Abstract: A multi-format video decoder includes a bitstream buffer, a system controller, a bitstream decoding unit, an intra mode decoding unit and a shared prediction module. The system controller selectively generates a first control signal or a second control signal according to a video bitstream. The bitstream decoding unit generates a decoding information signal according to the video bitstream when receiving the first control signal. The intra mode decoding unit generates an intra mode signal when receiving the second control signal. The shared prediction module performs an AC/DC prediction upon a current block of the video bitstream to generate a current first prediction result according to the decoding information signal and performs an intra prediction upon the current block to generate a current second prediction result according to the intra mode signal. The shared prediction module includes shared components being utilized in the AC/DC prediction and the intra prediction.

Abstract: A decision sequence generating method and an associated receiver with a decision feedback equalizer (DFE) are provided. The receiver can mitigate multi-path distortion generated when data is transmitted through a multi-path channel, wherein the data is encoded into codewords, each of which comprises N chips. The receiver comprises a decision generator for generating N−1 chip decisions corresponding to first N−1 chips of a received codeword and for producing a codeword decision corresponding to the whole received codeword; and a feedback filter for reconstructing post-cursor section of the multi-path channel impulse response. The decision sequence generating method comprises sending the N−1 chip decisions into the feedback filter in order, producing the codeword decision after collecting all N chips of the received codeword, and then providing the codeword decision to the feedback filter to replace the N−1 chip decisions sent previously, thereby reconstructing the post-cursor section of the channel impulse response with more confidence.
