More Information
Summary:A sink device (160) in a Wireless Display (WD) system (100) may send performance information feedback to a source device (120) to adjust media data processing at the source device (120). The performance information feedback may include performance indicators of the WD system that are capable of being measured or calculated at the sink device (160) based on received media data or request to adjust the transmission of media data. For example the performance information feedback may include one or more of round trip delay delay jitter packet loss ratio error distribution and received signal strength indication (RSSI). The feedback channel may be piggybacked on a reverse channel architecture referred to as the User Input Back Channel (UIBC) implemented between the source device (120) and the sink device (160).
