While flipping through the channels, Bowling Green residents might notice some changes.

Insight Communications, the major cable provider for the area, has moved some channels and upgraded others to digital.

CNN has switched from channel 44 to channel 67 and CNN Headline News has moved from channel 65 to 68.

The company will switch more channels at the end of this month. C-SPAN will move from channel 22 to channel 98; a religious access program will move from 25 to 96; and an educational access program will move from channel 13 to 95.

“We are constantly adding new programming to our lineup, so there are times when we have to adjust placement of a channel in order for the new channel to be included,” said Jason Keller, public affairs director for Insight. “But there are also behind-the-scenes technical issues that necessitate moving a channel from one spot to another.”

Insight has added Shop NBC, Day Star and Jewelry TV to local lineups, and it recently cut the Game Show Network.

The cost for certain networks has skyrocketed, prompting Insight officials to study and cut some channels, such as GSN.

“To keep the size of these increases under control, we have to remove certain high-cost networks,” he said.

All basic cable customers are affected by the changes, Keller said.

The company, which serves 775,000 customers in Kentucky, Indiana and Ohio, recently started transmitting some channels digitally. The E! entertainment channel, the golf channel and Versus outdoor channel all went digital in January. Customers who buy the company’s digital plan and have a high-definition television are impacted, Keller said.

“The world and times in which we live are moving to an all-digital experience,” he said. “It truly provides a better picture and better sound quality.”

The changes will not impact customers’ cable bills, Keller said.

Other companies are making similar changes. Time Warner Cable recently announced it will change its digital lineup in March for some areas, and cable provider Comcast will drop about 50 analog channels in March to make room for digital channels, according to reports.

In the past year, several companies joined the digital movement. Local stations went digital last year after the Federal Communications Commission mandated that broadcasters switch from analog to digital transmitters.

At that time, some residents, mainly those with television antennas, worried they would not be able to get the digital signal.

Workers at WKYU-PBS in Bowling Green fielded a couple of dozen complaints over the past year from people who had trouble receiving a digital signal. Most concerns came from people in rural areas who need a more efficient antenna, said Jack Hanes, director of educational telecommunications at Western Kentucky University.

“That was a problem nationwide,” he said.

Similarly, Wilburn England, chief engineer at WBKO, said some viewers are unable to get the digital signal, but they need to improve their antennas.

Overall, the switch has been positive, they said.

“It’s just better video quality, better audio quality,” England said. With the analog signal, “if the signal got weak, it would get snowy. The digital signal will not do that.”
