Abstract: A network device receives, from a first video camera system, position information for a first video camera at a first site and sends, to a second video camera system, position instructions for a second video camera at a second site. The position instructions are configured to locate the second video camera within the second site to correspond to a relative position of the first camera in the first site. The network device receives, from the first video camera system, a first video feed including images of the first site and receives, from the second video camera system, a second video feed including images of a subject of the second site. The network device combines the first video feed and the second video feed to generate a synchronized combined video feed that overlays the images of the subject of the second video feed in images of the first site.

Abstract: Methods and encoders and decoders for adaptively quantizing transform domain coefficients in image and/or video encoding/decoding. For an image having a number of blocks, each block having N coefficients, the quantization step size for each coefficient is selected dynamically, thus resulting in a quantizer that may apply different step sizes to different coefficients. The selected step sizes for each coefficient are used for those coefficients within all blocks in the image/frame. In one aspect, the step sizes are selected on the basis of balancing pixel domain distortion when the image/frame is decoded.

Abstract: The invention is related to prediction of a lost or damaged block of an enhanced spatial layer frame. A method for predicting a lost or damaged block of an enhanced spatial layer frame comprises the steps of determining an adjuvant frame in the enhanced spatial layer by help of reference information from a lower spatial layer frame corresponding said enhanced spatial layer frame, generating an information reduced block by help of said adjuvant frame and predicting the lost or damaged block by help of the information reduced block. The reference information of the corresponding lower spatial layer frame can be decoded independently from any lower spatial layer reference frame and the adjuvant enhanced spatial layer frame is already decoded. Thus, the computational effort is reduced. By generation of the information reduced block the prediction is made smoother which makes it less vivid and therefore less salient to a user.
