CGI - (the Common Gateway Interface) is a standard way for a Web server to pass a Web user's request to an application program and to receive data back to forward to the user. The common gateway interface provides a consistent way for data to be passed from the user's request to the application program and back to the user. This means that the person who writes the application program can makes sure it gets used no matter which operating system the server uses (PC, Macintosh, UNIX, OS/390, or others). It's simply a basic way for information to be passed from the Web server about your request to the application program and back again.

MPEG standards - The MPEG standards are an evolving set of standards for video and audio compression and for multimedia delivery developed by the Moving Picture Experts Group (MPEG).
MPEG-1 was designed for coding progressive video at a transmission rate of about 1.5 million bits per second. It was designed specifically for Video-CD and CD-i media. MPEG-1 audio layer-3 (MP3) has also evolved from early MPEG work.
MPEG-2 was designed for coding interlaced images at transmission rates above 4 million bits per second. MPEG-2 is used for digital TV broadcast and DVD. An MPEG-2 player can handle MPEG-1 data as well.
MPEG-1 and -2 define techniques for compressing digital video by factors varying from 25:1 to 50:1. The compression is achieved using five different compression techniques.
MPEG-3 A proposed MPEG-3 standard, intended for High Definition TV (HDTV), was merged with the MPEG-2 standard when it became apparent that the MPEG-2 standard met the HDTV requirements.
MPEG-4 is a much more ambitious standard and addresses speech and video synthesis, fractal geometry, computer visualization, and an artificial intelligence (AI) approach to reconstructing images. MPEG-4 addresses a standard way for authors to create and define the media objects in a multimedia presentation, how these can be synchronized and related to each other in transmission, and how users are to be able to interact with the media objects.
MPEG-21 provides a larger, architectural framework for the creation and delivery of multimedia.

SMIL - (Synchronized Multimedia Integration Language), is a language that allows Web site creators to be able to easily define and synchronize multimedia elements (video, sound, still images) for Web presentation and interaction. On today's Web, although you can send moving and still images and sound to a Web user, each element is separate from the others and can't be coordinated with other elements without elaborate programming. SMIL (pronounced "smile") lets site creators send multiple movies, still images, and sound separately but coordinate their timing. Each media object is accessed with a unique Uniform Resource Locator (URL) which means that presentations can be made of objects arriving from more than one place and that objects can easily be reused in multiple presentations.
SMIL also lets the "producer" store a media object in multiple versions, each with a different bandwidth so that a lower-bandwidth version of a Web page can be sent to users who need it. SMIL also accommodates multiple language versions of soundtracks.

VDSL - (Very-high speed Digital Subscriber Line) will eventually emerge as a primary "last-mile" broadband solution for both the home and business. The value proposition for VDSL in both marketplaces is very attractive. VDSL enables Telcos to offer broadband services that provide a quantum leap in terms of access speed and applications available to the end user. VDSL provides Telcos the technology to compete in the residential market for bundled voice, data and video services using copper infrastructure without having to install fiber-to-the-home. Likewise, VDSL will provide a very low cost data transfer technology enabling high-speed data networking, high quality video conferencing and multiple voice lines for businesses over the existing copper infrastructure. Although the capabilities of VDSL are revolutionary, the industry has to overcome distance limitations and standards issues before the technology will be viable as a mass-market solution.
VDSL is one of the most promising technologies to emerge in the current telecommunications market. Like other xDSL technologies (ADSL, SDSL and G.lite), VDSL utilizes a single twisted copper pair to provide high speed access. While other xDSL services are capable of up to 8 Mbps download speed, VDSL facilitates transfer rates of up to 52 Mbps, which is 1,000 times the capacity of today's dial-up lines. VDSL soon will be cost competitive with other xDSL technologies.

SVG - (Scalable Vector Graphics) is the description of an image as an application of the Extensible Markup Language (XML). Any program such as a Web browser that recognizes XML can display the image using the information provided in the SVG format. vector graphics is the expression of an image using mathematical statements rather than bit-pattern description. Scalable emphasizes that vector graphic images can easily be made scalable (whereas an image specified in raster graphics is a fixed-size bitmap). Thus, the SVG format enables the viewing of an image on a computer display of any size and resolution, whether a tiny LCD screen in a cell phone or a large CRT display in a workstation. In addition to ease of size reduction and enlargement, SVG allows text within images to be recognized as such, so that the text can be located by a search engine and easily translated into other languages.
Vector graphics images also have the potential advantage over the standard Web image formats, the GIF and the JPEG, of size. Compared with a bitmap image, an SVG image may be much smaller and arrive more quickly.

WSDL - (the Web Services Description Language) is an XML-based language used to describe the services a business offers and to provide a way for individuals and other businesses to access those services electronically. WSDL is the cornerstone of the Universal Description, Discovery, and Integration (UDDI) initiative spearheaded by Microsoft, IBM, and Ariba. UDDI is an XML-based registry for businesses worldwide, which enables businesses to list themselves and their services on the Internet. WSDL is the language used to do this.
WSDL is derived from Microsoft's Simple Object Access Protocol (SOAP) and IBM's Network Accessible Service Specification Language (NASSL). WSDL replaces both NASSL and SOAP as the means of expressing business services in the UDDI registry.
