A temporal sequence of pictures is generated in a method for encoding of a first video stream. To do so, a synchronization signal can be used, which can be derived from a second video stream independently of the first video stream. Alternatively, the encoding of a second video stream independent of the first video stream can be based on the same principle as for the encoding of the first video stream.

Method for encoding of a video stream

Methods and devices transform image data, which are transformed by a compression filter before being compressed and stored in a reference image memory. In an extension, an inverse transformation to that of the compression filter is performed by a decompression filter when image data from the reference memory are read out and decompressed. The methods and devices can be used for image compression methods and image decompression methods that use reference image memories.

A temporal sequence of pictures is generated in a method for encoding of a first video stream. To do so, a synchronization signal is used which is derived from a second video stream independently of the first video stream, or the encoding of a second video stream independent of the first video stream is based on the same principle as for the encoding of the first video stream.

A reconstructed image is provided within the framework of predictive coding. The reconstructed image is compressed according to a coding mode of an image coding device and stored in a reference image memory.

Multiple cameras are configured for use in video analytics. A single configuration tool is provided. The interrelationships between cameras are included within the configuration. Using a combination of text entry fields, registration of the cameras on a floor or other map, and marking on images from the cameras, an efficient workflow for configuration may be provided.

A method determines a predicted image area for an image area, in which a temporal predictor for the image area is determined based on a reconstructed image that precedes said image, a local predictor for the image area is determined within a reconstructed image area of the image, a margin of error between the image area and the image area predicted image area is determined by the local predictor using the reconstructed image area and by the temporal predictor using one of the preceding images. A predicted image area can be reconstructed. Also disclosed are an establishing device for carrying out the method for determining a predicted image area as well as a reconstructing device for carrying out the reconstruction method.
