Abstract: A method for enhancing quality of an image comprises deriving from an initial low-resolution image (LRI) an initial high-resolution image (IHRI) by upsampling (S2, S3), providing (S4), based on the initial low-resolution image (LRI), at least one downsampled filtered image (AIij, AIi?j?) with lower resolution, providing (S6), based on the initial low-resolution image (LRI), an unfiltered image (LRI, UIi?j?) having same resolution as the downsampled filtered image, selecting a patch (PI) from the initial high-resolution image (IHRI), finding (S8) filial patches (PA k) similar to the selected patch in the downsampled filtered image (AIij, AIi?j?), finding, in the unfiltered image (LRI, UIi?j?), parent patches (PPk) locally associated to the filial patches (PAk), and linearly combining (S14) the parent patches (PPk) to form an enhanced quality patch (EP).

Abstract: In scalable video coding, Enhancement Layer (EL) pictures are usually predicted from decoded Base Layer (BL) pictures. When the EL pictures and the BL pictures are represented with different color spaces, color gamuts, transforming the decoded BL pictures, for example, to Inter-Layer Reference (ILR) pictures in the color space/gamut of the EL may improve the prediction. To accurately predict from the BL, the color space of the BL pictures can be partitioned into multiple octants, wherein each octant is associated with a respective set of color mapping function (CMF) parameters. The partitioning of color space may cause color discontinuity artifacts in the ILR pictures. In one embodiment, we avoid using a block of an ILR picture as a prediction block for the EL pictures if we determine that a color discontinuity artifact may exist in the block of the ILR picture.

Abstract: A 3D model can be modeled using “pattern-instance?representation. To describe the vertices and triangles, properties of the instance, for example, texture, color, and normal, are adjusted to correspond to the order in the pattern. The texture of an instance is encoded depending on its similarity with the texture of a corresponding pattern. When instance texture is identical or almost identical to the pattern texture, the instance texture is not encoded and the pattern texture will be used to reconstruct the instance texture. When the instance texture is similar to the pattern texture, the instance texture is predictively encoded from the pattern texture, that is, the difference between the instance texture and pattern texture is encoded, and the instance texture is determined as a combination of the pattern texture and the difference.

Abstract: A method performed by a set-top box operating on a network includes generating an indicia containing a media access control address of the set-top box and a first uniform resource locator which is displayed for scanning by a companion device. The set-top-box receives entitlements for activation if the entitlements were previously granted. If the entitlements were not previously granted, the set-top box receives a second uniform resource locator with which it generates an updated indicia which is displayed for scanning by the companion device. The set-top-box then receives entitlements for activation of the set-top box if initiation of the subscription occurs. The set-top box removes the updated indicia from display and uses the entitlements to active the set-top box to receive multimedia content on the network.

Abstract: Accuracy and efficiency of video quality measurement are major problems to be solved. According to the invention, a method for accurately predicting video quality uses a rational function of the quantization parameter QP, which is corrected by a correction function that depends on content unpredictability CU. Exemplarily, the correction function is a power function of the CU. Both QP and CU can be computed from the video elementary stream, without full decoding the video. This ensures high efficiency.

Abstract: A method of operating a device for indicating an event notification to a user comprises indicating a new event through accordingly controlling visual, audible and/or tactile indicators. A user input is received in response to the indicated event. In case a user input in response to the indicated event is not received within a first time period, sensors in the device are controlled to monitor ambient conditions and determine corresponding pattern. In case of a change in the pattern of the ambient conditions by a predetermined amount within a second time period, the new event is indicated once more to the user.
