METHOD AND APPARATUS FOR MAKING INTELLIGENT USE OF ACTIVE SPACE IN FRAME PACKING FORMAT

摘要

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.

1. A method, comprising:
providing a video stream having a left active video frame and a right active video frame separated by an active space; providing data in the active space, wherein the data comprises a unique device identifier that identifies a particular video rendering device providing the video stream; and inferring a position of the left active video frame and a position of the right active video frame by detection of data in the active space.
