Description
Summary:The goal of the cycle time synchronization and its specific implementation described in this article is to ensure a sufficient accuracy and fidelity of the streamed multimedia contents transmitted between networked IEEE 1394 clusters via UWB (ultra wide band) over coaxial cable in HANA (HIGh definition audio video network alliance) and AV/C (IEEE 1394 audio/video control protocol) consumer's home digital multimedia networks. The implementation of this synchronization mechanism, based on the standard "Networking IEEE 1394 Clusters via UWB over coaxial cable", solves two specific potential problems, which would arise without a proper synchronization method and which otherwise would damage the quality of streamed content enough to avoid the success of the HANA networks in its just and only target, the consumer electronics market. This mechanism avoids buffer under- and overruns in sink's clusters as well as prevents phase difference artifacts when transmitting streaming data through the consumer's home network.
