Last Saturday we talked about the microcomputer that Apple put inside the Lightning Adapter for Digital AV and the possible reasons for it to do so. The most adequate theory at the time was that the new Lightning connector does not support video output (which is in fact true) and that the 256MB ARM processor inside the adapter would serve to send the video signal from the iGadget to the TV via AirPlay or something like that.
Today, however, a very technical, explanatory and supposedly written post by an Apple engineer appeared on the Slashdot, stating that * no * exists AirPlay or any other streaming in the move. Instead, SoC (system-on-a-chip or, in Portuguese, system-on-a-chip) the adapter decodes the H.264 video received from the iGadget and sends it to the television via HDMI.
On the issue of Full HD (1080p) resolution not being supported by the adapter, the anonymous who posted about it said that, as the adapter's firmware is stored in RAM (random access memory, or random access memory), Apple can update it at any time most probably still has not done so as it has not found a safe way to guarantee the transmission quality in 1080p.
He also explains that the Apple system (microcomputer inside the adapter) allows the delivery of the video regardless of the output connector (HDMI, DisplayPort, Thunderbolt or any other that appears in the future), just making an adapter with the connector in question. In other words, the "heart" of the adapter can always be the same, just "change" the tip of the connector (HDMI, DisplayPort, Thunderbolt, etc.). In doing so, we will not need a new iPad, iPhone or iPod touch for it to be compatible with a future adapter.
If Apple can even implement Full HD on this adapter, it was undoubtedly a good move for her and not ?a little way?, as we thought.
