Synchronization is The Co-ordination of The Events To Operate A System in Unison .
Systems operating with all their parts in synchrony are said to be synchronous or in sync.

MULTIMEDIA SYSTEM :-
A system or application that
supports the integrated processing
of several media types .

Two type of media data :-
1.Continuous : Time-Dependent
Ex :- Real-Service (Live Video)
2.Discrete : Time-Independent
Ex :- Text or Graphic
Three Levels Of MM Synchronization :-
1. Intra-Media Synchronization
2. Inter-Media Synchronization
3. Inter-Party Synchronization

1. Intra-Object Synchronization :-
Time Relation Between Various Presentation Units of One Time-Dependent
Media Object
Ex : Time relation between the single frames of a video sequence. For a video with
a rate of 25 frames per second each of the frames has to be displayed for 40 ms .
Frames of a video sequence that shows a jumping ball

2. Inter-Object Synchronization :-
The Synchronization Between Media Objects .
Ex : Time Relations of A Multimedia Synchronization That Starts With
Audio/Video Sequence , Followed By Several Pictures And An Animation That is
Commented By An Audio Sequence .

3. Inter-Party Synchronization :-
Also Known As Event Synchronization
Maintains The Inter-Media and/or Intra-Media
Synchronization Among Different Participants
At Distributed Locations .
Ex. Remote Learning
Video Conferencing

Logical Data Unit (LDU) Hierarchy :-
LDU is the unit of a media stream. Different streams have different LDU size.
Example of Video/Audio/User-Defined LDU :-

Synchronized Multimedia Integration Language (SMIL) :-
SMIL (Pronounced "smile") Enables Simple Authoring
Of Interactive Audiovisual Presentations .
SMIL is Typically Used for “Rich Media"/ Multimedia
Presentations Which Integrate Streaming Audio And
Video With Images , Text Or Any Other Media Type .
SMIL is An Easy-To-Learn HTML- Like Language .
SMIL Presentations Are Written Using A Simple Text-Editor .
