A blood storage container suitable for quick and efficient production of a large amount of serum while ensuring high safety, and a method of separating blood and a regenerative medical process using the same are provided. The collection waveforms are represented as linear combination coefficients of an adaptive subset of the basis waveforms to compress an amount of stored information needed to reproduce the collection of waveforms. The addition of alternating positive and negative DC-offset values doesn’t affect the output load, and doesn’t degrade the signal. The scene category data includes data describing an environment in which the media volume is regulated. The method includes performing a booting process of the portable terminal at the occurrence of a booting event, examining whether a Universal Serial Bus port is enabled during the booting process, if the USB port is enabled, receiving data through the USB port before driver loading, and storing the received data into the large-capacity internal memory and performing the booting process.
