What is a wireless video transceiver? How to share a cable box signal to many sets of TV?

wireless video transceiver transmitter and receiver

What is a wireless video transceiver?
In fact, it is the wireless transmitter and receiver, you can share the av signal from living room to another room. It named wireless av sender, or wireless tv transmitter and receiver, and so on.

How does multiple televisions share a set-top box? How to make many sets TV getting AV Signal from one sets TV box?
The principle of Set-top box is convert digital TV signal into analog TV signals, set-top box set up a smart card at the front, If purchase another set-top box would take charge again, one pcs set-top box only connect with one pcs TV, but now many home users are There are two or three sets TV, so that the extra TV become a decoration.
That’s why wireless video transmitter and receiver come out, such as  the user has one set set-top box at and three televisions. one of televisions is placed next to the set-top box, then you will need one av transmitter and two receivers. the set-top box has one group AV interface connected to the TV, then can not connected with transmitter, then av split is needed, convert one group av signal into two group av signal, then you can pick up the transmitter.

Useful guides on CNBgear electronic tech site:

The installation process only need to launch the connection set-top box, the receiver connected to the TV, power on, connect the AV cable between receiver and TV, then it will be work, the process not need to install any software program. And its simple, convenient ~ save the trouble of wiring!

What’s the difference between 2.4ghz and 5.8ghz? | PAKITE

Article from: What’s the difference between 2.4ghz and 5.8ghz?



The same frequency band Wireless TV to TV Sender and Wifi router may cause interference
At present, many new types of Wifi router with dual frequency as popular selling feature, some of Wifi route support double frequency band, so what’s is dual frequency band ?

The same frequency band Wireless TV to TV Sender and Wifi router may cause interference
2.4GHz and 5.8GHz are two frequency bands, does not affect the transmission speed.
Some of clients may think wireless 5.8ghz is much faster than 2.4ghz? Just like mobile 4g is fast than 3g and 2g, but actually, 5.8ghz is a frequency band, the same with 2.4ghz, there is no difference between 2.4ghz and 5.8ghz, it’s like two road, there would influence each other, but for 3G and 4G in mobile phone, it’s means generation 3 or 4 communication technology , so the upload and download is difference.

Then why put forward 5.8ghz?
It’s because there is many 2.4ghz wireless device, also 2.4ghz frequency can contain 11 band, but with time goes by, all kinds of IT device become common, like most of iPad, 2.4ghz Wireless TV to TV Sender, mobile, PC, Game player, Bluetooth, wireless mouse use 2.4ghz frequency, then it will cause interference.

Advantage and Shortcoming of 5.8ghz
The advantage is 5.8ghz has anti-interference than 2.4ghz since most of wireless device in the market is 2.4ghz. But the penetrate ability is weak than 2.4ghz, The higher frequency the worse penetrability.



2.4GHz and 5.8GHz is simply the two band for Wifi router, 5.8GHz is mainly to solve the problem of 2.4GHz too congested, both in the transmission speed and no difference.

Smart wireless tv sender installation | PAKITE

Transmitter connect cable box - Wireless AV Sender
Wireless tv sender(also known as video sender, Digisender, or wireless av sender), is a wireless transmission device to share cable tv signal wirelessly in different room and different floor. It's installation is very easy, no matter for RCA/AV port tv sender, or for HDMI tv sender, but it still some details need to be attention.

Like smart tv sender support two group av input and 38/56KHz frequency band IR Remote control. But we have to make sure transmitter and receiver should be in the same channels, or it will be can’t work.

Transmitter and Receiver should be keep on same channel(RCA or HDMI).
a. 433MHz Wireless access C1-C8 should be same, normal control at receiver will be ok.
Receiver connect television or viewing device - Wireless AV Senderb. Keep IR Remote control frequency band F1/F2 should be same, normal F1 is 38KHz frequency band and F2 is 56KHz frequency band.
c. Since smart tv sender support two group av input, so transmitter signal input is AV1, then receiver signal output should be AV1.
d. Keep av transmitter and receiver was in the same channels, like transmitter was 01 channels, then receiver should be 01 channels. If for other Dial switch also should be same.
e. Keep both transmitter and receiver was in the same channels, then you can adjust the above function at receiver ends.

Why my a/v transmitter receiver can not work well?

 Sources: Why my a/v transmitter receiver can not work well?


Wireless product is a magical product. You test it, it can not work, but I test it, it working prefect. But why?

If the av sender can not work as normal, we should contact with seller ask for solution nor return the goods and complain the quality is not good, that’s make both seller and buyer fells unhappy. PAKITE would like to eliminate your negative emotion and come out solution for you. 

Here we talked about the RCA and HDMI av sender transmit audio but no video or transmit video but no audio. If you meet that questions.

First: please double check all cable connection is correct, if your av sender is connect with signal or monitor by RCA Cable, then you have to plug the red yellow white cable with corresponding color jack. please noted: red , blue, green is not RCA Jack, it’s different signal source.

Second: please double check both transmitter and receiver cable connection is no loosen, if still not work, you can try to change another av cable.

Third: this condition is rare, but still exist. Some of satellite receiver has HDMI Jack and RCA/ S-video Jack, so user will connect one set tv with satellite receiver by HDMI Jack, at same times connect transmitter with satellite receiver, which means the satellite receiver has two group av output, but some of satellite receiver do not support two group av signal out put at the same times, that will lead to another tv at receiver end no audio or video signal, even if make the receiver can not work. If you meet the third situation, you just need one transmitter with two receiver, it will be workable.

Any other questions about wireless av sender, welcome leave message with us.

Wireless Video Transmitters

wireless video senderA video sender (also known as wireless video senderAV sender or audio-video sender) is a device for transmitting domestic audio and video signals wirelessly from one location to another. It is most commonly used for sending the output of a source device, such as a set top box, DVD player, CCTV camera, DVR, blu-ray player, satellite television decoder, to a television or viewing device in another part of a property and provides an alternative to cable installations. There are two types of interface: RCA or AV and HDMI. HDMI av sender is for transmitting HDMI signal wireless, and there are two types output resolution of a HDMI wireless a/v sender: 576p and 1080p. 576p HDMI av sender is the new wireless av product which launched by PAKITE at 2016. Following is something about wireless video transmitters.

2.4GHz Video Transmitters

2.4GHz Wireless Video Transmitters are an inexpensive solution for sending security camera video wirelessly. There are two types of 2.4GHz video transmitters. The first are analog video transmitters that use RF signals to transmits video and require line of sight with no obstructions between the transmitter and receiver. The 2.4GHz analog video transmitters are great for solutions where Real Time video is required without any lag, or where the signal must be received at multiple receivers. The second type are digital wireless 2.4GHz transmitters that utilize a WiFi like signal modality which allows penetration through obstructions based on their density and strength of the transmitted signal. It is possible to penetrate a solid concrete wall or thin sheet metal wall using a 2.4GHz digital wireless transmitter and a 2.4GHz 16dbi high gain panel antenna.

5.8GHz Video Transmitters

5.8GHz Wireless Video Transmitters allow for long range video transmission without interference from WiFi. At CCTV Camera World we specialize in wireless video transmission, and sell only FCC certified video equipment that conforms to all Federal regulations. The analog 5.8GHz video transmitter can be used along with its 5.8GHz wireless receiver to send video signals. This 5.8GHz wireless video transmitter is great for converting a wired security camera in to wireless because it transmits a Real Time video signal without any frame drops or choppiness. Video quality is almost as good as wired, as long as signal transmission occurs in line of sight and the proper types of antennas are used to maintain good signal strength.

What is HDMI AV Transmitters and Receivers? | PAKITE

PAT 580 HDMI Wireless AV SenderRight now, HDMI Connection become the mainstream interface, so Wireless HDMI Transmitter and Receiver comes with HDMI interface. So, What is HDMI wireless av transmitter?

Wireless av transmitter is for transmit AV Signal from signal sourcelike DVD/DVR/TV Boxto Monitor( TV/display screen), it’s like a wireless bridge between signal source with monitor. HDMI wireless av sender has the same function with wireless av sender, like the upgrade vision of wireless av sender.

It is connection upgrade : for the connection jack, common wireless av transmitter is RCA/AV Jack, but it’s becomes out date in the recent years, HDMI connection becomes common in the new TV/DVD/DVR/TV Box, all of av products support HDMI Input/Output. So RCA wireless av transmitter needed upgrade, we design the new model PAT-580 support HDMI Input/Output.

It is resolution upgrade : for RCA wireless av sender, receiver output resolution is 480P, when the HDMI connection come out, resolution also upgrade. like 480P, 720P, 1080P, 4K. It’s  technical innovation for AV Field.


HDMI Wireless av sender is for cater to market demand, it’s resolution upgrade from 480P to 576P, it’s more slowly than TV resolution, but there is a lot of space for improvement.

Wireless Cable TV Audio/Video Transmission Systems

Wireless Audio/Video Cable TV Transmitter and Receiver

Wireless audio/video transmission systems consist of two main parts: a Transmitter and a Receiver. The Transmitter uses a wired connection (most commonly via Composite RCA cables or HDMI cables) with the AV output from a source component such as a cable box, satellite receiver, DVD player, Blu-ray Player, Roku, DVR, or Apple TV. The Receiver uses a wired connection with the AV input(s) on a TV. 
 
Once the Transmitter and Receiver are installed the AV signals are sent from a source component out to the Transmitter, wirelessly on to the Receiver and out to the TV. Typical applications for this setup are when the Receiver may be located inside a cabinet, in an entertainment rack, behind closed doors or in another room; and/or the TV is located where a wired connection is not possible or may just simply be an eyesore, like a flat panel wall mount application. Without the need to make long AV wire connections you can place your devices almost anywhere.
 
Useful posts from CNBgear tech site:

CHANGING CHANNELS REMOTELY
A common question with a wireless setup like this is how to change channels if the source component is in another room or in a location without a line of sight to the IR remote. Fortunately most systems include a built-in IR pass-through system. The Receiver features an infrared (IR) receiver, that takes in a signal from your IR remote and passes it wirelessly to the Transmitter and out to an emitter that repeats the IR signal to the source component. If the wireless solution doesn't include an IR pass-through, or if a little more discrete installation is needed.

WIRELESS FREQUENCY
It is also important to understand the frequency that the wireless system uses. Almost every home today is operating on at least one, if not multiple, wireless systems - wireless home automation, phones, doorbells, intercoms, security systems, sensors, speakers and more. Many of these use lower end frequencies, which you will commonly see as a specification of 314 MHz, 433 MHz or 900 MHz. More recently higher end bandwidths have been used, which you will see as a specification of 2.4 GHz or 5.8 GHz. The frequency of the device doesn't necessarily correlate to the quality of the product. The important thing to understand is that you want to try and make sure there aren't multiple products using the same frequency, as this can cause interference and decrease the reliability of the products. Ideally, you will want to be using different frequencies for each set of products to ensure the optimal results of your installation.

EXPANDABILITY
The final consideration on picking the right wireless video transmitter is it's expandability, or the ability to send a wireless signal to more than one receiver. Not all system allow for this, So if you have more than one remote TV that wants to tap into the wireless video signal, just purchase an additional receiver for a system that supports it.

New Opportunity on PAT-580 HDMI Wireless | PAKITE

The unit price of Full HD wireless av sender(what is it?) expensive, but the transmission range is very short. so now PAKITE develop a new model wireless HDMI transmitter and receiver with long transmission range but cheaper.
PAT-580 is newest wireless HDMI video transmitter developed by PAKITE. Most of typical model like PAT-220/PAT-530 is RCA jack, but right now, most of tv cable box has HDMI Jack only, so we have to follow the times. It’s a new model with interface - HDMI, that support HDMI 1.4/2.0.
HDMI Transmitter and Receiver
Look at the transmitter, there is two HDMI interface, one HDMI input and another HDMI output. HDMI input is for connect with signal source, like DVD/TV Cable Box/NVR, the HDMI output is for connect with TV directly, which means one sets PAT-580 could connect two set TV. About the receiver, there is only one HDMI output interface connect with TV, it keeps the long distance transmission function, so you can place the PAT-580 at different rooms.
The transmission range 300 meters is for open space, if there is obstacle between transmitter and receiver, then the transmission distance will be weaken, after passed one wall, the transmission range around 10-15 meters. Also the transmission distance is depend on the wall thickness.

How to select a worthy TV to TV Sender

 
 
TV to TV Sender, also known as wireless av sender, audio/video transceiver, av signal extender, or wireless video transmitter and receiver. It's for transmit audio and video signal wirelessly from signal source like cable box or blue-ray player to viewing device like television or IPTV. By using a TV to TV Sender, you can place your RCA or HDMI port device anywhere(like kitchen, bedroom, garden, dinning room) in your house as you like, and no need to running much wires. RCA wireless connection by using an universal TV to TV Sender, and HDMI to HDMI wireless connection by using a HDMI av sender. There are different types of TV to TV Sender, like different transmission range, different anti-interference ability, different force of penetration. So you should do some research to select a worthy AV Sender.

How a TV Sender Works

Wireless TV to TV Sender Transmitter and ReceiverTo make an informed decision when it comes to buying a TV to TV Sender, the buyer must first understand how a TV Sender works. A TV sender is connected to the main television by way of a SCART socket. The SCART socket is the largest socket located on the back of the television.
The receiver is plugged into the secondary television by way of its SCART connection. Once connected, the secondary TV is able to receives radio signals transmitted from the TV to TV sender connected to the main television in the other room.
With a TV sender, the user can view the television signal on two different televisions in two different rooms. The receiver can also send a wireless signal to the TV sender, commanding it to perform specific functions, such as changing the volume. This is only possible through the use of an infrared sensor on the receiver. The remote control for the main television can be used with the receiver from the secondary television. The remote control is pointed at the infrared sensor on the receiver. When the user pushes the volume button, a signal is transmitted from the secondary TV to the TV sender on the main television. It is important to source an additional remote control as this avoids the user having to take the remote control with them when they move to another room to watch television.

Types of TV Senders

There are two basic types of TV senders: low-definition and high-definition TV senders. Each transmits in a specific frequency range: 2.4 GHz or 5.8 GHz. The different frequencies are transmitted by radio waves through the use of an antenna attached to the sender and receiver. The frequency range determines the overall quality of the transmission signal of the sender to the receiver.

Low-Definition, 2.4GHz

A low-definition, 2.4 GHz TV sender is more affordable than a high-definition, 5.8 GHz TV sender. It is more affordable, because it is used to link standard televisions. The low-definition, 2.4 GHz TV sender’s television picture may be fuzzy or difficult to view due to frequency interference caused by other devices in the home. Such sources could include baby monitors, WiFi, and anything that operates with a 2.4 GHz frequency.

High-Definition, 5.8 GHz

A high-definition, 5.8 GHz TV sender is more expensive than a low-definition, 2.4 GHz TV sender. The high-definition, 5.8 GHz TV sender employs a relatively new form of technology that is still evolving. It is more expensive because the signal output and picture are clearer, and the range of transmission extends further than a low-definition, 2.4 GHz TV sender's transmission range. This newer technology allows several high-definition devices like Blu-ray players to connect to the TV sender rather than just one device. An HDMI splitter is required to connect the television and the high-definition sources with each other. With this setup, there is little interference from other radio frequencies as is the case with the low-definition, 2.4 GHz TV sender.
When there is interference such as with 5.8 GHz cordless telephones, the user can change the specific channel within the frequency band to a channel other than the one used by the cordless telephones. Both the TV sender and receiver broadcast frequency channels should be the same. With the high-definition, 5.8 GHz TV sender, the transmission signal can extend up to nine metres, depending on the thickness of walls. This extended range of transmission is made possible through a remote control extender.

Remote Control Extender

A special feature of a high-definition, 5.8 GHz TV sender is a remote control extender. The remote control extender requires a base unit and an extender unit to operate. The base unit is positioned in the room with the primary television. The extender unit is positioned in the room with the secondary television. When the remote control transmits signals to the extender unit, they are carried wirelessly to the base unit.
If the transmitter on the extender unit does not make line of sight contact with the remote control sensor, the base unit located in the other room may not receive the command transmission. Batteries are also not strong enough for effective transmission between base unit and extender unit. Both units need to be plugged into a wall outlet or other compatible power supply.
The following table illustrates some key differences between the two basic types of TV senders. The differences are in the areas of transmission range, signal quality, and cost.

AV Sender

Transmission range

Signal Quality

Cost

Low-definition, 2.4 GHz
Low
Depending on surrounding wireless devices
Inexpensive
High-definition, 5.8 GHz
High, extending to 9 m with remote control extender
Suffers little interference from surrounding wireless devices
Expensive
The table above highlights the key features of low-definition, 2.4 GHz and high-definition, 5.8 GHz TV senders. These are generalisations only. The buyer needs to keep in mind that the signal's transmission may be affected by other radio transmitting devices like cordless phones, baby monitors, and the home WiFi network. Less frequency interference means better picture quality.

Limitations of TV Senders

Along with these positive aspects, there are some drawbacks to using the device. The buyer should be aware of these issues so that they can make an informed purchasing decision.

Multiple Senders

When a buyer purchases more than one TV sender, it is important to remember that the TV senders may transmit signals on the same frequency band. This can cause signal interference between the TV senders, resulting in poor picture quality. The buyer should select different frequency bands for each TV sender.

Channel Transmission

The transmission of television signals through walls is an important aspect of the overall operation of a TV sender. The signal, though, cannot transmit multiple television channels at a time. Only a single television channel can be transmitted and watched on both televisions at one time.
