Not so with digital. It's all about bandwidth, chip sets, firmware, and transport streams. Keeping up with the latest digital interconnections is a full-time job. HDMI is the preferred way to convey uncompressed A/V data between devices such as Blu-ray Disc players, receivers, and HDTVs. And HDMI is attractive because one cable can carry high-definition video and up to eight channels of audio, and HDMI-linked devices can be designed to control one another. HDMI is also "universal" because, for example, it's agnostic with respect to ATSC (North America) and DVB-T (Europe and elsewhere) digital television standards, conveying both equally well. HDMI is also backward compatible with DVI digital video signals, and it uses HDCP copy protection. Great stuff. And pretty simple again, right? Not really.
