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.

Multi-format video decoder and related decoding method

A signal processing device with high efficiency of teletext information processing is provided. The signal processing device is configured to receive and encode a transport stream for display, wherein the transport stream provides teletext information associated with a plurality of teletext lines and video information associated with a plurality of video lines. The video signal processing device includes a memory configured to store line enable signals and line data associated with the teletext lines and the video lines, a VBI controller coupled to the memory, configured to read the memory to obtain the line data associated with enabled teletext lines of the teletext lines, and an TV encoder coupled to the VBI controller, configured to receive and encode the line data associated with the enabled teletext lines for display.
