Multimedia Streaming Technology n 4G Mobile
Communication Systems
The popularity of laptops, mobile phones and Personal Digital Assistants and and the evolution of fast mobile networks, it is today possible to provide high qualitymobile applications and services to the end-users. The 4G technology combines standardized streaming
with a range of unique services to provide high-quality multimedia content . By providing data-transmission rates up to 20 Mbps, the 4G communication systems can provide provide high quality
streamed content to the end users.
MOBILE STREAMING CHALLENGES
mobile streaming services face the following challenges.
Heterogeneity
The display sizes and capabilities of mobile phones varying very much, and also different radio-access networks making multiple maximum-access page link speeds available. This can be mitigated by
capability exchange mechanisms that can enable the terminal and media server to negotiate mobile terminal and mobile network capabilities and user preferences.
Content Protection
This involves controlling what users can do
with conten. In the simplest form , content protection can be to is simply disallow the storage of received contentdigital rights . It also involves the management (DRM) concept, which uses
encryption and conditional access based on
usage rules to protect multimedia data.
. To prevent illegal copying ofmultimedia content like music and movies, the content providers are reluctant to deliver premium content
over digital networks without DRM mechanisms.
Streaming standardisation
The Internet Streaming Media Alliance (ISMA) and the Wireless Multimedia Forum (WMF) have emphasised the need for standardisation of the streaming services. The multimedia
protocol stacks and codecs video and audio
compression/decompression software must be standard to all the end user equipments.

INTRODUCTION
Many portal sites offer streaming audio and video services for accessing news and entertainment content on the Internet from a PC. The term multimedia streaming means that there are more than one media type involved in the communication, e.g. text and graphics, voice, animations, video and audio. We defines multimedia to denote the property of handling a variety of representation media in an integrated manner. This means that the various sources of media types are integrated into a single system framework. Currently, three incompatible proprietary solutions offered by Real Networks, Microsoft, and Apple dominate the Internet streaming software market. In the near future, third-generation mobile communication systems will extend the scope of today_s Internet streaming solutions by introducing standardized streaming services, targeting the mobile user_s specific needs. By offering higher data-transmission rates up to 20 Mbps more than 3G for wide-area coverage and local-area coverage, 4G systems will be able to provide high quality streamed content to the rapidly growing mobile market. In addition to higher data rates, these systems also will offer value-added applications supported by an underlying network that combines streaming services with a range of unique mobile specific services such as Multimedia content, geographical positioning, user profiling, and mobile payment. Mobile cinema ticketing is one example of such a service. First, the mobile network or a terminal integrated positioning system such as GPS would determine the user_s geographical location. Then, the service would access a cinema database to generate a list of nearby movie theatres and a user profile database to determine what kind of movies the user likes best. Based on the geographical location information and user-defined preferences, the service would offer the user a selection of available movies and show times. The user would then have the option of using the mobile device to view corresponding movie trailers through a streaming service. Upon choosing a film, the user could purchase a ticket through payment software on the mobile device. This and other mobile application scenarios present numerous challenges, such as how to provide spectrum efficient streaming services over varied radio-access networks to different types of end-user terminals. Our standard-based Interactive Media platform addresses these challenges by using an architecture that fits seamlessly into 4G mobile communication systems. An integral part of this architecture is a streaming proxy, which acts on both the service and transport levels. It is flexible enough to deal with different operator requirements and that it can provide high-quality streaming services in a mobile application environment
.2. 4G MOBILE COMMUNICATION SYSTEMS
International Mobile Telecommu-nications - 2000 (IMT-2000) and the Universal Mobile Telecommunications System (UMTS) will be among the first 3G mobile communication systems to offer wireless wideband multimedia services using the Internet protocol. Two important technological changes will facilitate this advancement. The first change is a shift from last-generation radio-access technologies such as the global system for mobile (GSM) communication, CDMAOne (an IS-95 code division multiple access standard), and personal digital cellular (PDC) toward more sophisticated systems with higher data-transfer rates such as the enhanced data. fourth-generation mobile communication systems will combine standardized streaming with a range of unique services to provide high-quality content that meets the specific needs of the rapidly growing mobile market. GSM environment (EDGE), wideband CDMA (WCDMA), and cdma2000. As Figure 1 illustrates, the second important technology shift is from a vertically integrated to a horizontally layered service environment. A horizontally layered 4G service network seamlessly integrates Internet protocol transport into a mobile service environment with a variety of access networks, opening up many new opportunities for IP-based mobile applications. For example, mobile terminals will be able to access existing Internet content through protocols and markup languages such as WAP and WML that are optimized for wireless application scenarios. 4G mobile communications will have transmission rates up to 20 Mbps_ higher than of 3G. The technology is expected to be available by the year 2010. 4G is being developed with the following objectives: 1. Speeds up to 50 times higher than of 3G. However, the actual available bandwidth of 4G is expected to be about 10 Mbps. 2. Three-dimensional virtual reality_imagine personal video avatars and realistic holograms, and the ability to feel as if you are present at an event even if you are not. People, places, and products will be able to interact as the cyber and real worlds merge. 3. Increased interaction between corroborating technologies; the smart card in your phone will automatically pay for or will tell your car to warm up in the morning as your phone has noted you leaving the house. We can use new technology such as CDMA wireless access technology, advanced antenna systems, next-generation mobile Internet, quality of service, power amplifier technology, and wireless access networks in 4G mobile communication system.4G applications include high-performance streaming of multimedia content based on agent technology and scaleable media coding methods.4G will solve problems like limited bandwidth in 3G when people are moving and uncertainty about the availability of bandwidth for streaming to all users at all times. The 4G networks will also provide access to support services such as authentication, security, and billing mechanisms as well as mobile-specific services
