Dave Zatz posted a video this morning from TiVo that discusses ATSC 3.0 and the potential of an external add on tuner that would be required. Help me understand this: I assume, this is OTA only? I assume this is a new broadcast standard that the onboard tuners cannot support? I assume the external device they are suggesting would replace / bypass existing onboard tuners? I assume the broadcasters would be required to send dual signals similar to the digital conversion? I am not sure what the benefit to the consumer is to actively get external hardware to utilize ATSC 3.0 instead of using the legacy broadcast. Am I understanding this or am I all over the place?
