How will digital transmissions affect internet webstreaming? What additional equipment will be required for smooth transitioning and quality transmission?
These are really two different systems and one is not affected or limited by the other. At this time it is not possible to use the HD Radio codec for streaming audio therefore two different codecs would be required. The most important thing to do, as you move forward with equipment purchases, is to move toward transporting and working with linear digital audio within the studio plant and within any STL transport system. The idea is to avoid subjecting the audio to any data bit reduction (digital compression) schemes as the IBOC codec and any streaming audio codec will be doing that and you do not want to cascade compression algorithms as this will quickly degrade audio quality.
