OpenCable Application Platform
The OpenCable Application Platform, or OCAP, is an operating system layer designed for consumer electronics that connect to a cable television system, the Java-based middleware portion of the platform. Unlike operating systems on a personal computer, the cable company controls what OCAP programs run on the consumer's machine. Designed by CableLabs for the cable networks of North America, OCAP programs are intended for interactive services such as eCommerce, online banking, Electronic program guides, and digital video recording. Cable companies have required OCAP as part of the Cablecard 2.0 specification, a proposal that is controversial and has not been approved by the Federal Communications Commission. Cable companies have stated that two-way communications by third party devices on their networks will require them to support OCAP. The Consumer Electronics Association and other groups argue OCAP is intended to block features that compete with cable company provided services an ...

Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and ...

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 ...

Digital Cable
Digital cable is the distribution of cable television using digital data and video compression. The technology was first developed by General Instrument. By 2000, most cable companies offered digital features, eventually replacing their previous analog-based cable by the mid 2010s. During the late 2000s, broadcast television converted to the digital HDTV standard, which was incompatible with existing analog cable systems. In addition to providing high-definition video, digital cable systems provide more services such as pay-per-view programming, cable internet access and cable telephone services. Most digital cable signals are encrypted, which reduced the incidence of cable television piracy which occurred in analog systems. History In 1990, General Instrument (acquired by Motorola and now owned by ARRIS Group) demonstrated that it was possible to use digital compression to deliver high quality HDTV in a standard 6 MHz television channel. Using the same technology General ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Television
Digital television (DTV) is the transmission of television signals using digital encoding, in contrast to the earlier analog television technology which used analog signals. At the time of its development it was considered an innovative advancement and represented the first significant evolution in television technology since color television in the 1950s. Modern digital television is transmitted in high-definition television (HDTV) with greater resolution than analog TV. It typically uses a widescreen aspect ratio (commonly 16:9) in contrast to the narrower format of analog TV. It makes more economical use of scarce radio spectrum space; it can transmit up to seven channels in the same bandwidth as a single analog channel, and provides many new features that analog television cannot. A transition from analog to digital broadcasting began around 2000. Different digital television broadcasting standards have been adopted in different parts of the world; below are the more widel ...

Cable Television
Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television (also known as terrestrial television), in which the television signal is transmitted over-the-air by radio waves and received by a television antenna attached to the television; or satellite television, in which the television signal is transmitted over-the-air by radio waves from a communications satellite orbiting the Earth, and received by a satellite dish antenna on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation. A "cable channel" (sometimes known as a "cable network") is a tele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interactive Digital Cable Ready
Cable-ready is a designation which indicates that a TV set or other television-receiving device (such as a VCR or DVR) is capable of receiving cable TV without a set-top box. The term originated with analog TV, which uses different frequencies for cable versus over-the-air. This gives more channels, and at lower frequencies, so that early systems did not have to be so broadband and were therefore less expensive to build. For North American cable television frequencies, the VHF channels 2 to 13 are the same, while an extra 51 cable channels exist between there and over-the-air UHF channel 14. Thus, over-the-air channel 14 can be seen on cable channel 65. Conversely, those 51 extra channels (plus an additional five inserted at 95 to 99) cannot be seen at all on a device which is ''not'' cable-ready. A "181-channel tuner" receives 125 on cable (1 to 125), plus 10 (126 to 135) more for digital cable ready TVs, plus the 56 (14 to 69) which are not identical in both (2 to 13) ...

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] |
Embedded Java
Embedded Java refers to versions of the Java program language that are designed for embedded systems. Since 2010 embedded Java implementations have come closer to standard Java, and are now virtually identical to the Java Standard Edition. Since Java 9 customization of the Java Runtime through modularization removes the need for specialized Java profiles targeting embedded devices. History Although in the past some differences existed between embedded Java and traditional PC based Java, the only difference now is that embedded Java code in these embedded systems is mainly contained in constrained memory, such as flash memory. A complete convergence has taken place since 2010, and now Java software components running on large systems can run directly with no recompilation at all on design-to-cost mass-production devices (such as consumers, industrial, white goods, healthcare, metering, smart markets in general) CORE embedded Java API for a unified Embedded Java ecosystem In ord ...

Downloadable Conditional Access System
Downloadable Conditional Access System or DCAS was a proposal advanced by CableLabs for secure software download of a specific Conditional Access client (computer program) which controls digital rights management (DRM) into an OCAP-compliant host consumer media device. The National Cable & Telecommunications Association (NCTA) proposed that DCAS be used as a substitute for physical CableCARDs, a standard also created by CableLabs for which products began appearing in August 2004 as part of industry compliance to the FCC mandate, which in turn is pursuant to the Telecommunications Act of 1996. DCAS is growing in popularity as a less expensive alternative for CableCARD, with major North American operator deployments from Cablevision and Charter. DCAS deployments can be expected to grow in the coming years, thanks to favorable regulatory view from the STELA Reauthorization Act of 2014 and FCC appointing a Downloadable Security Technical Advisory Committee, and wider support for key l ...
