Streamed
Streaming media is multimedia that is delivered and consumed in a continuous manner from a source, with little or no intermediate storage in network elements. ''Streaming'' refers to the delivery method of content, rather than the content itself. Distinguishing delivery method from the media applies specifically to telecommunications networks, as most of the traditional media delivery systems are either inherently ''streaming'' (e.g. radio, television) or inherently ''non-streaming'' (e.g. books, videotape, audio CDs). There are challenges with streaming content on the Internet. For example, users whose Internet connection lacks sufficient bandwidth may experience stops, lags, or poor buffering of the content, and users lacking compatible hardware or software systems may be unable to stream certain content. With the use of buffering of the content for just a few seconds in advance of playback, the quality can be much improved. Livestreaming is the real-time delivery of con ...

Livestreaming
Livestreaming is streaming media simultaneously recorded and broadcast in real-time over the internet. It is often referred to simply as streaming. Non-live media such as video-on-demand, vlogs, and YouTube videos are technically streamed, but not live-streamed. Livestream services encompass a wide variety of topics, from social media to video games to professional sports. Platforms such as Facebook Live, Periscope, Kuaishou, Douyu, bilibili and 17 include the streaming of scheduled promotions and celebrity events as well as streaming between users, as in videotelephony. Sites such as Twitch have become popular outlets for watching people play video games, such as in esports, Let's Play-style gaming, or speedrunning. Live coverage of sporting events is a common application. User interaction via chat rooms forms a major component of livestreaming. Platforms often include the ability to talk to the broadcaster or participate in conversations in chat. Many chat rooms also consist ...

Streaming Television
Streaming television is the digital distribution of television content, such as TV shows, as streaming media delivered over the Internet. Streaming television stands in contrast to dedicated terrestrial television delivered by over-the-air aerial systems, cable television, and/or satellite television systems. History Up until the 1990s, it was not thought possible that a television programme could be squeezed into the limited telecommunication bandwidth of a copper telephone cable to provide a streaming service of acceptable quality, as the required bandwidth of a digital television signal was around 200Mbit/s, which was 2,000 times greater than the bandwidth of a speech signal over a copper telephone wire. Streaming services were only made possible as a result of two major technological developments: MPEG ( motion-compensated DCT) video compression and asymmetric digital subscriber line (ADSL) data transmission. The first worldwide live-streaming event was a radio live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Real-time Text
Real-time text (RTT) is text messaging, text transmitted instantly as it is typed or created. Recipients can immediately read the message while it is being written, without waiting. Real-time text is used for conversational text, in collaboration, and in live captioning. Technologies include TDD/TTY devices for the deaf, live captioning for TV, Text over IP (ToIP), some types of instant messaging, captioning for telephony/video teleconferencing, telecommunications relay services including ip-relay, transcription services including Remote CART, TypeWell, Collaborative real-time editing, collaborative text editing, Stream (computing), streaming text applications, Next Generation 9-1-1, next-generation 9-1-1/1-1-2 emergency service. Obsolete TDD/TTY devices are being replaced by more modern real-time text technologies, including Text over IP, ip-relay, and instant messaging. During 2012, the Real-Time Text Taskforce (R3TF) designed a standard international symbol to represent real-tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Computer
A personal computer (PC) is a multi-purpose microcomputer whose size, capabilities, and price make it feasible for individual use. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. Primarily in the late 1970s and 1980s, the term home computer was also used. Institutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with the machines. While personal computer users may develop their own applications, usually these systems run commercial software, free-of-charge software ("freeware"), which is most often proprietary, or free and open-source software, which is provided in "ready-to-run", or binary, form. Software for personal computers is typically developed and distributed independently from the hardware or operating system ma ...

Cloud Gaming
Cloud gaming, sometimes called gaming on demand or gaming-as-a-service or game streaming, is a type of online gaming that runs video games on remote servers and streams them directly to a user's device, or more colloquially, playing a game remotely from a cloud. It contrasts with traditional means of gaming, wherein a game runs locally on a user's video game console, personal computer, or mobile device. Background Cloud gaming platforms operate in a similar manner to remote desktops and video on demand services; games are stored and executed remotely on a provider's dedicated hardware, and streamed as video to a player's device via client software. The client software handles the player's inputs, which are sent back to the server and executed in-game. Some cloud gaming services are based on access to a virtualized Windows environment, allowing users to download and install games and software as they normally would on a local computer. Cloud gaming can be advantageous as it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Video
Digital video is an electronic representation of moving visual images (video) in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images in the form of analog signals. Digital video comprises a series of digital images displayed in rapid succession. Digital video is audio and video mixed together to make a production. the data gathered used to create a video, rather than a series of photos put together. Digital video have many advantages such as easy copying, multicasting, easy sharing and storage. Video recorded on tape is used on a computer on media player. Digital video is made of images displayed rapidly frequencies of 15, 24,30, and 60 frames per second. Digital video was first introduced commercially in 1986 with the Sony D1 format, which recorded an uncompressed standard-definition component video signal in digital form. In addition to uncompressed formats, popular compressed digital video formats today include H.264 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video On Demand
Video on demand (VOD) is a media distribution system that allows users to access videos without a traditional video playback device and the constraints of a typical static broadcasting schedule. In the 20th century, broadcasting in the form of over-the-air programming was the most common form of media distribution. As Internet and IPTV technologies continued to develop in the 1990s, consumers began to gravitate towards non-traditional modes of content consumption, which culminated in the arrival of VOD on televisions and personal computers. Unlike broadcast television, VOD systems initially required each user to have an Internet connection with considerable bandwidth to access each system's content. In 2000, the Fraunhofer Institute IIS developed the JPEG2000 codec, which enabled the distribution of movies via Digital Cinema Packages. This technology has since expanded its services from feature-film productions to include broadcast television programmes and has led to lower bandw ...

The Crab Nebula NASA
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a ...

Los Angeles Times
The ''Los Angeles Times'' (abbreviated as ''LA Times'') is a daily newspaper that started publishing in Los Angeles in 1881. Based in the LA-adjacent suburb of El Segundo since 2018, it is the sixth-largest newspaper by circulation in the United States. The publication has won more than 40 Pulitzer Prizes. It is owned by Patrick Soon-Shiong and published by the Times Mirror Company. The newspaper’s coverage emphasizes California and especially Southern California stories. In the 19th century, the paper developed a reputation for civic boosterism and opposition to labor unions, the latter of which led to the bombing of its headquarters in 1910. The paper's profile grew substantially in the 1960s under publisher Otis Chandler, who adopted a more national focus. In recent decades the paper's readership has declined, and it has been beset by a series of ownership changes, staff reductions, and other controversies. In January 2018, the paper's staff voted to unionize and final ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muzak Holdings
Muzak is an American brand of background music played in retail stores and other public establishments. The name has been in use since 1934, and has been owned by a division or subsidiary of one or another company ever since. In 1981, Westinghouse bought the company and ran it until selling it to the Fields Company of Chicago, publishers of the ''Chicago Sun-Times'', on September 8, 1986. Formerly owned by Muzak Holdings, the brand was purchased in 2011 by Mood Media in a deal worth US$345 million. Muzak was based in various Seattle, Washington locations from 1986 to 1999, after which it moved its headquarters to South Carolina in 2000. The word ''Muzak'' has been a registered trademark since December 21, 1954, of Muzak LLC. In the United States, due in part to the company’s market dominance, ''Muzak'' has come to be used to refer to most forms of background music, regardless of source. It may also be referred to as "elevator music" or "lift music". Though Muzak Holdings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Owen Squier
Major General George Owen Squier (March 21, 1865 – March 24, 1934) was born in Dryden, Michigan, United States. He graduated from the United States Military Academy in the Class of 1887 and received a Ph.D. from Johns Hopkins University in 1893. He was famous both in the United States and in Europe as a soldier, a scientist and as an inventor. He is known for what today is called Muzak. Life and military career George Squier wrote and edited many books and articles on the subject of radio and electricity. An inventor, he and Dartmouth professor Albert Cushing Crehore developed a magneto-optical streak camera "The Polarizing Photo-chronograph" in 1896 to measure the speed of projectiles both inside a cannon and directly after they left the cannon barrel. This was one of the earliest photonic programs. They also worked to develop synchronous AC telegraphic systems. His biggest contribution was that of telephone carrier multiplexing in 1910 for which he was elected to the Natio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Théâtrophone
Théâtrophone ("the theatre phone") was a telephonic distribution system available in portions of Europe that allowed the subscribers to listen to opera and theatre performances over the telephone lines. The théâtrophone evolved from a Clément Ader invention, which was first demonstrated in 1881, in Paris. Subsequently, in 1890, the invention was commercialized by Compagnie du Théâtrophone, which continued to operate until 1932. Origin The origin of the théâtrophone can be traced to a telephonic transmission system demonstrated by Clément Ader at the 1881 International Exposition of Electricity in Paris. The system was inaugurated by the French President Jules Grévy, and allowed broadcasting of concerts or plays. Ader had arranged 80 telephone transmitters across the front of a stage to create a form of binaural stereophonic sound. It was the first two-channel audio system, and consisted of a series of telephone transmitters connected from the stage of the Paris Oper ...
