A method provides efficient data transmission between an input-output card with an add-on memory card and a host system. The input-output card carrying an inserted memory card is connected with the host system to improve the mechanical strength of the arrangement. An input-output controller on the input-output card controls a switch that switches between data buses. The memory card and the input-output card optionally share all data buses of the input-output card to transmit data with the host system, directly transmit data between each other, or respectively use a portion of them to achieve a better transmitting efficiency.

The present invention relates to an apparatus and method for analyzing the read-out signal of an optical storage media and is especially suitable for the HF signal read from the digital video disk (DVD), wherein the HF signal comprises many different signals whose periods are integer times of the system period. The present apparatus can be used to record the maximum or minimum values of specific period of signals for further statistical analyses. Furthermore, the AC and DC components of the HF signal can be processed independently and the results will be combined together for further processes. Therefore, it only takes moderate memory capacity and acquisition time to obtain accurate maximum or minimum values of the specific period of signals.
