Belmont officials are asking residents to share their thoughts on the future of cable television service, technology and community media as part of the process for renewing Comcast’s franchise as the town’s service provider. There will be four gatherings this week for residents to learn about the renewal process, and to share opinions about services that Comcast could offer the town, and review how community groups like Belmont Media Center, schools, businesses, and local government are using media technology to disseminate information. On Tuesday, the Beech Street Center will host a focus group on local government from 2 p.m. to 4 p.m. , and a session for arts, cultural, and media organizations from 7 to 9 p.m. On Wednesday, the Belmont Gallery of Art, on the third floor of the Homer Municipal Building on Moore Street, will host a focus group covering the schools and educational issues from 3:30 to 5:30 p.m., and a discussion from 7 to 9 p.m. for community, nonprofit, civic, and faith-based groups. Participants in the focus groups will receive a free car wash at Belmont Car Wash, two tickets to the Studio Cinema, and a donut and coffee from Ohlin’s Bakery.
