Claim:
A content distribution system for distributing content to a terminal through a network comprising: a distribution server for preliminarily storing multiple contents each in a compression coded bit stream and providing a selected one of the multiple contents in response to selection of content by the terminal and another one of the multiple contents sequentially following the selected one; and a conversion device capable of converting a compressed coded bit stream to another compressed coded bit stream, wherein the conversion device, in response to reception of the selected one from the distribution server, preliminarily notifies the terminal of decoding information of the selected one, transmits to the terminal the selected one in a compressed bit stream in syntax according to the decoding information of the selected one, and transmits to the terminal the another one of the multiple contents, sequentially following the selected one, in a compressed coded bit stream in syntax according to the decoding information of the selected one that has been preliminarily notified to the terminal, when the decoding information of the another one of the multiple contents does not match the decoding information of the selected one that has been preliminarily notified to the terminal, while transmits the another one of the multiple contents without syntax conversion when the decoding information of the another one of the multiple contents matches the decoding information of the selected one that has been preliminarily notified to the terminal, and wherein the another one of the multiple contents comprises an advertisement content.
