ABSTRACT:
In an external-device control apparatus, a first section extracts a prescribed descriptor from program specific information in a transport stream. A second section analyzes information represented by the extracted prescribed descriptor to obtain an analyzation result. A third section stores information about setting of operation of an external device. A fourth section generates a signal for control of the operation of the external device in response to the obtained analyzation result according to the information stored in the third section. The fourth section sends the generated signal to the external device.
