CTA 931-C (S2018)

This specification defines a standardized method for communication of certain basic operational functions between devices in a home network. The functions are those typically associated with a device’s front panel controls or remote commander. Functions associated with the operation of IR blaster arrangements are also accommodated by this method. Normative requirements are specified here for two distinct types of interfaces and their associated lower-layer protocols. One set is based on IEEE 1394 and A/VC commands and the other on devices supporting HTTP 1.1 over IP.
