Signal processing device and method for 3d service

A method of processing a three-dimensional (3D) service, the method comprising:

• receiving, by a 3D service processing device, a first signal via a terrestrial broadcasting network, the first signal carrying a base view component for the 3D service that is multiplexed with signaling information,
• wherein the signaling information includes a private section and the private section includes reference information for accessing an additional view component to be paired with the base view component, and
• wherein the reference information includes uniform resource identifier (URI) information of the additional view component for the 3D service;
• receiving, by the 3D service processing device, a second signal via an interactive network, the second signal carrying the additional view component for the 3D service;
• decoding, by the 3D service processing device, the first signal;
• extracting, from the first signal, linkage information for pairing the base view component and the additional view component,
• wherein the signaling information includes a virtual channel table_(VCT) and an event information table (EIT), and
• wherein the VCT and the EIT include information for signaling a service type of the 3D service, and wherein the first signal includes first synchronization information for synchronizing the base view component;
• searching, by the 3D service processing device, for a video stream position for pairing the base view component and the additional view component based on the pairing information and obtaining the first synchronization information of the base view component or a second synchronization information of the additional view component,
• wherein the first synchronization information has a value that is different than a value of the second synchronization information;
• and
• rendering, by the 3D service processing device, the 3D service based on the pairing information and the obtained first synchronization information or the second synchronization information.

A method of processing a three-dimensional (3D) service, the method comprising:

• receiving, by a 3D service processing device, a first signal including a first video stream and linkage information via a first channel;
• receiving, by the 3D service processing device, a second signal including a second video stream via a second channel;
• searching, by the 3D service processing device, for a video stream position for pairing the first video stream and the second video stream based on the linkage information;
• and
• generating, by the 3D service processing device, the 3D service based on the paired first and second video streams, and at least one of first synchronization information for synchronizing the first video stream or second synchronization information for synchronizing the second video stream.

A three-dimensional (3D) service processing device, comprising:

• a first receiver configured to receive a first signal including a first video stream and linkage information via a first channel;
• a second receiver configured to receive a second signal including a second video stream via a second channel;
• and
• circuitry configured to:
• search for a video stream position for pairing the first video stream and the second video stream based on the linkage information, and
• generate the 3D service based on the paired first and second video streams, and at least one of first synchronization information for synchronizing the first video stream or second synchronization information for synchronizing the second video stream.
