Abstract: Disclosed is a unified speech and audio coding (USAC) audio signal encoding/decoding apparatus and method for digital radio services. An audio signal encoding method may include receiving an audio signal, determining a coding method for the received audio signal, encoding the audio signal based on the determined coding method, and configuring, as an audio superframe of a fixed size, an audio stream generated as a result of encoding the audio signal, wherein the coding method may include a first coding method associated with extended high-efficiency advanced audio coding (xHE-AAC) and a second coding method associated with existing advanced audio coding (AAC).

Abstract: A method and apparatus for widening a viewing angle in a video conferencing system are provided. The apparatus for widening a viewing angle in a video conferencing system includes: generating reference data from images of a video conference participant captured by a camera included in the video conferencing system; generating movement data based on the video conference participant's movements sensed by the camera; extracting a first control parameter by comparing the reference data with the movement data; transmitting the first control parameter to the other end of the conference; receiving a second control parameter generated at the other end of the conference; and controlling the camera by the second control parameter.
