Subtitle (captioning)
Subtitles and captions are lines of dialogue or other text displayed at the bottom of the screen in films, television programs, video games or other visual media. They can be transcriptions of the screenplay, translations of it, or information to help viewers who are deaf or hard-of-hearing understand what is shown. Subtitles refer to a text translation of audio into a different language and are for people who can hear the audio, but may not be able to understand the dialogue. Captions are text in the language of the audio and are designed for anyone unable to hear the audio, they often also contain important sounds that would be unavailable for anyone unable to hear the audio. Open captions are "burnt" into the video and will therefore always be visible, while closed captions (CC) can be toggled on and off according to the preference of the viewer. Methods Subtitles can be rendered as part of the video or separately as graphics or text overlaid on the video. Sometimes ...

Bitmap
In computing, a bitmap is a mapping from some domain (for example, a range of integers) to bits. It is also called a bit array A bit array (also known as bitmask, bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level ... or bitmap index. As a noun, the term "bitmap" is very often used to refer to a particular bitmapping application: the pix-map, which refers to a map of pixels, where each one may store more than two colors, thus using more than one bit per pixel. In such a case, the domain in question is the array of pixels which constitute a digital graphic output device (a screen or monitor). In some contexts, the term ''bitmap'' implies one bit per pixel, whereas ''pixmap'' is used for images with multiple bits per pixel. A bitmap is a type of computer storage, memory organization or image file format used to store dig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scientific Atlanta
Scientific Atlanta, Inc. was a Georgia, United States-based manufacturer of cable television, telecommunications, and broadband equipment. Scientific Atlanta was founded in 1951 by a group of engineers from the Georgia Institute of Technology, and was purchased by Cisco Systems in 2005 for $6.9 billion after Cisco received antitrust clearance for the purchase. The Cisco acquisition of Scientific Atlanta was ranked in the top 10 of largest technology acquisitions in history and was Cisco's largest acquisition to date. Prior to the purchase, Scientific Atlanta had been a Fortune 500 company and was one of the top 25 largest corporations in Georgia. Scientific Atlanta was considered by many to be "the patriarch of Atlanta's technology industry for nearly six decades" and is sometimes referred to as "Atlanta's Microsoft or Hewlett Packard". Products Scientific Atlanta was a supplier of transmission networks for broadband access to the home, set-top cable boxes, cable modems and digit ...

Assistive Technology
Assistive technology (AT) is a term for assistive, adaptive, and rehabilitative devices for people with disabilities and the elderly. Disabled people often have difficulty performing activities of daily living (ADLs) independently, or even with assistance. ADLs are self-care activities that include toileting, mobility (ambulation), eating, bathing, dressing, grooming, and personal device care. Assistive technology can ameliorate the effects of disabilities that limit the ability to perform ADLs. Assistive technology promotes greater independence by enabling people to perform tasks they were formerly unable to accomplish, or had great difficulty accomplishing, by providing enhancements to, or changing methods of interacting with, the technology needed to accomplish such tasks. For example, wheelchairs provide independent mobility for those who cannot walk, while assistive eating devices can enable people who cannot feed themselves to do so. Due to assistive technology, disabled pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
