Work by the agency includes the corporate identity for GTV and its three channels, GT Prime, G Sports 1 and G Sports 2.
For each of the channels, four idents have also been created, based on the idea of rhythm and the theme of each channel.
The idents for the entertainment focused G Prime, for example, feature "a rich colour palette of oranges and golds that sparkle and explode onto the screen", according to Dunning Eley Jones.
Meanwhile, idents for the sports channel involve arcs, which represent speed and "impact".
Brian Eley, the design agency's creative director, said: "Once the name GTV had been agreed we designed a logo incorporating the letter G within an orange disc to represent the African sun, a simple, flexible device with lots of potential for animation that's abstract yet engaging."
Julian McIntyre, president of GTV owner Gateway Communications, said that the image will: "Appeal to a new breed of TV viewer."
Gateway Communications provides communications and telecommunications services across Africa.
