Apparatus, method, and computer readable medium for providing a presentation on a network having a plurality of synchronized

A non-transitory computer readable medium comprising instructions configured to cause a processor to perform a process, the process comprising:

• receiving a timing parameter indicating a time at which to display a presentation portion comprising first stream content and second stream content;
• synchronizing display of the first stream content with the second stream content to a client node using a stream delay parameter;
• wherein the first stream content and the second stream content have a same stream delay;
• wherein the first stream content and the second stream content are synchronously rendered at the client node at a time derived from the time indicated by the timing parameter and the stream delay parameter;
• and
• correlating a start point of an audio sample corresponding to audio pattern data at the client node with the timing parameter;
• wherein the timing parameter becomes a stream time for the start point on the client node;
• wherein the correlating is performed by pattern the audio pattern data against a normalized audio data window in the client node.

An apparatus, comprising:

• a processor configured to:
• receive a timing parameter indicating a time at which to display a presentation portion comprising a first stream content and a second stream content;
• synchronize display of a real-time content and the stream content to a client node using a stream delay parameter;
• wherein the first stream content and the second stream content have a same stream delay;
• wherein the first stream content and the second stream content are synchronously rendered at the client node at a time derived from the time indicated by the timing parameter and the stream delay parameter;
• and
• correlate a start point of an audio sample corresponding to audio pattern data at the client node with the timing parameter;
• wherein the timing parameter becomes a stream time for the start point on the client node;
• wherein the correlating is performed by pattern mat rig the audio pattern data against a normalized audio data window in the client node.
