High-Resolution Imagery from Two Data Streams

Side-by-side is not the only possibility when it comes to broadcasting and distributing 3D image streams. If there is no need to retain frame compatibility with existing MPEG-2 based broadcasting, there are a number of ways to transmit natural 3D images with no resolution degradation. One of these is the dual-stream approach (Fig. 5).

Diagram outlines dual stream broadcasting, now being considered for simultaneous transfer of multiple data streams. Korea is expected to begin 3D broadcasting in October 2010, packing MPEG-2 and H.264 data into a single channel on terrestrial waves (a). MVC and Sensio’s SENSIO Advanced also use dual streaming (b). The National Institute of Information and Communications Technology (NICT) is working on a concept called “depth broadcasting,” which will add depth information via the network to standard 2D broadcast data (c).
