Abstract: An image processing apparatus, and a method for controlling the image processing apparatus are disclosed. The image processing apparatus includes a data reader comprising data reading circuitry configured to read original data recorded on a storage medium, a signal processor configured to extract an audio stream and a video stream from the original data and to convert a format of the extracted audio stream and a format of the extracted video stream into a predetermined format, a communication module comprising communication circuitry configured to communicate with an external server, and a controller configured to control, when the data reader detects a read error or when the signal processor detects a demuxing error or a conversion error, the communication module to request the external server for at least one of: format-converted audio data and format-converted video data corresponding to a section in which the read error, the demuxing error, or the conversion error is detected.
