Abstract: An electronic module is provided, which includes a first package and a second package stacked on the first package. The first package has an encapsulant and an electronic element embedded in the encapsulant. The second package has an insulating layer and an antenna structure formed on and extending through the insulating layer. The insulating layer is bonded to the encapsulant with the antenna structure being electrically connected to the electronic element. Since the second package having the antenna structure is stacked on the first package, the invention eliminates the need to increase the area of the first package for mounting the antenna structure and hence allows the electronic module to meet the miniaturization requirement.

Abstract: This invention provides a method and a system to read and buffer an audio data file from an optical storage medium into a buffer memory. The data file comprises blocks sequentially stored in the medium. Each block comprises a subcode block with encoded subcodes and a corresponding main data block with encoded audio data. The method first designates a starting block where buffering starts and searches for the starting block in the blocks. After the starting block is searched, trigger a main data block decoding procedure to decode the starting block and main data blocks in later blocks. According to the timing when the main data block decoding procedure is triggered, decide the timing to trigger buffering the decoded subcodes to the buffer memory. Therefore, the subcodes and corresponding audio data belonging to the same block before decoding can be buffered into the same buffer unit after decoding.

Abstract: The present invention is a data buffering system for buffering information from an optical recording medium into a buffer memory. The information comprises a main data and a subcode. The system comprises a main target comparator, a correction target comparator and a transfer/buffer module. The main target comparator selects a start main data frame of the main data, and triggers a main data transferring procedure when detecting the start main data frame. The correction target comparator gets a correction main data frame by adding an additional value to the start main data frame, and trigger a subcode transferring procedure when detecting the correction main data frame. The transfer/buffer module transfers and buffers the subcode to the buffer memory and the main data according to the subcode transferring procedure and the main data transferring procedure, respectively.

Abstract: A method for using a compact disc decoder to correct a code error in digital data read out from a compact disc includes extracting address data out of at least one sector read from the compact disc, and using an error detection circuit to read a condition of an input error flag corresponding to the address data of the sector, wherein if the condition of the input error flag indicates that the address data contains an error, then the extracting circuit extracts address data of another sector. The method also includes when the input error flag indicates that no error is present in the address data of the sector, the sector is referred to as a first sector, and the selection circuit selects address data of the first sector without referring to address data of any sectors read before the first sector.
