Virtual STB also corresponds to different concepts
Virtual Set-Top Box
[vur-choo-uhl] [set] [top] [boks]
noun
1. A basic Set-Top-Box where most of the
service execution environment
- e.g. the web browser – is running in a
cloud infrastructure
2. A device which is not a Set-Top Box,
but which acts as a Set-Top Box plugged

Gradual Introduction of Cloud based TV Functions to Legacy Networks

IPTV launched in France 10 years ago – 6.5 million digital TV (IPTV / satellite ) customers in Europe Live TV & VOD services available in OTT on SmartTV and Xbox game consoles

- 9. 9 What can we learn from our Cloud based gaming service offer?
- 10. 10 Orange launched its cloud gaming offer for TV in October 2011 Rely on the G-cluster product Around 200 games Games can be tested for free during 20 minutes Different Business models – Transactional: 24H, 48H, 1 week – Subscribed: – Basic: 50+ games, 5€/month – Premium: 150+ games, 15€/month – Electronic sell-through
- 11. 11 A Cloud gaming solution can make sense for STB Native games induces high-end STB – Aggressive GPU, CPU – An additional costs for every STB, while that extra feature may not be used by everybody At least for low-end STB, cloud gaming is a good trade-off – But the main issue is latency The latency is the amount of time between the stroke of a button on the gamepad (or the move of the stick) and the update of the UI – Perception threshold: 120-150 ms – Annoying for the user (in gaming context): >350 ms
- 12. 12 Residential Gateway Game Servers STB IR: 130 ms Wired: 30 ms RF: 45-55 ms BT: 55-65 ms Ethernet: negligible Wi-Fi: 50 ms Ethernet: negligible Wi-Fi: 50 ms Fiber: 2-3 ms ADSL: 20-30 ms Fiber: 2-3 ms ADSL: 20-30 ms 50-70 ms HDMI: negligible 20-80 ms Best case: 125 ms versus Worst case: 500 ms 20-60 ms TV Remote Control: • Not relevant for all games Game Pad: • Latency between sticks and buttons may be different • We selected RF Home Network: • So far, our STB in the field are not in Wi-Fi Game Servers: • Video encoding tuning is key (a good frame rate is mandatory) STB: • A low latency buffering policy is mandatory TV: • Monitors are often better than TV in term of latency • “Gaming mode” must be turned on
- 14. 14 Orange services have been launched on connected CE devices for several years Infotainment services are available on – LG (March 2010 in France, August 2011 in Poland) – Samsung (November 2011) Our live TV channels are available on – XBOX 360 (April 2012) – Samsung Smart TV (February 2013) – LG Smart TV (July 2013) – XBox One (November 2013) Our VOD service is available on – XBOX 360 (April 2013), – Samsung Smart TV (July 2013) The strategy is to target second screens at this stage – The STB is still the preferred device in the living room Smart TV Orange portal in 2010 Orange VOD on XBOX 360
- 15. 15 Our experience is positive in many ways Innovative devices Good relationship with the partners Constructive exchanges Co-marketing opportunities But we have also identified several topics that we must improve together WebTV linear channels on SmartTV WebTV linear channels on XBOX 360
- 16. 16 Our biggest fear is regression We have faced regression with all our partners Examples (not the complete list): – Regression with persistent PlayReady license – Regression due to heuristic changes in Smooth Streaming player – Regression in rendering Live streams in Smooth Streaming – Regression in dealing with the same origin policy for XHR requests – Etc… Regressions are unfortunately unavoidable, but: – It is more complex to identify regressions for a CE manufacturer with 100+ partners, due to the distance from Korea or US, than for a telco with its end-to-end controlled solution in its premises – So, regressions are identified too late (after a firmware upgrade in some cases), and the probability of facing regressions is higher on CE devices than on a STB
- 17. 17 And when a regression occurs, the following questions come up straight away 1 2 3 Are we the only partner impacted ? Is the firmware already rolled-out ? Was it the latest firmware for that device ? Yes Yes Yes + + Very bad news
- 18. 18 Firmware management is the second hot topic As we do not control the device, we have no control on – the features included in the firmware – when the firmware will be rolled out – which kind of firmware will be rolled out (mandatory or optional update) Firmwares do not always behave the same way (differences between mid- range and high-end models within the same line-up) We lack visibility on the scope of the firmware – In almost all cases, there is no release note available for partners
- 19. 19 And last, but not least, the support is more complex Today, we have representative configurations of households in our premises (STB + gateway) – This is a really useful means of reproducing customers issues When we rely on Smart TV, this is not possible – Between 2 and 4 different platforms by manufacturer each year – In some cases, there are several different firmware releases in the field for a same device It is very hard for hotlines and technicians to help our customers
- 20. 20 What the Cloud Computing could bring to the TV ecosystem?
- 21. 21 Cloud computing is a revolution, like when we switched from water wall to water tap Source: http://www.whitehouse.gov/blog/2010/05/13/moving-cloud
- 22. 22 Cloud computing brings lot of opportunities… Elasticity – Can adapt to workload changes by provisioning and deprovisioning resources in an autonomic manner A better Time-To-Market – Prototype easily in production environment with very little investment – Very helpful with a DevOps approach – A more flexible solution to address different market size – Cf. Orange footprint in different countries Can (potentially) save money – More OPEX oriented with a pay-as-you-go billing model – But you must monitor the usage of cloud services and track costs – And not forget to release resources…
- 23. 23 But lot of challenges as well… Migrating existing applications to the Cloud induce lot of impacts – Must migrate stateful components to stateless – More data centric than component centric – Applications must be designed for failures And the challenges are not technical only – Impacts of organizational change – Do not underestimate skills shortage – Service Level Agreement – Security
- 24. 24 So, do not underestimate the migration path The safest way for migrating an existing IPTV platforms to the cloud is – To avoid a big bang approach – To analyze your data first (consistency, durability, read/write cycle, security, repository…) – And only then the impacts on your components – To set up tools and to automate as much as you can (Deployments, Configuration, Error recovery, Elasticity, …) And do not forget – “Release early, release often“ – “If at first you don't succeed, try again”
