20130343459 | METHOD AND APPARATUS FOR VIDEO CODING - There is provided a method, apparatus and computer program product. In some embodiments an uncompressed picture is encoded into a coded picture comprising a slice; determining a list of prediction reference candidates for the slice in one or more temporal reference pictures; associating each prediction reference candidate in the list with a reference index; and examining if the prediction reference candidate associated with a first reference index is available for temporal motion vector prediction for the slice. If the prediction reference candidate with the first reference index is not available for temporal motion vector prediction for the slice, examining if the list comprises another prediction reference candidate associated with another reference index. If the list comprises another prediction reference candidate associated with another reference index, providing the reference index associated with the another prediction reference candidate in a syntax element at a slice level or at a higher level. | 12-26-2013 |

20140085415 | METHOD AND APPARATUS FOR VIDEO CODING - There are disclosed various methods, apparatuses and computer program products for video encoding and decoding. In some embodiments the method for encoding comprises obtaining samples of a video signal for encoding a first layer representation of the video signal and a second layer representation of the video signal. An encoded first layer representation of the video signal is used as a prediction reference in the encoding of the second layer representation of the video signal. It is evaluated whether to use filtering in the encoding of the second layer representation. If the evaluation indicates to use filtering in the encoding of the second layer representation, the method further comprises filtering the encoded first layer representation; and using the filtered encoded first layer representation as the prediction reference in the encoding of the second layer representation of the video signal. | 03-27-2014 |
20140086327 | METHOD AND TECHNIQAL EQUIPMENT FOR SCALABLE VIDEO CODING - The invention relates to video coding, in particular to scalable video encoding/decoding. A method according to an embodiment comprises encoding motion information of an enhancement layer using motion vector information of a base layer, wherein the encoding comprises deriving the reference index of motion vector of the enhancement layer by using a mapping process depending on the used reference picture list of the base layer and the reference index of motion vector of the base layer, and determining corresponding pictures of the enhancement layer and the base layer by mapping the respective reference picture indexes to corresponding picture order values. The embodiments relate to decoding also. | 03-27-2014 |

20140218473 | METHOD AND APPARATUS FOR VIDEO CODING AND DECODING - There are disclosed various methods, apparatuses and computer program products for video encoding and decoding. In some embodiments diagonal inter-layer prediction is enabled by providing an indication of a reference picture. In some embodiments the indication is provided as a combination of a temporal picture identifier and a layer identifier of the reference picture in another layer than the picture to be predicted. In an encoding method a first picture of a first layer representing a first time instant is encoded; a second picture representing a second time instant on a second layer is predicted by using the first picture as a reference picture; and | 08-07-2014 |
20140219346 | METHOD AND APPARATUS FOR VIDEO CODING AND DECODING - Various methods, apparatuses and computer program products for video encoding and decoding. In some embodiments a first picture having a first resolution on a first layer is encoded without inter-layer prediction; a second picture having a second resolution on a second layer is encoded without inter-layer prediction; a third picture having the second resolution on the second layer is encoded without inter-layer prediction and without temporally referencing to pictures prior to the second picture. Further, a corresponding indication is encoded. In some embodiments one or more indications are received to determine if a switching point, referring to a picture coded using inter-layer prediction, from the first layer to the second layer exists, and if so, pictures in the first layer prior to the switching point; pictures associated with the switching point; and pictures in the second layer after the switching point may be decoded. | 08-07-2014 |
