Abstract
Methods and device for in-system firmware update in an information output device are provided. In one aspect, a method of firmware update in a display device receives a set of data in an image format through a video signal input channel of an input port of the display device. The set of data is converted from the image format to an instruction set format that is different from the image format. A first set of instructions that is used to operate the display device is updated with the set of data in the instruction set format.
Claims20
A method of firmware update in a display device, the method comprising:
- receiving a set of data in an image format through a video signal input channel of an input port of the display device;
- converting the set of data from the image format to an instruction set format that is different from the image format;
- and
- updating a first set of instructions that is used to operate the display device with the set of data in the instruction set format.
A method of firmware update in an information output device, the method comprising:
- receiving a set of data in a first format through a video signal input channel of an input port of the information output device;
- converting the set of data from the first format to a second format that is different from the first format;
- and
- updating a first set of instructions that is used to operate the information output device with the set of data in the second format.
A method of providing firmware for firmware update in a display device, comprising:
- generating a first set of instructions in a first format that is machine-executable to operate the display device;
- converting the first set of instructions from the first format to an image format;
- and
- transferring the first set of instructions in the image format into the display device through a video signal input channel of an input port of the display device.
A control circuit in an information output device, comprising:
- a memory configured to store a first set of instructions, in a first format that is machine executable, based on which the information output device is operated;
- and
- firmware update logic configured to convert a set of data received through a video signal input channel of an input port of the information output device from a second format to the first format, the second format being different from the first format, the firmware update logic further configured to update the first set of instructions with the set of data in the first format.
