Digital S
D-9 or Digital-S as it was originally known, is a professional digital video videocassette format created by JVC in 1995. It is a direct competitor to Sony's Digital Betacam. Its name was changed to D-9 in 1999 by the SMPTE. It was used to a small extent in Europe and Asia and saw some use in the US, notably by the Fox News Channel, but was a commercial failure compared with Digital Betacam. It was superseded by high definition tapeless formats. Technical details D-9 uses a tape shell of the VHS form factor—though physically incompatible—but the tape itself uses a much higher quality metal particle formulation. The recording system is digital and for video uses DV compression at a 50 Mbit/s bitrate. Video is recorded in 4:2:2 component format at a variety of standard-definition resolutions, in either 4:3 or 16:9 aspect ratios. Audio is recorded as 16-bit/48 kHz PCM with up to four separate channels. Video quality is generally very high; at standard definition, D-9's ...

High Definition Video
High-definition video (HD video) is video of higher display resolution, resolution and quality than Standard-definition television, standard-definition. While there is no standardized meaning for ''high-definition'', generally any video image with considerably more than 480 vertical scan lines (North America) or 576 vertical lines (Europe) is considered high-definition. 480 scan lines is generally the minimum even though the majority of systems greatly exceed that. Images of standard resolution captured at rates faster than normal (60 frames/second North America, 50 fps Europe), by a high-speed camera may be considered high-definition in some contexts. Some television series shot on high-definition video are made to look as if they have been shot on film camera, film, a technique which is often known as filmizing. History The first electronic scanning format, 405-line television system, 405 lines, was the first ''high definition'' television system, since the mechanical systems ...

D-VHS
D-VHS is a digital video recording format developed by JVC, in collaboration with Hitachi, Matsushita, and Philips. The "D" in D-VHS originally stood for "Data", but JVC renamed the format as "Digital VHS". Released in 1998, it uses the same physical cassette format and recording mechanism as S-VHS, but requires higher-quality and more expensive tapes and is capable of recording and displaying both standard-definition and high-definition content. The content data format is in MPEG transport stream, the same data format used for most digital television applications. Design As a final effort for VHS, the D-VHS system had significant advantages as a highly versatile domestic recorder (the other tape-based formats are DV and Digital8, which never gained any traction except as camcorder media), but given the wholesale move to DVD and then hard disk drive (HDD) recording, the format failed to make any headway into the video market. Existing tape media is bulky and more expensive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betacam
Betacam is a family of half-inch professional videocassette products developed by Sony in 1982. In colloquial use, "Betacam" singly is often used to refer to a Betacam camcorder, a Betacam tape, a Betacam video recorder or the format itself. All Betacam variants from (plain) analog recording Betacam to Betacam SP and digital recording Digital Betacam (and additionally, HDCAM and HDCAM SR), use the same shape videocassettes, meaning vaults and other storage facilities do not have to be changed when upgrading to a new format. The cassettes are available in two sizes: S (for Short) and L (for Long). The Betacam camcorder can only load S magnetic tapes, while television studio sized video tape recorders (VTR) designed for video editing can play both S and L tapes. The cassette shell and case for each Betacam cassette is colored differently depending on the format, allowing for easy visual identification. There is also a mechanical key that allows a video tape recorder to identify whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sel-Sync
Sel-Sync or Selective Synchronous recording is the process of selectively using audio tape record heads as play back heads so that new signals can be recorded on other tracks in perfect sync with the existing tracks. Sel-sync recording dramatically changed the recording process allowing overdubbing of individual recorded tracks. Sel-sync along with the multi-track head was invented by Ross S. Snyder at Ampex in 1955. Three problems had to be solved: mechanical alignment, switching of the record track to playback mode and multitrack erase head. The hard problem was the switching of a track between record and playback mode, as the impedance of record heads are quite different from the impedance of play back heads. Prior to Sel-Sync record heads were directly wired to the record electronics and playback heads were directly wired to the playback electronics. Also the designs of the two heads were very different. The problem of switching very low-level/high-impedance circuitry witho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television Studio
A television studio, also called a television production studio, is an installation room in which video productions take place, either for the production of live television and its recording onto video tape or other media such as SSDs, or for the acquisition of raw footage for post-production. The design of a studio is similar to, and derived from, movie studios, with a few amendments for the special requirements of television production. A professional television studio generally has several rooms, which are kept separate for noise and practicality reasons. These rooms are connected via 'talkback' or an intercom, and personnel will be divided among these workplaces. Studio floor The studio floor is the actual stage on which the actions that will be recorded and viewed take place. A typical studio floor has the following characteristics and installations: * decoration and/or sets * professional video camera (sometimes one, usually several), typically mounted on pedestals * mic ...

DVCPRO
DV refers to a family of codecs and tape formats used for storing digital video, launched in 1995 by a consortium of video camera manufacturers led by Sony and Panasonic. In the late 1990s and early 2000s, DV was strongly associated with the transition from analog to digital desktop video production, and also with several enduring "prosumer" camera designs such as the Sony DCR-VX1000, Sony VX-1000. DV is sometimes referred to as #Magnetic tape, MiniDV, which was the most popular tape format using a DV codec during this time. In 2003, DV was joined by a successor format called HDV, which used the same tapes but with an updated video codec; HDV cameras could typically switch between DV and HDV recording modes. In the 2010s, DV rapidly grew obsolete as cameras using memory cards and solid-state drives became the norm, recording at higher bit rate, bitrates and image resolution, resolutions that were impractical for mechanical tape formats. Additionally, as manufacturers switched f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosumer
A prosumer is an individual who both consumes and produces. The term is a portmanteau of the words '' producer'' and ''consumer''. Research has identified six types of prosumers: DIY prosumers, self-service prosumers, customizing prosumers, collaborative prosumers, monetised prosumers, and economic prosumers. The terms ''prosumer'' and ''prosumption'' were coined in 1980 by American futurist Alvin Toffler, and were widely used by many technology writers of the time. Technological breakthrough and a rise in user participation blurs the line between production and consumption activities, with the consumer becoming a prosumer. Definitions and contexts Prosumers have been defined as "individuals who consume and produce value, either for self-consumption or consumption by others, and can receive implicit or explicit incentives from organizations involved in the exchange." The term has since come to refer to a person using commons-based peer production. In the digital and online wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HDCAM SR
HDCAM is a high-definition video digital recording videocassette version of Digital Betacam introduced in 1997 that uses an 8-bit discrete cosine transform (DCT) compressed 3:1:1 recording, in 1080i-compatible down-sampled resolution of 1440×1080, and adding 24p and 23.976 progressive segmented frame (PsF) modes to later models. The HDCAM codec uses rectangular pixels and as such the recorded 1440×1080 content is upsampled to 1920×1080 on playback. The recorded video bit rate is 144 Mbit/s. Audio is also similar, with four channels of AES3 20-bit, 48 kHz digital audio. Like Betacam, HDCAM tapes were produced in small and large cassette sizes; the small cassette uses the same form factor as the original Betamax. The main competitor to HDCAM was the DVCPRO HD format offered by Panasonic, which uses a similar compression scheme and bit rates ranging from 40 Mbit/s to 100 Mbit/s depending on frame rate. HDCAM is standardized as SMPTE 367M, also know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
