Digital TV is coming

Yes­ter­day, the Hon­olulu Adver­tiser pub­lished an arti­cle about dig­i­tal TV con­ver­sion. On 17 Feb­ru­ary 2009, US tele­vi­sion sta­tions will stop broad­cast­ing ana­log tele­vi­sion sig­nals. On that date, any­one in the US who uses an antenna to receive their tele­vi­sion sig­nal on their ana­log tele­vi­sion will need a dig­i­tal con­verter box to receive broad­cast sig­nals. Cable and satel­lite sub­scribers have or will get con­verter boxes as part of their ser­vice agree­ment. All tele­vi­sions man­u­fac­tured for sale in the US after 1 March 2007 are required to have a dig­i­tal tuner, so these mod­els don’t need a con­verter box. The AP has an arti­cle with addi­tional details.

I’ve dis­cussed the FCC’s 700 mHz auc­tion on 18 March 2008 and 30 Jan­u­ary 2008. When the ana­log tele­vi­sion chan­nels are aban­doned, AT&T, Ver­i­zon and other com­pa­nies will use those fre­quen­cies for mobile phone and data services.

The US Depart­ment of Com­merce has a web site with infor­ma­tion on the DTV con­ver­sion, as does the FCC. Gov­ern­ment reg­u­la­tors and con­sumer activists fear that cable and satel­lite com­pa­nies will use dig­i­tal tele­vi­sion to scare up new sub­scribers. Another AP arti­cle states that His­pan­ics are the eth­nic group most likely to lose tele­vi­sion ser­vice after the con­ver­sion, even as the Fed­eral gov­ern­ment gives away sev­eral mil­lion coupons for dig­i­tal con­verter boxes. Hawaii has a diverse pop­u­la­tion, and get­ting the mes­sage out in mul­ti­ple lan­guages will be chal­leng­ing. I expect to see more arti­cles in the local papers, espe­cially in early 2009, even though the Adver­tiser claims that only 5.5% of the state’s tele­vi­sion view­ers rely on broad­cast signals.

Dig­i­tal TV con­verter boxes won’t turn an old ana­log set into a higher-definition TV, of course. These boxes have a dig­i­tal TV tuner that passes its out­put to an ana­log TV on chan­nel 3 or 4, like a video game con­sole would do.

Yahoo reports that broad­cast­ers will be required to run pub­lic ser­vice adver­tis­ing, in an effort to notify view­ers well before the cutover. The coupon request page uses reCAPTCHA – the same sys­tem I use to screen out spam com­ments on this blog.
