Definition of Complex Set. Top Box (CSTB) A Complex Set Top Box (CSTB) is a device equipped to allow conditional access or digital rights protection by descrambling using dynamically allocated keys, where the primary function of the device is the reception, descrambling and processing of data from digital broadcasting streams and related services including protecting the content in transport and on the platform. It may also include additional functions including audio and video decoding and output capability and/or the ability to provide content to one or more dedicated Thin-Client/Remote CSTBs via a home network, and/or gateway and routing functions. For the purposes of this Voluntary Agreement, a device shall not be considered to be a CSTB unless it fulfils the functions of a CSTB when activated by the Service Provider and is supplied to a Service Provider as defined in this Agreement. A Simple STB, as defined in Annex F, is outside the scope of this Voluntary Agreement. For avoidance of doubt, the use of fixed key descrambling or the inclusion of an HDMI interface and/or Xxxxxxx coding does not make a STB that would otherwise be classified as a Simple STB into a Complex STB. Also excluded from the scope of this Voluntary Agreement are devices whose primary function is something other than the reception of television signals, such as, but not limited to: • Computers fitted with digital TV tuners or TV add-in cards; • Games consoles with digital TV tuners • Digital receivers with recording function based on removable media in a standard library format (VHS tape, DVD, Blu-ray disc and similar) • Digital TVs with integrated receiver decoders • External plug in digital receivers for computers (e.g. USB) unless device could be powered from the AC mains.
