Abstract
The invention provides a task scheduling method which can prevent overflowing of a buffer on a host system or a data encoding/decoding apparatus even when the transfer rate falls in case the compressed data and the non-compressed data are simultaneously transferred between the host system and the data encoding/decoding apparatus. In a task scheduling method, the compressed audio/video data is transferred from the buffer of the host system to an external device with a first transfer priority. The non-compressed audio/video data is transferred from the buffer to the external device with a second transfer priority lower than the first transfer priority.
