication of an “Operator Extension” to support transcoding and CA-
to-DRM solutions
