How to connect a DVD player to your TV

At times, the TV is equipped with a single antenna input - nothing more. As for the portable models, old Soviet edition. Why did the TV to connect DVD-player? Savings: avoid paying the new equipment. Plasma panels are not cheap. Is it worth it to spoil the eyes CRT, decide for yourself. Discuss how to connect a DVD player to the TV. Along the way, will reveal the cause of unsuccessful catching images directly. Technology moves forward - follow on the heels.

Why can not I connect the TV antenna input and RCA

Physics introduced the concept of bandwidth. Analyzing the signal confronted with the term. Cable, air, earth's atmosphere, cascades of electronic devices. It turns out that the low frequencies of the image, the sound briefly extend ether - fade quickly. Engineers quickly came up with a technique fixes the difficulties. Found frequencies extending successfully invisible ether medium. First of all, the cable. The frequency is found as to lay useful information? Modulators are used. One parameter is the carrier frequency is changed, following the law information.

Carrier called harmonic (sinusoidal) oscillation, whose frequency is much higher than the spectrum of transmitted information. Musicians consider higher notes 20 kHz suffer information, overcoming ether cable frequency of at least 150 kHz (mid range DV).

If the low-frequency signal to change settings carrier spectrum becomes symmetric with respect to the carrier harmonics. I remember saying, engineers installed, the wave can easily pass cables, air. Tracked ester bandwidth (more precisely atmosphere), some waves are better than others. It is impossible to modulate the process of adjusting the parameters of the needs of the task at hand. Technological development of mankind is too low.

Change the parameters of cables. Products that transmit broadcasting, are designed to meet the needs of users. You can create a conductive line convenient way to convert radiation from the antenna signal again, but the technique makes life difficult. Represented slightly simplistic explanation, HF, CB are broadcast using capacity of waves to bend around the Earth. The greater effect demonstrate ET.

Converter satellite antennas uses conversion circuit described above. High frequencies are reduced, the transmission cable, decrypted TV console. Main readers understand: not a good life information transmitted by air, cable, extends the carrier frequency.

The receiving side performs the inverse process of removing information from a carrier. Received by an antenna, cable input signal is amplified. The task performs RF front end. Cable length and a half meters (a typical DVD player), strong damping will not have losses determines the length of the medium. The need to introduce the carrier is lost, DVD-player TV transmits information in the form of the playback speakers, screen. The technical solution will isolate from the design of devices modulator path demodulator.

The so-called «Tulip» (RCA), which occupies a dominant position in video:

1. Yellow channel transmits the image signal without the carrier.
2. White channel transmits mono sound signal of the left column.
3. Red channel transmits sound right speaker stereo mode.

Analog signal occurs, do not attempt to connect the DVD-player to the computer monitor. The display is a purely digital device. Accordingly, the structure of the signal did not resemble RCA. Industries released mount adapters, adapters perform transformation. Now readers will understand the characteristics of the direct connection to a DVD to the TV. Antenna high input will try to find the missing carrier. Bandwidth channels 1 - 12, will not see the DVD-player's signal.

Adapters to connect the DVD player to the TV

How to connect a DVD player to the TV? Find a store examining RCA adapter to the antenna connector (issue price of 640 rubles). 3D on the TV if you look unlikely. The converter is housed a small box, needs nourishment. AC adapter 230 volt 50 Hz is applied. By connecting a DVD-player on one side, TV - on the other, watch movies from discs. Not a bad option, some will not work for two reasons:

1. You need to pay for extra equipment (adapter).
2. The store is far away, watching a movie I want to right now.

Distressed enthusiasts other enthusiasts offer:

• Houses lying not get consoles 90s. Remember Sega, Dendy, other boxes, where to insert the game cartridge.
• Each console contains HF (RF) unit which converts a signal for supplying the antenna input of the TV.
• The block is provided with at least two output connectors composition "tulip» (3RCA).
• Fans noticed if on 3RCA to signal input (yellow, white Channel), antenna outputs output image fit.

How switching performed inside remains a mystery. It does not matter why the fluctuations scheme run from one outlet to another. Extract the HF (RF) unit of the attachment, the shorting plug contacts off buttons as necessary (when available such). Then inspect. Sometimes, not all the outputs are connected to the circuit. Put the jumper. Separate outputs are shunted by resistors can be short-circuited by removing the resistance at all.

It remains to energize the circuit. Traditionally used 8 - 12 volts (Chinese measure tester). Phone Adapter is not suitable, from the set-top boxes, portable radio, - please! If there is a chip stabilizer 7805, see if the food is taken from it. In this case, connect the phone adapter to output 7805. No difference will not be. Stabilizer 7805 simply convert 12 to 5 volts. A similar unit comprises a high frequency videorecorder. Find the entrance information, try to adapt the device to your needs.

Connecting a DVD player to the TV via SCART

Gifted recommended to deal with the SCART connector layout. Universal bus, where there is almost everything. Digging a collapsible plug SCART, the corresponding connector on the TV, forget problems. Seasoned hams parse layout, solder is used. Led lower SCART connector drawing, shall also be submitted: a yellow RCA connector is called composite video. See which terminals transmit sound, image:

• Picture:

1. Login: the yellow plug "tulip".
2. Yield: terminal 18 SCART - earth incoming video stream, terminal 20 SCART - an incoming video stream.

• Sound:

1. The left column. Login: white plug "tulip". Yield: terminal 6 SCART - input signal of the left column.
2. The right column. Login: red plug "tulip". Yield: terminal 2 SCART - input right column.

Land of sound common to both channels, is on terminal 4 SCART. Figure indicates the color component connector. Pins marked in red, green and blue. Later, consider the case. Know the difference between the "tulip" and SCART only in layout. You can connect the contact wires without any adapter. Finally, many people are interested in, perhaps, the question of where to take the land in the RCA? We believe that the outer sheath (shield). In any case, measure the tester. If you are calling from the circuit ground of the DVD player, it is very true. However, other options just not there.

If someone is not yet understood, the cable to connect the DVD to your TV need to solder by hand. To do this, you need to find a demountable connector SCART, RCA plug 3 under the "tulip". Many DVD players, especially indigenous Chinese, there is a component video output. It is different from the composite high quality. Plug in this case 5, three of which carry the video. Transmitted color difference signals between levels. High quality is obtained due to the redundancy.

The above-mentioned RGB in some cases suitable for component video. There was information that it does not work with all DVD-player, TV, check it is not necessary, for the simple reason that all the options are not pereberesh, as agreed earlier that the store away, or spend money not I want to. So, starting to solder.

• Picture:

1. Login: red plug YPbPr connectors.
2. Output: a SCART terminal 15 - the difference between red and luminance Pr, terminal 13 - ground Pr.
3. Login: blue connector YPbPr connectors.
4. Yield: terminal 7 SCART - difference between blue and luminance Pb, terminal 5 - earth Pb.
5. Login: green connector YPbPr connectors.
6. Yield: terminal 11 SCART - brightness Y, terminal 5 - earth Y.

• Sound:

1. The left column. Login: white plug connector YPbPr sound. Yield: terminal 6 SCART - input signal of the left column.
2. The right column. Login: red plug connector YPbPr sound. Yield: terminal 2 SCART - input right column.

Land of sound common to both channels, is on terminal 4 SCART. The question arises, how to correctly numbered. The answer is simple. SCART comprises a mechanical key - from improper turn protection. According to him and be guided. Considered connectors to connect the DVD to TV.
