Abstract: Methods and apparatus are described for providing content playback options to content playback systems based on the capabilities of the systems. These techniques determine whether the content options should be provided based on the capabilities of a source device in a combined playback system. The version of the High-bandwidth Digital Content Protection (HDCP) protocol used to initialize the connection between the source and sink devices is determined. Based on the version of the HDCP protocol used, an override message may be sent to the content service, in response to which the media player on the source device is directed to an content service endpoint corresponding to particular set of playback options.
