Abstract: A system for transmitting data via a core portion of a computer network to a mobile device is described. The network includes a plurality of access points wherein each access point includes a memory where data for onward transmission to the mobile device may be cached and is operable to communicate with the mobile device over a short-range wireless connection, when the mobile device is in range thereof, and with the core portion of the network over a backhaul connection on a substantially continuous basis. The exemplary system includes: a location collection server for receiving location data from the mobile device; an access point prediction engine for generating predictions of one or more of the access points which the mobile device is considered likely to come in range of in the future based on recent location data received at the location collection server; and a content delivery server for transmitting the data or a portion thereof to the one or more predicted access points via the backhaul connection for caching at the access points and for onward transmission to the mobile device in the event that the mobile device comes into range of the access point, or one or more of the access points where data is transmitted to more than one predicted access point.

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: A client on a packet based network is provided with a stream of encoded video data. The system is maximizes the bit-rate of the video stream by adapting to fluctuations in network capacity. Adaptation of the bit-rate of the transmitted enclosed video data is timed to occur upon a scene change in the video sequence. In this way the interruption to the viewer when the perceived quality of the video sequence increases or decreases is minimized as it is ‘hidden’ in the scene change. The technique may be applied to hierarchically encoded video data and to other encoding technique which adapt to network conditions.

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: Real-time data (e.g. video) is streamed over packet networks (e.g. the Internet). Streamed video is provided without the start-up delay by transmitting data from a video streamer to the video viewer more rapidly than the video viewer consumes the data and using the excess data to build a buffer at the video viewer. When a suitable sized buffer is built the transmission rate of data to the buffer may be reduced. In order to deliver the best quality material for the available bandwidth, the supply of video data may be switched to a higher bit-rate source when the reservoir is filled. Fluctuations in network throughput may be accommodated during the transmission of data on a fine scale by adjusting the transmission rate of the data and on a coarse scale by switching between data streams encoded at different bit-rates. Fluctuations in network throughput are determined by counting the number of missing packets at the video viewer which information may then be fed back to the video streamer to adjust the flow of data accordingly.

Abstract translation: 实时数据（例如视频）通过分组网络（例如因特网）流式传输。 通过从视频流传输数据到视频查看器，视频观看者消耗数据并使用多余的数据在视频观看器上构建缓冲区，从而提供流视频，而不需要启动延迟。 当构建适当大小的缓冲器时，可以减少到缓冲器的数据传输速率。 为了提供可用带宽的最佳质量材料，当储存器被填充时，可以将视频数据的供应切换到更高的比特率源。 通过在不同比特率编码的数据流之间进行切换，通过调整数据的传输速率和粗略尺度，可以在精细量级的数据传输期间适应网络吞吐量的波动。 网络吞吐量的波动通过对视频观看者丢失数据包的数量进行计数来确定，然后将该信息反馈给视频流，以相应地调整数据流。
