摘要： A video compression method compresses the capture video raw data into the 1st compression format and records the image patter complexity of each frame of a predetermined amount of video frames. The information of the image pattern complexity is used to determine the bit rate of each frame for the 2nd time of the video compression. For saving the image buffer size and speeding up the accessing time, a lossless and near lossless video compression algorithm is applied to the 1st video compression algorithm.

摘要： A video compression, transmission and decoding procedure includes: reducing the image data by calculating the average of a predetermined number of pixels, calculating the DCT coefficients and dividing DCT coefficients by predetermined matrix of values, and applying fixed length of code to represent the DCT coefficients. Low frequency DCT coefficients of each block of pixels are saved in a temporary storage device, should the data loss or damage happened during transmission, the low frequency DCT coefficients of the corresponding block are decoded to represent the lost data. In audio compression and transmission point, a group of audio samples are separated to be at least two sub-groups of audio samples, should any audio sample is lost or damaged, the interpolated value of the nearest adjacent samples of at least one sub-group is used to represent the lost or damaged audio sample.

摘要： A codec device is disposed in a display control device for instantly supplying decompressed image data to manipulating devices in the display control chip. Reference images are stored in compressed format after instantly compressed by the codec device. In addition, MSB portions and LSB portions are separately compressed for gaining higher compression ratio. Predication of the pixel value is also modified in variable length coding. On-chip line buffer is also applied with the instant compression mechanism. Fixed compression ratio is predetermined to actually downsize the chip design for the worst case.

摘要： An image compression method for compressing groups of pixel data, including the following steps: MSB portions and LSB portions of the pixel data are compressed separately. Further, the LSB portions are grouped according to their associated MSB portions so that similar pixels are compressed together to gain higher a compression ratio. Some LSB portions are truncated to ensure a compression ratio. When performing compression, enhanced variable-length coding is adopted that predicts more accurate dividers by considering weighted combination of adjacent pixels. The quotient of each groups of compression portion is predicted and coded accordingly.

摘要： The present invention provides method and apparatus of a fast DCT implementation. DCT calculation is combined with quantization scales by a procedure of pre-processing. During DCT coefficient calculation, only non-zero coefficients are calculated. If pixel variance range is smaller than a first predetermined threshold, a predetermined lookup table is compared to decide the DCT coefficients. When a pixel variance range of a block pixels is within the second threshold, coupled with the quantization scales, the pre-processing determines the amount of non-zero DCT coefficients need to be calculated. Only a limited amount of LSB bits within a block is applied in the calculation of DCT coefficients. A previously saved pixel with equal or closest pixel value is used to replace the operation of current pixel's multiplication.

摘要： A multimedia system including an audio/video decoder/decompresser for decoding/decompressing a compressed encoded audio/video data stream to generate video images for display and audio signals for audible reproduction. The multimedia system includes an integrated system and video decoder with an audio/video synchronization circuit for substantially synchronizing the display of video images with audio playback. In addition, a step control is provided to allow for viewing of video images on a frame-by frame basis or to freeze or play video in slow motion. When step control is activated, audio output is muted. Audio data corresponding to displayed video is transmitted to the muted audio decoder. An internal system clock may be suppressed to the system clock counter. An external CPU may provide system clock start times corresponding to video frames to be displayed. The external CPU may increment the system clock counter by a an amount corresponding to the difference between a successive frame or number of frames. When nominal playback is resumes, the audio and video data streams are substantially in synchronization.

摘要： An automatic bus identification circuit is provided in a device to reliably detect system bus type on power up despite fluctuations in supply voltage. A system bus type signal is received over a multi-function input line at a first input and a reset signal received over a set line at a second input. A bus type identification circuitry is provided to latch the system bus type signal upon power up and continuously output this signal as a system bus type identification signal. To prevent the influence of disturbances in the power supply upon power-up, a flip-flip is provided to output a logic signal in response to a system reset signal. The flip-flop is configured with a strong-N type inverter to insure that the flip-flop will be set into a grounded state as power is applied to the circuit, despite the influence of transient power supply voltages.
