Abstract: A method of encoding video is provides encoding of panic scenes efficiently. The method includes receiving an input video at an encoder, reviewing lookahead information from a second encoder that processed the input video ahead of the encoder that indicates positions of panic scenes within the input video that caused the second encoder to enter a panic encoding mode during which it skipped the encoding of frames, entering a pre-panic stage with the encoder ahead of said panic scenes, entering a semi-panic stage with the encoder during the panic scenes when it produces a bitstream having a number of bits exceeding a predetermined data size within an encoder buffer, and entering a full panic stage when the semi-panic stage does not bring the number of bits in the bitstream below the predetermined data size.

Abstract: The present technique relates to an image processing device and method for preventing increases in the processing load of image encoding and decoding. The image processing device includes: a temporal prediction control unit that controls, in a prediction of a motion vector, whether a temporal prediction is to be performed to predict the motion vector by using the motion vector of a neighbor region temporally adjacent to the current region being processed; and a motion vector encoding unit that predicts the motion vector of the current region by performing only a spatial prediction to predict the motion vector from the motion vector of a neighbor region spatially adjacent to the current region or performing both the spatial prediction and the temporal prediction under the control of the temporal prediction control unit, and encodes the motion vector of the current region by using the predicted value.

Abstract: A method of coding video data includes receiving video information associated with a first layer and a second layer and determining whether at least one of the first layer and the second layer is a default layer. The method can include at least partially restricting inter-layer prediction when neither the first layer nor the second layer is the default layer. A default layer can be a base layer or an enhancement layer. A flag can be received that indicates that inter-layer prediction is to be restricted. In addition, the method can include determining whether inter-layer prediction is allowed for the video information associated with the first layer, and determining whether inter-layer prediction is partially allowed for the video information associated with the second layer such that motion compensation is not used with the second layer video information.
