Abstract
Three dimensional (3-D) program content viewing system in a media environment with different media presentation devices detects a first synchronization signal transmitted from a first synchronization signal source, wherein the first synchronization signal is associated with first 3-D program content and includes a first signal identifier. The system detects a second synchronization signal transmitted from a second synchronization signal source, wherein the second synchronization signal is associated with second 3-D program content and includes a second signal identifier. The system then receives a selection of one of the first synchronization signal and the second synchronization signal and discriminates between the first synchronization signal and the second synchronization signal based upon the first signal identifier and the second signal identifier. The system then controls a left lens and a right lens of 3-D shutter glasses in accordance with the selected one of the first synchronization signal and the second synchronization signal.
