Abstract
A system includes a primary playback system and a secondary playback system. The primary playback system receives primary content including multiple segments of content for playback. The multiple segments of content may include a first segment of content modified by a video analyzer resource to include a supplemental audio signal. During playback of the first segment of content, the primary playback system plays back both an original audio signal associated with the first segment of content and the supplemental audio signal. The supplemental audio signal support synchronization of the secondary playback system with the primary playback system.
Claims35
A method comprising:
- at a video analyzer resource:
- receiving primary content including multiple segments of content encoded for playback on a primary playback system, a first segment of the multiple segments of content including an image portion and an audio portion for playback by the primary playback system;
- and
- modifying the audio portion of the first segment of content to include a supplemental audio signal, subsequent playback of the supplemental audio signal operative to control synchronization of a secondary playback system with respect to the primary playback system.
A system comprising:
- communication management hardware operative to:
- receive primary content including multiple segments of content encoded for playback on a primary playback system, a first segment of the multiple segments of content including an image portion and an audio portion for playback by the primary playback system;
- and
- modify the audio portion of the first segment of content to include a supplemental audio signal, subsequent playback of the supplemental audio signal operative to control synchronization of a secondary playback system with respect to the primary playback system.
A method comprising:
- receiving primary content including multiple segments of content encoded for playback on a primary playback system, a first segment of the multiple segments of content including an image portion and an audio portion for playback by the primary playback system;
- modifying the first segment of content to include a supplemental command signal for playback by the primary playback system, the playback of the supplemental command signal by the primary playback system including audible transmission of the supplemental command signal;
- and
- wherein a secondary playback system is operative to receive the audible transmission of the supplemental command signal and control synchronization of the secondary playback system with respect to the primary playback system based upon execution of the supplemental command signal by the secondary playback system.
A method comprising:
- at a primary playback system:
- receiving primary content including multiple segments of content for playback, the multiple segments of content including a first segment of content modified by an analyzer resource to include a supplemental synchronization control signal;
- and
- during playback of the first segment of content by the primary playback system, audibly playing back both an original audio signal associated with the first segment of content and the supplemental synchronization control signal, the audible playback of the supplemental synchronization control signal by the primary playback system operative to synchronize a secondary playback system with the primary playback system based on execution of the synchronization control signal by the secondary playback system.
