Signal identification for downstream processing

摘要

A signal identification process as contemplated to facilitate output of signaling based at least in part on metadata transmitted with the signaling. The contemplated processing may include facilitating output of the content according to one of a plurality of output modes depending on the metadata specifying values for a dynamic floating window (DFW) field and a 2K format conversion preference field.

1. A method of processing 3D signaling for output as 3D content, the 3D signaling including a plurality of left-eye and right-eye images, the method comprising:
determining horizontal image translation (HIT) performed on the 3D signaling prior to being transmitted as HIT-formatted 3D signaling to a device for output, including determining a dynamic floating window (DFW) added to each of at least one of the left-eye and right-eye images; associating metadata with the HIT-formatted 3D signaling according to the HIT performed, the metadata sufficient for use with the device to facilitate automatically processing the HIT-formatted 3D signaling for output, the metadata including a DFW field set to: i) a first value when identifying the HIT-formatted 3D signaling for output according to a preservation mode; and ii) a second value when identifying the HIT-formatted 3D signaling for output according to an expansion mode; determining the HIT to be in a symmetrical manner to produce the HIT-formatted 3D signaling, the symmetrical manner including: i) shifting of each left-eye image in a first direction by a first amount of pixels such that a first portion of each left-eye image is cropped; ii) shifting of each right-eye image in a second direction opposite to the first direction by the first amount of pixels such that a second portion of each right-eye image is cropped; iii) adding of the DFW to a third portion of each left-eye image, the third portion being opposite to the first portion, the DFW replacing corresponding pixels of each left-eye image with black bars; and iv) adding of the DFW to a fourth portion of each right-eye image, the fourth portion being opposite to the second portion, the DFW replacing corresponding pixels of each right-eye image with black bars.
