| Abstract | A Data Distribution System And A Protocol For Interactive Information Services Over A Network And In Particular For Video-On-Demand Applications. A Shared Buffer And A Split-And-Merge Protocol Are Implemented To Allow Multiple Users To Share The Same Video Stream Multicasted Over A Network With True Vod Services Including The Ability To Access Any Available Video At Any Time, And To Perform Any Vcr-Like Functions And Random Access. Video Requests For A Video Program Are Served In Batches. A User Interaction Is First Handled By Splitting Off The Interactive User From A Shared Video Stream In A Batch, And By Subsequently Assigning The User A New Dedicated Video Stream. The Interactive User Is Subsequently Merged Back To One Of The Batching Video Streams Shared By Multiple Users Upon Resuming Normal Play Mode. |
