ACMI is not available for purchases made online at the following special stores: Apple Employee Purchase Plan participating corporate Employee Purchase Programs Apple at Work for small businesses Government, and Veterans and Military Purchase Programs, or on refurbished devices. See the Apple Card Customer Agreement for more information. Taxes and shipping are not included in ACMI and are subject to your card’s variable APR. If you choose the pay-in-full or one-time-payment option for an ACMI-eligible purchase instead of choosing ACMI as the payment option at checkout, that purchase will be subject to the variable APR assigned to your Apple Card. Variable APRs for Apple Card other than ACMI range from 11.24% to 22.24% based on creditworthiness. See for more information about eligible products. When this will happen I can’t say for anonymous reasons, but these concerns haven’t gone unnoticed.◊ Apple Card Monthly Installments (ACMI) is a 0% APR payment option available to select at checkout for certain Apple products purchased at Apple Store locations,, the Apple Store app, or by calling 1-800-MY-APPLE, and is subject to credit approval and credit limit. Given the dynamic nature of the system (and the fact that the firmware is stored in RAM rather then ROM), updates **will** be made available as a part of future iOS updates. For the time being, the quality was deemed to be suitably acceptable. Since the iOS device doesn’t care about the hardware hanging off the other end, you don’t need a new iPad or iPhone when a new A/V connector hits the market.Ĭertain people are aware that the quality could be better and others are working on it. This system essentially allows us to output to any device on the planet, irregardless of the endpoint bus (HDMI, DisplayPort, and any future inventions) by simply producing the relevant adapter that plugs into the Lightning port. The encoded data is transferred as packetized data across the Lightning bus, where it is decoded by the ARM SoC and pushed out over HDMI. Airplay itself (the network protocol) is NOT involved in this process. Airplay uses a bunch of hardware h264 encoding technology that we’ve already got access to, so what happens here is that we use the same hardware to encode an output stream on the fly and fire it down the Lightning cable straight into the ARM SoC the guys at Panic discovered.

Again, it’s just a high speed serial interface. Lightning doesn’t have anything to do with HDMI at all. It’s vastly the same thing with the HDMI adapter. The GPIB adapter contains all the relevant Lightning -> GPIB circuitry. If you wanted to produce a Lightning adapter that offered something like a GPIB port (don’t laugh, I know some guys doing exactly this) on the other end, then the only support you need to implement on the iDevice is in software- not hardware.
#APPLE LIGHTNING DIGITAL AV ADAPTER FREE#
We did this to specifically shift the complexity of the “adapter” bit into the adapter itself, leaving the host hardware free of any concerns in regards to what was hanging off the other end of the Lightning cable. Contrary to the opinions presented in this thread, we didn’t do this to screw the customer. There is no clever wire multiplexing involved. The reason why this adapter exists is because Lightning is simply not capable of streaming a “raw” HDMI signal across the cable. That's why he mentions offloading work to the adapter.
Essentially a very low powered iOS device.
Oh, and just in case anyone wasn't aware, the Lightning Adapter has both a processor and memory. I'm just dropping it in to shed a little more light on the Lightning AV system and, if true, the potential for future improvements to the quality it outputs. He's responding to an article from the guys at Panic who found that in some cases the adapter was only outputting a 900p image. Here's a quote from an "anonymous Apple engineer" regarding the Lightning Digital AV Adapter.
