1. HDMI can not only meet the highest resolution of 1080P, but also support the most advanced digital audio formats such as DVD Audio. It supports eight-channel 96kHz or stereo 192kHz digital audio transmission, and only uses one HDMI cable to connect, eliminating the need for digital audio wiring.
2. At the same time, the additional space provided by the HDMI standard can be used in future upgraded audio and video formats, which is enough to handle a 1080p video and an 8-channel audio signal.
3. Since a 1080p video and an 8-channel audio signal require less than 4GB/s, HDMI still has a lot of margin. This allows it to be connected separately to the DVD player, receiver and PRR with one cable.
4. In addition, HDMI supports EDID and DDC2B, so devices with HDMI have the characteristics of "plug and play". There will be automatic "negotiation" between the signal source and the display device to automatically select the most appropriate video/audio format.
