describes the design and implementation of a P2P-based location-aware video streaming system.

The video streaming service has a capability of multi-resolution video streaming with hierarchical video encoding. The location management service provides a function to look up video images by locations. The video density management service provides a similar look-up function but by video image density. All those services are constructed on musasabi, a platform for highly reliable P2P services.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-02-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2011-IOT-12"}]},"relation_version_is_last":true,"weko_creator_id":"10"}}
