1 Multimedia Network Communications Subject:T0934 / Multimedia Programming Foundation Session:13 Tahun:2009 Versi:1/0

2 Bina Nusantara Learning Outcomes In the end of this session, students must be able to: –Understand the overview of multimedia network communication and mobile multimedia –Understand the basic principal of Java 2 Micro Edition

3 Outline Multimedia Network Communication Mobile Multimedia Java 2 Micro Edition (J2ME) Bina Nusantara

4 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 Bina Nusantara

5 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

6 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

7 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

8 J2ME elements Bina Nusantara Java ME elements configurationprofile optional package 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

9 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. Bina Nusantara CLDC 128K to 512K total memory available Limited power, often battery operation. Connectivity to some type of network, often with a wireless, intermittent connection and limited bandwidth CDC At least 512K ROM and 256K RAM a device that can support a complete JVM implementation.

10 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
