Wireless application protocol (WAP) (Open Mobile Alliance, 2003) is a suite of network protocols that specifies ways of sending data across the airwaves. A wireless device is said to be WAP-compatible if, and only if, it has software that is fully capable of handling all WML 1.1 DTD entities. WML (Wireless Markup Language) (Open Mobile Alliance, 2001) is the XML-based language that is used in conjunction with WAP to format documents. As with all such protocol suites, WAP is organized hierarchically. At the bottom there are low-level protocols that are used for basic operations such as establishing connections, coding alphanumeric characters, and so on. At the top are the high-level protocols such as WML, which passes on page information. For more information on other WAP protocols, please visit http://www.wapforum.org/. WML script writing and applications will be discussed in Chapters VI through IX: • Chapter VI: The current chapter introduces fundamental WML components such as tables and images. • Chapter VII: Advanced WML, especially dynamic WML pages using CGI (Common Gateway Interface), will be introduced. • Chapter VIII: WMLScript, a lightweight JavaScript language used in conjunction with WML, is explained. • Chapter IX: The construction of a database-driven mobile web site using WML is explained step-by-step.

In the digital world, several ways to organize and describe digital rights management (DRM) have been developed to enforce fairness and transparency in business trades. Metadata is beginning to serve this purpose as it attempts to address property rights, licensing, privacy, and confidentiality issues in a manner that ideally renders information or content easily accessible over a variety of platforms (Koenen, 2001). With the rise of security breaches and computer crimes such as identity theft, DRM is increasingly an issue for creators, content owners, purveyors, and consumers of all sorts of digital materials. This article defines what DRM is and explains how it is implemented into description and assessment in practical metadata schemes. DRM components are discussed, in particular those related to identification and rights expression. The two commonly used standards of describing DRM are discussed with Open Mobile Alliance and MPEG-21 (Rosenblatt, 2005). Issues and problems of metadata in DRM are also discussed for future implications.

In this article, the Multimedia Broadcast and Multicast Service (MBMS) as standardized in 3GPP is presented. With MBMS, multicast and broadcast capabilities are introduced into cellular networks. After an introduction into MBMS technology, MBMS radio bearer realizations are presented. Different MBMS bearer services like broadcast mode, enhanced broadcast mode and multicast mode are discussed. Streaming and download services over MBMS are presented and supported media codecs are listed. Service layer components as defined in Open Mobile Alliance (OMA) are introduced. For a Mobile TV use case capacity improvements achieved by MBMS are shown. Finally, evolution of MBMS as part of 3GPP standardization is presented.
