  What is the impact of HDMI linear performance enhancement on home AV delivery? HDMI CEC - Electronic Control Function Looking back at HDMI version 1.0, when the HDMI cable connected to the theater equipment, the use of each machine needs to be individually manipulated, the whole process down, quite a hassle. So in order to simplify the control, when HDMI was upgraded to version 1.2a, a new feature was added - CEC, which requires only one person remote control, can control all the machines that support the CEC function, and no longer need to use multiple remote controls. As a straightforward example, a CEC-enabled player, amplifier, TV, sound wall, etc. can be connected so that when the machine is turned off, all systems can be turned off by simply pressing the power button on the TV's remote control, eliminating the need to turn off the player or sound wall individually. This “convenience feature” is seldom identified separately, because devices that support HDMI ARC and HDMI eARC functions all support CEC downstream.   2 HDMI ARC - Audio Return Channel In the traditional connection, the transmission of audio and video signals is usually like this: TV boxes, players and other output devices, connected to the amplifier via HDMI. Then the amplifier separates the video and digital audio signals, the video signal is transmitted to the TV through HDMI, the digital audio signal is decoded through the amplifier, the audio output sound.   This looks like nothing wrong, but when the TV needs to transmit sound, the trouble comes. After all, we are in the era of smart TV, TV through the network way to get the source, can be seen as playing local sources. The ordinary HDMI interface, not as a signal source to transmit signals to the outside world; if you want to connect the amplifier or audio, only through the fiber optic, coaxial interface connec

• How to choose the right length of DP HD cable ？ 2024-12-04

  How to choose the right length of DP HD cable ？ Distance between devices: Measure the actual distance between the source device (e.g., computer, game console) and the display device (e.g., monitor, projector). This is the basis for determining the length of cable required. Make sure to leave some margin so that you have the flexibility to adjust the position when cabling. Installation environment: Consider the path the cable will take, including any corners, obstacles or areas that need to be bypassed. areas that need to be bypassed. This may affect the total length required, as the cable may need to be longer to ensure smooth wiring without causing damage. Future Expandability: If you anticipate moving equipment or adding new displays in the future, choosing a slightly longer cable can facilitate future adjustments and avoid having to purchase new cables. Signal quality: While DP cables support longer distance transmission (up to 15 meters), cables that are too long may affect signal quality due to increased resistance, capacitance and inductance. Therefore, it is important to consider the quality standards of the cable while meeting the length requirements to ensure stable signal transmission. Budget and Cost Effectiveness: Longer cables are usually more expensive, so it is important to control the cost reasonably while meeting the demand. 4k Displayport Cable, 

• About USB interface type sharing 2024-12-03

  USB (Universal Serial Bus) is a data communication interface standard widely used in computers and mobile devices. Since its joint development in 1995 by Intel, Compaq, Digital, IBM, Microsoft, NEC and Northern Telecom, the USB interface has evolved into an industry standard and is still evolving. I. USB Interface Types USB interface types are mainly categorized according to their physical form, which can be roughly divided into three categories: USB Type-A, USB Type-B and USB Type-C, USB 3.2 CABLE each of which can be further subdivided according to size. ? 1、USB Type-A ? Standard Type-A: This is the most common USB interface, usually used for devices such as mice, keyboards and USB flash drives on computers. ? Mini Type-A: a miniaturized Type-A interface, now less used. ? Micro Type-A: a smaller Type-A interface, also has been gradually eliminated. ? 2、USB Type-B ? Standard Type-B: This interface is commonly used in printers and devices such as monitors with touch and USB ports. ? Mini Type-B: A miniaturized Type-B interface, less common now. ? Micro Type-B: commonly known as Micro USB interface, commonly used in early Android phones and mobile power and other devices.Micro USB 2.0 and Micro USB 3.0 in the appearance of a slight difference, but Micro USB 2.0 cable can be inserted into the Micro USB 3.0 interface, and vice versa. ? 3、USB Type-C ? Type-C: This is currently the most popular USB interface, support for both positive and negative insertion, widely used in smart phones, tablets and some laptops and other devices. type-C interface not only supports charging and data transmission, but also can be used as a video output interface, so there is a “fu
