Title:
モバイルブロードキャストネットワークにおける更新検出のための適応監視方法
Document Type and Number:
Japanese Patent JP5529292
Kind Code:
B2
Abstract:
Information included within metadata broadcast within an overhead flow of a mobile broadcast network enables receiver devices to determine when metadata updates will occur. The mobile broadcast network can include within metadata messages information related to a time for the next metadata update. Using this information, receiver devices can determine when the next metadata update will occur and de-energize the receiver until that time. Enabling mobile devices to remain de-energized until the next metadata update improves their power efficiency. Synchronizing mobile devices to access the overhead flow for updated metadata reduces the content delivery latency that the system must accommodate, thereby improving system flexibility and bandwidth efficiency. Specify the time of a next metadata update enables the broadcast system to change the rate and timing at which metadata updates are performed.
