Content transmission method and system supporting handover, and computer-readable recording medium

According to one aspect of the present invention, the content transmission method supporting handover includes: (a) compressing, at a compressor, content transmitted from a server and transmitting the compressed content to a de-compressor if a request for changing to a compression mode is received; and (b) transmitting, at a compressor, content transmitted from a server without compression to a client or another decompressor connected to the client after a handover occurs if the handover occurs at the client.
