Comcast's California Region said it has completed a migration, begun last summer, to a full digital delivery system in a region anchored by Sacramento.

According to a recent third-quarter earnings report, Comcast is finished with its all-digital conversion initiative, which is known internally as "Project Cavalry."

The company immediately used the reclaimed bandwidth in California to launch 20 additional television networks – 18 in HD and two in SD – on its Xfinity TV. More than 30 communities in Comcast's Capital Region now have access to the new programming.

The conversion of Limited Basic channels from analog to digital also enables the delivery of faster Internet speeds, more channels and more Xfinity on-demand content, Comcast said.

The new HD channels include: BBC America HD, Bloomberg HD, CBS Sports HD, Fox Soccer HD, Galavision HD, Game Show Network HD, Gospel Music Channel HD, History International HD, Investigation Discovery HD, National Geographic Wild HD, NBA TV HD, NHL Network HD, Outdoor Channel HD, Oxygen HD, Sprout HD, Telemundo KCSO HD, The Hub HD and The Movie Channel (TMC) HD.

Customers who do not receive HD channels will have new programming options, as well.

As for the two standard-definition networks that are launching: Daystar, a faith-based Christian television network, will launch on Channel 234, and ReelzChannel, a network devoted to delivering entertaining and informative programming that is all about movies, will launch on Channel 150, Comcast said.

The new programming is available to residential homes and businesses in the following cities: Sacramento, Antelope, Cameron Park, Camino, Carmichael, Citrus Heights, Cool, Davis, Diamond Springs, El Dorado, El Dorado Hills, Elk Grove, Elverta, Fair Oaks, Folsom, Galt, Georgetown, Gold River, Mather, McClellan, Natomas, North Highlands, Orangevale, Placerville, Pollock Pines, Rancho Cordova, Rescue, Roseville, Rio Linda, Shingle Springs and Wilton. Davis and Roseville were already carrying some of the HD networks.
