摘要： PROBLEM TO BE SOLVED: To reduce power consumption, to reduce a peak and/or average power level and/or to reduce adjacent channel interference by adjusting transmit power of a communication device to control a transmit power level. SOLUTION: Requirements of a wireless communication between a wireless communication device and a receiving wireless communication device are determined (step 70), and whether a current transmit power level of the wireless communication can be lowered without adjusting the requirements of the wireless communication is determined (step 72). When the current transmit power level of the wireless communication can be lowered without adjusting the requirements of the wireless communication, the current transmit power level is adjusted to a second transmit power level (step 74), wherein the second transmit power level is less than the current transmit power level.

摘要： PROBLEM TO BE SOLVED: To provide a system and a method for simultaneous transmission of multiple media streams in a fixed bandwidth network. SOLUTION: The system is comprised of a central gateway media server and a plurality of client receiver units. The input media streams arrive from an external source and are then transmitted in a compressed format. The media server detects if the network bandwidth is close to saturation. The potential bandwidth saturation is measured by matching a time of the start of unit of media for each stream against the estimated transmission time for that unit. When any one actual transmission time exceeds its estimated transmission time by a predetermined threshold value, the network is deemed to be close to saturation, or already saturated, and at least one stream is selected for lowering the bandwidth. Thus, the amount of data to be transmitted is reduced using a compression technique or the like, which results in a lower data transmission rate and avoidance of saturation.

摘要翻译：要解决的问题：提供一种在固定带宽网络中同时传输多个媒体流的系统和方法。解决方案：该系统由中央网关媒体服务器和多个客户机接收器单元组成。输入媒体流从外部源到达，然后以压缩格式传输。媒体服务器检测网络带宽是否接近饱和。通过将每个流的媒体单元的开始时间与该单元的估计传输时间相匹配来测量潜在的带宽饱和度。当任何一个实际传输时间超过其估计传输时间预定阈值时，网络被认为接近饱和或已经饱和，并且选择至少一个流以降低带宽。因此，使用压缩技术等来减少要发送的数据量，这导致较低的数据传输速率和避免饱和。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To perform data processing corresponding to a multimedia program type.
SOLUTION: The upper limit of a peak bit rate and/or the upper limit of an average bit rate is determined based on a multimedia program type. As a case of processing, it can be adjusted based on remaining storage capacity. Multimedia data are then translated to produce translated multimedia data having a peak bit rate that does not exceed the selected upper limit of the peak bit rate and/or having an average bit rate that does not exceed the selected upper limit of the average bit rate. The translating of the multimedia can use rule sets based on content characteristics. After translating, the multimedia data can be transmitted via a network to a destination multimedia device or stored locally for subsequent use, or the transmission and the storage can be performed in combination.
