Wireless hdmi transmitter 2 receiver

Types of Wireless HDMI Transmitters

A wireless HDMI transmitter marked “2 receiver” is a device that can send signals from an HDMI source to two receivers. Receivers can be either wireless or wired depending on the model. The following are some of the common types of wireless HDMI transmitters designed for two receivers:

• Dual Band Transmitter

  A dual-band transmitter can send signals on two frequency bands. The bands are 5GHz and 2.4GHz. Each band has unique advantages. For example, a 2.4GHz band can transmit signals over a longer distance compared to the 5GHz band. However, the 5GHz band can pass through obstacles like walls, trees, and floors better than the 2.4GHz band. The ability to transmit on two bands gives users flexibility. They can choose a band that best suits their needs in a particular situation.

• Dual Link Transmitter

  This kind of transmitter has two physical ports to connect two independent receivers (usually displays). The second output can serve as a backup in case the primary port fails. It can also be used to extend the desktop by displaying additional monitors for multitasking or to clone it in order to share presentations or lectures.

• Transmitter with Two Receiver Units

  This kind of transmitter comes with two receiver units. Users will not have to buy an additional receiver unit, after selling the main transmitter unit. This kind of unit is useful for people who want to connect two separate displays in different locations.

• Multi-Input Transmitter

  Some transmitters come with a number of input ports. They have HDMI switch capabilities which allow users to connect various sources like game consoles, cable boxes, streaming devices, and Blu-ray players - all at once. Then users can easily switch between the sources that they want to view on their two displays. This kind of transmitter enhances entertainment and multimedia setups.

• Transmitter with Extended Range

  Transmitter models with extended or long-range capacity can send signals over longer distances to two independent receiver units. Long-range models can transmit signals about 300 feet to receivers even in locations with obstacles or in areas with limited line of sight. These models are ideal for users whose receivers are far away from the source device. Improved range allows users to place their receivers in convenient locations.

Functions and features of wireless HDMI transmitters and receivers

The rather ingenious technique used by wireless HDMI transmitters is to provide a cable-free option for streaming media to a high-definition display. This is accomplished by the transmitter sending the signal over a wireless connection to a receiver, which is then connected to the display device. The signals are usually sent via Wi-Fi, and the transmitter is connected to the media source either by cable or integrated with a streaming device or as a dongle.

Advantages of Wireless HDMI Include:

• No cable clutter
• No need for long cable runs
• Flexibility in system design and layout

Types of Wireless HDMI Transmissions Include:

Different standards and technologies are available for transmitting the HDMI signal wirelessly, each of which possesses unique features:

• Wi-Fi: Some wireless HDMI systems use standard Wi-Fi networks to transmit the video and audio, which can provide higher quality and transmission range. Examples of wireless HDMI technologies include Miracast, Wi-Fi Direct and Chromecast.
• Bluetooth: Wireless HDMI devices sometimes use Bluetooth technology for audio transmission, but it has limited capability compared to Wi-Fi.
• Proprietary: Some wireless HDMI products use proprietary technology for transmission, like Dual-band 5Ghz and 2.4GHz Wi-Fi, which provides flexibility to the user.
• HDMI cable length: Although an HDMI cable can transmit signals up to 50 meters without significant loss, the maximum length of an HDMI cable without loss depends on the cable quality, the equipment, and environmental factors. If long runs are required, consider using wireless transmission.
• Power Line: Wireless HDMI can use existing power lines in the home to transmit signals.

The range of wireless HDMI devices can vary from 30 feet (10 meters) to over 100 feet (30 meters) without loss or interference, depending on the model and environment. The transmitter and receiver should be in line of sight, although cables can be run between them. Obstacles like walls, furniture, or other wireless devices can cause interference or signal loss.

Wireless HDMI can bring long cable runs without interference and cable-cluttered systems, but it is essential to choose the right one for the application, and its strengths and weaknesses are understood. The device's range, audio and video quality, budget, and convenience are critical factors.

Scenarios

A wireless HDMI transmitter and receiver are versatile devices that can be used in many settings. Here are some common usage scenarios:

• Home Entertainment

  A transmitter can be connected to a game console in one room. Receivers let users view gameplay on a TV in another room without cables. This setup allows gaming, streaming, or viewing media all done wirelessly.

• Office Presentations

  Wireless HDMI transmitters are useful in meeting rooms or classrooms. They allow seamless content sharing from laptops or tablets to a large display for effective presentations and collaborating without messy cords.

• Digital Signage

  Businesses often use HDMI wireless transmitters and receivers for digital signage applications. A transmitter can send marketing content from a media player to multiple receiver units connected to monitors in different areas of a store or restaurant. This allows business owners to display consistent advertising across several screens without requiring HDMI cables.

• Outdoor Parties or Events

  When organizing an event, one can link a laptop with multimedia content to a projector using a wireless HDMI transmitter. This enables transportable projecting of presentations, slideshows, or videos for audiences, showcasing entertainment found on the internet or television.

• Multi-Room Streaming

  Cable-cluttered zones can be liberated by transmitting devices, allowing users to connect HDMI sources to TVs or displays placed in diverse rooms throughout a residence without employing cables.

• Gaming Consoles

  Enabling high-definition gameplay streaming onto different monitors or TVs for gaming enthusiasts. This wired alternative offers better performance and lower latency for a more immersive experience.

How to Choose Wireless HDMI Transmitters and Receivers

Because customers worry more about video quality than they do about wired transmission, merchants must choose wireless HDMI equipment with good video quality. Theoretically, HDMI can provide 4K resolution, but only in a short, direct line without interference. Long-range wireless transmission of 4K video is challenging because of the high bitrate and signal attenuation. Hence, consumers concerned about wireless transmission will often settle for 1080p.

Whether a 4K/1080p can be played depends on the decoding capability of the receiver. If the 4K transmitter is not encoded in a form the 4K UHD TV can decode, the 4K pan will be useless. The latency of 1080p and 4K is different. For lower resolutions, the latency is lesser, and the receiver can decode faster. However, for higher resolution, latency is higher, and games will be useless. For gamer-merchant, low latency is important for good game performance.

Consider how far away the signal can be received from the transmitter. 2.0 can only be used in a line of sight, but the 1.4a version can be used in a non-line-of-sight condition. The distance in a non-line-of-sight condition is shorter. 64 feet is good enough to work inside a house, but if the system is used in an open-air condition without any obstacles, it can achieve up to 328 feet.

Versions 1.4a and 2.0 are compatible. If a device cannot transmit more than 1.080p/60Hz, it will still be able to receive from version 1.4a but only up to 1.080p/60Hz. Wireless devices are subject to interference from different devices like a microwave oven, LAN, cordless phone, and Bluetooth. Version 1.4a is less susceptible to interference because it can send HDMI up to 100 feet on a CAT-5 cable if there are interference issues. Merchants should stock the device which can do a cable transmission to avoid bad wireless transmission.

Merchants should buy devices that can do firmware updates. There are two installments, the dongle type and the box type. The box type is easier to upgrade as it has a USB port. The dongle type is more challenging to upgrade because it is more challenging to open the device.
