<<A timely PAC-enhancement decision would be compatible with Kenwood's receiver schedule because a PAC upgrade would require no software or hardware changes to existing receiver designs, Kenwood senior VP Bob Law said. If the codec is changed completely however, new receiver hardware will be required, postponing Kenwood's car audio shipments until next year
I could be wrong about this but the possibility that new receiver hardware would be required is what is stopping the NRSC from setting the HD radio standard. Maybe this is kind of like the IEEE 802.11g situation up until recently. Companies shipped 802.11g products before the IEEE actually set the official standard. Some units sold were guaranteed by the manufacturers to either be compliant with the upcoming standard or be upgradeable to it via a firmware patch.
The problem with audio receivers, both home and car, is that firmware upgrades are not as simple as when something is connected to a computer over a wireless link. I would think that manufacturers would wait it out before shipping product as per this comment by the ALpine executive:
|Alpine marketing VP Steve Witt said he needs a codec decision by August in order to ship Alpine car receivers in time for next year's aftermarket selling season, which begins in April
Anyone know anything definitive concerning this?
