BD-J
BD-J, or Blu-ray Disc Java, is a specification supporting Java ME (specifically the Personal Basis Profile of the Connected Device Configuration or CDC) Xlets for advanced content on Blu-ray Disc and the Packaged Media profile of Globally Executable MHP (GEM). BD-J allows bonus content on Blu-ray Disc titles to be far more sophisticated than bonus content provided by standard DVD, including network access, picture-in-picture and access to expanded local storage. Collectively, these features (other than internet access) are referred to as "Bonus View", and the addition of internet access is called "BD Live". BD-J was developed by the Blu-ray Disc Association. All Blu-ray Disc players supporting video content are required by the specification to support BD-J. Starting on October 31, 2007, all ''new'' players are required to have hardware support for the "Bonus View" features, but the players may require future firmware updates to enable the features. "BD Live" support is always opti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blu-ray Disc
The Blu-ray Disc (BD), often known simply as Blu-ray, is a Digital media, digital optical disc data storage format. It was invented and developed in 2005 and released on June 20, 2006 worldwide. It is designed to supersede the DVD format, and capable of storing several hours of high-definition video (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X and Series S, Xbox Series X. The name "Blu-ray" refers to the blue laser (which is actually a Violet (color), violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs. The polycarbonate disc is in diameter and thick, the same size as DVDs and Compact disc, CDs. Conventional or pre-BD-XL Blu-ray Discs contain 25 gigabyte, GB per layer, ...

HD DVD
HD DVD (short for High Definition Digital Versatile Disc) is an obsolete high-density optical disc format for storing data and playback of high-definition video. Supported principally by Toshiba, HD DVD was envisioned to be the successor to the standard DVD format. HD DVD employed a blue laser with a shorter wavelength (with the exception of the 3× DVD and HD REC variants), and it stored about 3.2 times as much data per layer as its predecessor (maximum capacity: 15 GB per layer compared to 4.7 GB per layer on a DVD). The format was commercially released in 2006 and fought a protracted format war with rival Blu-ray. On February 19, 2008, Toshiba abandoned the format, announcing it would no longer manufacture HD DVD players and drives. The HD DVD Promotion Group was dissolved on March 28, 2008. The HD DVD physical disc specifications (but not the codecs) were used as the basis for the China Blue High-definition Disc (CBHD) formerly called CH-DVD. History In the lat ...

Java TV
Java TV is a Java-based software framework designed for use on TV set-top boxes, based on components called Xlets. It is currently used only on the Connected Device Configuration, specifically for iTV applications development. The API includes the Xlet classes in the package javax.tv.xlet. Other packages of the public API include # javax.tv.graphics - provides a simple rendering canvas # javax.tv.locator - provides a locator in the style of a URL for services and media, such as service:/SERV1 # javax.tv.service - defines a mechanism for service information (SI) databases and APIs representing the SI elements, such as the TV channels and media available for playback. Criticisms While the framework is general, Sun currently provides support only on Java ME. For some subjects, such as media locators, it is in effect superseded by other locator standards on platforms such as BD-J. A point of confusion is that in platforms supported as of 2008, examples such as the SvcDispXlet example f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java Platform, Micro Edition
Java Platform, Micro Edition or Java ME is a computing platform for development and deployment of portable code for embedded and mobile devices (micro-controllers, sensors, gateways, mobile phones, personal digital assistants, TV set-top boxes, printers). Java ME was formerly known as Java 2 Platform, Micro Edition or J2ME. As of December 22, 2006, the Java ME source code is licensed under the GNU General Public License, and is released under the project name phoneME. The platform uses the object-oriented Java programming language. It is part of the Java software-platform family. Java ME was designed by Sun Microsystems, acquired by Oracle Corporation in 2010; the platform replaced a similar technology, PersonalJava. Originally developed under the Java Community Process as JSR 68, the different flavors of Java ME have evolved in separate JSRs. Oracle provides a reference implementation of the specification, but has tended not to provide free binary imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Content
Advanced Content provides interactivity in the HD DVD optical disc format. Advanced Content is used to provide interactive menus and "special features" such as additional bonus/extras content and games for HD DVD (one of the high-definition video formats). The Advanced Content runtime engine is responsible for responding to user navigation input (e.g., from a remote control) as well as events set to occur during playback of a movie, controlling all actions and interactive properties during the playback of a movie. The Advanced Content specification was developed by Microsoft and Disney with input from other members of the DVD Forum including Toshiba and Sonic Solutions. Advanced Content also enables network access to download additional content and access to persistent storage which is used for storing bookmarks and other state information. The ability to play back Advanced Content is a mandatory part of the HD DVD-Video specification. Its features were defined by content providers ...

Connected Device Configuration
The Connected Device Configuration (CDC) is a specification of a framework for Java ME applications describing the basic set of libraries and virtual-machine features that must be present in an implementation. The CDC is combined with one or more profiles to give developers a platform for building applications on embedded devices ranging from pagers up to set-top boxes.CDC Overview http://java.sun.com/javame/technology/cdc/overview.jsp The CDC was developed under the Java Community Process as JSR 36JSR 36, CDC 1.0.2 http://www.jcp.org/en/jsr/detail?id=36 (CDC 1.0.2) and JSR 218JSR 218, CDC 1.1.2 http://www.jcp.org/en/jsr/detail?id=218 (CDC 1.1.2). Typical requirements Devices that support CDC typically include a 32-bit CPU with about 2 MB of RAM, and 2.5 MB of ROM available for the Java application environment. The reference implementations for CDC profiles are based on Linux running on an Intel-compatible PC, and optimized implementations are available for a variety of ...

Globally Executable MHP
Globally Executable MHP (GEM) is a Digital Video Broadcasting, DVB specification of a Java (programming language), Java based middleware for TV broadcast receivers, IPTV terminals and Blu-ray players. GEM is an ETSI standard (ETSI TS 102 819, ETSI TS 102 728) and an ITU "Recommendation” (ITU-T J.202). GEM defines a set of common functionalities which are independent from the signaling and protocols of a specific transmission network and enables to write interoperable Java applications for TV. GEM is not intended to be directly implemented, but rather forms the basis for broader specifications targeting a particular network infrastructure (e.g. US cable) or class of device (e.g. Blu-ray Disc players). GEM defines profiles for different device classes (targets) these define the set of available features of GEM for this device class. Currently GEM defines targets (API profiles) for broadcast, packaged media (Blu-Ray) and IPTV. Combinations of these targets can be combined into a hybr ...

Xlet
An Xlet is very similar to a Java applet and is originally introduced in Sun Microsystems's Java TV specification to support applications for Digital TV. Though Xlet looks superficially different from other application models in Java such as applet and MIDlet, it is actually meant to be a generalization of such models. The ''X'' in Xlet means an unknown, meaning that the Xlet framework may be used in any context rather than specific to Digital TV. Accordingly, Xlet was later re-introduced as a part of the Personal Basis Profile in the package, which is slightly different from the original design in the Java TV specification. The Xlet provision of a pause/resume feature is essential for a set-top box (STB) environment, which has limited memory resources and restrictions on bandwidth from the head-end provider. The current practice and intent of the Xlet framework is to provide downloadable applications for Personal Basis Profile (PBP) platforms. In particular, the BD-J platform uses ...

Space Invaders
is a 1978 shoot 'em up arcade game developed by Tomohiro Nishikado. It was manufactured and sold by Taito in Japan, and licensed to the Midway division of Bally for overseas distribution. ''Space Invaders'' was the first fixed shooter and set the template for the shoot 'em up genre. The goal is to defeat wave after wave of descending aliens with a horizontally moving laser to earn as many points as possible. Designer Nishikado drew inspiration from North American target shooting games like '' Breakout'' (1976) and ''Gun Fight'' (1975), as well as science fiction narratives such as the novel ''The War of the Worlds'' (1897), the anime ''Space Battleship Yamato'' (1974), and the movie ''Star Wars'' (1977). To complete development of the game, he had to design custom hardware and development tools. Upon release, ''Space Invaders'' was an immediate commercial success; by 1982, it had grossed $3.8 billion (equivalent to over adjusted for inflation ), with a net profit of $ ...

HTTP
The Hypertext Transfer Protocol (HTTP) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser. Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989 and summarized in a simple document describing the behavior of a client and a server using the first HTTP protocol version that was named 0.9. That first version of HTTP protocol soon evolved into a more elaborated version that was the first draft toward a far future version 1.0. Development of early HTTP Requests for Comments (RFCs) started a few years later and it was a coordinated effort by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), with work later moving to ...
