Title:
Adaptive upsampling of multilayer video coding
Document Type and Number:
Japanese Patent JP6141988
Kind Code:
B2
Abstract:
Systems, methods, and instrumentalities are disclosed for adaptive upsampling for multi-layer video coding. A method of communicating video data may involve applying an upsampling filter to a video sequence to create encoded enhancement layer pictures. The upsampling filter may be applied at a sequence level of the video sequence to create the enhancement layer bitstream. The upsampling filter may be selected from a plurality of candidate upsampling filters, for example, by determining whether knowledge of a category related to the video sequence exists and selecting a candidate upsampling filter that is designed for the category related to the video sequence. Upsampling filter information may be encoded. The encoded upsampling information may comprise a plurality of coefficients of the upsampling filter. The encoded upsampling filter information and the encoded enhancement layer pictures may be sent in an output video bitstream. The method may be performed, for example, by an encoder.
