External-device control apparatus and system
View Patent ↗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.
1. A system comprising:
a decoding apparatus;
an external device connected to the decoding apparatus in a way complying with local wireless communication standards;
first means provided in the decoding apparatus for extracting a prescribed descriptor from program specific information in a transport stream;
second means for sending the prescribed descriptor extracted by the first means to the external device;
third means provided in the external device for analyzing information represented by the prescribed descriptor sent by the second means to obtain an analyzation result;
fourth means provided in the external device for storing an arbitrarily designated operation control parameter which relates to operation of a controllable portion in the external device;
fifth means provided in the external device for generating a signal for control of the operation of the controllable portion in the external device in response to the analyzation result obtained by the third means and the arbitrarily designated operation control parameter stored in the fourth means; and
sixth means provided in the external device for controlling the operation of the controllable portion in the external device in response to the signal generated by the fifth means.
2. A system as recited in claim 1 , wherein the second means comprises means for detecting whether or not connection between the decoding apparatus and the external device is established, means for notifying a user of a connection failure when the connection between the decoding apparatus and the external device is not established, and means for sending the prescribed descriptor to the external device when the connection between the decoding apparatus and the external device is established, and wherein the external device includes means for sending a setting completion notice to the decoding apparatus when the sixth means completes the control of the operation of the controllable portion in the external device.
3. A system as recited in claim 1 , wherein the external device includes means for analyzing a descriptor corresponding to a change through manual operation after the sixth means completes the control of the operation of the controllable portion in the external device, and generating an operation log in accordance with the analyzed descriptor, and means for updating the arbitrarily designated operation control parameter stored in the fourth means in accordance with the generated operation log.
