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).

USAC audio signal encoding/decoding apparatus and method for digital radio services

A receiving terminal in a hybrid network receives a video stream through a broadcasting network. The receiving terminal receives a high speed video stream streamed at a high speed for a defined first period from a first time when switching from the broadcasting network to a communication network depending on a receiving state of the broadcasting network is determined, receives a live video stream streamed in a live form from any one time of the first period, and generates a continuous video stream using the video stream received through the broadcasting network, the high speed video stream, and the live video stream.

Apparatus and method for receiving video service in hybrid network

A signal transmitting and receiving method and an apparatus for selecting an interference pattern from a security key and transmitting and receiving a signal based on the selected interference pattern are provided.

Method and apparatus for transmitting and receiving signal based on interference

A transmitting apparatus generates a modulation pattern code corresponding to an input security key and modulates and transmits the bit stream with a corresponding modulation method for a duration of a corresponding modulation method while changing a modulation method according to the generated modulation pattern code.

Method and apparatus for transmitting and receiving

A broadcasting signal transmitting device transmits a broadcasting signal including a base layer signal and an enhancement layer signal as well as an additional layer signal relating to the broadcasting signal to a broadcasting signal receiving device. The broadcasting signal receiving device selectively provides the enhancement layer signal and the additional layer signal to the user according to the user's service level. Accordingly, various services are differently provided to the user according to the user level.
