Abstract:
1. A method of transmitting video data via a digital data interface, the method comprising: inserting three-dimensional (3D) video data into a video data period in a video frame; inserting information regarding a 3D image format of the 3D video data into a data island period in the video frame; inserting information indicating whether the information regarding the 3D image format is inserted into the data island period, the information indicating whether the information regarding the 3D image format is inserted into the data island period, comprising a first value indicating that there is no additional video format and a second value indicating that the information regarding the 3D image format is inserted; and transmitting the video frame via the digital data interface, wherein the 3D image format represents a structure of left-view data and right-view data of the 3D video data aligned in one 3D image, wherein the 3D image format of the 3D video data comprises a top-and-bottom format, wherein the inserting the information regarding the 3D image format comprises inserting information regarding a sub-sampling method for the top-and-bottom format into the data island period in the video frame, the sub-sampling method for the top-and-bottom format is a sub-sampling method of respectively aligning the left-view data and the right-view data having halves of resolutions of a left-view image and a right-view image of the 3D video data, in a top region and a bottom region of a 3D image in the top-and-bottom format, wherein information regarding the top-and-bottom format is inserted into a reserved period of a 3D video data field in a vendor-specific infoframe in the data island period, and the information regarding the sub-sampling method for the top-and-bottom format is inserted into a reserved period of an extended 3D video data field in the vendor-specific infoframe.
