    摘要： Provided are a data processing method and device based on integrated access and backhaul (IAB) using 5G NR wireless communication technology. A method of a relay node may be provided for processing uplink user data. The method may include: receiving uplink user data from a user equipment; deriving a user equipment bearer identifier (UE-bearer-ID) by using logical channel identification information linked to an RLC PDU of uplink user data; selecting a backhaul RLC channel for transmission of uplink user data on the basis of at least one among a user equipment bearer identifier and donor base station address information; and transmitting uplink user data, via the selected backhaul RLC channel, to a donor base station or another relay node.

    摘要： According to the present invention, there is provided a method of decoding an image, the method including: partitioning a current block into multiple sub-blocks; performing intra prediction on a first sub-block among the multiple sub-blocks by using a first sub reference sample line; and performing intra prediction on a second sub-block among the multiple sub-blocks by using a second sub reference sample line. Herein, an intra prediction mode of the first sub-block and an intra prediction mode of the second sub-block are the same.

    摘要： Provided is creating an augmented reality video using a set-top box. The set-top box may include a communication circuit and a processor. The communication circuit may be configured to receive a first video stream including a target object image in real time from a server and to receive a second video stream captured by a user device from the user device. The processor may be configured to: extract the target object image from each frame of the first video stream using WebGL, correct a color of a boundary line of the target object image between the target object and the background, and composite the extracted target object image into an each frame of the second video stream.
