Abstract: A method and an apparatus for playing back recorded video from a temporal position within a temporal range of the recorded video is disclosed. The recorded video including intra frames and inter frames and the recorded video including video sequences having different frame rates. The method comprises receiving a request for playing back the recorded video from a specific temporal position recorded in the recorded video, identifying an intra frame at an earlier temporal position in the recorded video than the specific temporal position received in the request, playing back the recorded video in a first mode from the identified intra frame, and playing back the recorded video in a second mode from the specific temporal position in the recorded video when the playing back of the recorded video in the first mode have arrived at the specific temporal position of in the recorded video.

Abstract: A control device for controlling an electronic device over a communication network; the electronic device comprises data storage having control parameters and associated access levels which control operation of the electronic device; circuitry which generates a control setup message including the control parameters and access levels; and a network interface for sending the control setup message. The control device comprises: circuitry for determining an access level of a user logged in to the control device; a network interface for receiving the control setup message; control interface setup circuitry for generating a set of control parameters, extract control parameters having an access level equal to or lower than the access level of the user logged in to the control device; and a graphic generating circuitry for generating a graphical control interface comprising control graphics enabling control of different states of operation of the electronic device corresponding to the extracted control parameters.

Abstract: A method, video server, and system for playing back recorded video based on comparing the encoder frame rates at temporal positions of a received video sequence to a predetermined threshold and changing the playback frame rate to a playback frame rate greater than the encoder frame rate if the encoder frame rate is below the predetermined threshold and changing the playback frame rate to the encoder frame rate if the encoder frame rate is greater than the predetermined threshold. The recorded video is thereby played back in a time efficient manner, decreasing the total time period for video playback, and assisting a security operator in finding parts of the recorded video that may be of interest.
