Abstract: A portable device, and a method performed in a portable device, for associating media captured by the portable device to one or more parties having requested the media to be captured at one or more locations. The method comprises: receiving information associating each of the one or more parties with a location; dynamically determining a location of the portable device; dynamically associating the media captured by the portable device to the one or more parties, such that media currently being captured by the portable device is associated with a party that according to the received information is associated with a current location of the portable device.

Abstract: A method for re-provisioning a user equipment (UE, 140) after a first digital security certificate for the UE (140) has expired includes communicating content data to a controller (130) over a first secure communication channel after verification of a validity of a first digital security certificate. Once it is realized the first digital security certificate has expired, the UE (140) sends a certificate provisioning request message over an unsecure channel to the controller (130) as a request to the controller (130) to provision a second digital security certificate. The UE (140) signs the certificate provisioning request message with the private key for the now expired first digital security certificate. A second digital security certificate is signed by the rescue-secret private key at the controller (130) and sent to the UE (140), which verifies its authenticity with the corresponding rescue-secret public key.

Abstract: Playback of motion video is presented. A method may comprise requesting streaming of a specific motion video sequence from a storage device to a playback device, streaming motion video data of the requested motion video sequence, displaying the streamed motion video data as the streamed motion video data is received, and sending a request of change of playback speed to the data storage device. In response to the request, decoding, in the data storage device, motion video data from a temporal position in the specific motion video sequence that has not yet been streamed to the playback device, compressing, in respect of time, the decoded motion video data, encoding the compressed motion video data using an encoding scheme corresponding to an encoding scheme used to encode the specific motion video sequence, and continue streaming the motion video sequence to the playback device using the compressed and encoded motion video data.

Abstract: A method (200) and an object analyzer (104) for analyzing objects in images captured by a monitoring camera (100) uses a first and a second sequence of image frames, wherein the first sequence of image frames covers a first image area (300) and has a first image resolution, and the second sequence of image frames covers a second image area (302) located within the first image area (300) and has a second image resolution higher than the first image resolution. A common set of object masks is provided wherein object masks of objects (304) that are identified as being present in both image areas are merged.

Abstract: A method and a video camera for recording an event initiated video sequence includes storing captured video frames in a video buffer, detecting a first event, and in response, initiating a video sequence recording session for recording of a video sequence in a non-volatile memory. Pre-event video frames and post-event video frames related to the first event are recorded, where the post-event time period starts at the detection of the first event. A first event delay time period is started in response to the expiration of the post-event time period. The video sequence recording session is closed if a delay period expires and no other event process is in progress.
