摘要： Interworking of a wireless telephony network (12) with a wireless Local Area Network (10) serving at least one mobile terminal user (14) is accomplished by reserving a General Packet Radio Service (GPRS) communications channel (20) of the wireless telephony network. Control communications signals received in the WLAN (10) from the mobile terminal user are communicated across the GPRS channel (20) to the wireless telephone network (12) and likewise, control communications signals from the wireless telephony network pass to the WLAN over the channel. Using the GPRS channel to carry control communications signals between the WLAN (10) and the WLAN (12) affords the advantage of a loose coupling without the risk of sending sensitive control information over a non-secure link.

摘要： The present invention concerns an adaptive streaming method, at a client device, for receiving content split into chunks corresponding to a content duration, the chunks being encoded at a server into at least a first and a second formats, the first format corresponding to a better content rendering quality level than the second format, a chunk being received during a chunk reception period. According to the invention, the method comprises the steps of measuring the available bandwidth between the client and the server for the next chunk reception period, requesting the server to send a chunk encoded at a format so that the chunk can be received during the next chunk reception period, and if some bandwidth is available for the next chunk reception period, requesting the server to send a part of a chunk encoded at a second format, the chunk having been received encoded at the first format.

摘要： A method of streaming an output content stream transcoded from a corresponding input content stream includes offering, to a client device, a number of alternative versions of the output content stream, for selection by the client device, and dividing the input content stream into two or more segments. The segments can have two or more different lengths. Prior to the offering step at least a first segment of the input content stream is transcoded into corresponding segments of an output content stream representing alternative versions offered to the client device. Upon receiving a request from the client device for a selected version of the output content stream, streaming is begun with using a first one of the corresponding segments of an output content stream representing alternative versions offered to the client device that had been transcoded and stored prior to offering. Information is extracted from subsequent requests indicating a capacity of a connection with the client. Depending on whether or not the connection capacity varies over a predetermined number of consecutive requests, the streamed segments are of the shorter or longer type.
