Techniques for synchronizing timing of wireless streaming transmissions to multiple sink devices

Abstract

Methods, systems, apparatuses, and devices are described for synchronizing timing of wireless streaming transmissions to multiple sink devices. A source device may identify timing information associated with a common timing source, e.g., a media timing source at multimedia layer or a Wi-Fi timing source, and send the timing information to the sink devices. The sink devices may receive the timing information and determine a composite timing delay, e.g., a wireless transmission link delay, an internal interface link delay, or combinations thereof. The source device may stream the content to the sink devices which may use a locally adjusted timing signal to synchronize the presentation of the content.
