Abstract: A mode decision system and method for motion vector fine search. Each macroblock in a frame has a pre-determined clock number. The system includes a first subtractor, an operation level generator and a determinator. The first subtractor has a first input terminal to receive a clock number and a second input terminal to receive the pre-determined clock number in order to subtract the clock number from the pre-determined clock number and accordingly generate a clock difference. The operation level generator is connected to the first subtractor in order to generate an operation level based on the clock difference. The determinator selects one or more modes in accordance with the operation level and accordingly performs the fine search on the macroblock.

Abstract: A video decoding and transcoding method and system, which decodes, displays and transcodes a video stream. When a previous frame is completely decoded, a decoding procedure checks whether a frame buffer assigned is usable. When the frame buffer is usable, a current frame is decoded to produce a decoded frame and temporarily store the decoded frame in the frame buffer, and a frame flag corresponding to the frame buffer is set. When a previous field is completely displayed, a displaying procedure checks whether the frame buffer temporarily stores the decoded frame. When the frame buffer temporarily stores the decoded frame, the decoded frame is read and displayed. When the previous frame is completely decoded, a transcoding procedure checks whether the frame buffer temporarily stores the decoded frame. When the frame buffer temporarily stores the decoded frame, the decoded frame is read and transcoded.

Abstract: A method and an apparatus for saving image data are disclosed. This method adopts a pixel processor to separate the pixel values of an image data into a plurality of pixel groups according to the highest sub-sample rate and the data width of the memory. Then, those pixel groups are stored in different memory blocks of the memory after being recombined such that sub-sample images can be efficiently obtained under a condition that only full-resolution image is stored, thus improving disadvantage of storing low-resolution image separately in prior art. Besides, the data of those pixel groups are arranged alternately such that every memory block can be opened evenly and alternately when storing/reading sub-sample and original image, thus enhancing the efficiency of memory use.

Abstract: A file system for file sharing includes a web server that creates a temporary directory for each session between the web server and a client computer. When the client computer requests a file located in a file server, the web server creates a symbolic link to the file in the temporary directory and a web page including an URL to the symbolic link. The web server transmits the web page, and therefore the file, to the client computer. Client computer can also upload files to the web server. The web server saves the uploaded files to the temporary directory and then moves the files to the file server. At the end of the session, the web server deletes the temporary directory. Thus, files are not saved on the web server and therefore not accessible to others from the Internet. In this file system, file and directory names are orderly incremented in the file server to simplify the back up process of the file server.
