Paper: What Happens when HTTP Adaptive Streaming Players Compete for Bandwidth?

Screen shot 2012-05-01 at 4.06.24 PMThe College of Computing at Georgia Institute of Technology and the Video & Content Platforms Research and Advance Development Division at Cisco have published a white paper on HTTP adaptive streaming. The paper focuses on the problem of competing video players and describes how the typical behavior of an adaptive streaming player in its Steady-State, which includes periods of activity followed by periods of
inactivity (ON-OFF periods), is the main root cause behind three performance problems: player instability, unfairness between players, and bandwidth underutilization.

I haven’t had the chance to read the paper yet and won’t be able to until after my streaming media shows are over, but others are welcome to comment on the paper in the comments section below. The authors have said they welcome any feedback or questions.

Latest CDN Pricing & Volume Data To Be Presented May 14th at The Content Delivery Summit

Default_ConfIn less than two weeks, the fourth annual Content Delivery Summit will take place in NYC on Monday, May 14th. The event will bring together telecom carriers, service providers, content owners, and industry vendors for a detailed look at CDN platforms for the delivery of video and content acceleration.

I've recently completed a CDN pricing survey and collected data from over 500 customers that use content delivery networks for the delivery of video. At the Summit, I will share the latest data collected from the survey along with details on the size of the content delivery market for video, as well as expected growth forecasts for both revenue and traffic volumes.

Attendees will also learn the current pricing points for video delivery services and hear about the market drivers and trends that will determine what customers pay in the future. There will also be an extensive Q&A session, so this is your chance to ask questions pertaining to current or future CDN pricing and market drivers.

The summit will also feature presentations and discussions pertaining to federated CDN, licensed and managed CDN, front-end optimization, transparent caching, optimizing web applications, telco and MSO CDN deployments, build vs. buy, over-the-top video and others.

It's not too late to get a pass for the event and you can use the special registration code of DRF01 and get access to the keynotes, all of the sessions, presentations and networking events for only $295. Register here and put the code DRF01 in the box at the bottom. Twitter hash tag #cdnsummit

Hands-On Review: D-Link’s MovieNite Streaming Player Not Worth Buying

P1010081Over the weekend I picked up the new D-Link MovieNite streaming media player, a $48 box developed in conjunction with Walmart and sold exclusively in their stores and via the Walmart.com website. Of all the streaming media devices I have reviewed and tested, I don't think I've ever told readers not to buy something, until today. For what is suppose to be a very simple player aimed at a non-techie crowd, this player falls far short in just about every category and is not worth the money.

The player supports 1080p video streaming and has 802.11n WiFi, 10/100 ethernet port, HDMI out and composite video connections. The player only supports content from Netflix, Vudu, YouTube and Pandora and has no support to play back local content via USB and no slot for any kind of memory card. While some of those shortcomings would be just fine for someone who only wants to use it to stream movies and TV shows from Netflix and Vudu, I'm afraid even those simple tasks are painful with this player.

The box supports 802.11n, yet no matter what I tried I could not get it to connect to my WiFi network. Another issue is that the name of WiFi networks are cut off, with my network only showing up as two letters in the name, out of seven. Putting in a call to D-Link's tech support number was no help as they couldn't solve the problem. My router sits ten feet from the box, has ten other devices that can connect to it via WiFi, yet the D-Link player kept telling me it could not connect to the network. D-Link support had me reset the box over and over again, with no luck. They then asked me to wait on hold for at least 30 minutes while they "called headquarters", but I declined to wait. On a side note, I know that most companies these days outsource tech support calls to foreign countries to save money, but trying to diagnose a tech issue, with someone who does not speak English fluently, is never a good user experience.

Hoping my WiFi issues were just a software problem that could be resolved with a firmware update, I tried to update the box under the maintenance option, but was given an error message of "Memory space is not enough for upgrade! Do you want to reboot now?" So if you can't download updates for the box, I'm not sure how D-Link expects to ever add fixes and features? For my last option, I actually broke out the printed three page Quick Install Guide in the box, but that was useless. But I did get a good laugh when step three told me not to plug in an ethernet cable if I wanted to use WiFi as the "on-screen setup wizard will allow you to configure your wireless settings". Now I get what they were saying, but if this box is really targeting non-techie's, step four should not be telling you to plug in the power supply when step three is talking about an on-screen setup wizard.

Giving up on trying to connect the box via WiFi I plugged in an ethernet cable which saw my network right away. Since the box only supports four content services, the remote has dedicated buttons for Netflix, Vudu, YouTube and Pandora. The bad news is that the software interface for this box is slow and buggy. Netflix takes nearly twenty seconds to load and videos take much longer to start up when compared with the Roku or WD TV Live player. D-Link does have a note on their website saying that they have released a product software update that resolves issues with streaming content from Netflix, but they don't say what issues they are fixing and there is no way to force download the update.

To get the update on the box D-Link says to "reboot it by powering it off and then back on, wait for the update message to appear, and select ok." Problem is I don't get that message when I reboot it and I have no way to know if that means I already have the update or not. The entire user-experience with this product was not well thought out and it's a really poor interface. I don't know why this box is so slow, but there is a lot of lag time with the software and the box froze on me twice, forcing me to pull the power plug.

Overall, there is nothing to like about this box and consumers would do far better spending $30 more for a Roku HD. And if 1080p isn't required, you can get a Roku LT for the same price as this box, which will also give you hundreds of content channels, instead of only four. The only advantage D-Link's MovieNite box has over Roku is their support for YouTube, something Roku is still missing for some unknown reason.

While I could understand D-Link and Walmart's desire to want to put out a really cheap streaming box in the market for those who just want to stream Netflix and Vudu, it's really pointless when every connected TV, Blu-ray player and streaming box already has Netflix on it. This box really doesn't fill any void in the market and isn't worth buying.

Data Shows Video Accounts For 60% of MSO and ISP Traffic, 50% Of That Comes From Netflix

In a recent discussion with transparent caching provider Qwilt, the company shared with me data from some of their ISP and MSO customers in the U.S. and Europe. At one major MSO in the U.S., 60% of their traffic comes from video content. Netflix makes up 50% of that traffic and also leads in total viewing time.

And from a major ISP in Europe (see charts below), Netflix become the second largest online video service in the UK in under three months. While the BBC iPlayer has the second largest online video volume in the UK, they are currently migrating their platform to HTTP from RTMP which is the reason you don't see them in the top sites graph.

While these numbers should not come as any surprise to those who talk to MSOs, ISPs and carriers, it is further evidence that transparent caching solutions and licensed and managed CDN platforms are starting to play a very crucial role with those who own and operate the last-mile networks.

We'll be discussing and hearing directly from MSOs and carriers on this topic at the Content Delivery Summit next month.
