  • Patent number: 11622130
    Abstract: Sampled data is packaged in checkerboard format for encoding and decoding. The sampled data may be quincunx sampled multi-image video data (e.g., 3D video or a multi-program stream), and the data may also be divided into sub-images of each image which are then multiplexed, or interleaved, in frames of a video stream to be encoded and then decoded using a standardized video encoder. A system for viewing may utilize a standard video decoder and a formatting device that de-interleaves the decoded sub-images of each frame reformats the images for a display device. A 3D video may be encoded using a most advantageous interleaving format such that a preferred quality and compression ratio is reached.

  • Patent number: 10769247
    Abstract: Method and system for allowing a famous entity to reach out to their audience/fans/the public with comments, explanations and corrections in response to stories/allegations published about them in the media without infringing copyrights of the media owners. Using their portable device, users/fans may take a picture/snapshot or even activate their camera feed over a published page (e.g. magazine/poster/banner, web page) which is by default a copyrighted material. The imaging device transforms a picture of the page into a digest representing a non-copyrighted format of the copyrighted page and sends the digest to a remote server. The server performs a search and comparison between the received digest and pre-stored digests for which a reply was provided by the famous entity (VIP). If a match exists, the server fetches the reply and sends it back to the portable device for rendering on the display device of the portable device.
