However, many Comcast (and some other cable TV) customers are finding all of their non-local and non- shopping networks eliminated on various dates, even though only a few are needed for additional digital cable channels.
#DIGITAL TO ANALOG CONVERTER BOX TV#
Differences for cable customers Ĭable TV systems are under no deadline to convert to digital TV. Thomson's model stored three days of TV listings, allowed parental controls, and could set a VCR. The devices showed program details, V-chip ratings and signal strength. Both boxes shown used electronic program guides using Program and System Information Protocol (PSIP). LG Electronics, which took over Zenith Electronics in 1999, showed its model connected to a Zenith TV from 1980, while Thomson Consumer Electronics used an RCA TV from 1987 for its demonstration. Prototypes of the first converter boxes appeared at the NAB show in 2006. Circuit City Chairman Alan McCollough opposed converter boxes, saying people should just buy digital TVs, and television networks should offer only widescreen-format television programming as an incentive to do that. Bob Seidel of CBS said companies (especially in countries other than the US) might use cheaper tuners, and people would need new television antennas for proper reception. Tribune Broadcasting chief technology officer Ira Goldstone said just buying a converter box did not necessarily mean getting the latest technology. And even if people found out what they would have to do, converter boxes might not do the job adequately. Furthermore, he said, too many people were still buying analog TV sets, meaning more demand for converter boxes. The United States government had set up a program to offer consumers a $40 "coupon" which could be used toward the purchase of a coupon-eligible converter box that program ended in July 2009.Īt the Consumer Electronics Association's Entertainment Technology Policy Summit in January 2006, Federal Communications Commission (FCC) Commissioner Jonathan Adelstein said many Americans did not know about the February 17, 2006, deadline for ending analog TV. Additionally, viewers who have newer televisions with built-in digital ATSC tuners will not need an external digital television adapter. Viewers who receive their television signals through cable or satellite were not affected by this change and did not need a digital television adapter (however, see the cable TV exception below). Since many of the low-power TV stations continued to broadcast in analog for a while, consumers who watch low-power stations needed an adapter with an analog passthrough feature that allows the viewer to watch both digital and analog signals. Viewers who watch broadcast television on older analog TV sets must use a digital converter box. On June 12, 2009, all full-power analog television transmissions ended in the United States. Because the DTV transition did nothing to reduce the number of broadcast television system standards (and in fact further complicated them), and due to varying frequency allocations and bandplans, there are many other combinations specific to other countries.
In North America and South Korea, these ATSC tuner boxes convert from ATSC to NTSC, while in most of Europe and other places such as Australia and most Asian countries, they convert from Digital Video Broadcasting (DVB) to PAL, and in Japan, the Philippines and almost all countries in Latin America, they convert from ISDB-T to either NTSC or PAL. It normally does not refer to satellite TV, which has always required a set-top box either to operate the big satellite dish, or to be the integrated receiver/decoder (IRD) in the case of direct-broadcast satellites (DBS). The input digital signal may be over-the-air terrestrial television signals received by a television antenna, or signals from a digital cable system. Some also have an HDMI output since some TVs with HDMI do not have a digital tuner. Type of television tuner to display digital signals on analog sets A digital TV converter boxĪ digital television adapter ( DTA), commonly known as a converter box or decoder box, is a television tuner that receives a digital television (DTV) transmission, and converts the digital signal into an analog signal that can be received and displayed on an analog television set.
