摘要:
A method for reducing memory resource utilization is disclosed, applied to simplify address space of a table. Values stored in address fields of an original table are analyzed to determine whether logical relationship is detected between the values. If the logical relationship is detected, the values stored in the original table are classified to multiple base values and corresponding reduced values to generate a transformation table. Values with the same logical relationship for base values and the corresponding reduced values are stored in a new and equivalent address field of a reduction table.

A system and method are provided to edit interactive three-dimensional multimedia. A user interface of the system is provided with an event level template that includes event series levels with multiple event developing points. Through the user interface, multiple interactive events related to a first character of the event developing point are edited. Through a three-dimensional engine, interactive relevances are built up between interactive events and multiple materials inside one or more database. When the interactive three-dimensional multimedia with multiple materials is output, the interactive events corresponding to the event developing points are performed according to a user command. An online editing and exchanging method integrated with the system and method is also provided to share pre-edited templates on an exchange server; each of the pre-edited templates is extracted from an interactive three-dimensional multimedia pre-edited by the system and method.

A watermark coding method and its recording medium utilize image interleaving and wavelet-based transformation to enhance the robustness of the image. The watermark series to be inserted is converted, encrypted, and modulated to increase the difficulty in decoding and restoring. Finally, the watermark is distributed and hidden in various frequency bands of the image in a frequency hopping way, generating a robust watermarked image. When used in a recording medium, side information produced during coding is recorded in the lead-in area of the recording medium to reduce the chances of illegal copying.

An ultrasound receiving method is provided. N return-wave signals corresponding to N channels are respectively stored in N set of shift register arrays. Each set includes a delay filter unit and M shift registers. A delay controller is utilized to assign a set of coefficients to the delay filter unit to perform an interpolation operation on data of the M shift registers to obtain an output value. The delay controller is utilized to decide delay time of each channel according to a delay table, and accordingly to control a time multiplexer to switch and output the N output values in order. A multiplier is utilized to multiply the output value received from the time multiplexer by a weighted value corresponding to the channel to obtain a corrected value. An accumulator is utilized to accumulate the N corrected values to obtain an image value.
