Abstract
Active Space separates the Left Frame from the Right Frame in a frame packing format. A source device is expected to transmit a constant pixel value. A sink device is expected to ignore all data received during the Active space regardless of the value. Embodiments of the present invention involve the Source device to embed intelligent information in the Active Space in lieu of the recommended fixed pixel value. Then the Sink device may read the embedded information from the Active Space, and infer the transition between the left frame and the right frame which is useful, for example, to synchronize eyewear.
