How Does HDMI Compare to Component?
High Definition Basics In the world of HD media, there are several basic facets of this visual technology you must keep in mind when considering component cables versus HDMI cables. First of all, there are five different standardized “grades” of HD picture: 480i, 480p, 780p 1080i and 1080p. The number in these grades refers to the maximum lines of horizontal resolution, and the letter refers to whether the display is progressive or interlaced. Interlaced scanning is older and uses an analog-inspired format, while progressive is purely digital and displays the picture at a much faster rate. Component Cables Component cables have an analog-style delivery method, similar to the traditional triple-pronged cables of the last media generation. Component cables work by splitting up the different color and audio signals and then putting all these components back together onscreen. This is why they are optimized for interlaced displays, since they both use primarily analog technology. Component
