  • Sound-effect setting method and electronic device
    Patent number: 9859859
    Abstract: A sound-effect setting method and an electronic device are provided. The sound-effect setting method comprises decoding an audio data stream; performing sound-effect processing on the decoded audio data stream according to a sound-effect parameter to obtain sound-effect processed audio data; encoding the sound-effect processed audio data to obtain encoded data and outputting the encoded data and the sound-effect parameter. When the audio playing is switched from the current apparatus to the external apparatus, the sound-effect coordination is achieved, and the problem that the playing effect will become poor if there is no sound-effect coordination is prevented.

  • Error detection method of variable-length coding code stream and decoding and error detection apparatus
    Patent number: 9608671
    Abstract: An error detection method of a variable-length coding (VLC) code stream includes at least the following steps: decoding a data frame of the VLC code stream; and determining whether the data frame is erroneous according to length information of the data frame and a bit number of decoded data of the data frame. According to the method, the present invention realizes the objective of performing error detection upon data frames during the decoding process.
