Description

Broadcasting receiving terminal, and control method

The present invention relates to a broadcast receiving terminal, and more particularly, to a broadcast receiving terminal for accurately displaying a broadcast start and a control method thereof.

In general, various electronic devices are made through the development of electronic communication technology, and various devices such as mobile phones and smart phones are widely used.

Among them, smart phones are currently being widely used, and many users are using them to perform various tasks such as telephone, email, and wireless internet.

In general, a smartphone can be used as a broadcast terminal by installing a predetermined application.

The broadcast terminal receives a predetermined control signal from the broadcast control system, photographs a target to be broadcasted, and the screen or voice photographed by the broadcast terminal is transmitted to a terminal of broadcast receivers through a separate relay server. Then, the broadcast receivers can watch the screen taken by the broadcast terminal through the broadcast.

Such a broadcasting process is much simpler than conventional broadcasting, and the image quality is not as good as that of conventional high-quality broadcasting equipment, but is very useful for broadcasting in an emergency or an area where the broadcasting equipment cannot be carried.

In other words, if you have only one smartphone, you can broadcast freely anytime and anywhere.

A broadcast terminal and a broadcast control system are basically required for such a broadcast, and a relay server for relaying a broadcast to a terminal of a broadcast receiver is needed if necessary.

By the way, the broadcast transmission in the conventional mobile broadcast terminal can only broadcast by the intention of the sender. That is, the broadcast control system hardly suggests a method of transmitting a signal. In some cases, the operator does not support temporal synchronization, but transmits a general text or voice to the broadcast sender to start broadcasting, and it is difficult to accurately synchronize in time.

In this conventional method, when the broadcast control system operator notifies the broadcast to start, the broadcast sender transmits the broadcast content to the broadcast terminal. This method is difficult to determine exactly when to start the broadcast. There was an uncomfortable disadvantage.

On the other hand, the broadcast receiving terminal had only a function of displaying broadcast information transmitted from the broadcast transmitting terminal.

As described above, it is difficult to conventionally apply a broadcast terminal, which is difficult to synchronize broadcasts, to a general broadcast system, and the broadcast receiving terminal performs only a simple function.

In addition, the controller 410 may operate the camera unit 470 according to the selection of the input unit 460, and display image and audio information received from the camera unit 470 on the display unit 450.

A communication method between the broadcast terminal and the broadcast control system having such a configuration will be described below.

5 is a diagram illustrating a communication method between a broadcast terminal and a broadcast control system according to an embodiment of the present invention, and FIG. 6 is a flowchart illustrating a broadcast control method of a broadcast terminal according to an embodiment of the present invention.

Referring to FIG. 5 or FIG. 6, first, the broadcast terminal 200 transmits communication information to the broadcast control system 300 according to a user's selection. Here, the communication information may be test broadcast information or may be a synchronization signal sent in advance before broadcasting (S510).

Before broadcasting, the controller 210 operates the camera unit 270, and the camera unit 270 captures an image and an audio under the control of the controller 210. The controller 210 transmits the captured information to the broadcast receiving terminal 400 and the broadcast control system 300 through the communication unit 230.

As shown in FIG. 5, in the broadcast terminal and the broadcast control system, time stamps (ts) are recorded in the storage units 240 and 340 for respective video and audio signals. In addition, these images have a time delay due to the characteristics of the network 100 and buffering of the broadcast control system 300, and delayed screens are displayed on the display units 250 and 350.

As a result, the broadcast controller requests a broadcast preparation by viewing the delayed screen displayed on the display unit 340 of the broadcast control system 300. In addition, since the transmission signal of the broadcast controller is transmitted to the broadcast terminal only through the network, time delay occurs again.

Therefore, in view of such a point, when the broadcast control system 300 sends a signal to the broadcast terminal 200, the broadcast time point information d must satisfy the condition of Equation 1 below.

At this time, the minimum effective waiting time is the minimum time that the broadcast transmitter can prepare for broadcasting, and the delay time is the sum of the packet transmission / reception time of the broadcast signal and the buffering time of the broadcast control system. In addition, the delay time may further include other times, and the delay time may vary depending on the time zone according to traffic conditions.

With the communication connected in this way, the broadcast control system 300 inputs the broadcast time input according to the selection of the broadcast controller, that is, the time information that the broadcast starts from some time from now, for example, 10 seconds to broadcast after 10 seconds. When the time is input, the controller 310 determines whether the input time satisfies the condition of the above equation.

If the input time does not satisfy the condition of the above formula, a warning message to be input again is displayed on the display unit 340, and the input is received again.

On the other hand, if the input time satisfies the condition of the above formula, the controller 310 transmits the input time to the broadcast terminal 200 as the broadcast start information together with the current time ts n1 as the broadcast time information d. do. Referring to FIG. 4, the communication unit 330 transmits ts n1, which is the last time when a signal occurs together with the broadcast time information d.

For example, assume that broadcast time information is 10 seconds and the current time ts n1 is 9:59:50. That is, the broadcast start time should be 10 o'clock. Referring to FIG. 5, the current time is based on the time sent from the broadcast terminal 200, and the broadcast terminal 200 and the broadcast control system 300 are synchronized with each other. It is set as 200 hours. If necessary, the time may be adjusted based on the broadcast control system 300.

Then, the communication unit 230 of the broadcast terminal 200 receives the broadcast start information (S520).

Then, the control unit 210 compares the broadcast start information with the current time to calculate the broadcast waiting time, which is the remaining time until the broadcast start time (S530), and calculates the calculated broadcast waiting time at a predetermined time interval (1 second unit). The display unit 250 displays the display unit 250 (S540).

Here, the controller 210 calculates the broadcast standby time d1 to be expressed on the display unit 250 using the broadcast time information d, the time ts n2 at the time of receiving the signal, and the transmission time ts n1. Calculate as shown in Equation 2.

Thereafter, the display unit 250 displays the calculated broadcast waiting time d1 on the screen at a predetermined time interval (1 second).

On the other hand, while the broadcast control system 300 transmits the desired broadcast viewpoint information d to the broadcast terminal 200 at the time when the ts n1 is received, the controller 310 simultaneously broadcasts the broadcast viewpoint information on the broadcast screen of the display unit 350. (d) is displayed at a predetermined time interval (1 second) (S540).

In this case, the user may start broadcasting when the broadcast waiting time becomes zero while viewing the broadcast waiting time information displayed on the display unit 250. .

The control unit 210 determines whether the broadcast start time has come (S550). That is, it is determined whether the broadcast waiting time becomes zero (S550).

If the broadcast start time is reached, the controller 210 displays that the broadcast is in progress and the user starts broadcasting (S560).

The process of broadcasting through a mobile through the broadcast synchronization system with the signal synchronization can be applied to a general broadcast where a delay occurs between a transmitter and a receiver as necessary.

In the above process, an appropriate broadcast preparation time can be provided to the broadcast terminal, and the broadcast sender can set a more accurate broadcast start time by looking at the countdown signal up to the start time appearing on the screen of the broadcast terminal.

In addition, it is possible to provide more accurate broadcasting through the mobile terminal and to support smooth communication between the broadcast transmitter and the operator of the broadcast control system.

A communication method between the broadcast terminal, the broadcast receiving terminal, and the broadcast control system having such a configuration will be described below. Since the broadcast terminal has already been described, it will be mainly described here.

7 and 8 are views illustrating a communication method between a broadcast receiving terminal, a broadcast terminal, and a broadcast control system according to an embodiment of the present invention, and FIG. 9 shows a broadcast control method of a broadcast receiving terminal according to an embodiment of the present invention. This is a flow chart.

7 to 9, first, the broadcast terminal 200 transmits communication information to the broadcast receiving terminal 400 and the broadcast control system 300 according to a user's selection. Here, the communication information may be test broadcast information or may be a synchronization signal sent in advance before broadcasting (S910).

As shown in FIG. 7, in the broadcast reception terminal 400, the broadcast terminal 200, and the broadcast control system 300, time stamps (ts) are stored in the storage units 240, 340, and 440 in respective video and audio signals. Will be recorded. In addition, these images have a time delay due to the characteristics of the network 100 and the buffering of the broadcast control system 300, and the delayed screen is displayed on each of the display units 250, 350, and 450.

As a result, the broadcast controller requests a broadcast preparation by viewing the delayed screen displayed on the display unit 340 of the broadcast control system 300. In addition, since the transmission signal of the broadcast controller is transmitted to the broadcast terminal only through the network, time delay occurs again.

Therefore, in view of such a point, when the broadcast control system 300 sends a signal to the broadcast terminal 200, the broadcast time point information d must satisfy the condition of Equation 1 above.

In this state of communication, the broadcast control system 300 transmits the broadcast time information d and the current time ts n1 together to the broadcast terminal 200 and the broadcast receiving terminal 400 as broadcast start information. Referring to FIG. 7, the communication unit 330 transmits ts n1, which is the last time when a signal occurs together with the broadcast time information d.

On the other hand, the control unit 410 of the broadcast receiving terminal 400 determines whether the user selected the viewing wait time display function using the function key of the input unit 460 (S920).

The viewing waiting time display function is selected, the communication unit 430 of the broadcast receiving terminal 400 receives the broadcast start information, and the control unit 410 receives the received signal (S930).

Then, the control unit 410 compares the broadcast start information with the current time to calculate the viewing waiting time, which is the remaining time until the broadcasting start time (S940), and calculates the calculated viewing waiting time at a predetermined time interval (1 second unit). The display unit 450 displays the display unit 450 at operation S950.

Here, the controller 410 calculates the viewing standby time d2 to be expressed on the display unit 250 using the broadcast time information d, the time ts n3 at the time of receiving the signal, and the transmission time ts n1. Calculate as shown in Equation 3.

d2 is waiting time for watching, d is broadcasting time information, and ts n3 is signal receiving time

ts n1 is a signal transmission time sent by the broadcast control system.

If necessary, ts n3 may use ts of the most recent video or audio played at the time of receiving a signal from the broadcast receiving terminal, and ts n1 is a time sent by the broadcast control system and played at the time of sending a control signal from the broadcast control system. You can also use the ts of the most recent video or audio.

Thereafter, the display unit 250 displays the calculated viewing waiting time d2 on the screen at a predetermined time interval (1 second).

Meanwhile, while the broadcast control system 300 transmits the desired broadcast time information d to the broadcast receiving terminal 400 at the time when the ts n1 is received, the controller 310 simultaneously broadcasts the broadcast time on the broadcast screen of the display 350. The information d is displayed at regular intervals (1 second).

In this case, the broadcast receiver may watch the corresponding broadcast at a time when the viewing waiting time becomes zero while viewing the viewing waiting time information displayed on the display unit 450.

In the above process, an appropriate broadcast preparation time can be provided to the broadcast terminal, and the broadcast sender can set a more accurate broadcast start time by looking at the countdown signal up to the start time appearing on the screen of the broadcast terminal.

In the above process, a practical example is described for understanding as follows.

Referring to FIG. 8, it is assumed that a transmission interval of each signal is 1 second, and a time is determined based on the broadcast terminal 200 at the time of the first communication connection. When the broadcast terminal 200 and the broadcast receiving terminal 400 receive the broadcast time information d from the broadcast control system 300, respectively, the broadcast waiting time d1 and the viewing wait time d2 are calculated. Same as

Broadcast waiting time referring to Equation 2,

d1 = d-(ts n2-ts n1) = 7-(ts9-ts5) = 7-4 = 3 (seconds)

For viewing waiting time, refer to Equation 3,

d2 = d-(ts n3-ts n1) = 7-(ts6-ts5) = 7-1 = 6 (seconds)

.

The difference between the broadcast waiting time and the viewing waiting time may occur due to a difference between the place or the network 100, and the difference may vary.

As described above, according to the embodiment of the present invention, a broadcast preparation time may be provided to a broadcast sender in a broadcast system through a mobile terminal, and the broadcast sender may adjust a more accurate broadcast time by looking at a signal appearing on the screen, and the broadcast receiver may also The terminal can receive a more accurate broadcast, and if necessary, the broadcast sender, the broadcast controller and the broadcast receiver can support smooth communication.

The embodiments of the present invention described above are not implemented only through the apparatus and the method, but may be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded. Implementation can be easily implemented by those skilled in the art from the description of the above-described embodiments.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
