| Summary: | 碩士 === 國立中興大學 === 電機工程學系所 === 102 === In the present age of high-resolution digital video, High-Definition Multimedia Interface (HDMI) terminals are prevalent. HDMI terminal transmissions minimize analog and digital conversion times; thus, extremely detailed high-definition (HD) digital videos are now available for consumers, rendering brand new media experiences possible. From the early stages of digital television broadcasts to the recent Blu-ray Disc technology, HDMI terminals are used for transmitting HD digital television programs to viewers. The resolutions of images range from 720p, 1080i, to 1080p, displaying images with excellent quality. Therefore, such signals must be matched with high-level digital visual monitors, such as liquid-crystal-display televisions, plasma display panels, or projectors. The HDMI analyzer proposed in this study was developed to solve problems regarding matching source signals and monitors.
Chapter 1 of this study explains the research motivation. In the literature review, HDMI-related regulations, the systematic structure of the HDMI analyzer, and the framework of this study are discussed.
Chapter 2 presents the hardware equipment used in this study. The prototype was VA-1831, the function of which was fulfilled using the HDMI analyzer and the designed interface software. In addition, this chapter introduces the source signals of PG-505 and Xbox 360, which were used in this study.
Chapter 3 describes the development platform used in this study, the packet contents of the signals the HDMI analyzer received, and how this information was utilized, including Auxiliary Video Information InfoFrame, Source Product Description InfoFrame, Audio InfoFrame, or Moving Picture Experts Group InfoFrame.
Chapter 4 introduces the interface and operation of the developed software and the measured results of the PG-505 HDMI Deep Color & full 3D Pattern Generator (PG-505) and Xbox 360. The defects of the HDMI analyzer and the software developed in this study were tested using source signal adjustment.
Chapter 5 concludes this study and provides directions for future improvement.
