Lightning to Digital AV adapter could be pushing lower res H.264 because it's not yet capable of streaming raw HDMI
Earlier today we linked to a post by Cabel Sasser on the Panic Blog about Apple's Lightning Digital AV connector, which is basically their HDMI adapter. Sasser had discovered that the adapter provided a less-than-1080p signal, broke it open, and found a tiny computer contained inside. Lots of speculation followed as to why that was, and what might be going on. A comment left on the Panic Blog by "Anonymous Coward", however, implies internal Apple knowledge of the matter, and purports to have the answer. In part, the comment says:
If the comment is legitimate -- and there's no way to know at this point if it is or not -- Apple is basically hanging all the electronics outside the device, rather than glutting Lightning up with signals that may fall into disuse over the time. There are trade-offs, to be sure, but given how the old 30-pin Dock connector abandoned FireWire over time, added HDMI, and jumbled in everything from line to serial, if accurate, this could also be a better, more future-proof solution.
And, since the on-device side is software-centric, an update could improve the HDMI out to true 1080p. Fingers crossed.
If anyone has any specific knowledge of how this kind of stuff works, give the full comment a read via the link below and then please weigh in a let me know how likely (or unlikely) it all sounds.
