Advantages of using the HDMI audio interface
Through the existing audio interface, such as analog RCA connectors and digital SPDIF (coaxial and optical connectors) the advantages of using HDMI: 1, high: HDMI audio in digital form is much pure transfer to the amplifier. Due to the audio adjustment device connection and other electronic devices, analog audio connections easier loss. With respect to the SPDIF connection, HDMI has more bandwidth, can be allowed to support the latest lossless audio formats such as Dolby TrueHD and DTS-HS Master Audio. These formats can not connect to support SPDIF, because the data they require a very high rate, exceeding the SPDIF capability. See HDMI 1.3 section to learn more about Dolby TrueHD and DTS-HD Master Audio formats. 2. Ease of use: HDMI integrated video and multi-channel audio in a single cable, eliminating the current cost of A / V system using multiple cables, complexity and confusion. This is particularly useful when you upgrade or add equipment. 3, high intelligence: HDMI supports two-way communication between the audio source (such as a DVD player) and audio adjustment device (such as A / V receiver) conducted to support features such as automatic configuration and one-touch play new features. By using HDMI, the device will automatically connect the A / V receiver is the most efficient transmission formats (such as Dolby Digital and 2-channel PCM), so that consumers do not need to scroll through all the audio format options to guess what is the best and most support format.
