On all my other devices from Amazon 4K Firecube 2nd Generation and Nvidia Shield Pro 2019 device and even my LG 2019 TV has the far better and much more advanced newer Netflix app .. I paid a lot of money to have the finest "so called" streamer on the market and we seem to have a older and very bad quality Netflix app with Tvos 16.. I mean the tagging is all over the place and the newer app is far better and all-rounder better customer experience??? Apple come on get with the program all your direct competitors of bang up today or is that their all Android based and they are much superior to Apple TV Os ????
Blimey they don't like Apple very much then !.. personally I don't like Apple either not for me at all ..very nice looking devices but that about as far as it goes for me . I'm an android nerd for life lol and they have such open sources as well apple in their own little world.
Okay then I try and ask Netflix why it feels like a 3rd rate app compared to all the other devices on the market and I have the newest Apple 4K TV device 128GB edition to get the very best in streaming quality but I'm now wondering if that been a mistake I may think about selling it and grabbing the newer Amazon 4K Firefube instead later on in the year .
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.
first off 1080i and 720p are the same but I would go with 720p because it is better. Second Netflix and all hd tv is only 720p (1080i). and for picture quality it all comes down to your connection speed.
This is where the streaming revolution comes in. Smart TVs and streaming devices give access to apps such as Netflix, Prime Video, Disney Plus and more, meaning people can watch millions of hours of movies and TV shows, in up to 4K, for set monthly fees, which ends up being significantly cheaper, and tidier, than buying hundreds of Blu-rays.
So it begs the question: why would people bother with physical media such as 4K Blu-ray anymore? As someone with experience in AV retail and now a tester of TVs, I knew there was a quality difference so I decided to check it out for myself and the results were surprising.
For these tests, I used the Panasonic UB154, a budget 4K Blu-ray player and the Panasonic DP-UB820, a mid-range 4K Blu-ray player connected to the Panasonic MZ1500, a mid-range OLED TV, which was set to Filmmaker or Cinema picture mode, and watched the same movies on both Blu-ray and streaming.
Beginning with John Wick 4, I immediately ran into some trouble. Advertised as 4K on Prime Video, I could not get it to stream anything higher than HD (after some research I discovered I was not alone) so I opted for HD quality vs standard Blu-ray.
Moving on to Godzilla vs Kong, again in 1080p HD on Netflix vs standard Blu-ray, and it was the same story. The Netflix version looked better than I expected, carrying a lot of the vivid, colorful punch on the neon signs in Tokyo that was on the Blu-ray version but again the Blu-ray version showed deeper black levels and more refined details and textures. I was still, however, impressed with how good the streaming version looked.
Finally, I managed to test a 4K Blu-ray vs a 4K stream in the fantastic re-master of Alien, which was on Disney Plus. In both versions, black levels and contrast were superb, capturing the eerie, doom-laden nature of the movie well. Textures were again sharp on both versions. Although there was that little bit more perceived definition in the 4K Blu-ray. Skin tones, for example, looked accurate on both, but more so on the 4K Blu-ray. It is worth noting that the Disney Plus version was in HDR10, whereas the Blu-ray version was in HDR10+, which gave the Blu-ray the perception of a clearer picture.
Whether it was the UB820 or UB154, Blu-ray did indeed have better picture quality overall thanks to 4K upscaling and performance, but the comparison between them and streaming was closer than anticipated.
After being surprised by picture quality comparisons, sound was the next logical test. Running the Panasonic MZ1500 through a Sonos Beam (Gen 2) soundbar, one of the best soundbars at a mid-range price, I tested the same movies again. This time, the difference made itself known.
