HDMI receiver | PAKITE

An HDMI Receiver is a newer technology. There are lots of different types of HDMI receivers available that can be purchased today. They are starting to become a standard for the technology produced, and depending on what type of equipment you have, you may need an HDMI receiver. And HDMI receiver will work together with HDMI sender (transmitter).

HDMI is short for high-definition multimedia interface. In the past, HDMI was known as a cable that you purchased that hooked up to your TV or PC. This cable transferred multimedia data from your TV or PC to a receiver. The receiver sorted out the data and puts a picture on your TV. Created in 2003, this technology has come a long way in the past few years.

The HDMI receiver can be bulky. It basically passes one technology through to the next. So, if you have something that doesn’t support the HDMI cables you have to have a receiver that can unscramble the data and put it on your TV or your computer. The receiver can route the HDMI data from 3 different sources and put it all in one. This will take away the need to have an HDMI switcher.

There are many different types of the HDMI receiver. Some of these types have two or three different HDMI ports that you can plug into. So, if you have lots of different pieces of technology all hooked up, you don’t need a ton of cords. All you have to do is plug it into the receiver and switch between the different options with the remote. It makes it easy. No unplugging to use another piece of equipment!

HDMI specializes in helping with analog-to-digital video conversion. By having a receiver, you have only one cable running to convert your picture from analog-to-digital. This has helped increase technology, and does away with some older models of TV’s and computer screens to make room for newer technologies.

The HDMI receiver has really simplified the process of hooking your various technologies and running them through your TV or computer. Before, you had to have a connector, a certain port, a plug that helped convert one thing to another. Once HDMI was developed, it did away with all that. With the capability run eight different data sources through one plug, it is so much easier.

If you’re looking to make your TV set up easier, it’s time to invest in an HDMI receiver. You’ll be so pleased with the lack of cables and cords running everywhere that you’ll wonder why you didn’t do this sooner. Take a look at how HDMI receivers can help you, and stop overwhelming yourself. Technology is made to be simple.

Upgrading to HDMI cables and HDMI receivers is great. If you haven’t invested yet, now is the time. Go get an HDMI box and watch the difference that it will make. You’ll be so happy; you’ll never go back to your previous technology.

AV Receiver

An audio/video receiver (AVR) (also known as av receiver, wireless av receiver, Digireceiver, wireless tv receiver, video receiver) is a consumer electronics unit used in a home theater. Its primary purpose is to receive audio and video signals from a number of sources and process them to drive loudspeakers and a display. Possible displays include, television, monitor, or video projector while the inputs may come from, television, satellite receiver, radio, DVD players, Blu-ray Disc players, VCRs, and video game consoles. The AVR source signal and other settings, including volume, are normally set by a remote controller.And the wireless av receiver always works with the wireless av transmitter, multi receivers can receive signal from one transmitter.

Usage

The term receiver basically refers to an amplifier that has a built-in radio tuner. With AV receiver the basic functionality is to receive an audio signal, amplify the audio signal, and allow pass-through of the corresponding video signal to a display device such as a projector or a television.

As home entertainment options expanded, so did the role of the receiver. The ability to handle a variety of digital audio signals was added. More amplifiers were added for surround-sound playback. Video switching was added to simplify changing from one device to another. Within the last few years, video processing has been added to many receivers.

The term audio/video receiver (AVR) or Home Theater Receiver is used to distinguish the multi-channel audio video receiver (home theater receiver) from the simpler stereo receiver, though the primary function of both is amplification.

AV receiver may also be known as digital audio video receiver or digital media renderers.

The AV receiver is classified as an audio frequency electronic amplifier. But with the rapid addition of several features, AV receivers now generally have significant additional functionality.

Features

Channels

Stereo receivers have two channels of amplification, while AV receivers may have more than two. The standard for AV receivers is five channels of amplification. These are usually referred to as 5.1 receivers. This provides for a left, right, center, left surround and right surround speaker to be powered by the receiver. 7.1 receivers are becoming more common and provide for two additional surround channels, left rear surround and right rear surround. The ".1" refers to the LFE (low-frequency effects/bass) channel, the signal of which is usually sent to an amplified subwoofer unit. 5.1 and 7.1 receivers don't usually provide amplification for this channel. Instead, they provide a line level output.

Amplifier power

Audio amplifier power, normally specified in Watts, is not always as significant as it may seem from the specification. Due to the logarithmic nature of human hearing, audio power or sound pressure level (SPL), must be increased by ten times to sound twice as loud. This is why SPL is measured on a logarithmic scale in decibels (dBs). An increase of 10dBs results in a perceived doubling of loudness. Another complication with human hearing is that as the SPL decreases the perceived volume of the low and high frequencies decreases faster than the central frequencies around 2 kHz.

There are different standards for rating amplifier power depending on country, manufacturer, and model. Other factors also come into play: distortion, headroom, speaker efficiency. Thus, it is possible for an amplifier with a specified lower power to sound louder than an amplifier with a specified higher power.

Because of theses factors it is not easy to compare the perceived loudness of amplifiers solely from their specified power in Watts.

Decoders

AV receivers usually provide one or more decoders for sources with more than two channels of audio information. This is most common with movie soundtracks, which use one of a variety of different types of encoding formats.

The first common soundtrack format was Dolby Pro Logic, a surround sound processing technology. This format contains a center channel and a surround channel mixed into the left and right channels using a process called matrixing, providing a total of four channels. Receivers with Dolby Pro Logic decoders can separate out the center and surround channels from the left and right channels.

With the introduction of the DVD, the Dolby Digital format became a standard. Dolby Digital ready receivers included inputs and amplifiers for the additional channels. Most current AV receivers provide a Dolby Digital decoder and at least one digital S/PDIF input which can be connected to a source which provides a Dolby Digital output.

A somewhat less common surround sound decoder called DTS is standard on current AV receivers.

When Dolby Labs and DTS introduced technologies to add a rear center surround channel, these technologies found their way into AV Receivers. Receivers with six amplifiers (known as 6.1 receivers) will typically have both Dolby and DTS's technologies. These are Dolby Digital EX and DTS ES.

Dolby introduced Dolby Pro Logic II to allow stereo sources to play back as if they were encoded in surround sound. DTS introduced a similar technology, NEO:6. These decoders have become common on most current receivers.

As the number of playback channels were increased on receivers, other decoders have been added to some receivers. For example, Dolby Labs created Dolby Pro Logic IIx to take advantage of receivers with more than five channels of playback.

With the introduction of high definition players (e.g. Blu-ray Disc and HD DVD), yet more decoders have been added to some receivers. Dolby TrueHD and DTS-HD Master Audio decoders are available on many receivers.

DSP effects

Most receivers offer specialized Digital Signal Processors (DSP) made for handling various presets and audio effects. Some may offer simple equalizers and balance adjustments to complex DSP audio field simulations such as "Hall", "Arena", "Opera", etc. that simulate or attempt to replicate as if the audio were being played in the places through use of surround sound and echo effects.

AV inputs/outputs

There are a variety of possible connections on an AV receiver. Standard connectors include:

Analog audio (RCA connector, or occasionally XLR connector)

Digital audio (S/PDIF; TOSLINK or RCA terminated coaxial cable)

Composite video (RCA connector)

S-Video

SCART video (primarily used in Europe and very uncommon in many other parts of the world)

Component video

HDMI

USB (usually involves special computer circuitry to read video formats from a file system)

Analog audio connections usually use RCA plugs in stereo pairs. Inputs and outputs are both common. Outputs are provided mainly for cassette tape decks.

Analog audio connections using XLR(Balanced) connectors are uncommon, and usually found on more expensive receivers.

Digital connections allow for the transmission of PCM, Dolby Digital or DTS audio. Common devices include CD players, DVD players, or satellite receivers.

Composite video connections use a single RCA plug on each end. Composite video is standard on all AV receivers allowing for the switching of video devices such as VHS players, cable boxes, and game consoles. DVD players may be connected via composite video connectors although a higher bandwidth connection is recommended.

S-Video connections offer better quality than composite video. It uses a DIN jack.

SCART connections generally offer the best quality video at standard-definition, due to the use of pure RGB signalling (although composite and S-Video may alternatively be offered over a SCART connector). SCART provides video and audio in one connection.

Component video has become the best connection for analog video as higher definitions such as 720p have become common. The YPbPr signalling provides a good compromise between resolution and colour definition.

HDMI is becoming common on AV receivers. It provides for the transmission of both audio and video. HDMI is relatively new technology and there are reported issues with devices not properly working with each other (referred to as hand-shake issues between devices), especially cable/satellite boxes connected to a display through an AV receiver. Different levels of support are provided by receivers with HDMI connections. Some will only switch video and not provide for audio processing. Some will not handle multi-channel LPCM. Multi-channel LPCM is a common way for Blu-ray Disc and HD DVD players to transmit the best possible audio.

Video conversion and upscaling

Some AV Receivers can convert from one video format to another. This is commonly called upconversion or transcoding. A smaller number of receivers provide for de-interlacing of video signals. For example, a receiver with upconversion, deinterlacing and upscaling can take an interlaced composite signal at 480i (480 lines per frame sent as a field of 240 even numbered lines 0,2,4,8...478 followed by a field of 240 odd numbered lines 1,3,5,...479) and convert it to component video while also deinterlacing and upscaling it to a higher resolution such as 720p (720 lines per frame with all lines in normal sequence 0,1,2...719).

Radio on AVRs

AV receivers though primarily used for amplification may or may not have an inbuilt AM/FM radio tuner among other features such as LAN connectivity for various Internet applications and some with multi-room audio solutions.

Even though some AVRs may have an AM/FM tuner it is not a primary or mandatory function as an AVR still remains an amplifier.

Some models have HD Radio tuners.

Some models have Internet radio and PC streaming access capabilities with an Ethernet port.

How to Transfer a Wireless TV Signal ?

A television signal can be transferred from one TV to another video display, providing that both have video inputs and outputs. A wireless Audio/video transmission system(wireless av sender) can transfer the signal and is available from an electronics store or the TV accessories section of a department store. Audio/video cables found in most households, but which can be acquired from the same stores as the wireless Audio/ Video transmission system, must be used as well.

Place the wireless tv transmitter next to the television(By the way, if your Television has HDMI port, you should use HDMI wireless transmitter with hdmi jack). Plug its power cord into an outlet. Insert one end of a video cable into the video output on the back panel of the TV (labeled "Composite" on some sets). Insert the other end of the video cable into the video input on the av transmitter. Repeat this procedure with an audio cable, only plugging the red and white plugs at one end into the red and white outputs on the TV and the red and white inputs on the av transmitter.

Place the wireless tv receiver next to a video display on which you want to watch the TV signal being transmitted wirelessly, for example, another TV. Plug the av receiver's power cord into an outlet. Insert one end of a video cable into the video input on the back panel of the video display device. Insert the other end of the video cable into the video output on the receiver. Repeat this procedure with an audio cable, only plugging the red and white plugs at one end into the red and white outputs on the av receiver and the red and white plugs on the other end into the red and white inputs on the video display device.

Turn on the TV to which the wireless tv transmitter is connected. Turn on the video display device to which the wireless tv receiver is connected. Press "Menu" on the remote that controls the video display device.

Navigate through the settings until you come to the "Video input" or similarly named menu. Select this menu. Highlight the video input to which the video cable is connected. Press the "Enter" or "OK" button, depending on the make of the remote. Press "Menu" to exit the settings so that you can watch the TV signal being transferred to the video display device.
