Method and system for remotely controlling consumer electronic devices
Publication/Patent Number: US10904589B2 Publication Date: 2021-01-26 Application Number: 16/568,445 Filing Date: 2019-09-12 Inventor: Gordon, Donald F.   Assignee: Gracenote, Inc.   IPC: H04N21/234 Abstract: A media system replaces content in a first sequence of media content. The media system presents the first sequence of media content to an end-user and generates a fingerprint of the sequence of media content. The fingerprint is for comparison with a plurality of reference fingerprints so as to identify the first sequence of media content and determine a reference position within the first sequence of media content. The media system sends a request for a replacement sequence of content to a content replacement system, and receives replacement media content selected based on the identified first sequence of media content. The media system presents the replacement media content to the end-user instead of the first sequence of media content. Presenting the replacement media content begins at a position in the first sequence of media content that is determined based on the reference position.

IMAGE DATA ENCODING/DECODING METHOD AND APPARATUS
Publication/Patent Number: EP3800891A1 Publication Date: 2021-04-07 Application Number: 20209245.8 Filing Date: 2017-10-10 Inventor: Kim, Ki Baek   Assignee: Kim, Ki Baek   IPC: H04N19/52 Abstract: Disclosed is an image data encoding/decoding method and apparatus. A method for decoding a 360-degree image comprises the steps of: receiving a bitstream obtained by encoding a 360-degree image; generating a prediction image by making reference to syntax information obtained from the received bitstream; combining the generated prediction image with a residual image obtained by dequantizing and inverse-transforming the bitstream, so as to obtain a decoded image; and reconstructing the decoded image into a 360-degree image according to a projection format. Here, the step of generating the prediction image comprises the steps of: obtaining, from motion information included in the syntax information, a motion vector candidate group including a motion vector of a block adjacent to a current block to be decoded; deriving a prediction motion vector from the motion vector candidate group, on the basis of selection information extracted from the motion information; and determining a prediction block for the current block to be decoded, using a fmal motion vector derived by adding the prediction motion vector to a differential motion vector extracted from the motion information.
