HDMI cables support a data transfer rate of 5Gbps up to 30 meters and can handle a 1080p video and an 8-channel audio signal. And since a 1080p video and an 8-channel audio signal requires less than 4GB/s, the HDMI cable has a lot of headroom. This allows it to connect the DVD player, receiver and PRR separately with one cable.
　　In addition, HDMI supports EDID, DDC2B, so devices with HDMI have the characteristics of "plug and play", the signal source and display device will automatically carry out "negotiation" between the most appropriate video / audio format automatically selected.

　　HDMI has the advantages of small size, high transmission rate, wide transmission bandwidth, good compatibility, and can simultaneously transmit uncompressed audio and video signals. Compared with the traditional all-analog interface, HDMI not only increases the convenience of indirect wiring between devices, but also provides some HDMI-specific intelligent features.
