The B-Band Converter (BBC) module, installed on your HR20/HR21 or H20/H21 receiver, allows you to view the upcoming HD channels. Because DIRECTV's current HD channels do not require the BBC, it may not have been installed.

Please note: The BBC module works only with the H20/H21 and HR20/HR21 receivers. The information here applies only to DIRECTV customers with one of these receivers. If you live in an apartment or condo in a building where multiple units share one dish.The easiest way to tell if your H20/H21 or HR20/HR21 receiver has the BBC connected to it is to look at the back of the receiver. Look for a module that looks like the one pictured to the right. You can also check for the BBC module by tuning in to the Weather Channel, channel 362:
