I. Introduction to Set-top Box Certified Products

A set-top box refers to a digital video conversion box. It is usually called a set-top box or a set-top box, which is a device that connects a television to an external signal source. It can convert compressed digital signals into TV content and display it on the television. Signals can come from wired cables, satellite antennas, broadband networks and terrestrial broadcasting. The function introduction of the digital video conversion box: The interactive function set-top box needs to provide two types of interactive functions: interactive content selection and content interactive control.
