Abstract: A method for processing an audio/video bit-stream includes the steps of receiving an input bit-stream, detecting whether the input bit-stream has a startcode emulation prevention pattern, and removing the startcode emulation prevention pattern from the input bit-stream to generate an output bit-stream and setting a flag signal as a first designated flag value when the startcode emulation prevention pattern is detected. The method further includes the step of detecting whether the input bit-stream includes a startcode, and directly outputting the input bit-stream and setting the flag signal as a second designated flag value when the startcode is detected.

Abstract: An operating method for an integrated interface of a PDA and a wireless communication system includes the following steps. Firstly, when the wireless communication system starts to operate from a standby mode, a state signal is transmitted from the wireless communication system to the PDA. Then, if the PDA receives the state signal when the PDA is in a sleep state, the PDA is wakened and an input source of an audio element inside the PDA is switched to the wireless communication system. An electromagnetic wave signal is received by a wireless communication element and converted into audio data. Afterwards, the audio data is transmitted from the wireless communication system to the PDA and outputted by the audio element.
