WAP TV
WapTV now Miniweb was the name given to the company which originated the WTVML (Worldwide TV Mark-up Language) as a content format for the delivery of Interactive TV applications using Internet Servers. The system is an Interactive television technology platform comprising a mobile browser, a markup language, and a significant collection of associated software tools and services. The mobile browser and mark-up language are both based upon the Open Mobile Alliance WML 1.3 specification. The WTVML mobile browser is currently available only as an OpenTV application, although an MHP version of the WapTV browser has been built for demonstration and proof of concept. An emulator exists, based on Craftwork's, STBe OpenTV middleware emulation. The WTVML markup language is a heavily extended superset of the WAP Forum WML 1.3 specification. WML content originally designed for wireless delivery to mobile phone handsets will work without modification on the WTVML platform, with the excepti ...

Content Format
A content format is an encoded format for converting a specific type of data to displayable information. Content formats are used in recording and transmission to prepare data for observation or interpretation. This includes both analog and digitized content. Content formats may be recorded and read by either natural or manufactured tools and mechanisms. In addition to converting data to information, a content format may include the encryption and/or scrambling of that information. Multiple content formats may be contained within a single section of a storage medium (e.g. track, disk sector, computer file, document, page, column) or transmitted via a single channel (e.g. wire, carrier wave) of a transmission medium. With multimedia, multiple tracks containing multiple content formats are presented simultaneously. Content formats may either be recorded in secondary signal processing methods such as a software container format (e.g. digital audio, digital video) or recorded i ...

TV Sites
A TV site is a website designed for viewing on a television set. Unlike mobile and PC access, the use of internet sites through the TV has been small, mostly due to the poor user experience of many "web on TV" deployments, and the "walled garden" or closed platform business models adopted by many TV network operators. With the advent of IPTV and Broadband enabled TV Devices web site owners have realized, that like Mobile, TV needs to be considered as a different media, and that Mobile, TV and PC based internet access all present different user interface design challenges in order to make the services usable and acceptable to consumers on the device they are using. TV Sites can be developed and deployed using a number of different technologies including Adobe Flash, WTVML, Java and HTML, although the same design principles apply whatever the development technology. Typically TV Sites are differentiated from other web sites by having a "wtv." rather than a "www." subdomain. Inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Browsers
A web browser is application software for accessing websites. When a User (computing), user requests a web page from a particular website, the browser retrieves its Computer file, files from a web server and then displays the page on the user's screen. Browsers are used on a range of devices, including desktop computer, desktops, laptops, tablet computer, tablets, and smartphones. In 2020, an estimated 4.9 billion people used a browser. The Usage share of web browsers, most used browser is Google Chrome, with a 65% global market share on all devices, followed by Safari (web browser), Safari with 18%. A web browser is not the same thing as a search engine, though the two are often confused. A search engine is a website that provides hyperlink, links to other websites. However, to connect to a website's server and display its web pages, a user must have a web browser installed. In some technical contexts, browsers are referred to as user agents.

Web Server
A web server is computer software and underlying hardware that accepts requests via HTTP (the network protocol created to distribute web content) or its secure variant HTTPS. A user agent, commonly a web browser or web crawler, initiates communication by making a request for a web page or other resource using HTTP, and the server responds with the content of that resource or an error message. A web server can also accept and store resources sent from the user agent if configured to do so. The hardware used to run a web server can vary according to the volume of requests that it needs to handle. At the low end of the range are embedded systems, such as a router that runs a small web server as its configuration interface. A high-traffic Internet website might handle requests with hundreds of servers that run on racks of high-speed computers. A resource sent from a web server can be a preexisting file (static content) available to the web server, or it can be generated ...

Extensible Markup Language
Extensible Markup Language (XML) is a markup language and file format for storing, transmitting, and reconstructing arbitrary data. It defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The World Wide Web Consortium's XML 1.0 Specification of 1998 and several other related specifications—all of them free open standards—define XML. The design goals of XML emphasize simplicity, generality, and usability across the Internet. It is a textual data format with strong support via Unicode for different human languages. Although the design of XML focuses on documents, the language is widely used for the representation of arbitrary data structures such as those used in web services. Several schema systems exist to aid in the definition of XML-based languages, while programmers have developed many application programming interfaces (APIs) to aid the processing of XML data. Overview The main purpose of XML is serialization, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcast Domain
A broadcast domain is a logical division of a computer network, in which all nodes can reach each other by broadcast at the data link layer. A broadcast domain can be within the same LAN segment or it can be bridged to other LAN segments. In terms of current popular technologies, any computer connected to the same Ethernet repeater or switch is a member of the same broadcast domain. Further, any computer connected to the same set of interconnected switches/repeaters is a member of the same broadcast domain. Routers and other higher-layer devices form boundaries between broadcast domains. The notion of broadcast domain should be contrasted with that of collision domain, which would be all nodes on the same set of inter-connected repeaters, divided by switches and learning bridges. Collision domains are generally smaller than, and contained within, broadcast domains. While some data-link-layer devices are able to divide the collision domains, broadcast domains are only divided ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
On-screen Display
An on-screen display (OSD) is an image superimposed on a screen picture, commonly used by modern television sets, VCRs, and DVD players to display information such as volume, channel, and time. History In the past, most adjustments on TV sets were performed with analog controls such as potentiometers and switches. This was used more recently also in monochrome portable TVs. After remote controls were invented, digital adjustments became common. They needed an external display, which was LED, LCD, or VFD based. Including this display increased manufacturing costs. When electronics became more advanced, it became clear that adding some extra devices for an OSD was cheaper than adding a second display device. TV screens had become much bigger and could display much more information than a small second display. OSDs display graphical information superimposed over the picture, which is done by synchronizing the reading from OSD video memory with the TV signal. Some of the first O ...

JPEG
JPEG ( ) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet, and later social media. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG ...

MPEG-4 Part 2
MPEG-4 Part 2, MPEG-4 Visual (formally ISO/IEC 14496-2) is a video compression format developed by the Moving Picture Experts Group (MPEG). It belongs to the MPEG-4 ISO/IEC standards. It uses block-wise motion compensation and a discrete cosine transform (DCT), similar to previous standards such as MPEG-1 Part 2 and H.262/MPEG-2 Part 2. Several popular codecs including DivX, Xvid, and Nero Digital implement this standard. Note that MPEG-4 Part 10 defines a different format from MPEG-4 Part 2 and should not be confused with it. MPEG-4 Part 10 is commonly referred to as H.264 or AVC, and was jointly developed by ITU-T and MPEG. MPEG-4 Part 2 is H.263 compatible in the sense that a basic H.263 bitstream is correctly decoded by an MPEG-4 Video decoder. (MPEG-4 Video decoder is natively capable of decoding a basic form of H.263.) In MPEG-4 Visual, there are two types of video object layers: the video object layer that provides full MPEG-4 functionality, and a reduced functionality ...

Interactive Television
Interactive television is a form of media convergence, adding data services to traditional television technology. It has included on-demand delivery of content, online shopping, and viewer polls. Interactive TV is an example of how new information technology can be integrated vertically into established technologies and commercial structures. History Prior to the development of interactive television, interaction could only be simulated. In the 1950s, there were limited efforts to provide an illusion of interactive experience, most overtly with ''Winky Dink and You'', which encouraged viewers to draw on a vinyl sheet they would attach to a television set. QUBE operated an interactive cable television service in Ohio from 1977 to 1984. An interactive video-on-demand (VOD) television service was proposed in 1986 in Japan, where there were plans to develop an "Integrated Network System" service. It was intended to include various interactive services, including videotelephony, home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
