Description

TECHNICAL FIELD The present invention relates to a live distribution system, and more particularly to a two-way broadcasting system that performs live distribution via a communication line.

People are being asked to stay at home to reduce the impact of the new coronavirus (COVID-19) infection. For this reason, entertainment live performances such as sports, music, and entertainment have been canceled or postponed across the board. Therefore, companies, organizations, and individuals involved in these entertainments, as well as performers, athletes, and celebrities (hereafter referred to as performers, etc.) who are performers at the event, are in a dire financial straits.

On the other hand, the spread of COVID-19 is still unstoppable, and it is completely unknown when it will end.

During the period when people are asked to refrain from going out, it is necessary to find comfort and enjoyment through entertainment. The reality is that it is not possible to enjoy music and sports at large, medium and small live venues such as theaters and ballparks. In addition, these live venues typically have tens, hundreds, or thousands of seats, as well as multiple loudspeakers and multiple microphones. Furthermore, when a live performance is actually performed, tickets are sold to spectators, and each ticket is usually printed with the seat number in the live venue, that is, the seat number as seat information along with the name of the live venue and the date and time. ing. In this case, a charge is set for each seat according to the distance and angle to the stage in the live venue. Therefore, spectators who have purchased a ticket can view and enjoy the live performance according to the seat position in the live venue, ie, the seat number.

Live distribution using the Internet is actually performed by performers and the like. In the live distribution, the video and audio of the performers can be viewed via computers, smartphones, etc. In this case, there is also a mechanism in which the viewer can write their impressions, etc., and the written impressions, etc. are displayed on the live screen of the computer or smartphone in real time (Non-Patent Document 1).

However, the performers who perform at the live venue cannot know the reactions of the viewers in real time at the live venue. For this reason, the performers can only know the reactions of the viewers recorded after the live performance, and the performers cannot know what the reactions of the viewers are like in real time. As a result, events held without spectators often result in poor performance of the performers.

On the other hand, Patent Document 1 discloses a system for providing communication services using multimedia communication for transmitting information using a plurality of information media. Patent Literature 1 also discloses a multi-client interactive conference service that enables video and audio information conferences between a plurality of client terminals. Further, Patent Literature 1 also discloses providing a PC for transmitting a live broadcast for live broadcasting.

However, Patent Literature 1 does not consider live distribution in a non-audience state at all.

The problem to be solved is that audience-less live broadcasting cannot notify the performers of the reaction of the audience in real time, so the performers cannot necessarily concentrate on the performance, the game, and the like.

Furthermore, there is also the disadvantage that it is not economically advantageous for event operators and performers because the costs for live performances without spectators through the Internet are uncertain. In addition, the seats in the live venue are not taken into consideration for live performances without spectators through the Internet. In other words, no consideration is given to setting a fee according to the seat at the live venue and enjoying the audio and video according to the seat.
