A method for providing data from a network camera performed in a processing unit of a portable device having a physical communication interface, whereby the portable device has been associated with the network camera. The method comprises: upon detecting a connection to a connected client device at the physical communication interface, establishing a connection to the associated network camera using association data that have been received from the associated network camera when the portable device became associated with the network camera; receiving data from the network camera via the established connection; and transmitting the received data to the connected client device. A portable device and a system of a portable device and a network camera are also disclosed.

Method and a device for providing data from a network camera

An image processing device, a camera and a method of encoding a sequence of video images into a single video stream with dynamic bitrate are provided. The sequence of video images is encoded into frames of a base layer of the single video stream using a base layer resolution and a base layer compression level. Video images of the sequence of video images corresponding to respective times before detecting an event trigger are encoded into a first set of frames of an extended layer of the single video stream. The event trigger is detected and upon detecting the event trigger, video images of the sequence of video images corresponding to respective times after detecting the event trigger are encoded into a second set of frames of the extended layer using a higher resolution than the base layer resolution or a lower compression level than the base layer compression level.

Image processing device, a camera and a method for encoding a sequence of video images

A method of encoding digital video data corresponding to a sequence of input video frames is disclosed. The input video frames are encoded into a sequence of output video frames. The method comprises encoding a first input video frame in a first encoder instance using intra-frame encoding to produce a first intra-frame, decoding the first intra-frame to produce a first decoded frame, encoding the first decoded frame in a second encoder instance to produce a first output video frame. A digital video encoding system is also disclosed, as well as a camera comprising such a system, and a computer program product for performing the method.
