The invention discloses a transmission method. To overcome the disadvantages that: in the multi-media display system in the prior art, the difference of transmission regions of multi-media data information can inevitably affect the transmission speed of the network to cause the interruption or delay of the playing during the transmission of the data information, as well as the streaming media transmission mode fails to work when the network is disconnected, the invention designs a transmission method that the multimedia information is transmitted by means of the network, a server side uploads the multimedia data information to the network directly in the form of a multimedia compressed file, the multimedia data information is made a compression packing into a data packet through an IP transmission layer of the network TCP/IP protocol and then is sent to a designated client receiving end, the client receiving end makes a one-time download to the multimedia data information and prepares for playing, the data packet is decompressed after the one-time download is finished, and a multimedia player is used to play the multimedia information. The information display mode can allow the client side not to be always connected with the server and reduces the dependency to the network when the multimedia data information is transmitted in the streaming media mode.
