IR Blaster

The IR Blaster function allows the relay of Infrared (IR) commands through the WHDI link from the display unit (VDU) back to the source unit (VSU). This functionality is critical for maintaining the ease of use and transparent user's experience after upgrading the system to become fully wireless.
Since the TV should no longer "sit next to the STB," the user may choose to "hide" the STB in the closet for a neat-looking living room. However, the method to control the STB (switch channels etc.) is still done by using its original IR remote control. In order to keep the original IR functionality, the user will use the STB remote control and point it to the WHDI VDU (or to the WHDI enabled TV) which has an IR sensor. The VDU will receive the IR commanding signals and transfer it over the uplink to the VSU. The VSU, which resides in close proximity to the STB (same closet), will then re-transmit the IR signals ("Blast") using an IR transmitting LED so that the STB will be able to receive the exact same IR control signals it supports.
