CEA-2007 Designed to Improve the Ability of Home Ethernet Networks to Play High Quality Audio and Video
Arlington, Va., December 2, 2003 - The Consumer Electronics Association (CEA) announced today that its Home Network Committee (R7) has adopted a new standard for home networks, designated CEA -2007 -Quality of Service Priority Groupings for 802.1Q. The standard was created to improve the ability of home Ethernet networks to play high -quality audio and video by defining a method for using 802.1q priorities for consumer electronic devices.
CEA -2007 recognizes three classes of quality of service (QoS): best effort, priority routing and fully managed connections. The standard sets aside several of the higher priorities on an Ethernet network that supports prioritization for use by parameterized services, while defining how the remaining priorities should be used for applications such as low latency video and audio.
"CEA -2007 allows simple QoS implementations, which are important for uninterrupted enjoyment of AV content, (i.e. movies and music), to be deployed now," said Glen Stone, director of strategy, standards and architecture, Sony Corp. and chairman of the working group that developed the standard. "The standard allows for more robust QoS implementations when they are developed in the future and maintains backward, and forward, compatibility with the earlier QoS implementations," he added.
"This standard sets the stage for consumer home networks that can play entertainment streams better, especially down the road as we start connecting different network types together and a movie or song could be coming from outside the home network," said Virginia Williams, director of engineering for CEA. "By giving manufacturers a new way to code their entertainment streams on Ethernet, CEA -2007 will enable home networks to better differentiate between content types and play them at the same high quality level as the sources are putting them out."
CEA -2007 arose from work being done in CEA's R7.5 working group one (WG1), which is defining an adapter standard for connecting an Ethernet network to a 1394 cluster network. Such an adapter must be able to map the parametric QoS mechanisms (i.e. bandwidth reservation) used by 1394 networks to the priorities used by Ethernet networks. As a result of the recognition of this need to map QoS services, WG1 members decided to initiate work on CEA -2007.
