Abstract

A testing apparatus, coupled to a mobile storage device, includes a control module and an intermediate module. The intermediate module, coupled to a television system and the mobile storage device, is for switching a subordinate status of the mobile storage device. The control module controls the intermediate module to write target data into the mobile storage device, and to allow the mobile storage device to output the target data to the television system.

Claims

1. A testing apparatus for a television system, coupled to a mobile storage device, the testing apparatus comprising:

an intermediate module, coupled to the television system and the mobile storage device, for switching a subordinate status of the mobile storage device;

a control module, coupled to the intermediate module, for controlling the intermediate module to write data into the mobile storage device and to allow the mobile storage device to output the data to the television system, wherein the control module writes data into the mobile storage by steps;

sending a first switch command to the intermediate module to set the mobile storage device to be subordinated to the control module;

receiving a first acknowledgement message from the intermediate module in confirming the first switch command;

sending a write command to the intermediate module to write data into the mobile storage device

receiving a write acknowledgement message; and

sending a second switch command to the intermediate module to set the mobile storage device to be subordinated to the television system; and

a confirming module, for confirming whether the data is correctly read from the mobile storage device and written into the television by receiving a predetermined response signal from the television system to the intermediate module when the television system correctly and automatically reads the data from the mobile storage device;

wherein, when the confirming module does not receive the predetermined response signal or the received predetermined response signal is incorrect, the confirming module determines that the data function of the television system automatically reading data from the mobile storage device has malfunctioned;

wherein, when the subordinate status indicates the mobile storage device is a subordinate to the control module, the control module writes the data from the control module to the mobile storage device via the intermediate module, while the television system is not directly coupled to and unaware of the presence of the mobile storage device; and

wherein, when the subordinate status indicates the mobile storage device is a subordinate to the television system, the television system automatically reads the data from the mobile storage device.

2. The testing apparatus according to claim 1, wherein the data is updated firmware.

3. A testing method for a television system, the television system coupled to a control module, an intermediate module, and a mobile storage device, the method comprising:

sending a first switch command from the control module to the intermediate module for setting the mobile storage device as being subordinate to the control module;

receiving a first acknowledgement from the intermediate module to the control module in confirming the first switch command;

writing data from the control module into the mobile storage device;

receiving writing acknowledgement by the control module;

sending a second switch command from the control module to the intermediate module for setting the mobile storage device as being subordinate to the television system to allow the television system to automatically read the data from the mobile storage device; and

confirming whether the data is correctly read from the mobile storage device and written into the television by receiving a predetermined response signal from the television system when the television system correctly and automatically reads the data from the mobile storage device;

wherein, when no predetermined response signal is received or the received predetermined response signal is incorrect, a determination is made that the function of automatic reading data from the mobile storage device has malfunctioned;

wherein, when the mobile storage device is a subordinate to the control module, the control module writes the data from the control module to the mobile storage device via the intermediate module, while the television system is not directly coupled to and unaware of the presence of the mobile storage device; and

wherein, when the mobile storage device is a subordinate to the television system, the television system automatically reads the data from the mobile storage device.

4. The testing method according to claim 3, wherein the data is updated firmware.
