ECM/ECCM systems for aircraft have been pretty sophisticated for some time, though that system described in your video is a significant upgrade over the old chaff/flare/Jammer buckets we used along with the ALR and ALQ systems.
This is a chaff bucket:

Each of those round holes holds either a flare, a jammer, or a collection of chaff(kinda strips of aluminum foil that ****s with radar). They are loaded in a very careful order, and the pilot can fire off individuals, groups, rows, all of a type or just all of them. They perform basically the same job that the system in your video did, just a little lower tech. They work in conjunction with two very sophisticated electronics systems in the plane known as ALR and ALQ(which are pretty classified in what they do, and my knowledge is way, way out of date). Towable jammers where around when I was in, but where used for livefire exercises, not as combat ECM.
