Apple TV 4K 4th generation adds AV1 and Dolby Vision 8.1

Apple TV 4K 4th generation adds AV1 and Dolby Vision 8.1
The Mac Observer

Apple has released the 4th generation Apple TV 4K, which includes a new A19 chip featuring a dedicated AV1 hardware decoder and support for Dolby Vision Profile 8.1. These updates enable more efficient video compression and broader format compatibility for streaming services that adopt these standards.

Key Takeaways

  • A19 chip includes a dedicated AV1 hardware decoder to reduce bandwidth consumption on slow connections
  • Support for Dolby Vision Profile 8.1 expands compatibility beyond the previous Profile 5 limitation
  • Hardware upgrades include Wi-Fi 7 support and a built-in Gigabit Ethernet port on the 128GB model
  • A19 silicon delivers a 50% CPU performance boost and 2x faster GPU performance over the 3rd generation

Why It Matters

The inclusion of a dedicated AV1 decoder in the Apple TV 4K 4th generation signals a significant shift toward royalty-free, high-efficiency codecs in the premium hardware space. By reducing bandwidth requirements without sacrificing 4K quality, Apple is addressing the infrastructure constraints of global streaming markets and data-capped consumers. This move pressures major streaming platforms to accelerate their AV1 encoding pipelines to take advantage of the new hardware's efficiency. The addition of Dolby Vision Profile 8.1 further ensures the device remains the primary hub for high-fidelity home cinema. Watch for whether Netflix or YouTube announces immediate AV1 support specifically for this new hardware revision.

In short

The Apple TV 4K 4th generation has launched featuring an A19 chip with dedicated AV1 hardware decoding and Dolby Vision Profile 8.1 support. These upgrades allow for higher quality video at lower bitrates, helping users with data caps or slow connections while signaling a shift toward more efficient, royalty-free streaming codecs.
