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. |
