1. A video transcoder comprising:
a descrambling module that descrambles a 3D video signal based on scrambling data; a deformatting module, coupled to the descrambling module, that generates a deformatted video signal by unwrapping the 3D video signal in a source stereoscopic video format, based on device data that corresponds to a particular target device, to extract right and left picture views from the 3D video signal; a scaling module, coupled to the deformatting module, that downscales the right and left picture views from a source resolution and frame rate into a scaled video signal having a target resolution and frame rate of the particular target device; a reformatting module, coupled to the scaling module, that generates a reformatted video signal in accordance with a target video format by re-wrapping the scaled video signal, based on the scaled video signal and further based on the device data, wherein the target video format is one of: a stereoscopic frame sequential video format; and a stereoscopic frame composite video format; and a scrambling module, coupled to the reformatting module, that scrambles the reformatted video signal based on scrambling data prior to sending the reformatted video signal to the particular target device. |
