Description

Multi channel preview system of Internet Broadcasting and method

The present invention relates to an internet broadcasting system and a broadcasting method capable of multi-channel viewing. Each server has a server for each region, and each server encodes and supplies a broadcasting channel of the region, and each server decodes the encoded data to the subscriber. The present invention relates to a multi-channel simultaneous internet broadcasting system and a broadcasting method for simultaneously viewing a multi-channel including a broadcasting channel.

In general, as Internet use becomes more active, in addition to watching TV through a TV set, a TV broadcast channel may be received through an internet network. However, the Internet broadcasting method does not receive broadcast signals through the existing airwaves as it is, but separately clicks a broadcast video file produced by each broadcasting station and media player (Microsoft's media player or a similarly developed media player). Watching through the situation.

On the other hand, general cable TV viewers watch TV by wire, or in order for a computer user to watch TV broadcast through a monitor, a separate TV card is used to convert the monitor into a scan mode and watch it on a monitor.

In all of these cases, only one channel can be viewed simultaneously, so in order to watch other channels freely like a regular TV, it is necessary to change the Internet address. In the case of using the TV card, there is a problem in that the TV card must be purchased and installed, and the image quality is also low, and thus a clear screen cannot be provided.

The present invention is to solve this problem, an object of the present invention is to provide an Internet broadcast that allows viewing in the form of multi-channel TV channel broadcasting in the form of multi-channel preview.

Another object of the present invention is to provide a viewer who can watch a multi-channel broadcast, and the viewer is to provide an internet broadcast to facilitate the viewer's channel selection by making the selection screen larger and the non-selection screen smaller.

It is still another object of the present invention to provide an internet broadcast that allows seamless viewing by decoding the encoded television signal, converting it into a receivable size, and transmitting the encoded television signal.

5 is a flowchart of the present invention,

In the first and second server using the Internet network, the user is registered as a member and provides a multi-channel viewing viewer,

A first step (S1) of simultaneously encoding source data for wire broadcasting of various broadcasting stations by the first or second server (10 or 20);

A second step (S2) of receiving and simultaneously decoding the source data encoded by the second or first server 20 or 10;

A third step (S3) of checking a line speed (bps) of the user during user connection authentication; And

A fourth process S4 of selecting the size of the decoded data according to the line speed and transmitting the image to be viewed through the multi-channel viewer is performed sequentially.

Following the fourth step S4, a fifth step S5 of checking a line of a receiving subscriber at a predetermined period and variably transmitting the screen size of the decoded data may be additionally performed.

According to the present invention configured as described above, a server having a wire broadcasting right can be used as a server operator by obtaining permission of a broadcasting station of a corresponding region or country from each server 10, 20. The following presupposes and describes the state with such authority. Each server (10, 20) should be provided with an encoder (13, 23) for receiving and encoding television channel data over a wired network, and a decoder (12, 22) for decoding to be viewed when sent to the subscriber, and the Internet network When the viewer joins the membership through (membership and usage fee is used as it is, the description thereof is omitted), the server provides a multi-channel viewing viewer 30 that allows the user to view the program. . Then, viewers can download from their computer and install it. To this end, the present invention receives broadcast data of TV broadcast stations in the region of the first server 10 and the second server 20 and transmits the broadcast data to the other party, and each server 10, 20 simultaneously or selectively performs a channel according to mutual agreement. Perform the services provided. That is, the first server 10 receives and encodes broadcast data of the broadcast station B1 by wire. The second server 20 also receives broadcast data of the broadcasting station B2 by wire and also encodes it. Each server 10 or 20 has agreed to share each channel with each other, and accordingly, the servers 10 and 20 simultaneously display the channels of the counterpart broadcasting stations. Therefore, in the region of the first server 10, the channel of each broadcasting station TV1-TVn of the broadcasting station B1 and the channel of each broadcasting station nTV of the broadcasting station B2 received from the second server 20 are simultaneously displayed. In other words, this means that you can watch both Korean and Japanese channels in Korea at the same time.

In order to enable display of a multi-channel display screen at the same time, the first play tool F1 displays a screen of each channel a1-an by dividing a general media player screen and simultaneously displays each channel a1. -an) to be displayed through the display frame (F3) to be displayed in each position corresponding to the screen. Then, the second play tool F2 is placed in the overlap layer Layer on the first play tool F1. The second play tool F2 causes the screen of the selected channel among the channels a1-an of the first play tool F1 to be displayed. Then, the channel of the main screen can be viewed through the second play tool F2, and if necessary, the screen of the other channel is a small screen, and the user selects and watches a screen suitable for the taste while watching through the display frame F3 ( Of course, the screen can be selected by clicking the screen or configuring a separate selection window). In this case, the display frame F3 may be implemented in a form representing an image or may be configured as shown in FIG. 3 to represent a channel name.

In the present invention acting as described above, each server 10, 20 performs a service by subscribing to a subscriber when the configuration as shown in FIG. 1 is performed. Even though it is difficult to expect the display of a uniform screen like the air broadcasting in a different situation, it has been solved, and it is to recognize the line speed of the user when the initial viewer is authenticated. That is, as shown in FIG. 5, each server 10 or 20 encodes the other party and / or its own broadcast channel source data signal (S1).

The encoded signal is decoded (broadcasting only the data of its own area and / or displaying the broadcasting of another area at the same time) to decode the screen size to be variable.

On the basis of the decoded screen as described above, when the user requests a connection (login to the server 10 or 20), the speed (bps) of the response (ACK) to the ACK is checked through the user's connection line ( S3) The size of the screen is determined and transmitted according to the preset speed (S4) In this case, if the screen size according to the speed is low as shown in Fig. 4 (for example, 256 Kbps), the screen size is made smaller and the speed is higher ( For example, 500Kbps) screen size can be transmitted largely, which prevents the screen from being cut due to the difference of line speed.

On the other hand, when the present invention is in a line fluctuation environment, it is better to perform the fifth step (S5), so that the change in speed is periodically checked (S51), and the response time according to the checking is checked (S52). If you change the size of the frame screen according to the checked speed, you can always display the screen without interruption.

The present invention described above is not limited to the above-described embodiments and drawings, and various permutations, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

As described above, the present invention enables the Internet user of various environments to simultaneously watch the multi-channel broadcasting of uniform image quality so as to realize the multi-channel viewing desire of the user. In addition, since various viewers can watch simultaneously through the Internet network, it is possible to meet the balance of accounting according to the server operation even if the viewership fee is low. According to the present invention, when the servers cooperate with servers in different countries, the broadcasts of the other countries can be viewed like domestic broadcasts through the Internet. In addition, the present invention is easy to select a channel by selecting in advance by watching the multi-channel even though the Internet broadcast, even if the orphan through one of the screens, the advertising effect is huge, which is advantageous to generate revenue according to the server operation.
