Title:
ビデオストリーミングに対する電力認識適応
Document Type and Number:
Japanese Patent JP6890158
Kind Code:
B2
Abstract:
Power aware adaption for a power aware video streaming system may be used on the complexity information conveyed in different ways. A complexity level of a data stream, such as a video data stream, may be selected as a function of a remaining battery-power of a wireless transmit/receive unit (WTRU) and on a state set of a plurality of state sets may be stored and/or managed by the WTRU. These state sets may correspond to, for example, different content sources and/or different complexity estimation algorithms and may be used to select the complexity level of the data stream. The data stream may then be received at the selected complexity level. The complexity level and/or a bitrate of the data stream may be adapted to accommodate, for example, the remaining battery power and/or other circumstances. The adaption may be customized according to the objectives of use cases.
