摘要： According to an aspect, a wireless device receives (302) a preview digital image from a computer server and applies object recognition processing (304) to the preview digital image, to determine (306) whether the preview digital image contains a representation of a known object of interest. Responsive to a positive determination, the wireless device transmits (308) an indication of the positive determination. The computer server sends, in response to the transmitted indication, an enhanced digital image corresponding to the preview digital image, or additional image data, which is received (310) by the wireless device. In the latter case, the wireless device forms an enhanced version of the preview digital image using the additional image data. The wireless device at least temporarily stores (312) the enhanced image or image version, e.g., for rendering on a display screen of the device.

摘要： A device (100) for handheld operation is provided. The device comprises a touchscreen (110) and processing means (111) operative to display a plurality of user-interface (UI) elements (121–124) on the touchscreen, wherein each UI element is associated with an action which is performed in response to touching the UI element, determine one or more of the displayed UI elements which a user (150, 151) of the device is likely to touch based on a touch pattern (130), and perform, for at least one of the determined UI elements, the action associated with the UI element. The action may, e.g., comprise pre-fetching content which is likely to be requested by the user from a server (180). Performing an action, such as pre-fetching, based on a touch pattern is advantageous since a touch pattern reflects the relative likelihood that the user touches a specific position, or region, of the touchscreen, thereby reducing latency.

摘要： A communications device (100, 200) for handheld operation comprising a touchscreen is provided, operative to display (401) a plurality of User-Interface (UI) elements on the touchscreen, each of UI elements being associated with a hyperlink, and to select (402) two or more of the UI elements displayed at positions on the touchscreen having the highest relative probability of being touched by a user of, based on a statistical touch pattern reflecting a relative probability that a specific position on the touchscreen is being touched by the user. The communications device (100, 200) is further operative to transmit, for each selected UI element, a request (411–413) for content referenced by the hyperlink associated with the UI element. Each request (411–413) comprises a stream priority value (prio. #1, prio. #2, prio. #3) indicative of a suggested resource allocation for a downlink stream (421–423) carrying the requested content. The stream priority value corresponds to the relative probability that the UI element is being touched.

摘要： There are provided mechanisms for predicting a multimedia session MOS. The multimedia session comprises a video session and an audio session, wherein video quality is represented by a vector of per-time-unit scores of video quality and wherein audio quality is represented by is a vector of per-time-unit scores of audio quality. The multimedia session is represented by a vector of rebuffering start times of each rebuffering event, a vector of rebuffering durations of each rebuffering event, and an initial buffering duration being the time between an initiation of the multimedia session and a start time of the multimedia session. The method comprises generating audiovisual quality features from the vector of per-time-unit scores of video quality and the vector of per-time-unit scores of audio quality. The audiovisual quality features comprise: a vector of per-time-unit scores of audiovisual quality, calculated as a polynomial function of the vector of per-time-unit scores of video quality and the vector of per-time-unit scores of audio quality; a weighted combination of the per-time-unit scores of audiovisual quality, wherein the weights are exponential functions of a time since the start time of multimedia session and a multimedia session duration; a negative bias representing how a sudden drop in per-time-unit scores of audiovisual quality affects the multimedia session MOS; and a term representing a degradation due to oscillations in the per-time-unit-scores of audiovisual quality. The method comprises generating buffering features from the vector of rebuffering start times of each rebuffering event, calculated from the start time of multimedia session, and the vector of rebuffering durations of each rebuffering event. The method comprises estimating a multimedia session MOS from the generated audiovisual quality features and the generated buffering features.

摘要： A method and a communication device (200) for controlling reception of data when a maximum total amount of received data is stipulated for a time period. An amount of data received during said time period is monitored (2:5) and compared with a predicted distribution of data (200A) that the device (200) is expected to receive without exceeding the maximum total amount. An amount of requested data is then reduced (2:6, 2:7) when detecting that the monitored amount of received data exceeds the predicted distribution of data, so that the maximum total amount of data will not be exceeded before the time period expires.

摘要： A mobile electronic device (device) (100) operating with other devices (100) form a group for wireless coordinated playout of audio media content. The processor performs operations that determine a common time sync shared with the other devices, and determine a timing of occurrence of a sound transient sensed relative to the common time sync. The operations receive timing reports from the other devices, where each of the timing reports indicates a timing of occurrence of the sound transient sensed at a respective one of the other devices relative to the common time sync. The sound transient sensed by the devices is generated at a preferred listening location (102). The operations coordinate timing of playout of audio media content by the group of devices responsive to comparison of the timing of occurrence of the sound transient sensed by the microphone of the device and the timing of occurrences indicated by the timing reports.

摘要： There is provided mechanisms for providing information about peer communication devices to a network node. A method is performed by a first peer communication device. The method comprises exchanging, with a second peer communication device over a device-to-device connection, any timestamped identity information and location information about other peer communication devices as previously exchanged with at least one peer communication device other than the second peer communication device. The method comprises adding to the timestamped identity information and location information, timestamped identity information and location information about the second peer communication device as obtained from the second peer communication device. The method comprises forwarding the timestamped identity information and location information to a network node upon network access to the network node.
