64:33 528x576 16:9 frame without horizontal overscan 160:99 528x480 16:9 frame without horizontal overscan 1440x1080 16:9 frame without horizontal overscan 1280x1080 16:9 frame without horizontal overscan 960x1080 16:9 frame without horizontal overscan 17..254 Reserved Extended SAR NOTE 1 - For the examples in Table E-1, the term "without horizontal overscan" refers to display processes in which the display area matches the area of the cropped decoded pictures and the term "with horizontal overscan" refers to display processes in which some parts near the left and/or right border of the cropped decoded pictures are not visible in the display area. As an example, the entry "720x576 4:3 frame with horizontal overscan" for aspect ratio equal to 2 refers to having an area of 704x576 luma samples (which has an aspect ratio of 4:3) of the cropped decoded frame (720x576 luma samples) that is visible in the display area. sar_width indicates the horizontal size of the sample aspect ratio (in arbitrary units). sar_height indicates the vertical size of the sample aspect ratio (in the same arbitrary units as sar_width). sar_width and sar height shall be relatively prime or equal to 0. When aspect_ratio_idc is equal to 0 or sar_width is equal to 0 or sar_height is equal to 0, the sample aspect ratio shall be considered unspecified by this Recommendation International Standard. overscan_info_present_flag equal to 1 specifies that the overscan_appropriate_flag is present. When overscan_info_present_flag is equal to 0 or is not present, the preferred display method for the video signal is unspecified. Rec. ITU-T H.264 (01/2012) overscan_appropriate_flag equal to 1 indicates that the cropped decoded pictures output are suitable for display using overscan. overscan appropriate equal to 0 indicates that the cropped decoded pictures output contain visually important information in the entire region out to the edges of the cropping rectangle of the picture, such that the cropped decoded pictures output should not be displayed using o
