摘要： The present invention provides method and apparatus for designing modulation and coding set of communication System. The method for designing modulation and coding set designs a proper set of modulation and coding schemes (MCS), based on probability distribution of the quality of received signal in the communication system, so as to optimize the whole performance of the communication system. The method comprises the steps of: acquiring the probability distribution of the quality of the received signal in the communication system; performing a calculation on the target performance of the communication system based on the acquired probability distribution of the quality of the received signal and a plurality of MCSs, to design a proper set of MCSs for the communication system, so that a region where the probability of the quality of the received signal appears more frequently are provided with more levels of the MCSs.

摘要： A method to establish a full-duplex audio connection over an asynchronous Bluetooth link between an audio terminal and a wireless audio device exchanges supported service classes and codecs between the audio terminal and the wireless audio device, negotiates a service class and a codec that are common to the audio terminal and the wireless audio device, and establishes an asynchronous audio connection between the audio terminal and the wireless audio device using the common service class and the codec. The audio connection established can depend on the software application desiring the audio connection plus the available service classes and codecs at the audio terminal and wireless audio device. For non-internet protocol (non-IP) audio applications, an ACL using AVDTP may be selected; for IP audio applications, an ACL using BNEP may be selected. Both AVDTP and BNEP can use codecs that support wide bandwidth audio.

摘要： The ability to remove a watermark from an encoded image by reversible watermarking opens the possibility of various novel applications. Several such applications are detailed. One permits different classes of consumers to gain access to different versions of an image. A pristine image is intentionally degraded in some fashion, and distributed to consumers. By reference to one or more watermarks in the degraded image, some or all of the degradation can be removed, or transformed to a less-objectionable state. Through such arrangements, image consumers with different needs can gain access to versions of the image having differing qualities.

摘要： A method for realizing route discovery in a network includes: classifying a level of a node in the network; receiving a route request packet from a node adjacent to the node; comparing a node level indicated by node level information contained in the received route request packet with the level of the node; updating, in a case where the level of the node is higher than the node level indicated by the node level information contained in the route request packet, the node level indicated by the node level information contained in the route request packet to be the level of the node; and forwarding the updated route request packet to other nodes adjacent to the node.

摘要： The disclosure details methods of measuring the quality of service of received media signals by analyzing digital watermarks embedded in such signals. The quality of a received video or audio signal can thereby be assessed without having the original version of the signal before transmission. Instead, the strength or quality of the embedded digital watermark is analyzed to determine the quality of the received signal. The degradation of a watermark signal is used to assess quality of service of signals, such as audio and video. Several other features and arrangements are also detailed.
摘要翻译：本公开详细描述了通过分析嵌入在这些信号中的数字水印来测量接收的媒体信号的服务质量的方法。因此可以在传送前没有信号的原始版本来评估所接收的视频或音频信号的质量。相反，分析嵌入式数字水印的强度或质量来确定接收信号的质量。水印信号的劣化用于评估诸如音频和视频的信号的服务质量。还详细介绍了其他一些功能和安排。
