multimedia network communication and mobile multimedia

– Understand the basic principal of Java 2 Micro Edition

Outline

• Multimedia Network Communication• Mobile Multimedia• Java 2 Micro Edition (J2ME)

Multimedia Network Communication

• Similar to computer network communication where both deal with data communication

• The different is multimedia data is known as continuous media, which is :– Voluminous– Real-Time and interactive– Sometimes bursty

Quality of Service (QoS)

a collective effect of service performances that determined the degree of satisfaction of that service’s user

• QoS for multimedia data transmission depends on many parameters such as :– Data Rate– Latency (maximum frame/packet delay)– Packet loss or error– Jitter (delay jitter)– Sync Skew

Bina Nusantara

Mobile Multimedia

multimedia information exchange over wireless networks or wireless Internet.

• Increase in usage and development because :– popularity and evolution of mobile computing devices – fast, affordable mobile network

• Common programming language for mobile multimedia application Java 2 Micro Edition (J2ME)

Bina Nusantara

Java 2 Micro Edition (J2ME)

• originally created in order to deal with the constraints associated with building applications for small devices

• a collection of technologies and specifications that can be combined to construct a complete Java runtime environment specifically to fit the requirements of a particular device or market

Bina Nusantara

J2ME elements

Bina Nusantara

provides the most basic set of libraries and virtual machine capabilities for a broad range of devices

a set of APIs that support a narrower range of devices

a set of technology-specific APIs

J2ME Configurations

• Divided into two base configurations :– Connected Limited Device Configuration

(CLDC) , for small mobile devices – Connected Device Profile (CDC) for more

capable mobile devices like smart-phones and set top boxes.

J2ME Profiles

• Personal Profile– suitable for products that require full AWT compatibility

and applet support (high end PDAS and embedded web browsers)

• Foundation Profile – support resource-constrained devices without a

standards-based GUI system (network printers, routers, residential gateways, enterprise-class server applications)

• Mobile Information Device Profile (MIDP)– A profile, when combined with CLDC, provides a standard

Java runtime environment for today's most popular mobile information device for mobile information devices (cellular phones and two-way pagers, and PDAs)Bina Nusantara
