  • Method and an apparatus and a computer program product for video encoding and decoding
    Patent number: 10582198
    Abstract: The invention relates to a method and technical equipment, wherein the method comprises obtaining a picture sequence; selecting a first spatial region and a second spatial region within a picture area of pictures of the picture sequence, the second spatial region differing from the first spatial region; obtaining a first spatial region sequence, the first spatial region sequence comprising the first spatial region of the pictures of the picture sequence; obtaining a second spatial region sequence, the second spatial region sequence comprising the second spatial region of the pictures of the picture sequence; transmitting the first spatial region sequence at a first picture rate; and transmitting the second spatial region sequence at a second picture rate, the first picture rate being different from the second picture rate.

  • Video encoding and decoding methods and apparatuses for padding area of image
    Patent number: 10321155
    Abstract: Provided is a video encoding method including: performing padding outside an input image such that a size of the input image is a multiple of a maximum coding unit; when a current maximum coding unit includes a padding area generated via the padding, determining a coding unit by splitting the current maximum coding unit by using a boundary of the input image and the padding area; determining information indicating whether a coding unit included in the padding area includes a nonzero coefficient to be 0; and encoding a bitstream including the determined information.

  • Systems, methods, and media for managing an interactive streaming image system
    Patent number: 7668965
    Abstract: Systems, methods and media for managing an interactive streaming image system are disclosed. More particularly, hardware and/or software for generating, encoding, and transmitting image frames to an interactive client are disclosed. One embodiment provides a method for streaming images from a server to a client. Embodiments may include receiving from the client via a network client information and generating a new image frame based on the received client information. Embodiments may also include comparing the new image frame and a previous image frame and setting a new compression level based on the comparison between the new image frame and the previous image frame. Embodiments may also include encoding the new image frame based on the new compression level and transmitting the encoded new image frame and an indication of the new compression level to the client via the network.
