    • Are Digital TV and HDTV the same thing?
      No!  You can purchase a digital television (DTV) and it not be an HDTV. Digital television has a better quality than the tradition analog TV. High-definition television (HDTV) is simply a better-quality version of digital TV.

      All televisions sold in the U.S. are now digital. HDTV's are usually the one's that have the widescreen format. If you're confused at the store, just look for the "HDTV" wording on the television or ask for help.

       

    • What is digital television (DTV)?
      Digital television (DTV) is a new type of broadcasting technology that is transforming television as we now know it. By transmitting the information used to make a TV picture and sound as "data bits" (like a computer), a digital broadcaster can carry more information than is currently possible with traditional analog broadcast technology. The difference between analog and digital broadcasting is similar to that between compact discs and cassette tapes.

      Digital TV offers a better viewing experience with vastly improved picture and sound quality. DTV is also more efficient than analog TV technology so broadcasters will be able to produce additional signals using the DTV system. Remember, that while DTV is better than traditional analog, DTV is not the same as HDTV!

      KBTX Media broadcasts in digital television on Suddenlink cable channel 5, Direct TV satellite channel 3, and "over-the-air" (through your antenna) on channel 50.

    • What is analog television?
      Analog television service is the traditional method of transmitting TV signals and has been the standard broadcast technology since the inception of television. Analog television service isn’t as efficient as DTV. It uses up much more valuable spectrum that - once the DTV transition is completed - will be provided to public safety organizations, such as first responders including fire and police departments. The remaining spectrum will be auctioned off for the production of new services.

      Analog broadcasting will continue until the end of the transition period, which currently is set for February 17, 2009. Most television stations will continue broadcasting their programming in both analog and digital signals until then.

      What are the benefits of digital television?
      Digital technology allows the transmission of pictures with higher resolution for dramatically better picture and sound quality than currently available. DTV also allows the transmission of several TV programs at once - called "multicasting." DTV technology can also be used to provide interactive video and data services that are not possible with analog technology.

      An equally important, but often overlooked benefit of DTV is that it will free up scarce and valuable spectrum for public safety and new wireless services. This is possible because the modern technology of DTV is more efficient than analog TV technology, allowing for many new and critical uses of this very limited resource.
    • What is the digital TV transition?
      The digital TV (DTV) transition is the switch from traditional analog TV to digital TV, a modern technology with many benefits. February 17, 2009 is the deadline by which traditional analog TV service will be shut off. The DTV service will be what remains. Most television stations are currently broadcasting their programming in both analog and digital until February 17, 2009. Analog television sets receiving free, over-the-air programming will still work after that date, but owners of these TVs will need to acquire converter boxes to change digital broadcasts back into the old analog format. Converter boxes will be available from consumer electronics retailers at that time. If you’re a cable or satellite subscriber, you aren’t likely to be affected by the DTV transition, but you may want to check with your cable or satellite provider if you have questions about your service

      When will the DTV transition be complete?
      The final transition is February 17, 2009. At that point, broadcasting of the current "analog" channels will end and the spectrum that had been used for analog transmission will be put to other uses. Until the transition to DTV is complete, television stations will continue broadcasting on both their digital and analog channels.

      Will I need a new TV?
      Your current television will work as it does now until analog broadcasting stops. Even after the transition is over, your current TV will not become obsolete. A set-top converter box can be used to receive broadcast DTV signals and change them into the format of your current television. In addition, if you use your analog set with a pay service like cable or satellite, it should continue to work as it always has.

      How do I get a set-top converter box for my analog television?
      Click here for more information how you can get the converter boxes.
    • Beginning on January 1, 2008, U.S. households can request up to two coupons for the converter boxes, which will be valued at $40 each. Coupons will be mailed via the U.S. Postal Service, and consumers will have approximately three months to redeem them. Consumers who wish to retain their analog television sets may also switch to a cable, satellite or telecommunications service provider.

      What is the Digital-to-Analog Converter Box Assistance Program?
      On February 18, 2009, broadcast television stations will stop analog broadcasting and complete the transition to digital broadcasting. If you don’t subscribe to cable or satellite services, you’ll need either a television set capable of receiving DTV programming, or a digital-to-analog converter box.

      Digital-to-analog converter boxes will make DTV signals viewable on analog TV sets. These converter boxes will be available in retail stores during the transition. The National Telecommunications and Information Administration (NTIA) of the U.S. Department of Commerce is developing rules that will allow households to obtain coupons that can be applied toward the purchase of digital-to-analog converter boxes. For more information on the Digital-to-Analog Converter Box Assistance program, visit NTIA's DTV Coupon FAQ.

      How can I prepare for the DTV transition?
      Preparing for the DTV transition is easy and requires one of three steps by February 17, 2009:
        • Purchase a new television set with a built in digital tuner (a digital TV).
        • Purchase a digital-to-analog converter box that plugs into an existing television. The boxes, which are expected to cost between $50 - 70 will be available for purchase in 2008. Beginning on January 1, 2008, U.S. households can request up to two coupons valued at $40 each. Each coupon can go toward the purchase of a single set-top converter box that will allow you to continue watching free "over-the-air" television on an analog set.
        • Subscribe to a cable, satellite or telecommunications service provider if all desired local broadcast stations are carried by that service.
        Any of these steps will ensure that "over-the-air" television consumers will continue to receive programming.

        What is the difference between integrated DTVs and DTV monitors?
        An Integrated DTV set is a digital television with a built-in DTV receiver. If you have an Integrated DTV and live in an area served by a DTV broadcast station, you won’t need any additional equipment, with the exception of an antenna to receive over-the-air DTV broadcast programming. Integrated TVs can usually receive and display current analog signals.

        In contrast, a DTV-Ready monitor isn’t capable of receiving over-the-air DTV broadcast programming without additional equipment. A DTV set-top decoder must be connected between the antenna and the monitor to receive and display over-the-air DTV programming.

        Confirm with your retailer that the DTV receiver or set-top decoder is compatible with the DTV monitor that you’re purchasing. Most monitors have a built in analog receiver and can dis
    • from DVD players and VCRs.

      What do DTV sets look like and what will they cost?
      Most DTV sets have wider, more rectangular screens than current analog TVs. This widescreen format allows for images that are more like those shown in a movie theater. Like current TV sets, a range of sizes is available.

      As with most new consumer electronics technologies, DTV sets have become less expensive since their introduction. Prices are expected to continue to decrease over time and will vary depending on screen size, display technology, and other features.

      Will I need a special antenna to receive DTV over-the-air?
      In general, dependable reception of DTV will require the same type of signal reception equipment that currently works to provide good quality reception of analog TV signals. If you now need a roof-top antenna to receive television, the same antenna generally will be needed to receive DTV. For specific information on using an antenna to receive local television broadcast channels visit www.antennaweb.org.

      Do I already have DTV via digital cable or satellite?
      You may have DTV if you subscribe to the digital package and get digital programming. But, digital cable and satellite service aren’t necessarily "DTV." Your cable or satellite system may be using digital technology as a more efficient way of delivering programming to your analog TV set. If you have an analog television set, then you aren’t viewing true DTV, even though the signal you’re watching may be somewhat improved. In order to view true DTV and enjoy all the attributes of digital television service, you must view television signals on a new DTV set.
    • Similarly, in order to view programs in high-definition (HDTV), you must be equipped with a TV set capable of displaying pictures in high-definition. Your cable or satellite set-top box or the CableCARD from your cable company must provide HDTV channels. Otherwise, you must have an antenna that can receive digital HDTV signals over the air. Check with your cable or satellite provider if you have questions about your service.

      What about my VCR, DVD player and camcorder? Will I be able to use them with an HDTV or DTV set?
      HDTV and DTV sets are "backward compatible," meaning existing analog equipment (VCRs, DVD players, camcorders, video games, etc.) will work on digital TV sets, but not in high definition. Their video will be displayed in the maximum resolution that is available with each product.

自由電子報 - 11年來首見 南韓逆差130億美元

      11年來首見 南韓逆差130億美元

      〔編譯羅倩宜、張沛元、記者王孟倫/綜合報導〕南韓去年十二月出口跌逾十五%,已連續兩個月下滑,更出現十一年以來首次貿易赤字。南韓總統李明博週五宣布連串改革措施,包括成立緊急經濟政府機制、增加十一兆韓元助中小企業融資擔保與遭企業留職停薪勞工由政府負擔四分之三的薪資等。

      學者看好台灣仍維持順差

      南韓殷鑑不遠,台灣今年是否步入南韓後塵、出口轉為逆差?財經學者昨天表示,由於國際油價維持低檔、新台幣也沒有重貶,預估今年我國仍可維持貿易順差、即出口仍大於進口。

      南韓知識經濟部二日公布該國去年十二月出口狀況,出口總貨運量較前年同期下滑十七.四%,十一月份的跌幅為十九%,為八年來首見。

      此外,二○○八年韓國出現十一年來的首度貿易赤字,達一百三十億美元,由於全球需求急凍,去年出口僅成長十三.七%,進口總額則大增廿二%,至四千三百五十四億美元。

      去年十二月呈現出口大於進口的順差,主要是國際油價崩盤導致進口額下滑。南韓知識經濟部預估,二○○九年應該將會呈現一百一十九億美元的貿易順差。

      南韓宣布成立緊急機制

      南韓總統李明博昨日在青瓦台發表新年國情咨文時,宣布成立緊急經濟政府機制。李明博表示,上半年度的政府預算中,六十%是用來擴大需求,他指出:「專家預測今年下半年經濟將開始好轉,政府會盡一切可能讓這個預言成真。」

      他同時表示,將儘速成立直屬總統的綠色發展委員會,加強培植綠色產業,提升南韓的高科技與高附加價值的競爭優勢。

      但因為始終無法化解與反對黨之間的歧見,南韓執政黨大國黨(GNP)仍未能讓與美國所簽訂自由貿易協定,以及振興南韓經濟等諸多改革法案,送交國會表決。

      相較於南韓,台灣去年一至十一月貿易順差累積為一二九.四億美元。

      台灣經濟研究院六所所長楊家彥表示,南韓出現貿易逆差是在預期當中,這是因為全球貿易大幅萎縮,南韓出口數字首當其衝,再加上韓元匯率重貶,使得南韓進口成本大幅增加,因而出現貿易逆差。

      反觀台灣,楊家彥認為,今年上半年,預估我國出口力道勢必面臨嚴峻挑戰,但在國內景氣不好的情況下,進口也將同步大幅萎縮,加上央行的策略是維持新台幣匯率「緩貶」,應該仍會維持貿易順差。
