Wireless video transmitter and receiver

Types of Wireless Video Transmitters and Receivers

• HDMI Transmitters:

  This transmitter sends a video and audio signal through an HDMI cable. It will send a signal to a receiver that can also be seen through an HDMI cable. This kind of transmitter can be used to send video signals from devices like Blu-ray players, game consoles, and cable boxes straight to a TV or monitor without cables. This apparatus is useful in situations like wireless home theater systems or gaming setups where people want to link devices that are similar to each other and also link them to different displays.

• CCTV Transmitters:

  This kind of transmitter is used in security systems. It sends signals from a camera to a recorder or monitor so that people can keep an eye on an area remotely. These transmitters help enhance security by allowing real-time monitoring and recording of CCTV footage without using cables. Users can keep track of what's happening in monitored locations and store footage for review later. This technology helps boost security and makes it easy to check on camera feeds without cables.

• AV Transmitters:

  These are audio-visual transmitters. They can send signals that have both video and audio to a receiver. This allows people to stream content from one device to another without cables. For example, someone could send a video and sound from a computer to a TV using an AV transmitter. This lets people watch online videos or listen to songs on a bigger screen with no wires connecting the two devices. The streaming for this equipment is similar to how cable wires connect the audio and video between devices. So, users can enjoy movies, shows, and music from one device to another where the cables are connected.

• Long-Range Transmitters:

  Some applications require long-range wireless transmission, such as drone piloting, monitoring remote sensors, or industrial inspections. Long-range video transmitters can send signals over several kilometers (miles) to keep eyes on hard-to-reach locations. This equipment may use specialized antennas and transmission techniques to achieve extended range while still providing reliable video links. Users are able to monitor remote areas and control systems wirelessly over long distances.

• FPV (First Person View) Gear:

  FPV equipment is for drone flying or remote viewing. It usually consists of a small camera, video transmitter, and receiver or goggles. The setup allows operators to see what the drone or camera is seeing from that location. This is very nice for drone racing, inspections, or getting views from hard-to-reach places.

• Audiovisual Receivers:

  For receiver devices, there are AV receivers that receive a wireless signal and output it to a display or speakers. Receivers and display devices can also include projectors that receive video to project it, monitors that show the received video, or sound systems that play the audio. These work together to let users enjoy the transmitted audiovisual content at the receiving end without cables between the two. Receivers are key for making this wireless AV transmission to reception work.

Functions and features of wireless video transmitter and receiver

Various attributes define the functions of a wireless video transmitter and receiver. Below, find a table that summarizes these features and their corresponding functions:

• Resolution: The quality or resolution of a video transmitter should be decent, at least 720p HD. However, high-models can go up to 4K. This good resolution ensures there is no loss of clarity or delay in the transmission of the video, particularly for applications that are sensitive to such things, like video surveillance or industrial inspection.
• Low Latency Transmission: Homebodies, gamers, and those in the professional AV industry might be interested in the latency level when it comes to video transmission. They will need it to be as low as possible for real-time applications like live broadcasting or drone piloting.
• Transmission range: The transmission range of a video transmitter should be broad enough. It should not be limited, especially for long-distance applications like drone FPV, surveillance, or outdoor sports. Generally, the range should be anywhere between a few meters to several kilometers, depending on the model and environmental conditions.
• Wireless Protocol: The wireless protocol determines compatibility with other devices and transmission performance. A video transmitter and receiver can use WiFi, Bluetooth, or any other proprietary protocol. Each has advantages for a specific application.
• Multipoint Distribution: This feature allows more than one receiver to obtain the same video signal simultaneously from a single transmitter. It is helpful for applications where multiple people or devices need to access the same video feed, like drone racing.
• HDMI Input/Output: A video receiver with hdmi output is compatible with various devices like monitors, DVD players, and laptops. This compatibility allows the user to display or record high-definition video. On the other hand, a transmitter with an HDMI input will be able to send HD video from any source device that has an HDMI output to a receiving device that also has an HDMI input.
• OSI Layer 4-7: OSI’s Layer 4 (Transport layer) and Layer 7 (Application layer) are considered the transport and application layers in this context. They play a key role in ensuring reliable video transmission over IP networks. Layer 4 is responsible for establishing reliable transmission between two networked computers while also ensuring that data packets arrive in the correct order without errors and are acknowledged or retransmitted if they are not received. On the other hand, Layer 7 contains protocols used by applications like RTP, which is what carries the video, and RTSP, which helps control playback of that media.
