Abstract:
1. A method for simulating a video disc player in a computing device for testing firmware of the video disc player before hardware of the video disc player is available, the method comprising the steps of: loading firmware designed for controlling a video disc player to execute in an operating system of the computing device, wherein the firmware and hardware of the video disc player are developed separately and the firmware is available before the hardware; extracting a set of compressed data from a storage device for storing compressed data in the computing device; according to the firmware, selecting a decompressing program for decompressing the format of the set of compressed data from the operating system; according to the firmware, executing the decompressing program to decompress the set of compressed data into a set of decompressed data; according to the firmware, transforming the format of the set of decompressed data into the format of a set of output data recognizable to the operating system; and the operating system transmitting the set of output data to an output device to play the set of output data; wherein during firmware steps the operating system operates according to receiving at least one output signal comprising decompressed data from the firmware, and then transmits at least one receiving signal to the firmware.
