Abstract
This disclosure describes embodiments of systems and methods that use protocols and techniques that can stream audio from a video device to a separate device while reducing or eliminate audio/video synchronization errors. In some embodiments, these systems and methods use Voice over IP (VoIP) technology to stream audio to mobile devices with low latency, resulting in little or no user-perceivable delay between the audio stream and corresponding video presentation. As a result, users can enjoy both the audio and video of any video display in an establishment. In addition, the systems and methods described herein may be implemented in the home or other locations to allow viewers who may be hard of hearing to listen to audio clearly via headphones.
