HLS global synchronization and multi-viewer watch parties

Synchronizing is performed of multiple live Hypertext Transfer Protocol (HTTP) Live Streaming (HLS) streams in hypertext markup language (HTML) MediaElements. Time differentials are computed between video encoder date / time tags and current date / time retrieved from a universal time (UTC) time server. A playhead position of an HTML MediaElement is controlled to maintain a calculated time offset value defined as the current date / time minus a predefined time offset. MediaElement source content and the playhead position are dynamically controlled while maintaining video synchronization to the predefined time offset.

Flexible synchronization of time-of-day components

Synchronizing time-of-day (TOD) between TOD components includes issuing an order for a plurality of TOD components, each including a local time, an offset, and an effective time as a sum of the local time and the offset. The effective time of a reference TOD component is the reference time to which target TOD component(s) are to be synchronized. The order directs each of the plurality of TOD components to synchronously, at a point in time, snapshot its local time. This provides a snapshot of the effective time of the reference TOD component, and thus the reference time. The synchronizing synchronizes each target TOD component to the reference time by setting the respective offset as a difference between the target TOD component's snapshot local time and the snapshot of the reference time. Based on the synchronizing, the effective times of the plurality of TOD components match and are the reference time.
