Abstract
A portable media device (PMD) can produce an isochronous audio/video experience when the PMD provides a digital audio signal to the accessory while displaying analog video on an accessory-independent display. The accessory can communicate audio latency information to the PMD. The PMD can delay a video portion of a presentation, relative to providing the digital audio signal to the accessory, based on the audio latency information communicated by the accessory. As a result, the user may perceive an isochronous presentation of the audio and video portions of the presentation.
