Slate (broadcasting)
In broadcasting, a slate is a title card listing important metadata of a television program, included before the first frame of the program. The broadcasting equivalent of a film leader, the slate is usually accompanied with color bars and tone, a countdown, and a 2-pop. In videotape workflows, slates help ensure that the tape received is the right one to broadcast (or to project, in the case of digital cinema) or to ingest into a digital playout system. It also provides helpful context for consideration in the re-editing of the material into a larger package. A convention from the videotape era of television broadcasting, the need for slates in a tapeless workflow has largely been usurped by the Material Exchange Format Material Exchange Format (MXF) is a container format for professional digital video and audio media defined by a set of SMPTE standards.

Broadcasting
Broadcasting is the data distribution, distribution of sound, audio audiovisual content to dispersed audiences via a electronic medium (communication), mass communications medium, typically one using the electromagnetic spectrum (radio waves), in a :wikt:one-to-many, one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and radio receiver, receivers. Before this, most implementations of electronic communication (early radio, telephone, and telegraph) were wikt:one-to-one, one-to-one, with the message intended for a single recipient. The term ''broadcasting'' evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metadata
Metadata (or metainformation) is "data that provides information about other data", but not the content of the data itself, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, and permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of Statistical data type, statistical data. * Statistical metadata – also called process data, may ...

Film Leader
A film leader is a length of film attached to the head or tail of a film to assist in threading a Movie projector, projector or telecine. A leader attached to the beginning of a reel is sometimes known as a head leader, or simply head, and a leader attached to the end of a reel known as a tail leader or foot leader, or simply tail or foot. "Film leader", used generically, refers to different types manufactured for many editorial and laboratory uses. For example, some types are used in negative cutting while making A and B rolls for printing. "Painted leader" is perforated film in overall colors, usually white, black, red, blue, or green. These are used for protective head and tail leaders to keep the body of the program material from being damaged. "Fill leader" (also called picture fill, or spacer, or slug film) is used to space out different sections of magnetic audio film stock so they are kept in synchronization with the picture. Typically, this is made from rejected or ret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Bars
SMPTE color bars are a television test pattern used where the NTSC video standard is utilized, including countries in North America. The Society of Motion Picture and Television Engineers (SMPTE) refers to the pattern as Engineering Guideline (EG) 1-1990. Its components are a known standard, and created by test pattern generators. Comparing it as received to the known standard gives video engineers an indication of how an NTSC video signal has been altered by recording or transmission and what adjustments must be made to bring it back to specification. It is also used for setting a television monitor or receiver to reproduce NTSC chrominance and luminance information correctly. A precursor to the SMPTE test pattern was conceived by Norbert D. Larky (1927–2018) and David D. Holmes (1926–2006) of RCA Laboratories and first published in RCA Licensee Bulletin LB-819 on February 7, 1951. U.S. patent 2,742,525 Color Test Pattern Generator (now expired) was awarded on April 17, 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-pop
Used in television production and filmmaking post-production, a 2-pop is a 1 kHz tone that is one frame long and placed 2 seconds before the start of a program. It is a simple and effective method of ensuring synchronization between sound and picture in a video or film. A 2-pop is typically placed at the end of a visual countdown. Only the first frame of the "2" is shown, and the remainder of the 2 seconds prior to the program is black. This provides a unique point of reference where the frame-long image and frame-long sound should align, similar to the way a film clapperboard is used to generate a synchronization point. For example, in a television or video program the first frame of action (FFOA) starts at one hour (typically timecode of 01:00:00:00 in the US, and 10:00:00:00 in the UK), preceding that, 1 frame (or the 2-pop) of tone would be placed at timecode 00:59:58:00 or exactly 2 seconds before first picture. Alternately, in film post-production the leader ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Videotape
Videotape is magnetic tape used for storing video and usually Sound recording and reproduction, sound in addition. Information stored can be in the form of either an analog signal, analog or Digital signal (signal processing), digital signal. Videotape is used in both video tape recorders (VTRs) and, more commonly, videocassette recorders (VCRs) and camcorders. Videotapes have also been used for storing scientific or medical data, such as the data produced by an electrocardiogram. Because video signals have a very high Bandwidth (signal processing), bandwidth, and Tape head, stationary heads would require extremely high tape speeds, in most cases, a helical scan, helical-scan video head rotates against the moving tape to record the data in two dimensions. Tape is a Linear motion, linear method of storing information and thus imposes delays to access a portion of the tape that is not already against the heads. The early 2000s saw the introduction and rise to prominence of high-q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Cinema
Digital cinema is the digital technology used within the film industry to distribute or project motion pictures as opposed to the historical use of reels of motion picture film, such as 35 mm film. Whereas film reels have to be shipped to movie theaters, a digital movie can be distributed to cinemas in a number of ways: over the Internet or dedicated satellite links, or by sending hard drives or optical discs such as Blu-ray discs, then projected using a digital video projector instead of a film projector. Typically, digital movies are shot using digital movie cameras or in animation transferred from a file and are edited using a non-linear editing system (NLE). The NLE is often a video editing application installed in one or more computers that may be networked to access the original footage from a remote server, share or gain access to computing resources for rendering the final video, and allow several editors to work on the same timeline or project. Alternatively a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Playout
In broadcasting, channel playout is the generation of the source signal of a radio or television channel produced by a broadcaster, coupled with the transmission of this signal for primary distribution or direct-to-audience distribution via any network. Such radio or television distribution networks include terrestrial broadcasting (analogue or digital radio), cable networks, satellites (either for primary distribution intended for cable television headends or for direct reception, DTH / DBS), Internet Protocol television, OTT Video, point-to-point transport over managed networks or the public Internet, etc. The television channel playout happens in master control room (MCR) in a playout area, which can be either situated in the central apparatus room or in purposely built playout centres, which can be owned by a broadcaster or run by an independent specialist company that has been contracted to handle the playout for a number of channels from different broadcasters.

Material Exchange Format
Material Exchange Format (MXF) is a container format for professional digital video and audio media defined by a set of SMPTE standards. A typical example of its use is for delivering advertisements to TV stations and tapeless archiving of broadcast TV programs. It is also used as part of the Digital Cinema Package for delivering movies to commercial theaters. Summary MXF, when used in the form of "Operational Pattern OP1A" or "OPAtom", can be used as a ''container'', ''wrapper'' or ''reference file'' format which supports a number of different streams of coded "essence", encoded in any of a variety of video and audio compression formats, together with a metadata wrapper which describes the material contained within the MXF file. Other "Operational Patterns" can contain or reference multiple materials, just like a simple timeline of a video editing program. MXF has full timecode and metadata support and is intended as a platform-agnostic stable standard for future professio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Production Code Number
A production code number, also known as the production code (PC) or episode code, is an alphanumeric designation used to uniquely identify episodes within a television series. As each studio can freely generate its own PC format, it cannot be used universally to identify the show and episode. While, in general, television episodes are filmed in the order they are intended to be aired in, there are circumstances in which this is not the case. In these instances, the production codes can be useful in determining the writers' original intentions. Some "stand-alone" shows, such as ''The Simpsons'', ''Law & Order'' or ''SpongeBob SquarePants'', may air episodes in radically different order to how they are produced, because character development and continuity (fiction), continuity are not major aspects of production. The airing order may in the end be decided by the network, based on ratings, sweeps months, or other networks' competition. Other, more serialized series, like ''Desp ...

Frame Rate
Frame rate, most commonly expressed in frame/s, or FPS, is typically the frequency (rate) at which consecutive images (Film frame, frames) are captured or displayed. This definition applies to film and video cameras, computer animation, and motion capture systems. In these contexts, frame rate may be used interchangeably with and refresh rate, which are expressed in hertz. Additionally, in the context of computer graphics performance, FPS is the rate at which a system, particularly a GPU, is able to generate frames, and refresh rate is the frequency at which a display shows completed frames. In electronic camera specifications frame rate refers to the maximum possible rate frames could be captured, but in practice, other settings (such as exposure time) may reduce the actual frequency to a lower number than the frame rate.
