HDMI and fiber difference: fiber can not transmit next generation audio track
When you need to connect your newly purchased SoundBar or AV receiver to your home theater device, you're bound to be connected to two main audio cables: HDMI and fiber. Perhaps for most users, HDMI is actually the easiest option, but if you understand the characteristics of fiber-optic audio cables, you might not simply choose the HDMI connection. In summary, both HDMI and fiber audio connections have their own advantages and disadvantages.
Both HDMI and fiber-optic audio cables are transmitted between devices and are more advanced than traditional red-and-white analog signal transmission and support multi-channel sound transmission like Dolby Digital Stereo. In addition, whether it is HDMI or fiber audio cable, the cost is very cheap.
The biggest difference between the two is that the HDMI audio cable can transmit higher quality sounds, including Blu-ray audio, Dolby TrueHD and DTS HD Master Audio audio encoding. Audio in these formats cannot be delivered on fiber optic cables. In addition, HDMI can also directly transmit video signals. So simply, if you want to pass everything through a cable, HDMI is the best choice.
However, depending on the different devices, HDMI is sometimes not the best choice. If your device has a certain age and you just need to connect a simple sound output device such as Sound Bar to the TV, then the fiber audio is Very good connection. In this case, sometimes it is the only option without worrying too much about HDMI. For most simple sound devices, fiber and HDMI are actually the same.
In one case, if you have a Sound Bar device that supports surround sound like the Sonos Playbar or Vizio S4251w-B, you can't connect directly to the TV via a fiber-optic cable. But usually these Sound Bars don't have an HDMI interface, so the best way is to connect the TV sound source directly to the Sound Bar and skip the TV.
But no matter which device you use, as described above, fiber-optic audio cables cannot transmit high-quality sound such as Dolby TrueHD or DTS HD Master Audio. However, the difference in sound quality between the two is not as obvious as you might think. Although HDMI can deliver better sound, we also need a certain quality of speaker and amplifier equipment to work together. The mere use of HDMI cables alone to improve quality is not obvious.
On the whole, the use of HDMI is not only cheap, but also can be used in multiple lines, while transmitting video and sound signals. However, if your old device does not support the HDMI interface, and your audio source is not as high as Blu-ray, then the fiber audio cable can also meet the demand. In addition, even if you use HDMI connection, but the quality of other devices has not kept up, then even the sound source such as Dolby TrueHD or DTS HD Master Audio, there will be no obvious improvement, home theater network WeChat: cnhifi.
An Outdoor CPE (Customer Premises Equipment) is a client device used in outdoor environments, typically for wireless network connectivity. It is a device used to transmit Internet signals from a service provider to the user's location.
Outdoor CPE is commonly used to provide broadband access services, especially in remote areas or places without traditional wired network coverage. It can transmit an Internet connection via wireless signals to the building or area where the user is located. Outdoor CPE is typically a highly protected and durable device designed to handle harsh weather conditions in an outdoor environment.
Outdoor Cpes typically include the following main components:
1. Antenna: Outdoor CPE is usually equipped with a high-gain antenna for receiving and sending wireless signals. These antennas can be designed for different frequency bands and wireless standards.
2. Wireless module: Outdoor CPE usually includes a wireless module to handle the transmission and reception of wireless signals. This module usually supports different wireless standards such as Wi-Fi, LTE, 4G, etc.
3. Router function: Outdoor CPE usually has the function of a router, which can distribute the Internet connection to the device where the user is. It can provide IP address allocation, port forwarding, network security and other functions in the local area network.
4. Power supply and battery: Since Outdoor CPE is usually used in outdoor environments, it usually requires a reliable power supply. Some Outdoor Cpes are also equipped with batteries to provide continuous Internet connectivity in the event of a power outage.
The main features and advantages of Outdoor CPE are as follows:
1. High-speed broadband access: Outdoor CPE can provide high-speed broadband access services through wireless signals, so that users can enjoy high-speed Internet connections in places without traditional wired network coverage.
2. Flexibility: Since Outdoor CPE is a wireless connection, it can be used in different locations and environments. Users can place the Outdoor CPE in the best position as needed for optimal signal coverage and performance.
3. Simple installation: Outdoor CPE usually has a simple installation process, and users only need to place the device outdoors and make some basic Settings to start using the Internet connection.
4. Strong anti-interference ability: Outdoor CPE usually has strong anti-interference ability and can provide stable Internet connection under harsh environmental conditions. It can cope with various sources of interference, such as electromagnetic interference, weather conditions and so on.
5. High reliability: Outdoor CPE usually has a high degree of reliability and durability, and can be operated for a long time in a variety of outdoor environments. It usually has waterproof, dustproof, lightning-proof and other functions to cope with different weather conditions.
Outdoor CPE is widely used in a variety of scenarios, especially in rural areas, mountains, islands and other places without traditional cable network coverage. It can provide high-speed broadband access services to residents and enterprises in these areas, helping them to enjoy the convenience of the Internet.
In summary, the Outdoor CPE is a client device for outdoor environments to provide high-speed broadband access services via wireless signals. It is highly reliable, flexible and anti-jamming, and can provide a stable Internet connection in a variety of outdoor environments. It plays an important role in providing broadband access services, especially in places without traditional wired network coverage.
