E.D.I.D Extended Display Identification Data TV`s have built into
E.D.I.D Extended Display Identification Data TV’s have built into them various Audio and Video Capabilities Here we can see that this TV can accept many video formats including 480p, 720p, 1080p etc and in a variety of aspect Ratio’s Extended Display Identification Data Here We Can See The Various Audio Formats That This TV Supports These include PCM, AC3, DTS and Various Frequencies E.D.I.D Stands For Extended Display Identification Data When Products Like These Start Up ? ? The Source product will request from the TV what formats it can accept. The TV will respond with a manufacturer identifier and capability information. The Source device will then set the Video and Audio up accordingly. E.D.I.D Stands For Extended Display Identification Data This is all fine when the source products are just talking to one TV When installers start to build HDMI networks, I.E. Sources “talking” to multiple TV’s via switchers or matrix products, it can get more complicated. There can be different TV brands with different capabilities in the network.
