Full Article: Online Video Usage – YouTube thrashes iPlayer, but for how long?

Online Video consumption is booming. The good news is that clearer demand patterns are beginning to emerge which should help in capacity planning and improving the user experience; the bad news is that an overall economic model which works for all players in the value chain is about as clear as mud.

We previously analysed the leffect of the launch of the BBC iPlayer on the ISP business model, but the truth is that, even in the UK, YouTube traffic still far outweighs the BBC iPlayer in the all important peak hour slot – even though the bitrate is far lower.

Looking at current usage data at a UK ISP we can see that the number of concurrent people using YouTube is roughly seven times that of the iPlayer. However, our analysis suggests that this situation is set to change quite dramatically as traditional broadcasters increase their presence online, with significant impact for all players. Here’s why:

Streaming Traffic Patterns

Our friends at Plusnet, a small UK ISP, have provided Telco 2.0 with their latest data on traffic patterns. The important measurement for ISPs is peak hour load as this determines variable-cost capacity requirements.

iPlayer accounts for around 7% of total bandwidth at peak hour. The peaks are quite variable and follows the hit shows: the availability of Dr Who episodes or the latest in a long string of British losers at Wimbledon increase traffics.

Included within the iPlayer 7% is the Flash-based streaming traffic. The Kontiki-P2P based free-rental-download iPlayer traffic is included within general streaming volumes. This accounts for 5% of total peak-hour traffic and includes such applications as Real Audio, iChat, Google Video, Joost, Squeezebox, Slingbox, Google Earth, Multicast, DAAP, Kontiki (4OD, SkyPlayer, iPlayer downloads), Quicktime, MS Streaming, Shoutcast, Coral Video, H.323 and IGMP.

The BBC are planning to introduce a “bookmarking��? feature to the iPlayer which will allow pre-ordering of content and hopefully time-of-day based delivery options. This is a win-win-win enhancement and we can’t see any serious objections to the implementation: for the consumers it is great because they can view higher-quality video and allow the download when traffic is not counted towards their allowance; for ISPs it is great because it encourages non-peak hour downloads; and for the BBC it is great as it will potentially reduce their CDN costs.

YouTube traffic accounts for 17% of peak-hour usage – this is despite YouTube streaming at around 200kbps compared to the iPlayer 500kbps. There are about seven times the amount of concurrent users using YouTube compared to the iPlayer at peak hour. Concurrent is important here: YouTubers watch short-length clips whereas iPlayers watch longer shows of broadcast length.

P2P is declining in importance

The real interesting part of the PlusNet data is that peak-hour streaming at around 30% far outweighs p2p and usenet traffic at around 10%. Admittedly the peakhour p2p/usenet traffic at Plusnet is probably far lower than at other ISPs, but it goes to show how ISPs can control their destiny and manage consumption through the use of open and transparent traffic shaping policies. Overall, p2p consumption is 26% of Plusnet traffic across a 24-hour window – the policies are obviously working and people are p2p and usenet downloading when the network is not busy.

Quality and therefore bandwidth bound to increase

Both YouTube and the iPlayer are relatively low-bandwidth solutions compared to broadcast quality shows either in SD (standard definition) or HD (high-definition), however applications are emerging which are real headache material for the ISPs.

The most interesting emerging application is the Move Networks media player. This player is already in use by Fox, ABC, ESPN, Discovery and Televisa — amongst others. In the UK, it is currently only used by ChannelBee, which is a new online channel launched by Tim Lovejoy of Soccer AM fame.

The interesting part of the Move Networks technology is dynamic adjustment of the bit-rate according to the quality of the connection. Also, it does not seem to suffer from the buffering “feature��? that unfortunately seems to be part of the YouTube experience. Move Networks achieve this by installing a client in the form of a browser plug-in which switches the video stream according to the connection much in the same way as the TCP protocol works. We have regularly streamed content at 1.5Mbps which is good enough to view on a big widescreen TV and is indistinguishable to the naked eye from broadcast TV.

Unlike Akamai there is no secret sauce in the Move Networks technology and we expect other Media Players to start to use similar features — after all every content owner wants the best possible experience for viewers.

Clearing the rights

The amount of iPlayer content is also increasing: Wimbledon coverage was available for the first time and upcoming is the Beijing Olympics and the British Golf Open. We also expect that the BBC will eventually get permission to make available content outside of the iPlayer 7-day window. The clearing of rights for the BBC’s vast archive will take many years, but slowly but surely more and more content will be available. This is true for all major broadcasters in the UK and the rest of the world.

YouTube to shrink in importance

It will be extremely interesting to see how YouTube responds to the challenge of the traditional broadcasters — personally we can’t see a future where YouTube market share is anywhere near its current level. We believe watching User Generated Content, free of copyright, will always be a niche market.

Online Video Distribution and the associated economics is a key area of study for the Telco 2.0 team. 

Full Article: BBC’s iPlayer nukes “all you can eat” ISP business model

The UK’s largest broadcaster finally launched its online video streaming and download service on Christmas Day. Plusnet, a small ISP owned by BT,  has provided a preliminary analysis of the traffic and the results should send shivers down the spine of any ISP currently offering an unlimited “all-you-eat” service.

The iPlayer service is basically a 7-day catch-up service which enables people who missed and didn’t record a broadcast to watch the programme at their leisure on a PC connected to the internet. The iPlayer differs from any other internet-based video service in certain key respects:

It is funded by the £135.50 annual licence fee which pays for the majority of BBC activities.

  1. The BBC collected 25.1m licence fees in 2006/7. No advertising is required for the iPlayer business model to work.
  2. It is heavily promoted on the BBC broadcast TV channels. The BBC had a 42.6% share of overall UK viewing in 2006/7 and therefore a lot of people already know about the existence of the iPlayer after one month of launch.
  3. it is a high quality service and is designed for watching whole programmes rather than consumption of small vignettes.

This is sharp contrast to the current #1 streaming site, YouTube.

A massive rise in costs

The key outputs from the Plusnet data is that in January:

  1. more customers are streaming;
  2. streamers are using more; and most importantly
  3. peak usage is being pushed up

This equates for Plusnet to streaming cost increasing in total to £51.7k/month from £17.2k, or an increase of 18.3p/user from 6.1p/user. This is a 200% cost increase in just the first MONTH of the service. If we assume that the Plusnet base of 282k customers is a representative sample of the whole UK internet universe than we can draw some interesting conclusions about the overall impact of the iPlayer on the UK internet. On the whole UK IPstream base of 8.5m the introduction of the iPlayer would equate to an increase in costs to £1.5m in January from 500k.

Despite access unbundling, ‘middle mile’ costs remain a key bottleneck

IPstream is a wholesale product from BT, with BT being being responsible for the transit of the data from the customer’s home to an interconnect point of the ISP’s choice. The ISP pays for bandwidth capacity at the point of interconnect. BT Retail acts like an external ISP in the structurally separated model. The overall effect of the iPlayer for the BT’s IPstream-based customers is roughly neutral, with the increase in revenues at wholesale (external base of 4.2m customers) being offset by the increase in costs at BT Retail (total base of 4.2m customers). Of course, this assumes no bandwidth overages at BT Retail, which probably is not the case as both BT and Plusnet have bandwidth caps. In effect, incremental cost for ISPs using the IPstream product is determined by ordering extra BT IPstream pipes which come in 155-meg bit size chunks. The option for the ISP is either to allow a degradation in performance or order more capacity.

Time to buy more pipes

We tested the bandwidth profile using Wireshark watching a 59mins documentary celebrating the 50 year anniversary of Sputnik with both streaming and P2P. The streaming traffic is easy to analyse as it comes through on port 1935, which is the port used by Flash for streaming. Basically a jitter-free screening ran on average at around 0.5Mbit/sec. Using the 155-meg ordering slice this means only around 300 people need to be watching the iPlayer at the same time (peak = 8pm-10pm) to fill a pipe. Seeing that IPstream customers are aggregated across the UK to a single point, a lot of ISPs will be thinking of the need to order extra capacity. The BBC also offers a P2P download which is of higher quality than the streaming. We managed to download the 500Mb file in just over 20 minutes at an average speed of 3.5Mbit/sec. The total traffic (including overhead) for the streaming was 231MB and for the P2P delivery was 544Mb.

Full unbundling still leaves ISPs at the mercy of backhaul costs

The story for facility-based LLU(Local Loop Unbundling) players, which account for another 3.7m UK broadband customers, is slightly different as it depends completely on network design and distribution of the base across the exchanges. Telco 2.0 market intelligence says that some unbundlers have ordered 1-gig links for the backhaul and should be unaffected least in the short term. However, some unbundlers have only ordered 100-meg links and could be in deep trouble with peak hour people really noticing the difference in experience. The only real option for these unbundlers is to order extra capacity on their backhaul links which could be extremely expensive. The average speed for someone just browsing and doing emails is quite low compared to someone sat back watching videos stream.

Cable companies understand sending telly over wires

The story for Virgin Media, which is the main UK cable operator with 3.3m broadband subscribers, is again is dependent on network design. This time it depends upon the load on the UBR(Universal Broadband Router) within the network segment. Virgin Media have a special angle to this as the iPlayer will be coming to their Video-on-Demand service in the spring, and therefore we assume this will take a lot of load off their IP network. The Virgin VoD service runs on dedicated bandwidth within their network and allows for the content to be watched on TV rather than PC. A big bonus for the Virgin Media subscribers.

Modelling the cost impact

For both cable and LLU players the cost profile is radically different to IPstream players, and it is not a trivial task to calculate the impact. However, we can extrapolate the Plusnet traffic figures to note the effect in volumes of data. We have modelled four scenarios: usage the same as in Jan 2008 (i.e. an average of 19min/month/user) rising to 1 hour/month, 1 hour/week and 1 hour/day. These would give an increase in cost of £1,035k/month, £3,243k/month, £14,053k/month and £98,638k/month respectively for the IPstream industry, only based upon Plusnet cost assumptions. Of course this is assuming the IPstream base stays the same (and they don’t just all go bust straight away!). Across the whole of the UK ISP industry, the increase in traffic (Gb/month) is 1,166, 3,655, 15,837 and 111,161 respectively. That’s a lot of data. The obvious conclusion is that ISP pricing will need to be raised and extra capacity will needed to be added. The data reinforces our belief expressed in our recent Broadband Report that “Video will kill the ISP star”. The problem with the current ISP model is it is like an all you can eat buffet, where one in ten customers eats all the food, one in a hundred takes his chair home too, and one in a thousand unscrews all the fixtures and fittings and loads them into a van as well.

A trigger for industry structural change?

An interesting corollary to the increase in costs for the ISPs is that we believe that the iPlayer will actually speed up consolidation across the industry and make the life of smaller ISPs even more difficult than it is today. Additionally because of the high bandwidth needs of the iPlayer, the long copper lengths in rural England and the lack of cable or LLU competition to the IPstream product, we believe that the iPlayer will increase the digital divide between rural and suburban UK. The iPlayer also poses an interesting question for the legion of UK small businesses who rely on broadband and yet don’t have a full set of telecommunications skills. What do they do about the employee who wants to eat their lunch at their desk whilst simultaneously watching last nights episode of top soap EastEnders?

Time to stop the game of ‘pass the distribution cost parcel’

The BBC is actually in quite a difficult situation, especially as publicity starts to mount over the coming months with users breaking their bandwidth limits and more or more start to get charged for overages. The UK licence payers expect they paid for both content and distribution when they handed over £133.50. In 2006/7, the BBC paid £99.7m for distributing its broadcast TV signal, £42.6m for its radio signal and only £8.8m for its online content. This is out of a total of £3.2bn licence fee income. I would suggest that the easiest way for the BBC to escape the iPlayer conundrum is for them to pay an equitable fee to the ISPs for distributing their content and the ISP plan comes with unlimited BBC content, possibly with a small retail mark-up. The alternative of traffic-shaping your users to death doesn’t seem like a great way of creating high customer satisfaction. The old media saying sums up the situation quite nicely:

“If content is King, then distribution is King Kong”

Full Article: Hidden Potential, France Telecom

France Telecom is showing how to be a classic telco in strange times, with an asset-light take on service integration..

FT is perhaps the archetypal traditional PTT; still part-nationalised, with a dominant position in fixed-line, ISP, and mobile markets at home. During the .com boom, the carrier expanded heavily and ran into debt (it didn’t help that the government hit it up for some cash to meet the requirements of joining the Euro). Meanwhile, the fixed-line voice market began a steady slide as the first alt.telcos, VoIP, and fixed-mobile substitution began to bite. Although the French government was slower than some to take regulatory action, eventually the new regulator ARCEP began to hammer at the de facto monopoly.

So, what did they do about it?

FT’s acquisitions turned out to be better deals than they looked in the smouldering aftermath. Among other things, they had given the company one of the strongest brands in the industry, Orange, a strong ISP in France (Wanadoo), and stakes in global cable backbones and other world-wide presence that permitted them to build strong businesses in bulk IP networking (Opentransit) and enterprise VPNs (Equant). More recently, the company has decided to go all the way, rolling the entire consumer side into Orange.

In terms of a business model, F Tel/Orange is very keen on bundling. As an integrated full-service carrier, it can offer quad-play in France. Interestingly, it’s trying to take advantage of industry horizontalisation to expand this vertically integrated model elsewhere; in the UK, Orange Broadband is providing PSTN and DSL service over Openreach’s wires through local-loop unbundling, and selling GSM/UMTS mobile service along with it as part of a “free broadband? offer. Telco 2.0 readers are of course well aware that “free broadband? really means “compulsory old technology?.

This is an important issue; if it is true that integration means greater market power, there is a lot of money waiting for anyone who can successfully lash disparate elements of the Telco 2.0 world into a virtual carrier. But so far, fancy MVNOs are a notable failure –  you know what we thought at first about Blyk, and Amp’d Mobile crashed and burned, as did ESPN Mobile and Easymobile before them.

The UK’s structural separation model, permitting LLU, means that Orange UK has become an integrated carrier without needing to spend all that money; perhaps not the result Ofcom was aiming for. At the same time, other FT divisions are using the metro-Ethernet lines Orange UK has installed to backhaul its high-traffic cells to serve corporate customers, from behind the Orange name as “Orange Business Services?.

In France, meanwhile, FT is offering IPTV and carrier-VoIP over its DSL network, in a bid to replace the vanishing economic rents from its PSTN business with new service revenues. The key to this effort is the Livebox, the WLAN router/modem/set-top box that is distributed to all subscribers.
