Abstract:
PURPOSE: A device for providing a 3D service by interlinking a separately transmitted additional image with a reference image transmitted in real time and a method thereof are provided to form a high definition 3D service by inserting a signaling plan for a reference relation between two images and time information. CONSTITUTION: A real time reference image stream is decoded as a reference image(10) through a reference image generator(130). The real time reference image stream is delivered to a 3D play unit(160). Interlinking information and synchronization information in the real time reference image stream are delivered to a reception and storage unit(150). The reception and storage unit delivers a file or an additional image-related stream to be interlinked with the reference image and an additional image(20) synchronized with the reference image to the 3D play unit through the interlinking information and the synchronization information.

Abstract:
DVB(Digital Video Broadcasting) 기반으로 방송 서비스를 제공하는 방송 서비스 제공 장치는 방송 스트림을 부호화하여 기본스트림을 생성하고, 가상 채널 번호 서술자를 생성하여 상기 가상채널 번호 서술자에 가상 채널 번호를 할당한 다음, 가상 채널 번호 서술자를 포함하는 서비스 정보를 생성하며, 기본스트림과 서비스 정보를 다중화하여 전송한다.
Abstract:
PURPOSE: A receiver and a hybrid service providing method thereof are provided to individually output value added data for each of content by using signaling data. CONSTITUTION: A receiver (200) comprises a first receiver (210), a second receiver (220), an output unit (230), a control unit (240), and a storage unit (250). The first receiver receives signaling information and a first signal including reference data through a radio frequency (RF) broadcast network. The control unit detects a plurality of additional data source information from the signaling information. The second receiver receives a second signal including additional data from a source device corresponding to data source information by connecting to an internet protocol (IP) communication network. A storage unit stores the reference data included in the first signal and the additional data included in the second signal. An output unit outputs the reference data and the additional data by individually processing the reference data and the additional data.
