Internet Protocol Set Top Box - IP STB Internet Protocol Set Top Box - IP STB
An IP Set Top box is an electronic device that adapts IP television data into a format that is accessible by the end user. The output of an IP set top box can be a television RF channel (e.g. channel 3), video and audio signals or digital video signals. IP set top boxes are commonly located in a customer's home to allow the reception of IP video signals on a television or computer.

This figure shows a functional block diagram of an IP STB. This diagram shows that an IP STB typically receives IP packets that are encapsulated in Ethernet packets. The IP STB extracts the IP packets to obtain the transport stream (TS). The channel decoder detects and corrects errors and provides the transport stream to the descrambler assembly. The descrambler assembly receives key information from either a smart card or from an external conditional access system (e.g. via a return channel). Using the key(s), the STB can decode the transport stream and the program selector can extract the specific program stream that the user has selected. The IP STB then demultiplexes the transport stream to obtain the program information. The program table allows the IP STB to know which streams are for video, audio and other media for that program. The program stream is then divided into its elementary streams (voice, audio and control) which is supplied to a compositor that create the video signal that the television can display.
