Page 25 Video upscaling A process to improve the picture quality from the original Upscaling is creating extra lines of pixels by copying parts of surrounding pixels In reality, upscaling circuits are ″guessing″ at what the image should look like at a higher resolution If done badly, it can ruin picture quality If done well, with high computing power it is an improvement Please note: Large LCD or plasma panels are needed to be able to enjoy any improvements Upscaling to even 1080p will NOT give high definition

Page 27 Upscaling Conclusions about upscaling: 1.Upscaling will NOT give you high-definition quality 2.To see any improvements, you must have a very good (min. HD Ready), large TV display 3.Very few TVs sold can handle 1080p or 1080/24p 4.720p might be better than 1080i (fast movements) 5.Upscaling CAN improve the picture quality, but not always

© 2008 Harman International Industries, Incorporated. All rights reserved. Page 46 New HDMI guidelines from October 17. 2008 HDMI Forum: ″HDMI version numbers, e.g., HDMI 1.3, can no longer be referenced in marketing materials unless the manufacturer also lists the specific HDMI features that are supported.″ HDMI Forum: ″HDMI-related features must be referenced using consistent naming conventions, e.g., Deep Color or x.v.Color, rather than by the use of manufacturer-specific brand names. In order to claim the feature, the manufacturer must demonstrate a minimum level of functionality.″ HDMI Forum: ″HDMI cables that have been tested to a higher performance standard (defined as 'Category 2' in the HDMI standard) are to be labeled 'High-Speed HDMI' cables. A High-Speed HDMI cable has been tested to reliably send a 1080p signal for 7.5 meters or more.″
