This International Standard specifies the common communication protocol (CCP) layer that is
capable of providing interoperability and interconnectivity between heterogeneous network
technologies, as well as the basic data transmission scheme between devices linked to
heterogeneous networks through the CCP layer. The standard also specifies the packet
structure in the CCP layer and the common addressing scheme that can be understood
among heterogeneous devices. Furthermore, there are specifications regarding protocols
capable of providing diverse home network applications through the CCP layer such as the
home network management protocol (HNMP), universal home control protocol (UHCP), home
multimedia service protocol (HMSP) and home data service protocol (HDSP).
NOTE HNMP is the overall home network management protocol that detects or registers devices. UHCP controls
and monitors devices from remote locations. HMSP is the A/V protocol for home entertainment services. HDSP
deals with data and messaging services.
This standard is to be applied to systems with network capabilities and those that constitute
home networks such as electronic appliances, A/V components, control devices, network
terminals and home servers. Moreover, this standard is applicable to a home network
consisting of a single home server.
This International Standard gives
– a definition of the CCP layer,
– a data transmission scheme in the CCP layer,
– a CCP packet structure,
– a CCP addressing scheme,
– a home network management protocol (HNMP),
– a universal home control protocol (UHCP),
– a home data service protocol (HDSP),
– requirements of home multimedia service protocol (HMSP).
A home network provides interoperability and interconnectivity regardless of the appliance
manufacturer or the network type so that the user is able to receive desired services at any
point in time. However, current home network technologies have independent communication
protocol layer structures, as shown in Figure 1, with different addressing schemes, data
transmission schemes, data processing methods and data formats.
In order to solve problems associated with interoperability and interconnectivity among
heterogeneous network technologies, this standard aims to define the CCP layer as a type of
a convergence layer.
