Overview
IEC 62295:2007 - “Multimedia systems - Common communication protocol for inter-connectivity on heterogeneous networks” - defines a Common Communication Protocol (CCP) layer to enable interoperability and interconnectivity across different home and multimedia network technologies. The standard specifies CCP packet structure, a common addressing scheme, data delivery methods (unicast, multicast, broadcast) and a set of application-level protocols for home network services. The bilingual 2012-08 edition corresponds to the original English edition published in 2007.
Key topics and requirements
- CCP layer definition: placement of the CCP layer between application APIs and lower protocol layers to abstract diverse network links.
- Packet format and fields: CCP header, versioning, source/destination addressing, type fields, payload length and reserved fields.
- Addressing scheme: domain, cluster and device identifier structure to support traffic switching and routing across heterogeneous networks.
- Data delivery mechanisms: requirements for reliable unicast, multicast and broadcast delivery across mixed network types.
- Home server interface: functional requirements for device registration, discovery and management via the home server.
- Device requirements: registration, classification, alive-check and lifecycle management for CCP devices.
- Application protocols supported over CCP:
- Home Network Management Protocol (HNMP) - device and server registration, management commands.
- Universal Home Control Protocol (UHCP) - device control, queries and notifications.
- Home Multimedia Service Protocol (HMSP) - multimedia resource management and streaming controls.
- Home Data Service Protocol (HDSP) - file, directory and messaging services.
- Error codes, transaction handling and FSMs: behavioural state machines and transaction ID fields for reliable interactions.
Applications and users
IEC 62295 is targeted at organizations and engineers designing interoperable home multimedia and smart-home systems:
- Device manufacturers (set-top boxes, smart appliances, media servers) implementing a CCP-compatible stack.
- Firmware and chipset vendors building protocol stacks and CCP APIs.
- System integrators and software developers developing home server software, multimedia applications and device management platforms.
- Service providers and installers seeking standardized device interoperability for home deployments.
- Test labs and certification bodies validating conformance to CCP, HNMP, UHCP, HMSP and HDSP.
Benefits include simplified cross-vendor interoperability, a unified addressing model for mixed network environments, and standardized messaging for multimedia, control and data services.
