DTV Transition In The United States
The digital transition in the United States was the switchover from analog to exclusively digital broadcasting of terrestrial television programming. According to David Rehr, then president and CEO of the National Association of Broadcasters, this transition represented "the most significant advancement of television technology since color TV was introduced." For full-power TV stations, the transition went into effect on June 12, 2009, with stations ending regular programming on their analog signals no later than 11:59 p.m. local time that day. Under the Digital Transition and Public Safety Act of 2005, full-power broadcasting of analog television in the United States was initially planned to have ceased after February 17, 2009. To help U.S. consumers through the conversion, the Act also established a federally sponsored DTV Converter Box Coupon Program. The DTV Delay Act changed the mandatory analog cutoff date to June 12, 2009, although stations were permitted to cea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Analog TV
Analog television is the original television technology that uses analog signals to transmit video and audio. In an analog television broadcast, the brightness, colors and sound are represented by amplitude, phase and frequency of an analog signal. Analog signals vary over a continuous range of possible values which means that electronic noise and interference may be introduced. Thus with analog, a moderately weak signal becomes snowy and subject to interference. In contrast, picture quality from a digital television (DTV) signal remains good until the signal level drops below a threshold where reception is no longer possible or becomes intermittent. Analog television may be wireless (terrestrial television and satellite television) or can be distributed over a cable network as cable television. All broadcast television systems used analog signals before the arrival of DTV. Motivated by the lower bandwidth requirements of compressed digital signals, beginning in the 20 ...

Video Capture
Video capture is the process of converting an analog video signal—such as that produced by a video camera, DVD player, or television tuner—to digital video and sending it to local storage or to external circuitry. The resulting digital data are referred to as a ''digital video stream'', or more often, simply ''video stream''. Depending on the application, a video stream may be recorded as computer files, or sent to a video display, or both. Devices Special electronic circuitry is required to capture video from analog video sources. At the system level this function is typically performed by a dedicated video capture device. Such devices typically employ integrated circuit video decoders to convert incoming video signals to a standard digital video format, and additional circuitry to convey the resulting digital video to local storage or to circuitry outside the video capture device, or both. Depending on the device, the resulting video stream may be conveyed to external circui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rio Grande Valley (Texas)
The Lower Rio Grande Valley ( es, Valle del Río Grande), commonly known as the Rio Grande Valley or locally as the Valley or RGV, is a region spanning the border of Texas and Mexico located in a floodplain of the Rio Grande near its mouth. The region includes the southernmost tip of South Texas and a portion of northern Tamaulipas, Mexico. It consists of the Brownsville, Harlingen, Weslaco, Pharr, McAllen, Edinburg, Mission, San Juan, and Rio Grande City metropolitan areas in the United States and the Matamoros, Río Bravo, and Reynosa metropolitan areas in Mexico. The area is generally bilingual in English and Spanish, with a fair amount of Spanglish due to the region's diverse history and transborder agglomerations It is home to some of the poorest cities in the nation, as well as many unincorporated, persistent poverty communities called ''colonias''. A large seasonal influx occurs of "winter Texans" — people who come down from the north for the winter and then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DTV Border Fix Act
The DTV Border Fix Act () was a bill introduced to the U.S. Congress in 2007. It would have allowed all television stations within 80 kilometers (50 miles) of the Mexican border, in areas such as San Diego and the Rio Grande Valley, to keep their analog signals active for another five years. The bill passed the Senate but did not pass the House. from OpenCongress.org See also *Digital television transition in the United States

Bill (law)
A bill is proposed legislation under consideration by a legislature. A bill does not become law until it is passed by the legislature as well as, in most cases, approved by the executive. Once a bill has been enacted into law, it is called an '' act of the legislature'', or a ''statute''. Bills are introduced in the legislature and are discussed, debated and voted upon. Usage The word ''bill'' is primarily used in Anglophone United Kingdom and United States, the parts of a bill are known as ''clauses'', until it has become an act of parliament, from which time the parts of the law are known as ''sections''. In Napoleonic law nations (including France, Belgium, Luxembourg, Spain and Portugal), a proposed law may be known as a "law project" (Fr. ''projet de loi''), which is a government-introduced bill, or a "law proposition" (Fr. ''proposition de loi''), a private member's bill. For example the Dutch parliamentary system does not make this terminological distinction (''wetsontw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MediaFLO
MediaFLO was a technology developed by Qualcomm for transmitting audio, video and data to portable devices such as mobile phones and personal televisions, used for mobile television. In the United States, the service powered by this technology was branded as FLO TV. Broadcast data transmitted via MediaFLO includes live, real time audio and video streams, as well as scheduled video and audio clips and shows. The technology could also carry Internet Protocol datacast application data, such as stock market quotes, sports scores, and weather reports. In October 2010, Qualcomm announced it was suspending new sales of the service to consumers. In December 2010, AT&T announced that it will purchase Qualcomm's FCC licenses in the 700 MHz band. FLO TV discontinued service on March 27, 2011. Overview The "FLO" in MediaFLO stood for ''Forward Link Only'', meaning that the data transmission path is one way, from the tower to the device.

Qualcomm
Qualcomm () is an American multinational corporation headquartered in San Diego, California, and incorporated in Delaware. It creates semiconductors, software, and services related to wireless technology. It owns patents critical to the 5G, 4G, CDMA2000, TD-SCDMA and WCDMA mobile communications standards. Qualcomm was established in 1985 by Irwin M. Jacobs and six other co-founders. Its early research into CDMA wireless cell phone technology was funded by selling a two-way mobile digital satellite communications system known as Omnitracs. After a heated debate in the wireless industry, the 2G standard was adopted with Qualcomm's CDMA patents incorporated. Afterwards there was a series of legal disputes about pricing for licensing patents required by the standard. Over the years, Qualcomm has expanded into selling semiconductor products in a predominantly fabless manufacturing model. It also developed semiconductor components or software for vehicles, watches, laptops, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
700 Mhz Wireless Spectrum Auction
The United States 700 MHz FCC wireless spectrum auction, officially known as Auction 73, was started by the Federal Communications Commission (FCC) on January 24, 2008 for the rights to operate the 700 MHz radio frequency band in the United States. The details of process were the subject of debate among several telecommunications companies, including Verizon Wireless, AT&T Mobility, as well as the Internet company Google. Much of the debate swirled around the open access requirements set down by the Second Report and Order released by the FCC determining the process and rules for the auction. All bidding was required by law to commence by January 28. Overview Full-power TV stations were forced to transition to digital broadcasting in order to free 108 MHz of radio spectrum for newer wireless services. Most analog broadcasts ceased on June 12, 2009. The 700 MHz spectrum was previously used for analog television broadcasting, specifically UHF channels ...

ATSC Standards
Advanced Television Systems Committee (ATSC) standards are an American set of standards for digital television transmission over terrestrial, cable and satellite networks. It is largely a replacement for the analog NTSC standard and, like that standard, is used mostly in the United States, Mexico, Canada, and South Korea. Several former NTSC users, such as Japan, have not used ATSC during their digital television transition, because they adopted other systems such as ISDB developed by Japan, and DVB developed in Europe, for example. The ATSC standards were developed in the early 1990s by the Grand Alliance, a consortium of electronics and telecommunications companies that assembled to develop a specification for what is now known as HDTV. The standard is now administered by the Advanced Television Systems Committee. It includes a number of patented elements, and licensing is required for devices that use these parts of the standard. Key among these is the 8VSB modula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Channel Election
A digital channel election was the process by which television stations in the United States chose which physical radio-frequency TV channel they would permanently use after the analog shutdown in 2009. The process was managed and mandated by the Federal Communications Commission for all full-power TV stations. Low-powered television (LPTV) stations are going through a somewhat different process, and are also allowed to flash-cut to digital. Process Stations could choose to keep their initial digital TV channel allocation, do a flash-cut to their former analog TV channel, or attempt to select another channel, often an analog channel or pre-transition digital channel from another station that had been orphaned. Stations on channels 52 to 69 did not have the first option, as the FCC and then the U.S. Congress revoked them from the bandplan. Many stations have chosen to keep their new channels permanently, after being forced to buy all new transmitters and television an ...
