Emap Performance said it has focused on the "brand essence" of both channels in the redesign, which was handled in-house.
The identity of The Box, Emap's request-driven music channel, has moved away from computerised graphics to warmer, more personality-driven images. These will feature environments that viewers are likely to visit, such as cafes, shops, nightclub queues and restaurants, with the strapline "Ahead of the game".
Smash Hits TV now features neon-style graphics with new themed strands and zones throughout the day, based around the strapline "Face 2 face with the stars".
Nikki Causer, head of marketing for pop at Emap Performance, said: "The Box is famous for playing tracks before they become established hits and its new identity focuses on this fact. It's slick and modern and will help differentiate the channel in the marketplace. Smash Hits is known as the gateway into the world of pop and chart music. It lets people see the stars in different and exciting ways: the channel's new look plays on this."
Emap confirmed that The Box will launch its first advertising campaign this year. No further details were available.
