Abstract: An electronic device has a multimedia framework including an integration layer and a higher-level application layer. The integration layer includes predefined media processing components having an input/output interface configurable based on the type and format of media content delivered to the device during a streaming media session and that provide predefined media processing functions to the application layer for enabling playback of the media content. A streaming media management component included in the integration layer establishes and manages the streaming media session and configures one or more content pipes used during the streaming media session to access packets received by one or more sockets. The component also maps the content pipes to the sockets and processes packets retrieved from the one or more content pipes such that the media content is provided to corresponding ones of the predefined media processing components in accordance with their configured input/output interfaces.

Abstract: A streaming server sends a multimedia stream for delivery by a hybrid unicast-broadcast delivery network to a mobile terminal. To assist that mobile terminal change access delivery from unicast to broadcast, the streaming server sends multimedia content timing information that indicates one or more interstices in the content of the multimedia stream. The mobile terminal receives such multimedia content timing information upon receiving the multimedia stream by unicast. Although the mobile terminal determines the same multimedia stream is also available by broadcast, the mobile terminal initiates a change from unicast to broadcast during an interstice. Because the mobile terminal delays the access change until an interstice, any data loss resulting from the access change has a minimal effect on a subscriber's experience of the multimedia content. Moreover, regular occurrence of interstices ensures that such change will not be significantly delayed, and thus, neither will use of broadcast.

Abstract: The present invention provides for a cellular communications device comprising determining a most suitable cell based on a characteristic of signals received from a plurality of cells, the signals from each cell being provided over a band of frequencies, and the said determination comprising the steps of taking a series of measurements of the said characteristics for each frequency so as to obtain an average value, wherein each measurement in the said series is taken for all of the frequencies in the said band before the next measurement in the series is taken, and the said series of measurements on each frequency are equally spaced and serve to provide equal intervals therebetween for further processing of signals from network cells.

Abstract: A method of network acquisition for a cellular radio communications device arranged for operation in accordance with a plurality of radio technologies and comprising searching to identify a suitable cell on one radio technology. Subsequent to identifying a suitable cell on the one radio technology, cells on another of the plurality of radio technologies are also monitored in order to identify if one of the monitored cells is more suitable than the cell identified on the one radio technology. Subsequent to the monitoring, the cell identified from all of the radio technologies searched as the most suitable is selected and camping for the first time occurs onto that cell.

Abstract: The invention concerns a process for assigning radio resources between a number M of multiplexed transport channels in a physical channel, each transport channel carrying a service and/or data having a requirement of a specific QoS between a user terminal and a base station of a cellular telecommunications network. The process of the invention comprises the following steps of: a)—estimating the QoS of each of the transport channels received b)—determining N services among the M services for which QoS is greater than a predetermined target value, c)—reducing the proportion of the physical channel allocated to the N transport channels determined in the step b) by modifying their flow adaptation parameters, d)—waiting for convergence of the power control loop, e)—performing the steps c) and d) until the specific QoS of each channel is attained with minimal transmission power of the physical channel.

Abstract: In a turbo coder, rate conversion and/or rate matching is achieved by deleting parity bits P1 and P2 from the outputs of two constituent coders, one supplied with data bits to be coded and the other supplied with the same data bits after interleaving. Deleted bits are determined by a rate matching control unit directly for the P1 bits and via a similar position interleaving step for the P2 bits. A similar rate matching arrangement is provided for only two of the three outputs of a rate ⅓ convolutional coder, the third output corresponding to a strongest coding polynomial in terms of minimum free distance and none of its coded data bits being deleted.

Abstract: The sender includes a first source of M-ary symbols and a second source of M′-ary symbols, with M′>M>1, for example M=2, M′=8. The frames delivered by one of the sources are interleaved into successive blocks each including symbols obtained from at least two frames. Each block gives rise to a burst of modulated signal produced either by a first modulator of M-ary symbols or by a second modulator of M′-ary symbols. In response to a change of the active source, certain M-ary symbols originating from the first source are converted into M′-ary symbols to produce at least one block of M′-ary symbols submitted to the second modulator and including both symbols from at least one frame delivered by the second source and symbols obtained by conversion of M-ary symbols from at least one frame delivered by the first source.
