Consumers own many different HDMI sources at home. They range from Blu-ray and STB through to cameras and even smartphones. Consequently, ever more inputs are required to the final display to allow simultaneous connection of several HDMI devices. An HDMI switch expands the single HDMI input of your TV or your STB, at low cost.
