I am new to multiple Rokus. We are moving into new house and I have purchased Rokus for each room. When setting them up I understand that I can have them all connect to a single account or I can create individual accounts for each?
Even your Roku devices are connected to a single account, you can still view or watch different channels/contents at the same time. The purpose of linking them to just one account is to make sure that you won't be double-billed for any subscription that you will sign up for.
@iwasbutter1st, in addition to what @Strega said, if your subscriptions to the various streaming providers are directly with the provider and not through Roku then it doesn't matter what Roku account your devices are linked to.
If you've already set up the devices then you can verify the Roku account on each one by going to Settings->System->About and viewing the email address. You can also see what devices are linked to a Roku account by going to and scrolling down to "My linked devices". There is no way to change the Roku account on a device other than factory resetting the device.
I pulled this chapter together from dozens of sources that were at times somewhat contradictory. Facts on the ground change over time and depend who is telling the story and what audience they're addressing. I tried to create as coherent a narrative as I could. If there are any errors I'd be more than happy to fix them. Keep in mind this article is not a technical deep dive. It's a big picture type article. For example, I don't mention the word microservice even once :-)
Given our discussion in the What is Cloud Computing? chapter, you might expect Netflix to serve video using AWS. Press play in a Netflix application and video stored in S3 would be streamed from S3, over the internet, directly to your device.
Another relevant factoid is Netflix is subscription based. Members pay Netflix monthly and can cancel at any time. When you press play to chill on Netflix, it had better work. Unhappy members unsubscribe.
The client is the user interface on any device used to browse and play Netflix videos. It could be an app on your iPhone, a website on your desktop computer, or even an app on your Smart TV. Netflix controls each and every client for each and every device.
Everything that happens before you hit play happens in the backend, which runs in AWS. That includes things like preparing all new incoming video and handling requests from all apps, websites, TVs, and other devices.
In 2007 Netflix introduced their streaming video-on-demand service that allowed subscribers to stream television series and films via the Netflix website on personal computers, or the Netflix software on a variety of supported platforms, including smartphones and tablets, digital media players, video game consoles, and smart TVs.
Netflix succeeded. Netflix certainly executed well, but they were late to the game, and that helped them. By 2007 the internet was fast enough and cheap enough to support streaming video services. That was never the case before. The addition of fast, low-cost mobile bandwidth and the introduction of powerful mobile devices like smart phones and tablets, has made it easier and cheaper for anyone to stream video at any time from anywhere. Timing is everything.
Building out a datacenter is a lot of work. Ordering equipment takes a long time. Installing and getting all the equipment working takes a long time. And as soon they got everything working they would run out of capacity, and the whole process had to start over again.
The long lead times for equipment forced Netflix to adopt what is known as a vertical scaling strategy. Netflix made big programs that ran on big computers. This approach is called building a monolith. One program did everything.
What Netflix was good at was delivering video to their members. Netflix would rather concentrate on getting better at delivering video rather than getting better at building datacenters. Building datacenters was not a competitive advantage for Netflix, delivering video is.
It took more than eight years for Netflix to complete the process of moving from their own datacenters to AWS. During that period Netflix grew its number of streaming customers eightfold. Netflix now runs on several hundred thousand EC2 instances.
The advantage of having three regions is that any one region can fail, and the other regions will step in handle all the members in the failed region. When a region fails, Netflix calls this evacuating a region.
The header image is meant to intrigue you, to draw you into selecting a video. The idea is the more compelling the header image, the more likely you are to watch a video. And the more videos you watch, the less likely you are to unsubscribe from Netflix.
The first thing Netflix does is spend a lot of time validating the video. It looks for digital artifacts, color changes, or missing frames that may have been caused by previous transcoding attempts or data transmission problems.
A pipeline is simply a series of steps data is put through to make it ready for use, much like an assembly line in a factory. More than 70 different pieces of software have a hand in creating every video.
The idea behind a CDN is simple: put video as close as possible to users by spreading computers throughout the world. When a user wants to watch a video, find the nearest computer with the video on it and stream to the device from there.
In 2007, when Netflix debuted its new streaming service, it had 36 million members in 50 countries, watching more than a billion hours of video each month, streaming multiple terabits of content per second.
At the same time, Netflix was also devoting a lot of effort into all the AWS services we talked about earlier. Netflix calls the services in AWS its control plane. Control plane is a telecommunications term identifying the part of the system that controls everything else. In your body, your brain is the control plane; it controls everything else.
In 2011, Netflix realized at its scale it needed a dedicated CDN solution to maximize network efficiency. Video distribution is a core competency for Netflix and could be a huge competitive advantage.
The number of OCAs on a site depends on how reliable Netflix wants the site to be, the amount of Netflix traffic (bandwidth) that is delivered from that site, and the percentage of traffic a site allows to be streamed.
Within a location, a popular video like House of Cards is copied to many different OCAs. The more popular a video, the more servers it will be copied to. Why? If there was only one copy of a very popular video, streaming the video to members would overwhelm the server. As they say, many hands make light work.
Right now, up to 100% of Netflix content is being served from within ISP networks. This reduces costs by relieving internet congestion for ISPs. At the same time, Netflix members experience a high-quality viewing experience. And network performance improves for everyone.
What may not be immediately obvious is that the OCAs are independent of each other. OCAs act as self-sufficient video-serving archipelagos. Members streaming from one OCA are not affected when other OCAs fail.
It will see it through the chromecast app, I can stream to it through youtube. BUt once I enter the netflix application and hit the chromecast button it does not see any chromecasts. Wierdly it does see a couple roku's and an xbox.
I've run into this exact weirdness on campus. Each of the past 5 chromecast setups were for someone using an iPhone and all 5 of them wouldn't work with Netflix, but Hulu, youtube, etc... everything else works. That and the Andriod Netflix for the same Chromecast works fine. Any chrome browser as well running netflix.
I spent time searching through every blocked airgroup service I could and still not sure. I'm surprised there doesn't seem to be more people with this issue. It works perfectly on an Andriod - and just fine for the students at home on the same two devices.
I editted my post until I could do some additional testing.. We just upgraded to ArubaOS 6.5.1.(4) from 6.4.3.(10) and IOS chromecast support has gotten worse. While I can still see the chromecast in Google Home, now I can't see it in YouTube where I could previously. I can cast from Chrome on MacOS and Windows, and Android can access it with all Apps, but nothing now from IOS. Does anyone have an active TAC call open on this or should I pursue it?

Rumors are getting stronger that Netflix is "cracking down" on password sharing, so if you're currently password sharing and don't own the account, you might soon need to go through Netflix's new user experience; where you register your account, and then some more stuff happens, too. It has been covered extensively elsewhere how attractive it is for Netflix to address password sharing, so here instead I will be covering the new user experience.
That new user experience (NUX) is a driver of retention, which in turn is a key metric for subscription businesses like Netflix (see here). It's also an area where product and marketing intersect, a favourite of mine. Plus, it's timely and useful inspiration for the SVOD products that I work on. Therefore, I got curious after the NUX's of Streamers.
So I decided to dive in and sign up for Netflix, and record the experience. In the near future I plan to review more streamer NUX's, but it makes sense to start with the experience of the Streamer that pretty much defined SVOD; Netflix.
- Time-to-value: about 3 minutes. This is the time it takes between Googling for 'netflix' and viewing the first video on Netflix
- There are two parts to the NUX, chapters if you will; "For The Business" and "For The Viewer". "For The Business" is basically about the streamer getting paid. "For The Viewer" is about gathering information to improve the Netflix experience for the newly subscribed user, mostly by enabling personalization
- There's a minor 'blooper' in "For The Business", where Netflix indicates that there are 3 steps. However, Step 2 never appears. Instead, there are two steps that are both called Step 1, and Step 2 is skipped
- Both "For The Business" and "For The Viewer" are designed as separate set of steps. This may lead you to believe that you are done signing up after the three steps of "For The Business", but then the next set of steps presents itself. It might be that "For The Viewer" is optional, meaning that you're able to login to Netflix if you drop out of that flow. But it's not presented as such. I also wonder whether separate teams maintain both sets of steps
- In "For The Viewer", Netflix explains well why you should bother providing the requested information to them, with the goal of audio and subtitles in the desired language(s) and setting up personal profiles to enable recommendations tailored to each profile. Netflix asks the user to invest time NOW, to make your experience with Netflix better LATER. I think that in each case, the benefit outweighs the investment, however do note that it lengthens TTV
- When you consider adding something to the NUX that lengthens TTV, ask if you can get that info at a later stage. Asking too much upfront, might result in the user second-guessing if it's worth effort. Convince of value first, then get to invest some more, to get some more value next time, in a value-investment spiral upwards
