摘要： Compressed recorded video is to be transmitted over a variable bit-rate link, using bandwidth reservation. In order to determining the transmission rate that is to be used (and reserved) at any given time, in such a way as to make the two match so as to minimize wasted bandwidth, the data stream is split into chunks chosen such that the average bit rate for the chunk as a whole is no less that the average bit rate for any shorter chunk starting at the same point. The chunk can then be transmitted using this average rate without any buffering problems. Preferably one chooses chunks so that the average bit rate for the chunk is no less than that for any shorter or longer chunk starting at the same point. This has the benefit that a request for bandwidth never has to ask for an allocation that is higher than that specified in any previous such request. In systems that switch between streams of different degrees compression. the switching points can with advantage be chosen to coincide with the inter-chunk boundaries.

摘要： A technique for operating a wireless communications system that supports multi-user multiple-input multiple-output (MU-MIMO) communications between a base station and multiple mobile stations involves generating inter-cell interference information at the mobile stations and providing the inter-cell interference information to the base station. The base station uses the inter-cell interference information to calculate channel quality indicators (CQIs) and then makes scheduling decisions in response to the CQIs. Data is transmitted from the base station to the mobile stations according to the scheduling decisions.

摘要： A method and a system for distributing key of media stream are provided. The method comprises: determining, by a security management server, whether a domain to which the calling terminal belongs and a domain to which a called terminal belongs subscribe a key distribution protocol; generating a key based on encryption capability information obtained in a calling process, and distributing the generated key to the calling terminal and the called terminal, if the protocol has been subscribed; generating a key based on encryption capability information obtained in a calling process, and distributing the generated key to the terminal at the same side as the security management server, if the protocol has not been subscribed. By applying the disclosure, the key is generated by the security management server, so that complexity may be reduced for media stream key negotiation to facilitate promotion of media stream encryption service.

摘要： A novel motion estimation algorithm, AMESSAD (adaptive motion estimation based on statistical sum of absolute difference) is provided. The algorithm adaptively determines motion search step size based on statistical distribution of SAD (sum of absolute difference). That is, search step sizes to estimate motion in one portion of a frame are calculated using SAD values from neighboring portions of the frame. The efficient search procedure improves the implementation of motion compensation and transform based hybrid video coders, such as the H.26P and MPEG-X standard video compression. Compared with fixed step-size motion estimation, the adaptive algorithm improves motion estimation and hence overall video encoding speed. In addition, improved visual quality can be achieved in many cases because the algorithm differentiates regions with motion activity and allocates more motion estimation resources to local areas or local frames with higher motion content.

摘要翻译： 提供了一种新颖的运动估计算法，AMESSAD（基于绝对差的统计和的自适应运动估计）。 该算法基于SAD的统计分布（绝对差的和）自适应地确定运动搜索步长。 也就是说，使用来自帧的相邻部分的SAD值来计算用于估计帧的一部分中的运动的搜索步长。 高效的搜索过程改进了运动补偿和基于变换的混合视频编码器的实现，如H.26P和MPEG-X标准视频压缩。 与固定步长运动估计相比，自适应算法改善了运动估计，从而改善了整体视频编码速度。 此外，在许多情况下可以实现改进的视觉质量，因为该算法将区域与运动活动区分开，并且将更多的运动估计资源分配给具有较高运动内容的局部区域或局部帧。

摘要： An optoelectronic device and a method of fabricating a photosensitive optoelectronic device includes depositing a first organic semiconductor material on a first electrode to form a continuous first layer; depositing a layer of a second organic semiconductor material on the first layer to form a discontinuous second layer, portions of the first layer remaining exposed; and depositing the first organic semiconductor material on the second layer to form a discontinuous third layer, portions of at least the second layer remaining exposed. The depositing of the first and second organic semiconductor materials are alternated a number of times until a final layer of the second organic material is added to form a continuous layer. A second electrode is deposited over this final layer. One of the first electrode and the second electrode is transparent, and the first organic semiconductor material is one or more donor-type materials or one or more acceptor-type materials relative to second organic semiconductor material, which is one or more materials of the other material type.

摘要： An optical fiber sensor (100) can be used to measure pressure with high sensitivity and fine resolution. As a (108) at the end of the sensor expands or contracts, the spectrum of a beam reflected from the end of fiber shifts, producing a change linked to pressure exerted on the sensor. Novel aspects of the present inventive sensor include the direct bonding of a silica thin film diaphragm (110) to the optical fiber with localized or confined heating and a uniform thickness of the diaphragm. The resulting sensor has a diameter that matches the diameter of the optical fiber. Because the sensor is all silica, it does not from temperature-induced error. In addition, the sensor can be very sensitive because the diaphragm can be very thin; it can also make highly repeatable measurements due to its very uniform thickness.
