HomePod Firmware Possibly Reveals Apple Watch With LTE and 4K Apple TV With HDR10 and Dolby Vision

iOS developer Guilherme Rambo‏ has discovered a anxiety to a 4K HDR arrangement mode in a HomePod’s firmware, lending faith to rumors that Apple is contrast a fifth-generation Apple TV able of streaming 4K fortitude video.


HomePod doesn’t have a display, and iOS inclination miss a fortitude for local 4K playback, so a find expected pertains to a Apple TV.

Rambo also detected strings kCADisplayModeDolby and kCADisplayModeHDR10, suggesting that a 4K Apple TV could support both a Dolby Vision and HDR10 tone formats for high-dynamic-range video.

Apple has also listed name cinema as 4K and HDR in iTunes squeeze history, during slightest in Canada and a United Kingdom. The calm is still usually playable in customary clarification or HD, that varies from 720p to 1080p, though Apple could be scheming to offer iTunes calm in 4K HDR for a new Apple TV.

Another developer Jeffrey Grossman‏ also spotted a probable anxiety to an Apple Watch with LTE support. The string, that refers to GizmoPreservingeSIM, lends faith to a news yesterday that claimed Apple Watch Series 3 models will underline mobile connectivity for use though a interconnected iPhone.

The applicable bit of that fibre is a discuss of a SIM, as a Apple Watch Series 3 would presumably have an embedded SIM label if it had mobile connectivity. Another fibre mentions GizmoRadioBundleIdentifier, that could impute to a Apple Watch Series 3’s mobile radio, reportedly to be granted by Intel.

For those unaware, in 2015, The New York Times reported a Apple Watch was codenamed Gizmo internally.

Inside Apple, members of a group that worked on a watch product, code-named Gizmo, contend it was a formidable engineering challenge.

The Gift That Keeps on Giving

Last week, Apple seeded an over-the-air firmware record for a HomePod, divulgence that it will run a somewhat mutated chronicle of iOS. The pre-release program is pronounced to conform with iOS 11.0.2, and it contains references to several unreleased facilities that would routinely be redacted before a open release.


The firmware contains a cargo that can be unpacked into a filesystem regulating a few developer tools, giving anyone learned adequate a ability to hunt by thousands of strings in a program regulating Terminal commands and disassembly apps like Hopper. For a past 8 days, that’s accurately what’s happened.

Since a HomePod firmware is formed on a full iOS stack, many discoveries have been done not usually about a intelligent speaker, though also potentially about a supposed iPhone 8, Apple TV, and Apple Watch.

Thanks to a HomePod firmware, we know that that a iPhone 8’s front camera might record 4K video during 60 FPS, and that a infrared facial approval capabilities might work with Apple Pay. The firmware also suggested a glyph of an iPhone 8 with a full-front arrangement with a nick during a tip for a earpiece and sensors.

As for a HomePod itself, it’s been detected that a intelligent speaker’s multi-color LED waveform manifest when interacting with Siri measures in during 272×340 pixels. HomePod also appears to have 1GB of RAM, and some of a speaker’s sound effects were found buried in a firmware.

HomePod doesn’t launch until December, so a firmware was expected expelled by accident, underneath a identifier AudioAccessory1,1.


Update: MacRumors detected a fibre J105a in a HomePod firmware, unchanging with a fifth-generation Apple TV’s inner codename initial suggested by Bloomberg contributor Mark Gurman in February.
