<p>According to one embodiment, a signal processing device (1) includes an obtaining module (11), a measurement module (1011), and a first determination module (101). The obtaining module (11) is configured to obtain first broadcast data encrypted by a first encryption processing. The measurement module (1011) is configured to measure processing load during a recording processing on the first broadcast data. The first determination module (101) is configured to determine whether decryption is performed by a first decryption processing, for each region of the first broadcast data, on the basis of the processing load.</p> |
