Ask questions about radio broadcasting

In the past, the radio director was responsible for the control and effect of the program's broadcast.

The current director is basically only responsible for the answering work of ****, and some directors will help the host hang some cushion music, festival goals, etc. Some are also responsible for connecting the line conditions and other information, recording information, and basically focusing on the best connection and transfer. Sunday rest is also a rotational holiday, however, there will be a director on duty every day.

Basic requirements for the director:

2. Interested in broadcasting, able to bear hardships and stand hard work, team spirit, responsible work, strong sense of responsibility, and Mandarin.

3. Solve emergencies that occur during radio broadcasting.

4. Record the work record of the radio station on duty (3 directors and 3 shifts, with night shifts).

5. Have a good attitude and self-cultivation, need to patiently answer the audience's questions, and do not have disputes with the audience.

6. High school education or above, good appearance, gender and age are not limited, and there is a certain ability to communicate and coordinate.

1.Love**, understand the current pop music;

2.Strong psychological quality, good teamwork ability;

3.Have good writing skills;

4.Good communication skills;

5.Familiar with the basic operation of the computer, familiar with QQ, MSN functions, fast typing speed;

6.Flexible mind and quick response;

Job Responsibilities: Communication with Internet Radio listeners and interactive information transmission between the host and the listeners.

The sound that can be heard by the human ear is called sound waves, and the frequency range of sound waves that can be heard by the human ear is 20Hz 20000Hz. Sound waves are highly attenuated as they travel through the air and travel over close distances.

The frequency of radio waves is much higher than the frequency range that is audible to the human ear, and the medium of propagation is the electromagnetic field. The distance of transmission is long.

In order to make the sound travel farther, people let the sound wave signal ride the "horse" of the radio wave signal. In technical terms, I call the "horse" carrying sound waves carriers.

The transmission of radio programs takes place at radio stations. The sound waves of the broadcast program are converted into audio frequency electrical signals through electroacoustic devices, and amplified by the audio frequency amplifier, and the oscillator generates a high-frequency equal amplitude oscillation signal; The modulator makes the high-frequency equal-amplitude oscillation signal modulated by the audio signal; The modulated high-frequency oscillation signal is amplified and sent to the transmitting antenna line to be converted into radio waves for radiation.

The reception of radio broadcasts is achieved by radio. The receiving antenna of the radio receives radio waves from the air; The tuning circuit selects the signal of the desired frequency; The detector restores the high-frequency signal into an audio signal (i.e., demodulation), and the audio signal obtained after demodulation is amplified to obtain sufficient driving power; Finally, the broadcast content is restored through electroacoustic conversion.

To sum up, the transmission and reception of radiocommunication (broadcasting also belongs to the category of radiocommunication) can be summarized as the conversion process of three opposite aspects, namely: transmission of information - low-frequency signal, low-frequency signal - high-frequency signal, high-frequency signal - electromagnetic wave.

Radio was born in the 20s of the 20th century and officially launched on November 2, 1920. China's first radio station was built in 1923 and was run by foreigners. Chinese People's Broadcasting was founded in December 1940, that is, the predecessor of the People's Radio, Yan'an Xinhua Radio.

The radio director is the assistant of the radio host, helping the radio host to answer the listener** and select** to access the live broadcast room; Help the radio host dial the guest** and connect ** to the live broadcast room; Help radio sails such as hosts to filter out ** that has nothing to do with the program, harassment**, and ** that violates national laws and regulations; Help the radio host draw the lucky listeners of the SMS platform; Help radio hosts keep track of listeners**; Remind the radio station to host the banquet to receive and hang auspicious times; Help the radio host to contact the technical department when there is a problem with the program; Help the radio host with other things outside of the studio. The radio director has a special broadcast room, which is generally adjacent to the live broadcast room, and can directly observe every move in the live broadcast room. Radio directors generally communicate and contact with the host through electronic microphones.

The radio director is a necessary assistant to the radio host.

Traditional radio director: Answering the plexus and pretending to talk.

Internet radio director: ** information on QQ or MSN.

Whether it is a traditional radio station or a regular network radio station, the director also has a common responsibility to supervise the host (overtime, lateness, broadcast accidents), and coordinate the work of the host - when the host is too late to arrive at the station, he must help contact other hosts in time to replace the class, and go to the Chong's live broadcast room to make up for **, so that the program can not be airborn.

It is not so easy for the traditional radio director to connect **, not to pick up Zheng San**. The director is responsible for reviewing and analyzing whether the other party** can access the live broadcast room and whether there is a problem with the other party's remarks. In addition, the director is responsible for the work of transmitting information, and there is any important information during the live broadcast, such as important news that the news station needs to broadcast temporarily, traffic information from the traffic police center and so on.
