Identifier GUID-ED20F234-C5C4-4103-926C-774E57821BF4 Status Released Technology and components This chapter details the technology and components available in the system. Topics: • HDMI 1.4 • USB features Identifier GUID-F015869F-9930-4CD6-A002-678BC87259A3 Status Released HDMI 1.4 This topic explains the HDMI 1.4 and its features along with the advantages. HDMI (High-Definition Multimedia Interface) is an industry-supported, uncompressed, all-digital audio/video interface.
Advantages of HDMI • Quality HDMI transfers uncompressed digital audio and video for the highest, crispest image quality. • Low -cost HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-effective manner •...
Speed Currently, there are 3 speed modes defined by the latest USB 3.0/USB 3.1 Gen 1 specification. They are Super-Speed, Hi-Speed and Full- Speed. The new SuperSpeed mode has a transfer rate of 4.8Gbps. While the specification retains Hi-Speed, and Full-Speed USB mode, commonly known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps and 12Mbps respectively and are kept to maintain backward compatibility.
• USB 3.0/USB 3.1 Gen 1 RAIDs • Optical Media Drives • Multimedia Devices • Networking • USB 3.0/USB 3.1 Gen 1 Adapter Cards & Hubs Compatibility The good news is that USB 3.0/USB 3.1 Gen 1 has been carefully planned from the start to peacefully co-exist with USB 2.0. First of all, while USB 3.0/USB 3.1 Gen 1 specifies new physical connections and thus new cables to take advantage of the higher speed capability of the new protocol, the connector itself remains the same rectangular shape with the four USB 2.0 contacts in the exact same location as before.
