Would you design a SmartTV that couldn’t play UHD videos from YouTube? Me neither and designers from LG and Samsung apparently agree. I was researching codec support among smart TVs for upcoming training sessions at Streaming Media East and noticed that the 2020 version of the Samsung SmartTV supports AV1 decode. A quick search found an article on Flat Panels HD entitled YouTube now streaming 8K video on 8K TVs with AV1 support, which states:
LG and Samsung’s 2020 8K models are the first TVs to support AV1 hardware decoding. Below you see YouTube 8K (60fps) streaming to an LG 2020 8K LCD TV (NANO95 range). Yesterday, TCL said that its new X915 8K TV will also support YouTube 8K via AV1 but that an update to Android 10 (scheduled for later this year) will be required to enable it. Philips has told FlatpanelsHD that it is committed to AV1, too.
The article also mentions that YouTube videos seen on certain Android TV devices will also display AV1. As explained in this article on xda-developers.com, AV1 playback will likely only be enabled on devices with AV1 hardware.
Most SoCs in use on smartphones and Android TV boxes rely on software decoding for videos encoded in AV1, which can be taxing on the CPU and lead to higher power consumption. On the smartphone side, only the MediaTek Dimensity 1000 is capable of decoding AV1, while only a handful of recent SoCs used in Android TV devices support hardware-accelerated AV1 decoding. Those include Broadcom’s bcm72190/72180 and Realtek’s RTD1311/RTD1319.
AOMedia told us back in 2018 that it would take two-years for hardware-based AV1 decoding to arrive on smartphones and smart TVs and now we’re seeing the first wave. This makes it even more important for producers to be up to speed regarding the latest on codecs and deployments.
Here are additional details regarding my training sessions.
Tuesday, May 26, 11:00 a.m. – 2:00 p.m. ET / 8:00 a.m. – 11:00 a.m. PT
Instructor: Jan Ozer
Description: This course helps those new to streaming media get familiar with the relevant terms, concepts, and technologies. The session begins with a definition of terms like codecs, container formats, and adaptive bitrate streaming, as well as encoding concepts like bitrate control (VBR, CBR) and frame types (I, B, and P). Then it details the key H.264 encoding parameters that impact quality and compatibility. Next up is adaptive streaming, including a review of available ABR technologies like HLS and DASH, how to formulate an encoding ladder, and how to use multiple DRMs to protect premium content. Then we’ll review the technical requirements for ABR delivery to computers, smartphones and tablets, OTT devices, and smart TVs, and finish with a quick look at advanced codecs like HEVC, VP9, AV1, VVC, and LCEVC. You walk away knowing the technical requirements for delivering to all key platforms and an understanding of how to do so.
Wednesday, May 27, 11:00 a.m. – 2:00 p.m. ET / 8:00 a.m. – 11:00 a.m. PT
Instructor: Jan Ozer
Description: This session helps encoding professionals get up-to-speed on crucial encoding-related issues, technologies, and techniques. Topics include:
- The best high-level strategies for delivering to computers, mobile, smart TVs, and OTT (which ABR, codecs, and DRMs are supported by which platforms)
- Current status of the H.264, HEVC, AV1, LCEVC, and VVC codecs; who’s using and where; comparative quality and encoding/decoding performance, and deployment schemas (DASH? HLS?)
- How to deliver HEVC over HLS
- Current status of per-title technologies for VOD and live encoding
- How to build/analyze your encoding ladder using objective quality metrics
- Current status of CMAF and its implications for delivering a single set of files to HLS/DASH players
- How to encode/deliver/protect with dynamic and static packaging
