A method of downloading a multimedia content from a content server to a client through a wireless communication network is provided. The multimedia content is subdivided into a plurality of chunks and for each chunk the content server has at least two corresponding versions thereof encoded with different encoding rates. The method includes having the client send a first request of a first version of a corresponding requested chunk, and having a proxy server intercept the first request to generate a second request of a second version of the requested chunk. The method also includes having the proxy server send the second request to the content server in place of the first request, and having the content server send the second version to the client. The second request is generated based on the amount of information content of the versions of said requested chunk.
