    摘要: Adaptive video encoding and decoding methods and apparatuses for encoder-assisted frame rate up-conversion (EA-FRUC) are described herein. An encoder selectively encodes at least a portion of a video frame, such as a block, using an interpolated FRUC frame as a reference. The encoder interpolates at least a portion of the FRUC frame at the same time instance as the yet to be encoded video frame, and selects one of a plurality of FRUC encoding modes for that portion, e.g., based on rate distortion (RD). The encoder encodes the frame using the selected FRUC encoding mode, the FRUC reference frame, and any additional reference frames that may be indicated. A decoder interpolates the FRUC frame and uses it for decoding with knowledge of the particular FRUC mode that was used by the encoder. The encoder communicates the FRUC mode for a block via one or more existing parameters in the encoded video frame.

    摘要: The invention generally relates to multimedia data processing, and more particularly, to processing operations performed prior to or in conjunction with data compression processing. A method of processing multimedia data includes receiving interlaced video frames, obtaining metadata for the interlaced video frames, converting the interlaced video frames to progressive video using at least a portion of the metadata; and providing the progressive video and at least a portion of the metadata to an encoder for use in encoding the progressive video. The method can also include generating spatial information and bi-directional motion information, for the interlaced video frames, and generating progressive video based on the interlaced video frames using the spatial and bi-directional motion information.

    摘要: This disclosure is directed to techniques for encoding and decoding transitional effects, i.e., visual video effects that are used to transition from a current scene of a multimedia sequence. According to the disclosed techniques, an encoding device detects a transitional effect associated with a multimedia sequence during the encoding of the multimedia sequence, and transmits information as part of an encoded multimedia sequence to identify the transitional effect associated with the encoded multimedia sequence to a decoder. The information may comprise metadata that can be used by the decoder to simulate or re-create the transitional effect. The decoder simulates a transitional effect in response to the information.
