Your eyes don’t deceive you - that tiny chip says ARM. What could all of those resistors be for? Smaller than anything we’ve seen, electronics-wise. You would not believe how incredibly tiny those components are on the left. It seems unlikely, doesn’t it? So out came the hacksaw. “You mean to tell me there’s enough electronics in that tiny plug to support AirPlay streaming and decoding?” It’s in no way passing raw HDMI out from the device, but rather presenting said stream upscaled to 1080p.
It must somehow set up a connection with the very iOS device it’s plugged into. I don’t mean AirPlay the network protocol, but rather AirPlay the video compression system. Is the Lightning Digital AV Adapter basically a small AirPlay-like receiver? You got it. After some good Twitter leads, and a little digging, we had our theory: Hang on, these are the same things we experience when we stream video from an iOS device to an Apple TV… This is just an AV adapter! Why are these things happening! Limited resolution. (We don’t get these artifacts with the old AV adapter.) Theory Not exactly the cleanest text in the universe! Look at all that edge garbage. Right?īut not with the Lightning Digital AV Adapter: When you plug a device into a television, you expect a clean, crisp signal - a mirror of what you see on the screen. Maybe they mean that the adapter upscales the 1600 × 900 image to 1080p? Mystery #2: MPEG Artifacts Questionably, Apple’s iPad mini tech specs claim “up to 1080p” video out support, but we can’t figure out how that’s possible. When we plug in the old Dock Connector AV Adapter, the system gives us the 1920 x 1080: “Hang on, that’s not 1080p!”, you’re saying to yourself. When we turn on “Video Mirroring” to send out an image through the Lightning AV Adapter, the system tells us that the maximum and optimum resolution we can do is 1600 × 900: (Chung-chung!) Mystery #1: 1600 × 900 Resolution, Tops In doing so, we waded right in the middle of a strange video out mystery.
We’ve been doing significant testing lately with video out using various iOS devices for an upcoming project.
