Abstract: There are disclosed various methods, apparatuses and computer program products for video encoding and decoding. In some embodiments information on bit-depth of a reference block of an image on a first layer and bit-depth of a current block of an image on a second layer is obtained. The obtained information is used to select one or more resampling filter parameters for filtering at least a part of a reference layer image to be used in inter-layer prediction. There are also disclosed corresponding methods, apparatuses and computer program products for video encoding and decoding.

Abstract: An approach is provided for social networking-based item installation. A social network platform receives a request from at least one device, a service, or a combination to initiate an installation of at least one item. The platform processes and/or facilitates a processing of information associated with the at least one device, the request, or a combination thereof to determine at least one other device. The service platform then determines to cause, at least in part, an initiation of the installation of the at least one item at the at least one device, the at least one other device, or a combination thereof.

Abstract: The invention relates to a method for encoding, a method for decoding, an apparatus, computer program products, an encoder and a decoder for video information. The motion vector for a block in a video image is predicted from a set of motion vector prediction candidates determined based on previously-coded motion vectors. A motion vector prediction candidate is included in the set based on the location of the block associated with the first spatial motion vector prediction candidate and in comparison with motion vector prediction candidates already in the set.

Abstract: A method and apparatus are provided for encoding and decoding image information. The encoding comprises receiving a block of pixels; creating a set of motion vector prediction candidates for the block of pixels; and examining the set to determine if a motion vector prediction candidate is a temporal motion vector prediction, or a spatial motion vector prediction. If the motion vector prediction candidate is a temporal motion vector prediction, the motion vector prediction candidate is kept in the set. If the motion vector prediction candidate is a spatial motion vector prediction, it is examined whether the set comprises a motion vector prediction candidate corresponding with the spatial motion vector prediction; and if so, the motion vector prediction candidate is removed from the set. Once the set is created, one of the candidates from the set is selected to represent a motion vector prediction for the block of pixels.
