Comcast's digital switch - the one that's requiring expanded basic subscribers to put converter boxes on every TV - is proceeding on schedule, spokesman Steve Kipp said today.

The switch is largely done in Washington and now moving into remaining pockets within Seattle. Conversion began today in West Seattle and Georgetown. The rest of Seattle will begin seeing the changes by the end of the week.

Comcast is moving channels 30 to 70 from analog to digital, a move that's freeing up bandwidth that will be used for additional services. The company's also providing 33 new channels to affected subscribers, although most are high-definition versions of current channels.

It's converting 30-70 to digital in blocks of 20 channels at a time, with the first 20 moving in Seattle this week and the rest going on Nov. 10 and 12. This is the same schedule that was first disclosed in June.

Channels for "limited basic" customers will continue to broadcast in both digital and analog format, Kipp said.

More than 1.3 million boxes have been issued or 95 percent of the total needed to finish the project, he said. The whole state should be done by the end of the year.
