An apparatus for transmitting user data to a server system including one or more servers includes a content encoder for encoding a plurality of portions of the user data to obtain a first data stream, wherein the content encoder is configured to encode each of the plurality of portions with a bandwidth-dependent quality which depends on a bandwidth that is available for transmitting the first data stream from the apparatus to the server system, and includes a transmitter for transmitting the first data stream from the apparatus to the server system. The content encoder is configured to encode two or more of the plurality of portions of the user data to obtain a second data stream, wherein the content encoder is configured to encode each of the two or more of the plurality of portions with a predefined quality.
