Abstract: A method of intelligently degrading the quality of content, such as video clips and music, stored on a mobile device over time. The method takes into account the probability of a user watching each item of content and either encodes the content at a lower bit-rate, or under certain circumstances, restores the content to its original quality by side-loading the content from a network content store. The bit-rate at which the content is to be encoded is linked to the probability of a piece of content being watched. If the probability of an item of content being watched is high, then the item is stored at a high bit-rate, and conversely, for low probabilities of watching, a low bit-rate is used. If required, in order to restore an item to a higher bit rate, the original high bit rate item can be requested from a network content store. The aim being to store as much content as possible in a given finite memory, but to ensure that content which is likely to be watched is not degraded.

Abstract: Data for presentation in real time, such as a video or audio sequence, is available on different encoded versions having different degrees Of compression. In order to assess, during transmission of one version, the feasibility of switching to another version, given the data rate known to be available at the time, a server computes, for a candidate version, in respect of at least one portion thereof that has not yet been sent, the maximum value of a timing error that would occur if any number of portions starting with that portion to be sent at the available rate. The selection of the same or a different version for continuing transmission is taken in dependence on a comparison between the computed error and the current state of a receiving buffer. Error values may be computed in advance for a range of transmitting rates, stored and later retrieved for use in estimating an error value corresponding to the actual transmitting rate.

Abstract translation: 用于实时呈现的数据，例如视频或音频序列，可在具有不同压缩程度的不同编码版本上使用。 为了在一个版本的传输期间评估切换到另一版本的可行性，考虑到当时已知可用的数据速率，服务器针对候选版本针对其候选版本至少有一部分来计算 尚未发送，如果以可用速率发送的部分开始的任何数量的部分将发生定时错误的最大值。 依赖于计算出的错误与接收缓冲器的当前状态之间的比较来进行用于连续传输的相同或不同版本的选择。 可以预先对存储并稍后检索的用于估计对应于实际传输速率的误差值的传输速率的范围来计算误差值。

Abstract: There is proposed a method of 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.

Abstract: Data to be transmitted over a network includes a first part (perhaps audio) which is always to be transmitted and alternative second parts (perhaps video coded at different compression rates) of which one is to be chosen for transmission, depending on the current network capacity. In order to accommodate systems where (owing perhaps to the use of a congestion control mechanism such as TCP) the capacity available is initially undetermined, one firstly begins to transmit just the first part. When the network capacity becomes known (typically by monitoring the performance of the network in transmitting the first part), one of the alternative second parts is chosen and transmission of it commences. If desired this may initially be preferentially to, or to the exclusion of, further transmission of the first part.

Abstract translation: 要通过网络发送的数据包括总是要发送的第一部分（可能是音频）和根据当前网络容量选择哪一个被选择用于传输的可选的第二部分（可能以不同的压缩率进行视频编码） 。 为了适应其中（由于可能使用TCP等拥塞控制机制）的系统，可用的容量最初未确定，首先开始仅传输第一部分。 当网络容量变得已知（通常通过监视网络在传输第一部分中的性能时），选择其中一个备选的第二部分并开始其传输。 如果需要，这可能最初优先地或不排除第一部分的进一步传输。

Abstract: A method of call control in which a first communications network, detecting calls directed to a destination in the first network; redirects at least some of the calls to a destination in a second network (e.g. on no answer from the destination in the first network). The first network then operates in two phases. In a first phase, for a group of calls redirected to the second network, the time delay before the call is answered in the second network is recorded. When a number of time delays have been recorded, a delay period is set to a value less than the maximum value of the recorded time delays. In a second phase, for a second group of calls redirected to the second network subsequent to the calls of the first group, when a call of the second group is not answered in the second network within the delay period, the call is redirected to a message service associated with the first network.

Abstract: A method of call control in which a first communications network, detecting calls directed to a destination in the first network; redirects at least some of the calls to a destination in a second network (e.g. on no answer from the destination in the first network). The first communications network obtains from a client on a terminal associated with the destination in the second network a value for the time delay before a call to the destination in the second network is redirected in the second network on no answer to an alternative destination and sets a delay period to a value less than the value of the time delay obtained from the client. When one of the plurality of calls redirected to the second network is not answered in the second network within the delay period, the first communications network redirects the call to an alternative destination associated with the first network.

Abstract: A preferred data provider is selected from a plurality of data providers by receiving a request for data from a client together with client identification data, identifying a plurality of data providers capable of providing data to the client, providing the client identification data to the data providers and instructing the data providers to perform tests in order to establish a measure of the elapsed time for a signal to be sent to and received from the client, and a measure indicative of their remaining capacity for data transfer, and to make these measures available to the system. One or more preferred data providers may then be selected on the basis of the elapsed time signals and the remaining capacity signals from the data providers.
