Now Hear This

An open and frank discussion of media and telecommunications issues - from the consumer point of view.

For months now we have been hearing from readers asking when the technical gurus over at our sister organization Consumer Reports would be providing ratings and reviews on digital TV converter boxes.


We are happy to announce that the wait is over and, in even happier news, it looks like some of the cheaper DTV converter boxes now on the market work just as well – or even better – than more expensive models.


Currently, there are only about 25 models of digital converter boxes available, all of which cost more than $50. Consumers can apply for two $40 government coupons towards the purchase of these devices.


The 14 models Consumer Reports tested are available for purchase either online or at stores including Wal-Mart, Best Buy, Circuit City, and Radio Shack and have been approved for the government’s converter box coupon program.


But there is a very big problem – those coupons expire 90 days after they are issued. Since the government began issuing the coupons in March, many have already expired, despite the fact that there is still only a limited number of models and units available to consumers. Many more coupons will expire soon.


CU policy analyst Joel Kelsey sums up the situation well.


“This is a consumer Catch-22,” says Kelsey. “Those who acted early in requesting coupons face limited or expensive choices in converter boxes, but can’t wait for more options because their coupons are expiring.”


Consumers who do not have a digital TV and currently rely on over-the-air-broadcasts for news and entertainment will have to purchase a digital converter box in order to receive digital signals from U.S. television stations.


CR's recommendations, ratings and shopping tips


CR found there were differences in performance among the 14 models tested, though not dramatic, with price not necessarily an indicator of quality. In fact, some of the less expensive models offered better picture quality than higher-priced models.


For those considering a DTV converter, CR advises first choosing models with better picture quality, and then narrowing choices down to those that have desired features. The Tivax STB-T9, $50, was among those with the best picture quality. The Microgem MG200, $65, also stood out in CR tests for its picture quality.


When judging picture quality at home, however, consumers should also consider other variables that can affect picture quality – the quality of the video transmitted by stations and the quality of the television set, either of which can often be the weak link in the picture quality chain.


Another characteristic to consider is tuner sensitivity, the ability to receive channels when signal strength is weak. CR found that the tuners in all boxes performed comparably in tests of their ability to pull in digital stations.


The tests were conducted at CR’s headquarters in Yonkers, NY using a standard residential rooftop antenna. Though the results are a rough indicator, it suggests that any of these boxes should be able to detect a similar number of channels. However, reception can vary for each user, depending on location, local terrain, signal strength, and the type of antenna being used, as well as the number of stations broadcast in the area and their signal strength.


CR recommends choosing a digital converter box that allows for individual channels to be easily added. This feature eliminates the need for consumers to perform the more time consuming “scan-for-all-channels.”


Additionally, if no signal is found on a particular channel, some boxes have on-screen signal meters that allow viewers to monitor signal strength while optimizing the antenna position. Signal strength meters are available on all boxes but are typically active only on channels that have already been found.


Also consider the electronic programming guide. These guides range from very basic to more comprehensive.


Analog-pass-through will allow the TV to continue receiving available analog, as well as digital, signals, including those from lower-power TV stations, which may continue to broadcast in analog after the February 2009 deadline.


One final note: Unlike the boxes themselves, CR’s ratings and recommendations on the DTV converters are available free-of-charge online.
