The Customer is Always King (Well, until They Use Too Much Data)
April 7th, 2011 by Dave Gibbons [No Comments]We have predicted the current capacity crunch for some time and over the past months we have seen almost every wireless operator around the world begin to cap their users on a monthly basis. This all to contain the damage of streaming video.
But the fact that wireline operators are now capping their consumers and willing to jeopardize something as important as customer satisfaction demonstrates exactly how dire the situation has become. AT&T in the US and Rogers in Canada have now announced caps on DSL and Cable.
Consider, for example, that Netflix is cutting the quality of streaming video in Canada and that Verizon is planning to “throttle” its most-active users when its network is stressed. They are trying to find a solution to a very complicated problem, which is commendable, but is it really wise to further diminish an already poor quality of experience for the customer? For sure the data cap will help as a band aid to their network capacity crunch but operators and media distributors alike must find new technologies that work for both sides.
So how can operators mitigate the impact capacity crunch without sacrificing the consumer experience? Unfortunately there isn’t a silver bullet. There is not a solution or tool on the market today that can single-handedly solve the capacity crunch. But there is some good news – there are a number of video delivery optimization solutions on the market today that can help ease the burden that mobile video places on the network.
Operators just need to be more realistic when they are evaluating them. For example, solutions that rely on bit-rate throttling or transcoding are akin to putting a bandaid on a shotgun wound. Sure, they reduce the amount of data flowing over the network, but it’s a relatively insignificant reduction that also often results in a poor end user experience.
Why not instead consider employing a strategy such as content pre-positioning, which provides consumers with a far superior playback experience on their device and maximizes the efficiency of the operators’ networks by leveraging underutilized capacity and flattening the peak loads. And it also enables innovative revenue growth applications that work outside of the cap.
It’s a win-win solution, in our opinion. The customers get great quality playback on an unlimited basis, operators get to save their networks and don’t need to invest billions so that media companies can monetize it and media companies continue to grow in the digital content distribution market.

Off-Hour WiFi Offload: Capacity Crunch Silver Bullet?
March 4th, 2011 by Jeff Harrang [No Comments]There has been much discussion recently about the merits of off-hour WiFi offload.
As mentioned in this recent Computerworld article, “Sony, SanDisk and several other technology providers have formed a group and proposed a standard that would use predictive software to pre-load content onto mobile devices in order to preempt buffering issue due to bandwidth bottlenecks.”
Sounds promising, right? But how exactly are these providers planning to “pre-load content?” After digging a little bit deeper, it became apparent that they were planning to use a technique called off-hour WiFi offloading, which at first glance might seem comparable to content pre-positioning, which is utilized by our NetRover platform.
After a quick comparison, however, several significant differences between the two technologies emerge. While both concepts aim to deliver content to a mobile device without burdening the network, consider the following:
- For off-hour WiFi offloading to work, there a multitude of requirements, including the availability of a WiFi network, the proper configuration of device settings and adequate smartphone battery life.
- In addition, latency is a significant issue as content cannot be delivered until the network provides a window of opportunity. Many times, this means that content is not being delivered until the wee hours of the morning.
- Many wireless operators do not own WiFi networks. So selling consumers on new video-based services that require them not to work on their mobile networks is a hard sale. Wireless operators and consumers need media to work on 3G (and 4G) networks – not restrict it only to WiFi.
This stands in stark contrast to NetRover’s content pre-positioning technology, which “roves” the network day and night to identify and utilize surplus capacity. In general, content pre-positioning is far more flexible than off-hour WiFi offloading as it is not dependant on WiFi and does not rely on a preconfigured schedule for content delivery.
Rather, content pre-positioning works on WiFi and 3G and continually works with the network to deliver content any time surplus capacity is identified. No preconfigured schedule required.
We think users need mobile video delivery technologies that actually make life easier, not ones that mandate a plethora of requirements in order to work. What do you think?
Part 2: Providing High-Quality Video Outside of the Mobile Data Caps
November 5th, 2010 by Dave Gibbons [1 Comment]In my opinion, the end-user mobile video experience today leaves a lot to be desired. On any given day, I will visit an app for a leading cable news site on my iPhone. Half of the time I wind up watching a video of decent quality, and half of the time, I get a video that freezes and buffers until I get frustrated and exit the app. At best, the experience is mediocre.
Personally, I think this is unacceptable, and it looks like the majority of mobile video users today agree. In fact, we expect that over time, consumers will migrate to those applications that provide better experience for their “video snacking” time and even premium video.
It is essential, therefore, for content owners to provide consumers with a better experience just to stay competitive. One way to improve QoE and gain a strong competitive advantage is to enable apps with content pre-positioning technology. Apps that utilize this exciting new technology eliminate consumer frustration by pre-positioning content into the end device memory using surplus capacity. This allows content to be played back instantly, truly at any time (on an airplane, etc.) and with ultimate consistent quality.
We believe that pre-positioning technology, which is utilized by Opanga’s NetRover solution, can complement subscriber data usage limits and pricing plans that are becoming the norm today (see previous post). For example, content pre-positioning can enable operators to offer new innovative revenue growth applications that are “outside of the cap,” and, when done properly, can maximize the efficiency of the operators’ networks by leveraging underutilized capacity. This is in addition to providing consumers with a far superior playback experience on their device. Consider, for example, the following possible use cases:
- Premium content distribution such as catch-up TV, Seasons Pass TV and “mobile DVR” functionality.
- New release VOD movie content delivered to smartphones that coincide with DVD and Blu-Ray release windows.
- Up-to-date news applications, where subscribers can open an app and watch all of the latest local or national news videos – without a broadband connection
- Personal file sharing, where subscribers can share sharing pictures and media with other devices or family members
What other use cases can you imagine with business use cases? What is your favorite video-based app?
Part 1: Data Caps: Good for the Consumer or Good for the Operator?
October 29th, 2010 by Dave Gibbons [1 Comment]AT&T and Verizon are doing it. And it is only a matter of time before all wireless operators are imposing some type of usage-based mobile data pricing, or data caps. The iPhone, surge of Android devices and now tablets are demanding an unprecedented amount of wireless bandwidth largely due to video-based apps. And bandwidth is something that operators have a limited amount of.
So data caps are here to stay (even with 4G, we believe) because operators simply cannot keep up with the growing demand of video, which uses a tremendous amount of capacity. Read more about how much capacity streaming video requires.
It has been argued that data caps are good for the operator (less network congestion so they can add more subscribers without building new base stations as quickly) and good for some subscribers as well (especially light users).
But how do you know how much data you use?
We did the math on AT&T’s pricing plan and we determined on average subscribers pay about 5¢ per MB. This is fairly meaningless unless you know how much data you can get per MB.

No doubt subscribers will now have to think twice before viewing that 2 minute YouTube video, not to mention longer-form content that is proving popular on these devices. I’d argue that this is not good for content owners or over-the-top type of video service providers.
We believe operators are faced with two primary options:
1) Forget about allowing subscribers to stream video over 3G
2) Find alternative ways for subscribers to get their video fix
If you’ve read this blog before, you know that Opanga has developed solutions based on a concept called content pre-positioning. Operators can pre-position content into end devices by using surplus capacity found in their networks throughout a 24-hour period.
We believe that pre-positioning technology can complement subscriber data usage limits and pricing plans. Content pre-positioning can enable operators to offer new innovative revenue growth applications that are “outside the cap.”
Stay tuned for some business use cases that will benefit operators and media companies.
Are you surprised at how much a movie would cost on your smartphone? Would you pay it?

So What Exactly is Content Pre-Positioning?
September 20th, 2010 by John Burnette [1 Comment]Posted by John Burnette
Earlier this summer, FierceWireless posted an incredibly timely and relevant article entitled: “Mobile video traffic: Alleviating the capacity crunch.” The article was excellent summary of all of the solutions available to operators to handle the massive strain placed on their networks from video services, with one notable exception: it does not mention content pre-positioning.
It’s understandable why Content Prepositioning wasn’t included. While adaptive streaming, bit-rate throttling, transcoding and optimization techniques, and smart caching have been around for quite some time, Content Prepositioning is a relatively new and sophisticated concept. So what exactly is Content Prepositioning and how does it compare to these other technologies?
Simply put, Content Prepositioning enables smarter networks to deliver better video by pre-loading content to the end user device before the moment of playback. Because the content is locally rendered, playback starts instantly, never freezes and does not depend on a live broadband connection. Unlike approaches that use adaptive streaming, bit-rate throttling, trickling, or transporting and optimization techniques, Opanga’s unique Content Prepositioning technology only uses surplus capacity to ensure that video delivery does not add to the existing network congestion. The bottom line? Content Prepositioning can help save the operator’s networks while providing a vastly superior consumer wireless video experience.
We think that Content Prepositioning is an essential technology to augment existing techniques and technologies and we are proud to be pioneering the concept. What do you think? We would love to hear your thoughts, so please feel free to chime in with comments.
Understanding the Capacity Crunch & the Necessity of Smarter Networks
September 2nd, 2010 by Jeff Harrang [2 Comments]There is no doubt that video will drive revenue growth and innovation for wireless services in the future. But there is a fundamental mismatch between the amount of spectrum available on the planet and the demand that streaming video places on that spectrum. Let’s discuss why.
Streaming video technology is not scalable due to its inherently degrading effect on the networks and inconsistent user quality. Consider that the amount of capacity (the continuous bit rate) required for streaming video is determined by the quality of the video playback to be delivered and the resolution of the rendition – the screen size. A true HD stream to a large flat screen TV requires tens of megabits per second whereas a video stream to a small Smartphone screen with reasonable minimum playback quality can be as low as 300kbps.
In contrast, voice services and SMS services use a fraction of the bandwidth consumed by streaming video. The table below compares the bandwidth consumption for various wireless applications over a typical session duration.
Pretty sobering figures, especially when you consider that streaming services typically don’t generate any additional revenue for the operators. Opanga has been working with wireless operators to help them create smarter networks and distribute better quality video by prepositioning content— all without deploying substantial new capital equipment.
In the next few weeks, we will be sharing with you exactly how we are doing this, but in the meantime, we want to know what you think. Is streaming a long term viable business proposition? What do you feel are better ways to distribute video over broadband wireless networks?
