放送 and 配信: School Announcements and Delivery to Members
Compare a festival broadcast and a school announcement with a lecture video for members and a notice sent to subscribers. Follow the content, intended audience, and future or past action.
A program broadcast and a school announcement
放送 (ほうそう) means broadcast. 「地域の祭りを紹介する番組が放送された。」 — “A program introducing the local festival was broadcast.” The content broadcast was a program introducing the local festival.
「校内放送で集合時間を知らせた。」 — “The gathering time was announced over the school public-address system.” The gathering time was announced over the school public-address system. This example also uses 放送, so the word is not restricted here to television programs.
A video for members and a notice for subscribers
配信 (はいしん) means content delivery or streaming. 「講演の映像を会員向けに配信する。」 — “The lecture video will be streamed to members.” The English quotation presents streaming the lecture video to members as a future action; it does not report a completed release to the general public.
「店は休業のお知らせを登録者に配信した。」 — “The store sent its closure notice to subscribers.” The store sent a closure notice to subscribers. The delivered content is a notice, rather than a video. Sending it does not establish that every subscriber read it or that the store shut down permanently.
Read the content and recipient together
The 放送 examples concern a program and a school announcement. The 配信 examples concern a lecture video and a closure notice. The content is not divided into video for one word and announcements for the other.
会員向け and 登録者に identify the targeted recipients. Keep streaming to members and sending a notice to subscribers within those scopes, without expanding them into a general release or completed viewing by everyone. Also distinguish the future streaming statement from the past sending action.
Does 「講演の映像を会員向けに配信する。」 say that the video has already been released to the entire general public?
Show the answer and why
No. The video is intended for delivery to members, and the English example says it will be streamed. The subscriber notice likewise has its own content and recipients. Neither sentence adds a result in which everyone has watched or read what was delivered.
