Beginning next month, the City of Somerville's governmental cable TV station will switch its broadcast to channel 22 for Comcast subscribers, the city said last week.
Programming will change over June 5.
The Federal Communications Commission, which oversees broadcast technology and policy, ordered the shift to accommodate an unrelated but legally required channel reshuffle.
The change will effect other access channels in the greater Boston TV market, said Tom Champion, city spokesman.
Customers of RCN will see no change to their channel lineup, Champion said.
