    摘要: A transcoding method and transcoder A compressed bitstream of video data is received and it is determined whether a skipped block occurs in the compressed bitstream. When the skipped block occurs in the compressed bitstream, a corresponding skipped block is generated in a transcoded bitstream without performing error compensation for the skipped block.

    摘要: A communication method employed in a wireless communication system including a first communication device and a second communication device is provided. The communication method includes: setting up a connection between the first and second communication devices; after the connection is set up, checking if both the first and second communication devices provide a symbol mapping function for converting a first modulation/demodulation to a second modulation/demodulation different from the first modulation/demodulation; and when both the first and second communication devices provide the symbol mapping function, using the second modulation/demodulation to replace the first modulation/demodulation so that each of the first and second communication devices communicates with each other by using the second modulation/demodulation.

    摘要: An embodiment of an apparatus for channel assessment is provided, comprising a radio frequency (RF) unit, a baseband unit and a microprocessor control unit (MCU). The baseband unit coupling to the RF unit directs the RF unit to selectively hop into one of a plurality of available channels in a frequency band using a pseudorandom sequence to receive a plurality of packets via the hopped channel. The MCU coupling to the baseband unit accumulates a measure for the hopped channel according to reception results of the packets and marks the hopped channel as a bad channel when the accumulated measure exceeds a predetermined threshold. The measure represents the inaccuracy extent during packet reception via the hopped channel.
