This digital transport adapter from Motorola is commonly installed on secondary television sets, such as those found in bedrooms, offices, or the kitchen to ensure reception of digital cable television channels without the size and expense of a traditional cable set top box.

Time Warner Cable has announced it will cease analog cable television service within five years, as the cable company embarks on a wholesale transition to all-digital cable.

The announcement came from CEO Glenn Britt during this morning’s investor conference call, and represents a major transition for the cable operator and its customers.

While Time Warner Cable already runs older digital cable systems in New York City and parts of Los Angeles, today’s announcement represents the company’s de-emphasis on Switched Digital Video (SDV), the technology the cable operator initially supported to free up channel space on its systems.  SDV allowed Time Warner Cable to maintain analog cable lineups for consumers who detest cable set top boxes.  Instead of converting the entire lineup to digital, Time Warner changed the way it delivered certain digital cable channels, only sending their signals to viewers in neighborhoods actually watching them at the time.

“We always said we would supplement switched digital video with going all-digital,” Britt said. “Our plan is to migrate all systems to all-digital over the next five years.”

The decision means Time Warner Cable has opted to follow Comcast’s lead towards all-digital systems, instead of trying to support both analog and digital video.

Britt said the company’s first target city for the all-digital switch is Augusta, Maine.  Customers there will be given the choice of taking the cable company’s traditional set top box or new Digital Transport Adapters (DTAs), devices which convert digital signals into standard definition analog video, suitable for televisions where customers may not need or want a full-powered cable box.  DTAs have traditionally been given away in small numbers or rented for a nominal fee (usually under $2 a month) by other cable operators like Comcast.  But Time Warner has not made any specific announcements about pricing for impacted subscribers just yet.

When complete, every Time Warner cable subscriber will need to have either a cable box, a DTA, or CableCARD for every cable-connected television in the home.

More than 300,000 residents from Louisville to Lexington in Kentucky and north into Indiana were left with no cable service for more than nine hours today after an equipment failure at an Insight Communications office on Okolona Road wiped out analog cable.

Louisville cable viewers channel flipping up and down the dial found nothing but frozen pictures, a captured moment in time from 2:53am this morning.  What they found next when calling Insight was nothing but hours of busy signals.  Some customers in southern Indiana found some channels worked fine while others did not.  In all, the outage impacted at least some channels across most of Insight’s service area in Kentuckiana.

Louisville, Kentucky

Insight initially blamed the problem on a router failure that developed during routine overnight maintenance.  A backup router also failed at the same time.  Company officials originally anticipated service would be restored by six this morning, but that did not come to pass.

Because the equipment failure had never been seen before by Insight technicians, it took nearly nine hours to finally resolve the problem.  Local television stations were deluged with calls from viewers wondering what happened to their favorite shows, and Insight’s dropped ball was topic number one on most local talk radio programs today.

Insight subscribers were especially upset that they couldn’t reach the cable company for answers.  Customer service lines were left jammed through much of the day.

Insight spokesman Jason Keller apologized for the outage.

Subscribers either saw this message, or a frozen picture across their channel lineup this morning.

“Everything that we have has a redundancy built into it. This is no different, but unfortunately on this particular morning with this particular piece of equipment, both the main equipment and the backup did not function properly,” Keller said, calling the outage “highly unusual.”

Keller called today’s outage the largest that he has seen during the company’s 10 years of service in Louisville.

By 10:00am, Louisville customers had their HD channels back, with the remaining analog channels restored by 1:30 this afternoon.

Despite the severity of the outage and its widespread impact, Insight Communications is refusing to issue blanket refunds to affected customers.  Instead, individual customers have to call or contact the company and request a refund, which they characterize as an amount under $1.00.

Customers can cost Insight more than that just by availing themselves of that option, and registering their displeasure over today’s long-lasting outage.

Impacted customers can request a refund online or by phone at (502) 357-4400.

Most television newscasts in the Louisville area treated today’s outage as their top news story, with several issuing periodic updates throughout the morning into the afternoon about the service problems.

Cincinnati residents relying on Time Warner analog cable are finding four fewer channels on their lineup since last August — two of which have been dropped this month.  Residents with digital-ready televisions will find many more missing, albeit temporarily, as of tomorrow.

Time Warner Cable in Cincinnati is moving channels around, including shifting former analog channels to digital and repositioning others in an effort to create additional space for new HD networks on the local cable system.

John Kiesewetter, the Cincinnati Enquirer‘s media blogger noticed the disappearing act last summer when two regional PBS stations — WPTD-TV Dayton and WCVN-TV Covington, Kentucky were dropped from the analog lineup.

This month, two more channels joined those PBS stations on the digital cable tier — Great American Country and Style.

Kiesewetter notes expanded basic customers’ bills remained the same, despite the loss of four channels from their lineup.  Company officials said customers can continue to watch all four channels by upgrading to digital cable for an additional fee, a prospect that bothers Kiesewetter:

Not everyone wants/can afford digital cable, despite all the TWC ads about bundling and locking in rates. The bottom line is if you’re a country music fan, you’ll have to pay more (getting digital cable) to see GAC.

Kiesewetter

“We realize this is unfortunate for GAC fans, but Time Warner Cable has decided to move GAC to Channel 255 to make  room for additional services,” Scott Durand, vice president, marketing for GAC told Kiesewetter. “Fans with only the expanded basic level of service will need to contact Time Warner  Cable to upgrade to digital in order to continue viewing GAC, the country music network that actually plays music.”

In fact, Time Warner Cable is dropping analog channels to make room for additional HD networks, which are digitally compressed and can be delivered in greater numbers than their analog counterparts.  Comcast customers across the country are also familiar with the erosion of analog cable channels in favor of digital for precisely the same reason — freeing up additional space.

But the result is almost always no reduction in rates for analog-only subscribers, despite the shrinking number of channels.

Cincinnati residents with cable-ready digital televisions may find an even smaller lineup waiting for them tomorrow morning.  That’s because Time Warner is shifting most of the local channels to new channel positions, again to make room for new HD networks.  Those with older sets or who use a Time Warner cable box will not notice anything, but those with HD, digital ready sets will need to rescan their channels to allow the TV to map their new channel positions.

City by city, Comcast is continuing its quest to make the switch to digital cable for an increasing portion of  its cable programming lineup.  Although the majority of subscribers will encounter letters from Comcast switching only a portion of the analog cable lineup, it’s a safe bet Comcast is looking to an all-digital future sooner or later.

Coming less than a year after the switch to digital broadcast television, the march to digital cable is causing confusion for subscribers who don’t understand the difference.

Analog cable television has been around for more than 20 years in most American cities.  It’s the kind of cable television that doesn’t usually need a converter box on top of the TV.  Just plug the cable line into the back of your television set, let the TV find and map available channels, and you can use your standard TV remote to enjoy basic or enhanced basic cable television.  Of course, if you subscribe to premium channels like HBO or Showtime, a box is required to descramble the encrypted signal.

Cable operators began launching “digital cable” in the 1990s, expanding the lineup of programming with hundreds of new channels that are compressed into a digital format, with a half dozen or more digital channels fitting in the same space used by just one analog channel.  Space on the cable line is getting increasingly crowded as cable systems launch new HD channels, support telephone service, and expand broadband service and speeds.

To make room, several of those old school analog channels have to go… digital.  If you already have a set top cable box — you probably won’t even notice the changeover.  But if you don’t have one of those boxes in your home, and your television doesn’t support CableCARD technology, Comcast has some bad news for you.  Sooner or later, you’ll either have to get a set top box or lose an increasing number of channels on your cable dial.

Comcast's digital adapter doesn't support HD channels

Comcast’s digital cable expansion is their solution to the traffic jam on their cable lines.  Some other cable companies take a different approach.  Knowing that many customers hate cable boxes, they’ve left analog channels alone, instead transmitting digital channels only to those homes actually watching them.  If nobody in your neighborhood is watching Current or Fox Business News, why waste the space to send those signals down the line to… nobody.  Time Warner Cable doesn’t for many of their digital channels.  If one lives in an eclectic viewing neighborhood, there are problems with this approach.  Potentially, if enough homes want to watch these lesser-viewed networks, and Time Warner runs out of the space it sets aside to carry a certain number of these channels, the subscriber will see a video busy signal — a message stating the channel is temporarily not available, at least until someone nearby changes channels, making room for the network you want to watch.

Comcast's digital solution is a problem for those who hate "the box" for weaving a rat's nest of cables behind one's television.

In most communities, Comcast will provide up to three digital adapter boxes at no charge, if you install them yourself on each television in your home.  Additional boxes are usually $1.99 per month.  That’s fine if you are still using an older television set and don’t care about HDTV programming — the digital adapters Comcast provides don’t support HD.  If you do want HD channels, you’ll need Comcast’s traditional converter box, which runs about $7 a month per television, or a CableCARD, if your television supports it.  Comcast also has elaborate instructions for customers with multiple TV inputs to support both standard and high definition signals, some through the digital adapter, others not, but it requires a lot of cables.

Customers who loathe boxes and don’t want to pay for them are upset by all of the changes, and either must cope with the new box, or gradually lose more and more analog channels as the conversion continues.  Broadcast basic customers getting only local channels from Comcast are unaffected by all of this, at least for now.  Owners of modern HD television sets aren’t impressed either — their sets, capable of receiving QAM digital cable channels without a box are no help because Comcast encrypts its digital cable lineup in many areas.

But the company still thinks of the project as a service upgrade for its customers, even dubbing it Project Cavalry on their company blog. When one customer wondered why the new equipment wasn’t available in his area yet, a company blogger responded, “We will not be “cherry picking” … all our systems will get the benefits. The Comcast Cavalry just hasn’t swept through your area yet, stay tuned.”

When asked why the devices don’t support HD channels, the response:

The DTA was designed as a low-end, basic device to do one thing and one thing only … convert digital signals back to analog for display on an analog TV. That’s all, no higher end outputs, no VOD, no HD, no interactive guide. Keeping the device simple as described is what kept the price down enough that we can provide so much free equipment to our customers. Also, the RF output makes it compatible with the absolute maximum number of TVs, which is critical to the program. As a digital device, however, it does offer dramatically-improved picture quality over analog even through the RF output.
