  • Patent number: 11659194
    Abstract: A method of adjusting a bitrate of an image based includes: identifying magnitudes of one or more frequency components in the image; determining a frequency filter based on a difference between a current bitrate and a target bitrate of the image such that the greater is the difference between the current bitrate and the target bitrate, magnitudes of the more high frequency components are reduced by the frequency filter; and applying the determined frequency filter to the magnitudes of the one or more frequency components.

  • Patent number: 11412021
    Abstract: A real-time video streaming method between a server and a client according to a real-time transport protocol (RTP)/real-time streaming protocol (RTSP) standard protocol, including transmitting a DESCRIBE command including a Require header from a client to a server, wherein the client and the server support the Require header, receiving session description protocol (SDP) information from the server in response to the DESCRIBE command, receiving, at the client, a video from the server according to the RTP/RTSP standard protocol, in response to an encoding attribute of the video transmitted from the server to the client being changed, describing a changed encoding attribute in an RTP extension header of an RTP packet when the RTP packet is first transmitted in an RTP payload type determined according to the changed encoding attribute, and changing, at the client, a decoding setup based on the changed encoding attribute in the RTP extension header.

  • Patent number: 10999577
    Abstract: A method of determining a quantization parameter includes determining an adjustment range of a quantization parameter correction value based on a size of a motion area of an input image, calculating an average bitrate value of the input image, and adjusting the quantization parameter correction value by decreasing the quantization parameter correction value within the adjustment range in response to determining that the average bitrate value is greater than an upper limit value, and by increasing the quantization parameter correction value within the adjustment range in response to determining that the average bitrate value is equal to or less than a lower limit value.

  • Patent number: 10778878
    Abstract: An apparatus for processing an image includes a camera configured to obtain a fixed image signal based on non-movement of the camera and obtain a variable image signal based on movement of the camera; a communication interface configured to receive a command; a driver configured to move the camera in response to the command; and a processor configured to process the fixed image signal based on a fixed image signal process parameter value, and process the variable image signal based on a variable image signal process parameter value, the variable image signal process parameter value having an image signal process parameter value based upon which a high frequency component of the variable image signal is reduced.
