Second pact the network revealed this month.

Fresh on the heels of a distribution agreement with Tribune Broadcasting, the Tube Music Network is expanding its multicasting music video network further through a deal with Sinclair Broadcast Group. Sinclair either owns, operates or programs services to 58 stations in 36 markets, including Pittsburgh, St. Louis, Las Vegas and Nashville. It will begin broadcasting Tube programming this summer.

The Tube’s multicasting technology allows stations to broadcast multiple singles on the same digital channel, allowing for greater programming options and increased interactivity with viewers.
