Samsung TVs get faster HDMI switching

15 Apr 10 01:14 by Jared Newman in category LCD TV

Can’t deal with the seconds of lag that occur when switching between HDMI signals on your television? Samsung’s got an answer.

Silicon Image announced that Samsung will be the first TV maker to use its InstaPort S technology, which cuts HDMI switching lag down to one second. Silicon Image claims that most other televisions take four to seven seconds to switch between HDMI devices.

HDTVs experience lag when switching between signals due to High-bandwidth Digital Content Protection, a form of copy protection for audio and visual connections including HDMI. InstaPort handles HDCP authentication in the background for all connected devices, so less time is needed for copy protection when you switch signals.

InstaPort S will be used in Samsung’s flagship line of 3D LCD and LED televisions (as long as you’re not too drunk to watch), though Silicon Image didn’t specify model names or numbers. Hopefully, the one-second switching of InstaPort S won’t be limited to 3D televisions.

Though the “S” model of port switchers is new, and faster than ever, InstaPort has been around and is used by other manufacturers including Sharp and Toshiba. In January, Silicon Image announced that it has shipped over 20 million InstaPort-enabled processors, featured in over 125 digital televisions. So while Samsung appears to have first crack at the latest technology, I suspect it won’t be long before other manufacturers follow.

Obviously, a fast transition from one HDMI port to the next isn’t the first thing you should consider when purchasing a television — unless you’re really impatient — but it’s something to watch out for if you plan to connect multiple game consoles and set-top boxes. Those four to seven seconds can add up if you’re scrolling down a long list of ports.

My TV takes a fraction of a second to pull up the list of connected devices (a few HDMI devices), and about 3 seconds to sync once you selct a HDMI device ... it doesn't wait 7 seconds per device while you're polling your HDMI ports. At any rate, my TV can assign either a predetermined, or a custom NAME to each input, so I don't need to poll each input to work out which device I'm watching.

If my TV took 7 seconds to sync, and I had to synch to every device to figure out which device was which every time I switched, I'd scream blue murder

Most TV's have 2, 3 or 4 HDMI inputs, and a few component/composite/other crappy non-digital signal inputs?

A good thing nonetheless.

A great thing would just to piss off HDCP altogether, but that's not going to happen anytime soon, is it?

And what happens if none of your connected devices will correctly support this faster handshaking?

Somehow, I expect that this "smart chip" engages the HDCP & handshaking when the TV is first turned on, and continues communicating at all times (I wonder how this effects your power bill??) so that switching appears practically seamless.

Just like electronic PC KVM switches, rather than ye-olde mechanical switches.

I'm surprised that TV manufacturers didn't think of this in the first place .....

Sigh, another example of DRM causing issues for the masses.

I, for one, am considering using a stopwatch to time how long I spend watching stupid anti-piracy ads on blurays/DVD's, and note how often I change to a HDMI device and have to wait.

At the end of the year, I should tally it up, and then charge it back to the MPAA for 2.5x my work consultant charge out rate. I think it's fair, I work 5 days, and get 2 days off .. makes my time 2.5x more precious than my work rate, due to the principle of supply and demand.

If everyone tallied up their wasted time, and sent a bill to the MPAA, then methinks the MPAA might change their tune in consideration of wasting everyones time.

The problem with today, is too much time wasting
Just call tech support for .. well .. anything ... especially when it's obviously a product fault .....
