Abstract: A method for delivering motion video, which is captured by a first motion video camera, to a client device from said first motion video camera. The method comprises receiving, at the first motion video camera from the client, a request of a motion video and an indication of a requested format, matching, in a transcoding format list of the first motion video camera, the selected format to an address of a second motion video camera, sending, to said address of the second motion video camera, a motion video which have been identified in a request, the motion video having a format different from the selected format, receiving at the first motion video camera from the second motion video camera said requested motion video in the selected format, and sending said requested motion video in the selected format to the client.

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.
