• HDMI supports communication between the video source (such as a DVD player) and the DTV, enabling new functionalityUSB featuresUniversal Serial Bus, or USB, was introduced in 1996. It dramatically simplified the connection between host computers and peripheraldevices like mice, keyboards, external drivers, and printers.Let's take a quick look on the USB evolution referencing to the table below.Table 1. USB evolutionType Data Transfer Rate Category Introduction YearUSB 2.0 480 Mbps High Speed 2000USB 3.0/USB 3.1 Gen 1 5 Gbps Super Speed 2010USB 3.1 Gen 2 10 Gbps Super Speed 2013USB 3.0/USB 3.1 Gen 1 (SuperSpeed USB)For years, the USB 2.0 has been firmly entrenched as the de facto interface standard in the PC world with about 6 billion devices sold, andyet the need for more speed grows by ever faster computing hardware and ever greater bandwidth demands. The USB 3.0/USB 3.1 Gen 1finally has the answer to the consumers' demands with a theoretically 10 times faster than its predecessor. In a nutshell, USB 3.1 Gen 1features are as follows:• Higher transfer rates (up to 5 Gbps)• Increased maximum bus power and increased device current draw to better accommodate power-hungry devices• New power management features• Full-duplex data transfers and support for new transfer types• Backward USB 2.0 compatibility• New connectors and cableThe topics below cover some of the most commonly asked questions regarding USB 3.0/USB 3.1 Gen 1.SpeedCurrently, 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 tomaintain backward compatibility.USB 3.0/USB 3.1 Gen 1 achieves the much higher performance by the technical changes below:• An additional physical bus that is added in parallel with the existing USB 2.0 bus (refer to the picture below).• USB 2.0 previously had four wires (power, ground, and a pair for differential data); USB 3.0/USB 3.1 Gen 1 adds four more for two pairsof differential signals (receive and transmit) for a combined total of eight connections in the connectors and cabling.• USB 3.0/USB 3.1 Gen 1 utilizes the bidirectional data interface, rather than USB 2.0's half-duplex arrangement. This gives a 10-foldincrease in theoretical bandwidth.8 Technology and components
