摘要:
A controller and a method of updating parameters on the same. The controller includes an embedded non-volatile memory, a programming circuit, an embedded SRAM, a MCU (Micro Computer Unit), and a memory controller. The embedded non-volatile memory has a program code block for storing program codes to be executed by the MCU, and a data block for storing the parameters. The MCU writes the parameters into the data block of the flash memory through the memory controller, or reads data in the data block of the non-volatile memory through the memory controller. Because the controller does not need to employ an external EEPROM, the cost can be reduced and the speed for accessing the parameters can be increased.

A video processing method utilized in a video data processing device for processing video data is disclosed. The video data includes at least a first video data set, and the video data processing device has a memory and a video decoder. The method includes utilizing the video decoder to decode the video data for generating a display data set, driving the video decoder to select a specific video data set from the first video data set wherein the display data set does not have display data corresponding to the specific video data set, and utilizing the memory to store the display data.

A VBI receiver and method is disclosed. The receiver includes an over-sampling circuit, a transition detector, a data selector, and a data output device. The over-sampling circuit is for over-sampling VBI data and outputting and over-sampled signal. The transition detector is for detecting the transition of the over-sampled signal and outputting a transition signal representing the transition position. The data selector is for recording the transition signal and outputting a position signal according to the transition signal and at least a previous transition signal. The data output device outputs digital output data from the over-sampled signal according to the position signal.

The invention provides a digital television tuner having at least two brances that receive a radio frequency signal, wherein the radio frequency signal carries M channels (M is a positive integer). A target image data is generated in real time since at least one of the branches pre-extracts the image compression data of the next channel to be switched to.

An Audio Codec which comprises a power selecting circuit an audio compiler circuit and a control amplifier circuit. The power selecting circuit receives at least a primary power source and an auxiliary power source and outputs a working power selected from the power sources. The auxiliary power source is selected and output to the control amplifier circuit only when the computer is at a power-off status. When the computer is power-on, the primary power source will be selected and output to both the audio compiler circuit and the control amplifier circuit. Therefore, the Audio Codec of the present invention only needs one set of internally furnished control amplifier circuit to both operate on the normal power-on status and perform the Power OFF CD function.

A multi-jack detector for detecting states of a plurality of jacks. Each jack comprises a first switch having a first normally closed terminal and a first output terminal. The multi-jack detector comprises a plurality of bias resistors each coupled to one of the first output terminals, respectively; a control unit for determining the states of the plurality of jacks; wherein the first normally closed terminals are commonly coupled to a first node and the control unit determines the states of the plurality of jacks according to a voltage at the first node. Because the voltage at the first node is different for each state of the jacks, the detector can detects the states of the jacks using a single I/O pin.
