This is a well-established approach for OTT streaming applications. Since the main focus is on an HTTP Adaptive Streaming (HAS) dataset, we adopted a set of bitrate/resolution pairs – referred to as the bitrate ladder – with a range from very low bitrates/resolutions of 100 kbits at 256×144 pixels up to 4k resolutions at 20 megabits.

For an in-depth description of the dataset, please reference ( ). The full dataset is freely available online ( ). The multi-codec dataset presented here adopts the aforementioned standards in a practical OTT adaptive streaming scenario. Another key difference between the codecs is that VP9 and AV1 were developed with the goal of being open source and freely available for anybody to implement and use without any royalties while AVC and HEVC require a royalty to be paid. While AVC offers the best compatibility across devices and platforms, the newer standards such as HEVC and AV1 offer a much higher compression efficiency and thereby also a better user experience. With the standardization of AV1, another modern video coding standard is joining in. The most commonly used video codes in this scenario are AVC, VP9 and HEVC. 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% Introductionįor 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 range of devices and platforms.
