Maybe this needs clarification: the PC I alluded to is the CPU only. It's audio goes over the stereo system, and its video goes on the 42" HDTV set. Keyboard and mouse are wireless remote. Once your favorites are set up, just about all you need for "channel surfing" is the remote mouse. It's beyond me why the CE vendors deliberately handicap their so-called "connected TVs."

Yunko, I think this is a pivotal point in your article: "Why bother streaming video content from PC, tablet or phone to the TV?" The reason is, it's more enjoyable to watch shows on the big screen, with good, hifi stereo sound. And you can get TV content from the web that is not available from broadcast methods, including terrestrial, cable, and satellite. For instance, if you want to watch shows independent of schedule, you can either record them on a PVR, or you can stream them from the web. Okay, in this case, you might have a point. But if you want to use Netflix or Hulu to watch online content, the web is your only source. Why should you be limited to doing so on a tiny screen with crappy sound? Or, if you want to watch news from all over the globe, these are not available over traditional TV broadcast methods, but easily available on the web. Again, why limit yourself to tiny screens and crappy sound? It's very easy to solve this debate. The CE vendors haven't figured it out yet, so they forced me to solve it on my own. A PC became part of my TV/stereo setup. It sits alongside the DVD player/PVR and the HD Radio tuner. I can hear radio and watch TV from any source, without limiting myself to doing so on a handheld gadget. And I got lazier, in that I don't need to program the PVR for time shift recording! I just can't buy the notion that the future only consists of trendy, short-lived, tiny hand held gadgets. These are new products, not necessarily replacing anything else.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
