摘要： A video sequence (4) is subjected to a signal compression process, in which the video sequence is divided (14) into a plurality of segments such that in each segment the number of bits required to code each frame in uncompressed form falls within a range having a predetermined magnitude, and a quantisation level is selected (17) for the encoding (19) of each segment such that the overall bit rate of the segment corresponds to a predetermined value. This value may be pre-set, or may be set in response to an input from the transmission network (3) or remote decoder (2). The quantisation level Q is determined according to a function of the number of bits per frame R, determined by analysis (10,11,12,13) of the entire sequence prior to transmission.

摘要： A video stream is digitally encoded such that the rate at which individual segments of data are encoded varies according to the amount of data required to generate each segment. Frames are selectively omitted from transmission (32) such that the cumulative frame rate does not fall below a predetermined value. This process can be used to ensure that the next frame to be displayed is always available in the buffer store 6 associated with the decoder (2). The decoder (2) is arranged to identify where frames have been omitted from the decoded transmission, and to perform a resynchronisation (7) on the decoded stream by comparison between time stamps in the video stream and a corresponding audio stream. Resynchronisation may be performed by extending the durations of individual frames, or by repeating frames.
摘要翻译： 视频流被数字编码，使得数据的各个段被编码的速率根据产生每个段所需的数据量而变化。 从传输（32）中选择性地省略帧，使得累积帧速率不降低到预定值以下。 该过程可以用于确保在与解码器（2）相关联的缓冲存储器6中将要显示的下一帧总是可用。 解码器（2）被布置为识别从解码的传输中哪里已经被省略的位置，并且通过在视频流中的时间戳与相应的音频流之间的比较来对解码的流执行再同步（7）。 可以通过扩展单个帧的持续时间或重复帧来执行重新同步。

摘要： Faults resulting in reception of a still, but unknown, frame are recognised by comparing each received frame of the video signal with its predecessor, incrementing a counter in the event that the difference between the frames falls below a threshold; and generating an alarm signal in the event that the count of the counter exceeds a predetermined count. Other types of fault such as loss of signal (i.e. reception of just noise) are recognised by incrementing the counter whenever the difference exceeds a threshold. Similar results may be obtained by instead the monitoring quantisation step size and/or number of transmitted bits of a digitally coded signal, and noting that it falls below, or exceeds, a threshold. A preferred option is to compute a complexity measure, being a monotonically increasing function (e.g the product) of the quantisation step size and of the number of coded bits and compare this with the threshold value. Faults occasioned by receipt of a particular fixed image instead of the wanted picture are recognised by comparing each frame of the video signal with the fixed image, and generating an alarm signal in the event that the difference between the frames consistently falls below a threshold.
摘要翻译： 通过将视频信号的每个接收帧与其前身进行比较来识别导致仍然但未知的帧的接收的故障，在帧之间的差异低于阈值的情况下增加计数器; 并且在计数器的计数超过预定计数的情况下产生报警信号。 当差异超过阈值时，通过增加计数器来识别其它类型的故障，例如信号的丢失（即仅接收噪声）。 可以通过监视数字编码信号的发送位的量化步长和/或数量，并注意到其下降或超过阈值来获得类似的结果。 优选的选择是计算复杂性度量，其是量化步长和编码比特数的单调递增函数（例如乘积），并将其与阈值进行比较。 通过将视频信号的每个帧与固定图像进行比较来识别通过接收到特定固定图像而不是所需图像而产生的故障，并且在帧之间的差异始终低于阈值的情况下产生报警信号。

摘要： The present invention relates to authenticating a mobile device using location information associated with the device. The present invention provides a mechanism for authenticating a mobile device based on location related information or a “logical location”, but without requiring an actual location. The mobile user device gathers tokens such as SIM data from other wireless devices using wireless communication between the user device and the other devices. A server determines whether these tokens match predetermined reference information, and if so authenticates the user device.

摘要： A method relates to side-loading content onto a mobile device, preferably using a WiFi connection, from a network content store and storing it on the device for viewing later. The method automatically determines when to delete stored content, and more importantly, what content should be transferred over the network in the first instance. The system comprises a content manager which takes into account various parameters to determine what should be transferred and, if required, what should be deleted from the device. The parameters used include user profiles, size of a potential download, as well as available storage space on the device and the predicted duration the device will be in range of a wireless hotspot or broadcast network.

摘要： A video sequence is to be transmitted at a selectable quality from a server over a network. A network control protocol operates in response to a control parameter to allocate to the server a share of available transmission capacity in proportion to the value of the control parameter. First, one determines a plurality of transmission rate values that are needed over successive time periods of the sequence for successful transmission of the sequence at a reference quality; then the control parameter is set, proportional to the transmission rate value and communicated to the control protocol at corresponding time instants. The sequences can then be transmitted, encoded at a quality from time to time selected in dependence upon the actual transmission capacity made available by the network to the server.
