  • Publication number: 20070268267
    Abstract: A transmission apparatus and a transmission method are disclosed. The transmission apparatus comprises a handwritten input unit, a processing unit and an execution unit. The handwritten input unit is provided with a handwritten screen for continuously inputting a plurality of handwritten scripts or at least one handwritten pattern. The processing unit then converts the handwritten scripts into a string of pluralized script patterns. The script patterns are shrunk and transformed into a string of pluralized micro-patterns sequentially. Alternatively, the foregoing handwritten patterns are converted into a command instruction. The execution unit then transmits the micro-patterns to an external receiving end sequentially. Alternatively, a corresponding program is then executed based on the command instruction.
