Patent ID: 8749614

Claim:
A method comprising: receiving a signal that includes content and signaling information configuring a program guide for the content at a receiving unit; decoding the signaling information from the signal; displaying the program guide with a perceived three-dimensional (3D) indicator on a screen of a display unit, wherein the perceived 3D indicator is displayed, by an on screen display (OSD) generator, on both a preview window and an item in the displayed program guide simultaneously, and the perceived 3D indicator identifies that the item corresponds to a perceived 3D content; decoding, at a decoder, content selected from the displayed program guide; displaying, on the display unit, the decoded content with a channel browser having the perceived 3D indicator on the screen, wherein the 3D indicator is a perceived 3D image; and when attribute information indicating whether the content includes 3D image data or not is not included in the signaling information, determining whether or not the content includes 3D image data by comparing a difference between blocks or pixels included in a single frame of image data forming the content with a determination threshold value, and wherein the comparing is referenced by an equation ∫Σ(m−m′)=k<ε)(ε is a 3D determination threshold value), where the k is a sum of Euclidean distances between points m of left image data and points m′ of right image data.
