Abstract
An Audiovisual equipment comprises a data input interface, an analog-to-digital (AD) converter, a retrieving circuit and a processing unit burnt with program codes is provided. The data input interface receives analog data from a data source carrying updating data therein. The A/D converter converts the analog data into digital data which is then transmitted to the retrieving circuit. The retrieving circuit retrieves updating data and then transfers it to the processing unit. The processing unit updates the program codes using the updating data.
Claims33
A circuit for updating an audiovisual equipment, comprising:
- a data input interface for receiving analog data from a data source, wherein the analog data carries a updating data;
- an analog-to-digital converter for converting the analog data into a digital data;
- and
- a retrieving circuit coupled to the analog-to-digital converter for retrieving the updating data from an output of the analogue-to-digital converter and using the updating data to update firmware of the audiovisual equipment.
An audiovisual equipment, comprising:
- a processing unit having program codes:
- a data input interface for receiving analog data from a data source, wherein the analogue data also carries updating data;
- an analog-to-digital converter for converting the analog data into digital data;
- and
- a retrieving circuit coupled to the analog-to-digital converter for retrieving the updating data from an output of the analog-to-digital converter and transmitting the updating data to the processing unit for updating the program codes inside the processing unit.
A method for updating firmware of an audiovisual equipment, comprising the steps of:
- loading updating data into analog data;
- transmitting the analog data to the audiovisual equipment;
- retrieving the updating data from the analog data;
- and
- utilizing the updating data to update the firmware of the audiovisual equipment.
An audiovisual equipment, comprising:
- a data input interface, receiving and outputting a multi-medium signal carrying a updating data;
- and
- a retrieving circuit, receiving the multi-medium signal from the data input interface, retrieving the updating data from the multi-medium signal so as to update a device connectable to the retrieving circuit.
A method for displaying an audiovisual equipment, comprising:
- loading an updating data into a multi-medium signal;
- receiving the multi-medium signal carrying the updating data;
- retrieving the updating data from the multi-medium signal;
- and
- updating data built in a device by using the updating data retrieved from the multi-medium signal.
