Synchronous 2D/3D Switching System for Service-Compatible 3DTV Broadcasting

Abstract

This paper proposes a new broadcasting system for the service‐compatible 3DTV in which the 3D service can coexist with the conventional digital TV broadcast. In the proposed system, the commercial 3DTV service can be implemented via the existing DTV channel without utilizing the dedicated 3DTV system. This 2D/3D system interworks with the conventional system and can switch to 2D or 3D service according to the broadcast programming and schedule. The system also provides a mechanism that can prevent the synchronization mismatch between left and right video streams and between the stream and the associated signaling in the 2D/3D transition periods. The picture quality measurements are carried out based on the ITU‐R recommended test to check the level of quality of service provided by the proposed scheme. The conformity tests are also performed with the conventional channel and the receiver for the DTV system to confirm the feasibility of the proposed one for the commercial service.

Seamless Video Switching System for Service Compatible 3DTV Broadcasting

“…To do so, a system that allows the selection of a 3DTV service according to the program schedule information was proposed. The 2D/3D service change controller used in this system conducts the following sequential roles: controls the multichannel encoder bitrate, drives the 2D/3D program specific information protocol (PSIP) encoder, controls the 3D remux, and finally, conducts the switching in the remux [15].…”

“…This system can also provide a service conversion for variable multi-channel services with a similar system structure. More details on the functions of each block are discussed in [15].…”
