Set Top Box Certification Testing Laboratory

1. Introduction to set-top box certification products:

A set-top box refers to a digital video converter box. It is usually called a set-top box or set-top box, and is a device that connects a TV set to an external signal source. It can convert compressed digital signals into TV content and display it on the TV set. The signal can come from cable, satellite antenna, broadband network, and terrestrial broadcasting. Introduction to the functions of a digital video converter box: Interactive function The set-top box needs to provide two types of interactive functions: interactive content selection and interactive content control.
