IEC 62514 pdf download Multimedia gateway in home networks – Guidelines
4.2.5 Security The HMG shall support DRM, key management, authentication and security to log on outside networks.
4.2.6 Interconnection HMG shall support the network management, protocol translation, address assignment, configuration and management on the home networked devices, in different multimedia networks.
4.2.7 Interfaces and access These provide the connection between the home network and outside networks (for example the Internet) when necessary, which is optional. The detailed interface and communication protocol requirements on both LAN side and WAN side are specified in Clause 11. The specific protocol that is to be applied depends on the application case.
5 Interconnection requirements
5.1 General connection requirements Where the home multimedia network is an IP network, the requirements for the HMG should be as follows: a) HMG shall implement a Dynamic Host Configuration Protocol (DHCP) server in order to assign IP address to DHCP client in the home network where the HMG is involved.
b) HMG should support Domain Name System (DNS) in order to use device name for better user experience.
c) Those messages are formatted by using the SOAP HTTP binding, which shall be compliant with ISO/IEC 29341-1.
d) HMG should collect information with respect to all the devices connected to the home network by using device description and service description of each device in order to manage the devices.
e) HMG also should control other devices such as HMRec and HMSou by using appropriate actions to realize use cases described in this standard. HMG shall also conform to the following requirements defined and specified in IEC 62481-1.
f) HMG shall support a TCP/IP stack that includes IPv4, TCP, UDP, ARP, and ICMP.
g) HMG may also support general capability recommendations and device recommendations.
h) The detailed methods of interconnection shall be compliant with 7.3 of IEC 62481-1:2007 (Device discovery and control).
i) HMG shall support Simple Object Access Protocol (SOAP) header and body elements, and the messages are delivered via HTTP. The HMG as well as HMSou and HMRec support the messaging scheme by using GENA protocol to exchange the event information inside the high-speed system. A control point invokes the action to the device’s service in order to control it and when the action has completed or failed, the service returns any results or errors of the action.
j) HMG shall support the detailed methods of device management.
