A system and method of accessing digital video broadcasts within an information handling system is disclosed. In one form, a digital video broadcast processing system can include a digital video broadcast receiver module operable to process a first digital video broadcast data received within a multiple channel digital video broadcast signal and to output the first digital video broadcast data to an interconnect bus of a computer system. The digital video broadcast processing system can also include a communication interface operable to be removeably coupled to an interconnect bus interface of the computer system. The communication interface can be operable to communicate the first digital video broadcast data, including an interconnect dependent data format, from the digital video broadcast receiver module to a digital video processing application of the computer system.

An information handling system projector tracks lamp usage to generate a lamp order form for order of a replacement lamp when lamp usage is a predetermined usage. The lamp order form is automatically generated and displayed to include lamp usage and projector identification information so that a user need not manually input that information into an order form. A network module of the projector supports queries for lamp usage from a lamp management module running on an information handling system. A projector processor interfaced with the network module reads the lamp usage and projector identification information from firmware of the projector and provides the lamp usage and projector identification information to the lamp management module for automatic generation of the lamp order form display.

An information handling system projector lamp door includes a thermal safety latch that secures the lamp cover panel if the temperature of the projector interior exceeds a safety limit associated with potential harm to an end user. A thermostatic spring expands at a predetermined temperature to interfere with movement of a latch so that the latch is locked to secure the cover panel in a closed position. Below the predetermined temperature, the thermostatic spring retracts to allow movement of the latch so that the cover panel is released to move to an open position. An override interfaces with the thermal safety latch to allow manual release of the cover panel by retracting the thermostatic spring.

An information handling system projector lamp housing includes a safety interlock to reduce the risk of electrical shock to an end user during lamp insertion and removal. A ballast disposed in the projector interfaces with a low voltage power supply through a ballast power supply circuit and transforms the low voltage into high voltage for use by the lamp. A connector associated with the ballast connects with a connector on the lamp housing to supply the high voltage to the lamp. The safety interlock breaks the ballast power supply circuit if the ballast connectors are exposed, such as during insertion or removal of the lamp. The safety interlock completes the ballast power supply circuit as the lamp housing fully inserts in the projector to allow power supply for illumination of the lamp.

An information handling system projector cooling fan runs for a variably defined time after its lamp is turned off in order to adequately cool the projector without running the cooling fan for an excessive cool down period. In one embodiment, the cooling fan runs after lamp shut down until one or more thermocouples detects a predetermined temperature associated with the projector. In an alternative embodiment, fan cool down time varies based on the length of time the lamp was on before shutdown. The cool down thermal gradient is selectable between a convenience mode, in which an increased cooling gradient allows quicker cooling fan shut down, and a long-life mode, in which a decreased cooling gradient preserves lamp life.

Projection device failure may be diagnosed by sensing improper operation of projection lamp ignitor circuitry. An ignitor failure indicator may be activated based on a sensed failure in the operation of the lamp ignitor circuitry to prevent incorrect projection lamp failure notification.

Methods and systems for diagnosing projection device failure

Projector bulb life is managed to achieve desired performance parameters, such as a maximum life mode or maximum brightness mode, by sensing bulb luminance and applied the sensed luminance with a luminance feedback controller to drive the bulb to achieve the desired performance parameter. For instance, in maximum life mode the luminance feedback controller reduces power applied to the bulb to restrict bulb luminance to a maximum luminance setpoint when greater luminance is available with a newer bulb. In maximum brightness mode, the luminance feedback controller increases power applied to the bulb to increase bulb luminance if the sensor senses luminance below a threshold due bulb wear. Bulb life management improves project image illumination to display information in a variety of projector types, including digital mirror devices and liquid crystal displays.
