Abstract: A reflector and a method for improving transmission speed of video data in WAN-based data collector-server architecture are disclosed. The reflector includes a recorder for storing raw video data transmitted from the data collector, a program for trans code the raw video data into a predetermined format, and storage for storing the trans code video data. Meanwhile, the method includes the following steps: providing a plurality of the above-mentioned reflectors at the server, building a plurality of tunnels for transmitting the raw video data between the data collector and the server, transmitting the raw video data from the data collector to the server via the tunnels, storing the raw video data in the recorder at any given time, and reflecting the raw video data in the recorder from one reflector to any other reflectors at any given time.

Abstract: A method for embedding an operating system and application program into a memory apparatus. The operating system includes a boot file and a run control (RC) program and the method includes the steps as follows. First, source codes of the operating system are processed for obtaining a crunch file of the operating system by applying a crunch technique. The crunch file of the operating system is then compiled, resulting in an executable file of the operating system which is then compressed into a system compression file. Next, eliminating unnecessary comments and settings from source codes of the application program, a compact version of the application program is obtained. Following that, a program storage file is mounted as a mount point through a virtual node technique. Next, the compact version of the application program is copied to the mount point. The program storage file is then compressed into a program compression file.
