An audio data recovery method, an audio data recovery device and a Bluetooth device are described. The audio data recovery method comprises: dividing audio data into a first frequency domain component and a second frequency domain component in a frequency domain; using a second data recovery algorithm to recover the audio data in the second frequency domain component; and using a first data recovery algorithm with lower complexity than the second data recovery algorithm to recover the audio data in the first frequency domain component.

An audio packet loss concealment method, an audio packet loss concealment device and a Bluetooth receiver are described. The audio packet loss concealment method comprises: determining whether each data packet divided into a plurality of frequency bins in a frequency domain is correct after audio data is transformed from a time domain to the frequency domain; classifying the frequency bins in the incorrect data packet into a first set of frequency bins and a second set of frequency bins; and recovering data in the first set of frequency bins by a GAPES algorithm, and recovering data in the second set of frequency bins by a predefined algorithm, wherein the predefined algorithm involves far less computation when compared with the GAPES algorithm.

Techniques pertaining to the transmission of digital data via a conventional transmission medium (e.g., a coaxial cable for TV) specifically for analog composite video signals are disclosed. To retrofit in an existing system not designed for transmitting digital signals or data, the techniques are provided to convert the data into an analog signal that is transmitted over a coaxial cable, where the analog signal, when received, is decomposed to recover the data. According to one aspect of the present invention, videos in high quality (e.g. high definition or HD format) from HD cameras are used in the conventional surveillance system, where the transmission medium for the analogy videos is already installed.
