As of today, Triangle area Time Warner Cable digital cable customers should notice some changes when they sit down to watch their favorite shows -- an upgraded on-screen viewing guide.

The upgrade took place automatically overnight last night.

Time Warner Cable says the upgrade will make it easier for customers to search for On Demand content or use digital TV features like Start Over, which lets you start a program over at the beginning, and Look Back, which lets you go back three days to watch a program you missed but didn't record.

Other upgrades: The "A" button on the remote now brings up "Find Channels," which lets you find channels by category (sports, news, movies, etc); the "B" button still calls up the search function, but TWC says the search screen is now more intuitive.

Your TV now interrupts your regularly scheduled broadcast with a news flash: who's calling you on the phone.

AT&T is introducing a caller ID feature for its U-verse service, a competitor to cable television. When a call comes in, the feature pops a msg on the TV screen, showing viewers who's calling and the caller's phone number.

The feature was activated today for U-verse customers in Raleigh and Chapel Hill. U-verse customers in Charlotte got the caller ID feature last month.
