Embodiment Construction

[0015] The following description uses a television device as an example, but the invention is equally applicable to desktop computer monitors or other types of stand-alone display devices.

[0016] Fig. 1 schematically shows a television device with a USB port in a configuration for firmware update in which the television acts as a USB host (also referred to as a USB master) according to an embodiment of the present invention. Figure 1 shows the control portion of a television device 10; other components of a television device (eg tuner, display screen, etc.) are well known in the art and are not shown here. The control section includes a processor 12, a PROM (or other suitable non-volatile memory) 14 for storing program instructions (firmware) and other data used by the processor, a USB port 16a, and an internal bus connecting the above components to each other 18 or other suitable communication channels. The USB port 16a is of the type used in devices acting as a USB host, ...

Abstract

A method and apparatus for conveniently updating firmware within a television device or a desktop computer monitor using a USB port is described. The TV or monitor is provided with a USB port. In a first configuration, the TV or monitor acts as a USB host, and updated firmware is transferred to the TV or monitor from a USB memory device inserted into the USB port of the TV or monitor. In a second configuration, the TV or monitor is connected to a PC via a USB cable and acts as a USB client. The updated firmware is transferred to the TV or monitor from the PC which acts as a USB host.

Description

technical field [0001] The present invention relates to a display device such as a television or a desktop computer monitor, and in particular to a method and apparatus for updating firmware in a display device. Background technique [0002] Television equipment includes one or more microprocessors and firmware stored in the television's internal non-volatile memory that controls many of the television's functions. Typically, when the firmware needs to be updated, a custom driver is used to load the new firmware into the memory via the RS232C port. The cables used for this task are typically mini DIN to DB9 cables. A typical user will most likely not own the cable or drive, so a firmware update will have to be done by a service person or at a service store. Additionally, the entire firmware is usually replaced. Computer monitors are similarly controlled by microprocessors and firmware, and similar problems arise when updating firmware in the monitor. [0003] Universal S...
