An encoder. A first encoding unit discrete cosine transforms an input frame, quantizes the transformation result, and generates a first frame according to a motion vector. The first encoding unit includes a first feedback unit dequantizing the transformation result, generating a processing signal and a first reconstruction signal according to the dequantization result, and re-quantizing the processing signal to generate a requantization signal. A second encoding unit encodes according to the first reconstruction signal to generate a second frame and an encoding signal. The third encoding unit generates a third frame according to the encoding signal and the re-quantization signal.

An optical pickup module reading data along a track-seeking path is provided. The optical pickup module comprises a base, a first fastening component, a first shaft and an optical pickup head. The base has a fastening plate and the fastening plate has a sliding hole, wherein an included angle is formed between the extension direction of the sliding hole and the track-seeking path. Since the included angle is formed between the extension direction of the sliding hole and the track-seeking path, one end of the first shaft can be easily inserted into the sliding hole of the fastening plate along the extension direction of the sliding hole. Then, another end of the first shaft is assembled with the first fastening component so that the first shaft is parallel to the track-seeking path. At the same time, one end of the first shaft tightly fits to the fastening plate.

A universal printing method for printing out non-image file documents is executed by installing a universal printer driver on a smart phone or a PDA that supports PictBridge, and includes activating an application program and opening a non-image file document, converting the non-image file document into at least one image file through the driver and an OS rendering module, and finally transmitting the at least one image file to a printing device through PictBridge. The method permits conversion of multiple pages of non-image file documents that originally cannot be printed using PictBridge to image files for printing by a printing device supporting PictBridge.
