Multi-Codec World is here and now Two years ago we published the blog post “Get ready for a multi-codec world”. With the official launch of H.266 (VVC) and the progression of future codecs like AV1 and VP9, it’s a good time to revisit the state of the multi-codec world, and why it’s important to your…
Super-Resolution: Why is it good and how can you incorporate it? Introduction Welcome to Part 2 of Bitmovin’s Video Tech Deep Dive series: Super-Resolution with Machine learning. Before you get started, I highly recommend that you read Part 1. But if you would rather prefer to directly jump into it, here is a quick summary: …
This blog post is continuation of an ongoing blog and webinar technical deep series. You can find the first blog post here. The first post covered the fundamentals of live low latency and defined chunked delivery methods with CMAF. This blog post expands on chunked CMAF delivery by explaining it’s application with MPEG-DASH to achieve low…
In the day and age of online streaming, Google Chromecast is probably the most affordable living room OTT solution on the market. Google originally introduced the dongle with the intent to connect phone apps to a not so “Smart” TVs back in the day, so users can stream content from their phones onto a larger…
In the previous series of posts, we set a baseline of compression knowledge by defining how lossy compression algorithms work for images and breaking down the JPEG image standard. Now that we’ve covered our image compression basics, it’s time to move up to the next level with video -as you might have guessed – a…
What is Live Low Latency? Low Latency in live streaming is the time delay between an event’s content being captured at one end of the media delivery chain and played out to a user at the other end. Consider a goal scored at a football game: Live latency is the delay in time between the…
One of the first questions when starting with adaptive streaming formats such as MPEG-DASH or HLS is how long do you generate the used media segments of the content. The segmentation of the content is necessary, as this enables the switching between the different video/audio qualities during the streaming session. The following figure gives a short…
Everyone knows what a jpeg is! It’s an image of course. Yes and No – JPEG is the acronym that sits at the end of your picture file on your favorite device. You must be thinking, “Hold on one second, if it’s not the actual image, and it’s an acronym, what is it and what…
This scientific evaluation puts AV1 to the test against industry standard codecs and shows that AV1 is able to outperform VP9 and even HEVC by up to 40% Introduction For practical Over-the-top (OTT) streaming applications it is mostly necessary to supply streams using multiple different video codec standards in order to stream to a wide…
This is a comprehensive and detailed guide to Lossy Compression algorithms. Here you will find everything a developer needs to know about this cutting-edge topic, in a a guide created by some of the most advanced video technology experts and engineers. Take your time to read through the whole resource, or just skip to the…
