STUDIES PERFORMED

• Design goals of SMIL2.0
• Extended functionalities
• ? more interaction extended layout timing
  semantics
• new animations ...
• Declarative format rather than procedural format
• Fully XML compliant
• Module based structure
• It is media composition

6
STUDIES PERFORMED

• Functional Grouping of SMIL2.0
• It represents collection of SMIL2.0 modules which
  
• are used to define SMIL2.0 profile.

STUDIES PERFORMED

• Animationused to give time varying values to
• elements and attributes.
• Content controlused to conditionally include
  media
• items in a presentation based on user-defined
  test
• attributes and various systems(bandwidth,screen
  size).

ltswitchgt lt video src...
systemBitrate115200/gt ltseq
systemBitrate57344gt ltimg
srcimg1.png dur5s/gt ...
ltimg srcimg12.png dur9s/gt
lt/seqgt lttext srcdesc.html
dur30s/gt lt/switchgt

• If bit rate112KB
• ? shows video
• If bit rategt56KB and bit ratelt112KB
• ? shows sequence of images
• If no other element is selected in a switch
• ? shows a text

8
STUDIES PERFORMED

• Layout used to manage a presentations rendering
  
• space.
• Ex sub region positioning and alignment
  mechanisms
• LinkingIt is used to define and manage both SMIL
  
• temporal and HTML-like nontemporal links.
• Ex we can define an anchor to point at a part or
  all of an object,
• for part or all of its rendering time, and link
  to internal or external
• media objects when activated.

9
STUDIES PERFORMED

• Metainformation used for encoding
• metainformation on an entire presentation.
• Ex adding author, title, date and other such
  information to our
• presentation.
• Structure used to define basic structure of SMIL
  
• documents. Therefore it defines SMIL content and
• how its element is encoded.

10
STUDIES PERFORMED

• Media objects used to include media elements in
  a
• presentation.
• ltimggt,ltvideogt,ltaudiogt,lttextgt,ltanimationgt,lttextst
  reamgt
• (All media in a SMIL presentation are brought
  in using the src attribute.)
• Ex ltimg src"a.jpg" dur"6s begin"0s"/gt
• ltaudio src"a.mp3" dur"6s begin"0s"/gt
• ltvideo src"a.mpg" dur"6s begin"0s"/gt
• lttext src"a.txt" dur"6s begin"0s"/gt

11
STUDIES PERFORMED

• Timing and Synchronization used to define
• timing models.Basic timing containers

• Sequential
• Time Container

• Exclusive
• Time Container

• Parallel Time
• Container

• ltseqgt
• ltimg src"a" begin"0s" dur"6s"/gt
• ltimg src"b" begin"0s" dur"4s"/gt
• ltimg src"c" begin"2s" dur"5s"/gt
• lt/seqgt

ltpargt ltimg src"a" begin"0s" dur"6s"
/gt ltimg src"b" begin"0s" dur"4s" /gt ltimg
src"c" begin"2s" dur"5s" /gt lt/pargt
ltexclgt ltimg src"a" dur"6s"
begin"x.activateEvent" /gt ltimg src"b" dur"4s"
begin"y.activateEvent" /gt ltimg src"c"
dur"5s" begin"z.activateEvent" /gt lt/exclgt
12
STUDIES PERFORMED

• These timing containers can be nested for example

ltpar endsyncselectgt ltimg srcimg1.jpg
idbtn_a dur10s /gt ltimg
srcimg2.jpg idbtn_b dur5s /gt
ltexcl idselectgt lttext
srctodays.txt. beginbtn_a.activeEvent
dur25s/gt ltvideo
srctodays_video.mpg beginbtn_b.activeEvent
/gt lt/exclgt ltaudio
srctodays_tune.mp3 repeatindefinite/gt lt/pargt

13
STUDIES PERFORMED

• Attributes that are used for timing begin, end
  and dur
• Types of duration

(a) Inherent Duration (b) Simple
Duration (c) Active Duration (d) Rendered
Duration
ltaudio src"x.mp3" /gt
(a) (b) (c) (d)
ltaudio src"x.mp3" dur 6s" /gt
ltaudio src"x.mp3" dur 6s" repeatCount 2s"/gt

ltaudio src"x.mp3" dur 6s" repeatCount 2s"
fill freeze" /gt
14
STUDIES PERFORMED

• Time manipulation defines how we can
• manipulate time within a presentation.
• Ex Some profiles let time elapse faster or
  slower than normal
• play time.
• Transitions It is a collection of modules that
  add
• visual transitions to a presentation.
• Ex these modules define how objects can appear
  using fades,
• wipes.

15
STUDIES PERFORMED

• SMIL 2.0 Implementation Profiles
• SMIL language implements nearly all SMIL 2.0s
  modules
• ?RealNetworks and Oratrix
• SMIL basiccollection of modules that support
  SMIL on minimal devices.
• ? used as the basis for the wireless
  multimedia specification by the 3GPP consortium
• SMIL animation is not a technically a language
  profile but rather module integration.
• XHTMLSMILdefines a collection of modules that
  lets us integrate SMIL timing and presentation
  semantics in other, typically nontemporal XML
  documents.
• ?Microsofts Internet Explorer 5.5 and 6.0

18
STUDIES PERFORMED

• SMIL 2.0 and MPEG-4
• ?MPEG-4 is a final-form presentation description
  and contains
• extensive content and control information.
• SMIL 2.0 document provides a specification of the
  high-level
• and detailed synchronization, layout and content
  control.
• ?Both SMIL and MPEG-4 use a profile-based
  architecture
• ?MPEG-4s profile architecture is significantly
  more complex
• than SMILs.

19
CONCLUSION

• SMIL2.0s useful features
• ?Display multiple types of files such as text,
  video, audio,
• ?Define layout and duration of elements
• ? Used in applications such as electronic
  commerce and distance education
• ? is a tool to make existing Web and its
  various interfaces more animated, informative,
  and accessible.
• ? helps to build large-scale interactive
  multimedia for playback
• SMIL2.0s useful features improve fastly
• ?The SYMM Working Group completed SMIL1.0,
  SMIL 2.0 and is currently working on a new
  version (SMIL 3.0).
