  • 10/08/13 2011-10-19 HTML5 and MPEG DASH for Broadcasters © Ericsson AB 2012 Ericsson continuously monitors consumer trends (see E/// ConsumerLab at http://internal.ericsson.com/page/hub_inside/sales/consumerlab/index.jsp) to determine the shape of tomorrow’s market. Research representing opinions of more than 430M consumers More than 80 000 Interviews every year More than 40 countries worldwide This slide shows some findings included in the latest report (Oct’11) In 2011 study the 85% that watch broadcast TV several times per week or more, will grow to 89% if we instead measure weekly usage or more. I.e. 4% watch broadcast TV weekly. Video on-demand (streaming and downloading) goes up in all 7 studied markets except China and Germany: UK 62% (63%), US: 42% (39%), Spain 58% (51%) , Taiwan 62% (52%) Sweden 43% (28%) and Germany 26% (26%) and China 82% (88%) “ 35% leisure time is spent watching TV”, “71% of people time-shift weekly” - Source: Consumer Labs MSMC 2010 (Multiscreen Media Consumption) The increase in smartphones and the popularity of youtube has also affected the use of video in the mobile phone. Usage of watching video clips in the mobile phone has gone up from 12% to 16% between 2009 and 2010 (monthly usage). – ConsumerLabs infocom_media_content_entertainment_JUNE2011 Key take-aways: Importance of TV Importance of linear content Importance of take that content with us (time/place-shift it) In general consumers are watching more video on more devices. What is changing is the usage patterns + the role of certain devices (see Consumer Lab report for the role of devices) Video on-demand (streamed or downloaded content) = Streamed TV shows, downloaded video content and streamed Movies (here we include TV/video ondemand content both from OTT providers and traditional TV providers). In 2010 Multiscreen Media Consumption study, we showed that 93% watch Scheduled broadcast once per week or more. If we instead look at how many watch scheduled broadcast TV several times per week or more, we get a slightly lower number – 88%. I.e. we loose the 5% that only watch TV once per week. In 2011 study the 85% that watch broadcast TV several times per week or more, will grow to 89% if we instead measure weekly usage or more. I.e. 4% watch broadcast TV weekly. Compared to 2010, Broadcast TV goes down in all 7 studied markets except Sweden: UK 87% (91%), US: 83% (88%), Spain 83% (89%), Taiwan 84% (86%) Sweden 83% (82%), Germany 87% (91%) and China 88% (92%) Recording of TV broadcasts also decrease in all 7 studied markets except Sweden: UK 62% (63%), US: 55% (58%), Spain 47% (60%) , Taiwan 42% (52%) Sweden 36% (28%) and Germany 33% (37%) and China 58% (71%) Consumers seem to turn to online on-demand streaming services or in some cases actually preferring watching live content, to watching it afterwards – just because they don’t want social media to spoil their viewing experience. In today’s day and age – it is simply too difficult to avoid getting spoilers! Video on-demand (streaming and downloading) goes up in all 7 studied markets except China and Germany: UK 62% (63%), US: 42% (39%), Spain 58% (51%) , Taiwan 62% (52%) Sweden 43% (28%) and Germany 26% (26%) and China 82% (88%)
  • 10/08/13 2011-10-19 HTML5 and MPEG DASH for Broadcasters © Ericsson AB 2012 We see a clear trend that consumers are moving from a what is on right now, to a what do I feel like watching right now? But now we also see a new trend – consumers are beginning to say: Who else is watching this right now? The social aspects of TV is thus becoming even more relevant and important! Another aspect of this is that consumers not only care about who else is watching something right now, but also what your friends and family is watching in general – what new shows/movies/series might be good for me to start watching (so that I can start taking part of the social community around that content)…the virtual sofa!

  • 10/08/13 2011-10-19 HTML5 and MPEG DASH for Broadcasters © Ericsson AB 2012 I would like to share with you some proof points showing that multiscreen is indeed becoming a key source of success in terms of subscriber and revenue growth for service providers. Conclusions from recent studies have shown that common features amongst the most successful TV service providers were: Innovative and modernized offerings An attractive channel line-up containing categories of entertainment for all audiences Bundling home and out-of-home access across several devices. AT&T’s U-verse IPTV service showed the fastest growth with a compound annual growth rate (CAGR) of 134% between 2007 and 2010. Support for multiple devices: Operators who showed market leadership supported TV viewing on the most number of mobile devices when benchmarked with their competition. PCCW in Hong Kong even extends Multiscreen video to fixed line home phones, while European operators such as Telia and France Telecom are not behind in the game as they have rapidly began launching services to even more mobile devices. I recently read through Twitter that Comcast has just announced a mobile TV app for BlackBerry smartphones. Indeed, no devices are being left behind.

  • 10/08/13 2011-10-19 HTML5 and MPEG DASH for Broadcasters © Ericsson AB 2012 … a word about HTTP streaming technologies… because, although H.264 is the dominant video codec (apart from WebM), streaming can happen in many different ways and operators will have to think about which devices they want to target early on and choose one or more streaming technologies (and DRMs) accordingly. Even when talking about adaptive streaming we are not talking about a single methodology (or even a single coded, e.g. Google and VP8). Listed on this slide are the principal adaptive streaming technologies being deployed today. With regards to live content, their requirements are spread between transcoding devices providing the necessary profiles in the right format and a segmenter constructing the chunks, protecting them, building a manifest file and making them available to origin servers.
  • 10/08/13 2011-10-19 HTML5 and MPEG DASH for Broadcasters © Ericsson AB 2012 Increased cost for service delivery (content formatting for all devices/protocols/drms – especially live, no caching) Customers expect better device convergence as explained above. Consequences are churn and decreased service revenue

  • 10/08/13 2011-10-19 HTML5 and MPEG DASH for Broadcasters © Ericsson AB 2012 Assumptions: 24 HD in 24x broadcast out (1080i out VBR statmux) 24x multi-screen out (1x 720p60, 2x 720p30, 8x SD)
  • 10/08/13 2011-10-19 HTML5 and MPEG DASH for Broadcasters © Ericsson AB 2012 Finally, let’s look at where/how a multiscreen deployment fits into a delivery ecosystem (IPTV focused example, but applies to other use cases also) A turnaround headend will typically consist of many different “boxes”, each serving different functions. With the introduction of multiscreen, an operator will need to purchase a multiscreen function “box”, and at the same time maintain dense non-ABR transcoder. Separate box solution means: Flexibility to expand the different infrastructures when and where needed Co-location is not necessary (broadcast + IT often geographically separate) Optimisation of each architecture to maximum density (e.g. don’t lose profiles in ABR transcoder because the broadcaster transcoder needs BNCs, look-ahead resources, Mux resource, stat mux engine, etc..) Others…? Diagram of a broadcast (turnaround) headend Highlight complexity (system integration capabilities to enable scalability) Multiscreen will be integral part of it (not seen in isolation if target is ‘TV everywhere’ experience)

  • 10/08/13 2011-10-19 HTML5 and MPEG DASH for Broadcasters © Ericsson AB 2012 The market and consumer knowledge within Ericsson is such that the following pillars of belief are driving the development of our solutions (its not all about technology, but consumer needs and sustainable business models for the operators) Core beliefs… Importance of linear: 93% of people still watch linear content every week ( ConsumerLab data) The importance of high quality pictures and sound to the user. Willingness to pay for better experience. Scale problem: Convergence (TV anywhere and the decoupling from the client device) means a scale problem. H.264 as the main codec today and in the short/medium term future (where scale problem will appear first at least) Multiscreen as new TV consumption  a true TV experience  needs to be built into operators business model  integral part of broadcast operations Multiscreen will become a main revenue system for operators and therefore we need to make a sustainable ecosystem out of it. Multiscreen will become a core part of operator’s revenue generation, therefore it is becoming critical that multiscreen solutions become integrated in the main systems. Note: this is not the same as saying that broadcast + adaptive bitrate equipment should be the same but that the both systems should have the same level of integration with ad-insertion, tstv, vod solutions as well as the same reliability, etc.
