Home Cinema
A home cinema, also called home theater, is a home entertainment audio-visual system that seeks to reproduce a movie theater experience and mood using consumer grade electronic video and audio equipment and is set up in a private home. In the 1980s, home cinemas typically consisted of a movie pre-recorded on a LaserDisc or VHS tape; a LaserDisc Player or VCR; and a large-screen cathode-ray tube TV set, although sometimes CRT projectors were used instead. In the 2000s, technological innovations in sound systems, video player equipment, TV screens and video projectors changed the equipment used in home cinema set-ups and enabled home users to experience a higher-resolution screen image, improved sound quality and components that offer users more options (e.g., many Blu-ray players can also stream movies and TV shows over the Internet using subscription services such as Netflix). The development of Internet-based subscription services means that 2020s-era home theatre users ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subwoofer
A subwoofer (or sub) is a loudspeaker designed to reproduce low-pitched audio frequencies, known as bass and sub-bass, that are lower in frequency than those which can be (optimally) generated by a woofer. The typical frequency range that is covered by a subwoofer is about for consumer products, below for professional live sound, and below in THX-certified systems. Thus, one or more subwoofers are important for high-quality sound reproduction as they are responsible for the lowest two to three octaves of the ten octaves that are audible. This very low-frequency (VLF) range reproduces the natural fundamental tones of the bass drum, electric bass, double bass, grand piano, contrabassoon, tuba, in addition to thunder, gunshots, explosions, etc. Subwoofers are never used alone, as they are intended to substitute the VLF sounds of "main" loudspeakers that cover the higher frequency bands. VLF and higher-frequency signals are sent separately to the subwoofer(s) and the mains by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dolby Atmos
Dolby Atmos is a surround sound technology developed by Dolby Laboratories. It expands on existing surround sound systems by adding height channels as well as free-moving sound objects, interpreted as three-dimensional objects with neither horizontal nor vertical limitations. Following the release of Atmos for the cinema market, a variety of consumer technologies have been released under the Atmos brand. The initial cinema Atmos systems used in-ceiling loudspeaker, speakers, then upward-firing speakers (e.g. for soundbars) were introduced as an alternative for consumer products. Atmos is also used on some devices that do not have a height channel, such as headphones, televisions, mobile phones, and Tablet computer, tablets. History The first Dolby Atmos installation was in the El Capitan Theatre in Los Angeles, for the premiere of Brave (2012 film), ''Brave'' in June 2012. Throughout 2012, it saw a limited release of about 25 installations worldwide, with an increase to more t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3D Television
3D television (3DTV) is television that conveys depth perception to the viewer by employing techniques such as stereoscopy, stereoscopic display, free viewpoint television, multi-view display, or any other form of 3D display. Most modern 3D television sets use an active shutter 3D system or a polarized 3D system, and some are Autostereoscopy, autostereoscopic without the need of glasses. , most 3D TV sets and services are no longer available from manufacturers. History The stereoscope was first invented by Sir Charles Wheatstone in 1838.Contributions to the Physiology of Vision.—Part the First. On some remarkable, and hitherto unobserved, Phenomena of Binocular Vision. By CHARLES WHEATSTONE, F.R.S., Professor of Experimental Philosophy in King's College, LondonStereoscopy.com It showed that when two pictures are viewed stereoscopically, they are combined by the brain to produce 3D depth perception. The stereoscope was improved by Louis Jules Duboscq, and a famous picture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-definition Television
High-definition television (HDTV) describes a television or video system which provides a substantially higher image resolution than the previous generation of technologies. The term has been used since at least 1933; in more recent times, it refers to the generation following standard-definition television (SDTV). It is the standard video format used in most broadcasts: Terrestrial television, terrestrial broadcast television, cable television, satellite television. Formats HDTV may be transmitted in various formats: * 720p (): 921,600 pixels * 1080i () interlaced scan: 1,036,800 pixels (≈1.04Mpx). * 1080p () progressive scan: 2,073,600 pixels (≈2.07Mpx). ** Some countries also use a non-standard CTA resolution, such as : 777,600 pixels (≈0.78Mpx) per field or 1,555,200 pixels (≈1.56Mpx) per frame When transmitted at two megapixels per frame, HDTV provides about five times as many pixels as SD (standard-definition television). The increased resolution provides for a cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DVD-Video
DVD-Video is a consumer video format used to store digital video on DVDs. DVD-Video was the dominant consumer home video format in most of the world in the 2000s. As of 2024, it competes with the high-definition Blu-ray Disc, while both receive competition as delivery methods by streaming services such as Netflix and Disney+. Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder (e.g., a DVD player, or a computer DVD drive with a software DVD player). Commercial DVD movies are encoded using a combination of MPEG-2 compressed video and audio of varying formats (often multi-channel formats as described below). Typically, the data rate for DVD movies ranges from 3 to 9.5 Mbit/s, and the bit rate is usually adaptive. DVD-Video was first available in Japan on October 19, 1996 (with major releases beginning December 20, 1996), followed by a release on March 24, 1997, in the United States. The DVD-Video specification was created by the DVD Forum a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rear-projection Television
Rear-projection television (RPTV) is a type of large-screen television display technology. Until approximately 2006, most of the relatively affordable consumer large screen TVs up to used rear-projection technology. A variation is a video projector, using similar technology, which projects onto a screen. Three types of projection systems are used in projection TVs. CRT rear-projection TVs were the earliest, and while they were the first to exceed 40", they were also bulky and the picture was unclear at close range. Newer technologies include DLP (reflective micromirror chip), LCD projectors, Laser TV and LCoS. They are capable of displaying high-definition video up to 1080p resolution, and examples include Sony's SXRD (Silicon X-tal Reflective Display), JVC's D-ILA (Digital Direct Drive Image Light Amplifier) and MicroDisplay Corporation's Liquid Fidelity.

8 mm Film
8 mm film is a motion picture film format in which the film strip is wide. It exists in two main versions – the original standard 8 mm film, also known as regular 8 mm, and Super 8. Although both standard 8 mm and Super 8 are 8 mm wide, Super 8 has a larger image area because of its smaller and more widely spaced perforations. There are also two other varieties of Super 8 – Single 8 mm and Straight-8 – that require different cameras but produce a final film with the same dimensions. Standard 8 The standard 8 mm (also known as regular 8 or double 8) film format was developed by the Eastman Kodak company during the Great Depression and released to the market in 1932 to create a home movie format that was less expensive than 16 mm. Double 8 spools actually contain a 16 mm film with twice as many perforations along each edge as normal 16 mm film; on its first pass through the camera, the film is exposed only alo ...

Home Movies
A home movie is a short amateur film or video typically made just to preserve a visual record of family activities, a vacation, or a special event, and intended for viewing at home by family and friends. Originally, home movies were made on photographic film in formats that usually limited the movie-maker to about three minutes per roll of costly camera film. The vast majority of amateur film formats lacked audio, shooting silent film. The 1970s saw the advent of consumer camcorders that could record an hour or two of video on one relatively inexpensive videocassette which also had audio and did not need to be developed the way film did. This was followed by digital video cameras that recorded to flash memory, and most recently smartphones with video recording capability, made the creation of home movies easier and much more affordable to the average person. The technological boundaries between home-movie-making and professional movie-making are becoming increasingly blurred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
