Disadvantages and risks associated with live broadcasting

Live broadcasting has a number of disadvantages. As a typical thing, due to its characteristics,accidentOr trouble (Broadcasting accidentThe first side is that there is always the risk of ). Also, due to unexpected unexpected situations and equipment operation mistakes, video and audio that should not be broadcast may flow, or the words and actions of the performers and staff may flow, so it should not be broadcast by nature. There is a risk that the image of the program or the performer may be flawed if the unsuitable carelessness, unscrupulousness, unrest, and shameful content are transmitted to a huge number of viewers and listeners.2004 IsNFLThe final matchSuper bowl OfHalf time showAtJanet JacksonCaused an accident in which the co-star exposed his chest[Annotation 1].. in JapanAkiko MatsumotoThere is a case. See her link for details.

Even in the entertainment world, there is no way to stop the defect of the talent image due to the carelessness of the belonging talents, the remarkably light speech, and the action if it is a live broadcast, but on the other hand, the recorded program is checked in advance before broadcast and prevented by editing. Can doRisk managementThere are many merits, and now there are many entertainment offices that are reluctant to appear on live broadcasts. In addition, there are entertainment offices and talents who take the stance of live broadcasting NG due to factors such as the personality, behavior and sales strategy of the talents, or the condition that co-starring with a specific talent is OK only for pre-recorded programs.

Live broadcasting has the property that it is sent to the unspecified majority immediately without being edited. Therefore, someThose with political purposes,Environmental protection-Cultural propertyProtected/historicBuildingVarious activists such as the preservation movement have the intention of trying to force themselves to publicize the assertions of themselves and their organizations, or to interfere with the broadcasting of content that is not convenient for them,PurposelyMay attempt to inject live broadcasts into the field, interrupting the broadcast or even interrupting live broadcasts.Business interruptionActions have also been triggered in the east and west of the western world.

Likewise an outsiderWild horseIs also sometimes a threat to live broadcasts. Especially in the case of TV, the scene and jurisdiction of an event or accident with high social attentionPolice stationIn live broadcasting from the vicinity, etc., a large number of Nojima horses gathered for the purpose of "reflective" in the relay image for fun, and in the first place distant for self-revealment by "reflective" There are many cases where people who go to the incident site or the relay site also appear, and the relay site becomes confused by the number of people themselves and it becomes impossible to live broadcast. OnceNews program,Wide showIn the era when many street interviews with the general public were performed live on live broadcasts, etc., people who aimed to be interviewed on the streets by pretending to be local residents or passing streets and those who were intended to be shown on the TV screen, street interviews Of the broadcasting station that the staff may receive as a reward according tonoveltyPeople who chase the media for the purpose of collecting goods appeared, around the scene of the incident, and the relay point of the so-called "fixed point".[Annotation 2] When I went to such places, I was prowling around the media coverage.

This was originally intended to be used as an effect device for live broadcast program production, but because of its function, it is also effective as one of the measures that are premised on the occurrence of an unexpected situation in live broadcast.

Live broadcast in Japan


At the beginning of broadcasting, VTR equipment/recording media were very expensive and the operating cost of recording equipment was high,Music programNot to mention dramatheaterEven in such cases, live broadcasting was quite natural, and the performers were constantly strained to cope with sudden events.[4]However, due to advances in recording technologyEditIf it becomes possible, the live broadcasting that is high risk for the sender can be obtained only by the live broadcasting (so-calledFeeling of live) Has become limited to when you want the feeling of tension or peculiar to live broadcasting. In fact, it's called LIVE in English.

Live broadcast1980 eraSince then, it has been decreasing. In the background, in addition to the advances in equipment and technology required for recording, cost reduction of tapes, 1-2 tapes at one timeRecordingIt is influential that they are more efficient. For broadcasting stations, there are circumstances in which it is easy to adjust the schedule when casting performers, and it is easy to deal with sudden troubles such as suddenly becoming unable to perform. Meanwhile, being castEntertainment officeFor the side as well, the more recordings that can be obtained from live broadcasting, the more jobs that can be obtained, the easier it is to make a profit, and the more time is available in terms of schedule. Therefore, it is a big plus for both broadcasting stations and entertainment offices. Also, for the program staff who participate in the recording, live broadcasting, which is always tense in anticipation of a situation where a sudden accident flows through the screen, has a heavy mental burden, and a recorded program that can be edited is riskier. There are few things.

In addition, there are cases where the next broadcast is recorded before the start of the live broadcast or after the end of the live broadcast (this is also a de facto two shots) even though the main broadcast is the live broadcast.Super JOCKEY"Such). About this, the schedule of the performers and staff, and production cost savings (reducing the cost of one live broadcast by shooting two) can be done in most cases.

1990 eraSince then, as the electronic control of various editing equipment has become more sophisticated, the number of cases where a program that should have been started by touching live broadcasting every week was changed to recorded broadcasting only a few times. For example,Nippon TVseries"Minna TV],Fuji Television Network, Incseries"Tokudane! GO-Guy!"and so on. LowAudience ratingIt is often seen in programs where the schedule of busy performers cannot be adjusted.

NHKThen, I often reduce live programs as much as possible on public holidays (this is not the case when serious news occurs).Suzuki YujiIs "Work way reformIt's hard to come up with a regular live show (NHK) on public holidays. The majority of commercial broadcasters are subcontractors... However, the wave of "work style reform" is rushing to the private sector. I may review it."[5].

Similarly, in NHK, due to the nature of the absence of commercials, there are cases where performers make facial expressions and comment on the fronting program at the beginning of the program when the backing program is live when switching programs. Even in commercial broadcastingStepreWhen performing program switching (without CM), the same effect may be performed. In addition, when live broadcast programs are continuous, there are cases in which performers such as crosstalk are performed between the performers of both programs.
