It provides a framework for
embedded multimedia
facilities in java enabled
mobile devices.
 MMAPI
is a specification of the Java
Technology for Wireless Industry(JTWI)
specification (JSR-135) provided by JCP(Java
Community Process).
 MMAPI
provides a high level interface to
provide specific HTTP, Audio & Video.
 MMAPI
CDC.
are compatible with both CLDC &
 MMAPI
provides support for various
multimedia capabilities , such as tone
generation, audio and video playback.
 MMAPI requires limited resources, very less
memory and processing capabilities.
 Its is not protocol or format specific, it
supports most of the multimedia capable
audio & video formats such as MP3 & WAV.
 It provides extensible & flexible framework,
so new features can be added to it, without
making any modification to old version API.
 It
consist of DataSource, Player, Manager and
Control.
Provides data
DataSource
provides
Control
Player
Control
Creates
Manager

Player: Controls and reads the data provided by the
DataSource. Its life Cycle includes five states, these
are UNREALIZED, REALIZED, PREFETCHED, STARTED &
CLOSED. This object is stored in heap memory.

Life Cycle of a player started in unrealized state and
it does not have enough information to acquire.

The realized state helps the player to acquire media
sources and after that it changes the state from
unrealized to realized.

In prefetched state it acquire resources and fills
buffer data. After that it enters into Started State.
Then the stop() is use to stop the player and in close
state it releases the acquired resources.
 DataSource:
Consist of process of protocol
handling and hides the detail of processing
data. it can be created from either an input
stream instance or a URL.
 Controls:
Provides control over the
functionality of player.
 Manager:
It represents static factory class.
The createPlayer() method of the Manage
class creates an instance of player
 It
provides following three packages:
 The javax.microedition.media Package
 The javax.microedition.media.control
package
 The javax.microedition.media.protocol
package
All the above packages are consist of useful
classes and interfaces, such as player
interface, ToneControl interface, DataSource
class etc.
