This invention discloses a new media storing and publishing system. The system comprises a living broadcast mode and a video-on-demand mode; in the living broadcast mode, streams of television station signals are encoded and the streams are pushed to a streaming media server; living broadcast streams on the streaming media server are referenced by a WEB; thus, a user can see video real-time living broadcast channels of television stations through a PC (Personal computer), a television and a handheld terminal; in the video-on-demand mode, video-on-demand contents needed to be published by the television stations are uploaded to the new media storing and publishing system to be transcoded and published in a manner of multiscreen displaying; video-on-demand file streams on the streaming media server are referenced by the WEB; and thus, the user can see the video-on-demand of the television stations through the PC, the television and the handheld terminal. By adopting the system provided by the invention, the problem that small and medium-sized television stations can only deploy a new media encoder server, a living broadcast publishing server, a video-on-demand publishing server and a storing server separately is effectively solved; the promotion range and the promotion channel of a local television station can be extended; and thus, the invested cost for establishing the new media for the television stations can be reduced.
