3D image signal transmission method, 3D image display apparatus and signal processing method therein

A method comprising:

• encoding, by a video encoder, video signals containing a plurality of video streams based on respectively different image viewpoints that support stereoscopic or 3D digital video images,
• said encoded video signals comprising a first parameter and a second parameter to be used in addressing potential stereoscopic window violations with respect to displaying of stereoscopic or 3D digital video images;
• and
• transmitting, by a transmitter to a receiver, the encoded video signals to be decoded at the receiver using the first and second parameters identified from the decoded video signals to support the displaying of stereoscopic or 3D digital video images with minimal stereoscopic window violations,
• wherein the stereoscopic window violations are suppressed by using floating window information, which includes a size of the floating window, added into a header extension for a video elementary stream (ES) among the plurality of video streams,
• wherein the size of the floating window is determined based on a position difference between an object in a right image and a corresponding object included in a left image, and
• wherein the header extension includes at least one field indicating the number or coordinates of a first luminance sample and a last luminance sample to identify the size of the floating window.

An apparatus comprising:

• a tuner for receiving encoded video signals containing a plurality of video streams based on respectively different image viewpoints that support stereoscopic or 3D digital video broadcasting services;
• a video decoder for decoding the received video signals and identifying a first parameter and a second parameter from the decoded video signals to be used in addressing potential stereoscopic window violations with respect to displaying of stereoscopic or 3D digital video images;
• and
• a controller for processing the decoded video signals using the identified first and second parameters to support the displaying of stereoscopic or 3D digital video images with minimal stereoscopic window violations,
• wherein the stereoscopic window violations are suppressed by using floating window information, which includes a size of the floating window, added into a header extension for a video elementary stream (ES) among the plurality of video streams,
• wherein the size of the floating window is determined based on a position difference between an object in a right image and a corresponding object included in a left image, and
• wherein the header extension includes at least one field indicating the number or coordinates of a first luminance sample and a last luminance sample to identify the size of the floating window.
