  • Video Encoding Apparatus, Three-Dimensional Broadcast Transmission Apparatus and Method Including the Same
    Publication number: 20260075246
    Abstract: The present invention relates to a video encoding apparatus, a three-dimensional (3D) broadcast transmission apparatus including the same, and a 3D broadcast transmission method, and the video encoding apparatus includes a memory configured to store a program for encoding a 3D video and a processor configured to execute the program stored in the memory, wherein the processor encodes a downsampled low-resolution additional view to generate a base layer bitstream, upscales the encoded low-resolution additional view, and secondarily encodes a residual signal between a reference view and the upscaled additional view to generate an enhancement layer bitstream.
