摘要: A user equipment for providing information most relevant to a user as the user becomes impaired or experiences diminishing capacity is disclosed. The user equipment includes a transceiver, a memory, at least one sensor for detecting a biometric measurement of a user of the equipment, a user interface and a processor. The processor filters the biometric measurement, calculates a metric based on the measurement, evaluates the metric, selectively adjusts an amount of information displayed on the user interface based on the evaluated metric and executes an application corresponding to a user actuation of an item of the displayed information.

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 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: Hence a method is provided for determining a quality value of a video stream, comprising the steps of: identifying lost data packets of the video stream; identifying at least two intra coded frames of the video stream; determining intra coded frames having a maintained image quality, based on estimating if a lost data packet is associated with an intra coded frame; estimating a distance between each one of the lost data packets and a next respective, subsequent intra coded frame having a maintained image quality; and generating the quality value, based on the distances. A system and a computer readable medium are also described.
