How to Avoid Distortion in A/V Transmitters

300 meter wireless HDMI TV sender


An audio / video transmitter, or AV transmitter, is a wireless device that sends audio and video signals from one device to another. The simplest explanation of how it works is to think of a TV signal, but on a far smaller scale. Instead of the TV station transmitting a signal to everyone who has a TV aerial, the transmitter sends a signal only to a specific receiver. Using this type of equipment allows one to send an audio/video signal from one device to another without needing to run a cable between rooms or equipment. Simply connect the transmitter to one device and the receiver to another.
As with all wireless signals, one can experience distortion or signal loss. This is aggravated by factors such as objects blocking the signal and a loss of line of sight. Loose connections, or poor signal can further complicate matters. Poor signal can be the result of issues like low quality hardware, damaged devices, or other faults. In order to minimize distortion one should shop carefully, doing adequate research through customer and expert reviews. Consumers must understand which specifications to look for in audio/video transmitters. AV transmitters are available from electronics stores or online.
Unfortunately, AV sender have not evolved to the level where they are readily compatible with HD devices. In addition, they are never completely wireless and need a main source of power to function. They have to be plugged in and switched on to work. While wireless technology is convenient and fast, coaxial cable connections give consistently better results. However, fixed cabling systems may be unsightly, more expensive, and impractical.

How Audio/Video Transmitters Work

Connecting a wireless AV sender to a TV, DVD player, or other AV device turns the device into a broadcaster of video and audio signals. Connecting an AV receiver to another device within range turns that device into a receiver that is able to decode the signal sent out by the transmitter. Audio and video signals can be transmitted throughout one's home and some AV transmitters even allow one to change channels from a distance. However, one may need a remote control extender for this function. Installation is usually simple. Antennas are normally built into the sending and receiving units and all that is required is connecting the cable to the correct jack or connection. AV signals are usually transmitted via wideband FM (frequency modulation) signals that may help minimize interference from other transmitters.
The best way to avoid distortion in wireless video transmitter is to choose the right sender based on specifications and reviews. Specifications include the frequency it broadcasts on, the range it covers, and the type of antenna the device has.

Broadcast Frequencies

Many AV transmitters broadcast signals in the 2.4 GHz frequency band. Unfortunately, this is also the band used by 802.11b and g Wi-Fi devices, as well as microwave ovens, cordless phones, and a number of other consumer electronics. These devices can cause interference, which leads to distortion and signal degradation. Transmitters that broadcast on a different frequency, like 5.8 GHz, are far less prone to distortion caused by interference.
Some transmitters feature adjustable frequencies (or channels) to allow users to find the best settings with the least amount of interference and distortion. The transmitter and receiver must be on the same channel for the set to work effectively. Where reception is poor or there is a large amount of interference one can adjust the channel to eliminate interference from other electrical devices. Some devices, like microwave ovens, may cause interference on all channels. If buying a transmitter that works on a higher frequency is out of the question, the simple solution to this problem is to use only one device at a time.

Broadcast Range and Signal

As with most wireless devices, AV transmitters rely on line of sight for clear, strong signals. One should always place the transmitter and receiver in open, uncluttered, unobstructed areas where the sender and receiver can "see" each other. In other words, the two devices should be in each other's line of sight. To better understand this, think of listening to the radio while driving. The moment one enters a tunnel or drives between high hills or mountains, the car's radio antenna loses line of sight with the radio station's sender and the signal cuts out or distorts.
Some transmitters are marked with the maximum range over which signals can be transmitted without obstructions between the sender and receiver. These are often somewhat optimistic, but can be used as a guideline for comparison nevertheless. Few homes are obstruction-free over the distances quoted by manufacturers, but some may wish to broadcast signals to rooms or areas outside the house. Some units are designed for outside use, with waterproof coverings and a more robust design. These transmitters boast range distances of up to 20 times that of indoor transmitters, but the range drops off significantly the moment an obstruction is encountered.

Antenna Types

The majority of transmitter types come with built-in antennas, but some transmitters feature adjustable antennas. These may need to be adjusted to find the best signal, or realigned to eliminate distortion. Where one is using more than one sender or receiver, antennas may need to adjusted every time one swaps between devices.

Using Customer and Expert Reviews to Choose an AV Transmitter

In addition to taking the factors above into consideration when choosing an av sender, one should also do research by reading customer and expert product reviews. Customer reviews should, in some cases, be taken with a grain of salt as people are more inclined to post about negative experiences than they are about positive ones. However, this can be read in conjunction with expert reviews to see how devices perform in real life situations, and how the features and benefits highlighted by manufacturers compare during day-to-day use.

How to make Cable to TV by Wirelessly connect

300m HDMI av sender

Wireless technology seems to be the norm for most electronics, so it is reasonable to think that cable TV should be wireless as well. By switching to wireless, you can move the television to anywhere in the room or to another room altogether and not feel chained to a single cable outlet. You can send cable signals wirelessly with ease by using a wireless RF transmitter. Follow the steps to position the television, connect the transmitter and receiver, and adjust the signal to enjoy wireless cable TV in your home.

Choose Optimal TV Placement

Before connecting cable, choose a spot in the room to install the TV. Even though the cable is wireless, the television still needs power to operate, so the wall outlet should be nearby. With a wireless connection, you do not have to worry about staying close to the cable outlet. When possible, place the television at eye level. If that is not possible, angle it down to make viewing easier. Avoid placing the television on a wall opposite of a large window.

Connect the Wireless Transmitter to the Cable Box or Outlet

Locate the cable outlet in the room. Connect the wireless audio/video transmitter directly to the wall outlet using a coaxial cable. If the home theater system uses a cable box, connect the wireless transmitter directly to the cable box. Attach the coaxial cable from the wall in the RF IN input of the cable box. Attach another coaxial cable to the RF OUT port on the cable box into the wireless transmitter. Plug the transmitter into a power outlet using the power adapter and turn it on. Adjust the antenna of the transmitter to point toward the television.

Connect the Wireless Receiver to the TV

Connect the wireless receiver to the proper port on the television. The most common way to connect the receiver is with red, yellow, and white RCA cables. Depending on the model of the receiver and the television's capabilities, you can also connect the receiver to the television using HDMI cables or coaxial cables. Plug the power adapter into a wall outlet and power the wireless receiver on. Adjust the television to the proper input when appropriate. Move the antenna to point in the direction of the wireless transmitter so it can effectively pick up the signal.

Adjust the Signal

Devices in the home, such as microwaves, cordless telephones, and security systems, can affect the wireless cable signal. Ensure that the wireless transmitter and receiver system operates on a different frequency than other devices to get the best signal. Typically, the system operates on a frequency of 2.4 GHz or 5.8 GHz. Some systems have adjustable frequencies so that you can create the best signal possible. Power the television and cable box on. Adjust the placement of the receiver until the TV has the clearest picture.

Install an IR Extender for the Remote Control

If you place the television across the room or in a different room altogether, then using the remote control to change the channel might prove problematic. In most instances, you need to point the remote directly at the device in order for it to function. If the cable box is hidden inside a cabinet or on the opposite side of the room, the remote might not work at all. Installing an IR extender allows you to place the cable box in an inconspicuous location and still control it. Simply plug the connector into the IR port of the cable box and then mount the IR extender in a position that is more favorable. Make sure no object blocks the sensor located on the front of the receiver.

How to Convert Cable TV to Wireless

Convert your cable TV to wireless

How to Convert Cable TV to Wireless

 

Hardwiring a television to a cable outlet seems antiquated when more and more electronics are moving toward wireless technology. Convert your cable TV to wireless by using a wireless RF transmitter and receiver ( wireless av transmitter and receiver fit for RCA port device, and HDMI av sender fit for HDMI port device ) to transmit signals from the cable box to the TV. This gives you the freedom to move a television to the other side of the room or house without having to move the outlet as well. By choosing the right equipment, connecting the wireless transmitter and receiver, and configuring the wireless signal, you can enjoy cable television free from wires.

1 - Choose Wireless Transmitter-Receiver Equipment
Several brands and models of wireless transmitters and receivers that deliver RF signals are available, and each model offers different features and capabilities. These systems work on frequencies that do not interfere with other devices in the home, such as microwaves and cordless telephones. They typically operate at frequencies of 2.4 GHz and 5.8 GHz. Choose one that operates at a frequency different than the frequency of other devices in your home to achieve a good signal and a clear picture.

While many wireless transmitters and receivers work for a single television, there are a handful that offer expandability options. To connect several televisions to a single cable outlet wirelessly, choose a system that has multiple receivers and a transmitter that can accommodate them.

2 - Connect the Wireless Transmitter to the Cable Box
The wireless transmitter connects directly to the wall outlet or the cable box. Connect the coaxial cable from the wall to the "RF IN" port on the transmitter. If you are connecting it to a cable box, connect a line from the "RF OUT" connector on the cable box to the "RF IN" port on the transmitter. Connect the AC adapter to the transmitter and plug it into a standard outlet. Power the device on and select the channel output.

3 - Connect the Wireless Receiver to the TV
The wireless receiver connects directly to the television using either an HDMI cable or a coaxial cable. Choose a short cable so that it is easy to conceal the receiver behind the television. Choose a longer cable to conceal the receiver inside an entertainment system.

Connect one end of the cable to the receiver and the other end to the appropriate HDMI or coaxial port on the television. Connect the AC adapter to the receiver and plug it into an outlet. Power the device on and select the channel output that matches the channel you selected on the transmitter. Repeat this process for all receivers.

4 - Set Up Your Television
When connecting an external device to a television, like a DVD player, VCR, or cable box, always plug them into the proper inputs. From the input menu on the screen, select the one that you connected the receiver to. If you use a coaxial connection, tune the television to the channel selected on the devices. For many televisions, this is channel 3. If you connect the receiver using an HDMI cable, tune the television to the appropriate HDMI input.

5 - Configure Your Wireless Signal
The transmitter and receiver each have a paddle or antenna that allows the two devices to communicate with each other. You may need to adjust the paddles on occasion to get a clearer signal. When first installing the system, point the paddles toward one another. After initial installation and turning on the television, make minor adjustments to the receiver until you obtain the clearest picture.

6 - Install the IR Remote Extender
If the television is in a different room and the cable outlet or box in another, install an IR remote extender so that you can use the standard remote. This boosts the IR sensitivity so that you do not have to worry about furniture or walls blocking the signal. Install the IR extender to the wireless transmitter and then place the receiver in an open area. Typical placement is near the IR receiver of the cable box. You can use the remote as normal to control the television.

How to Install your Wireless Cable TV

PAKITE 300 meter Wireless HDMI Transmitter Receiver

It seems that any home you visit has at least two smart devices. Now, smart technology has been integrated into everyday home appliances like the stove and refrigerator, but the most popular smart appliance today is the smart TV. These TVs are capable of doing anything from streaming videos to downloading apps, and they're a lot sleeker than they used to be. This is why so many smart TV owners mount their televisions.
When it comes to mounting, there isn't much one can do with bulky cable boxes other than hide them away. However, you can purchase a wireless cable box that will at least eliminate the need for cords. If you plan to buy one, here are a few easy setup instructions.

Connecting Your Wireless Cable TV Box

First, let's assume you're not going to place the wireless cable TV transmitter near the television itself. Start by moving your cable box to a place that has some space alongside it. Next, place the wireless cable TV transmitter next to it. Then connect the two boxes together using the HDMI cord supplied with either. The HDMI cord enables video and audio transmission from one source to the other. To check that the connection is working, plug both boxes into the wall. If the lights come on, the connection is intact.
If you wish to hide those two boxes from sight, you can. Just make sure the infrared area is easy to see. The transmitter sends information to the receiver using the infrared.
For the second step, plug the HDMI into the back of the wireless cable TV receiver then bring it close to your television. Connect the open end of the HDMI cord to the back of the TV. If you have multiple connections for HDMI cords on the back of your HDTV, use the one that says Output.
Lastly, plug the power cord for the wireless cable receiver box into the wall and power it on.

Setting Up the Wireless Cable TV Box

The first step to setting up your wireless cable TV box is to turn on your HDTV and navigate to the Menu. Next, find the System option. Here you'll find lots of options, select the option that says Video Input. If you don't see that option on your TV, select Video then Video Input.
Scroll to HDMI and select the one that's highlighted. The receiver's connection is here. Now your television should be on the HDMI channel. Exit the menu.
Use the Source button on the transmitter to select the HDMI option. You may have to press it a few times before reaching this option. Next, press the Channel button until you get to Channel 1. Repeat this last step on the receiver box as well. That's it.
At this stage you can use your cable TV remote to switch between channels and options as you normally would.
