METHOD FOR DECODING VIDEO SIGNAL ENCODED THROUGH INTER-LAYER PREDICTION |
摘要 |
A method for decoding a video signal encoded through inter-layer prediction is provided. When encoded bitstreams of first and second layers are received and decoded into a video signal, pictures of the first layer are predicted from pictures of the second layer. It is determined whether or not inter-layer prediction is constrained under the condition that a target block in the first layer has been coded in an intra mode through prediction from a picture of the second layer. An operation for checking a flag "intra_base_flag" indicating whether or not image data of the target block has been coded into difference data with reference to residual data, coded in an intra mode, of a corresponding block of a different layer is skipped if it is determined that inter-layer prediction is constrained. This eliminates the need for an encoder to transmit the flag under the same condition. |
