Rambus XDR memory architecture to empower next generation HDTVs from Toshiba

Memory bandwidth is one thing that many of our beloved electronic devices can use more of. More memory bandwidth means better performance from our gaming consoles, our computers and now our HDTVs.

In a joint announcement yesterday Toshiba proclaimed it licensed Rambus’ XDRTM memory controller interface cell (XIO) and XDR memory controller (XMC) for its forthcoming next generation HDTV sets.

The Rambus technology allows the delivery of the highest memory bandwidth available while using less DRAM devices. Toshiba will utilize the Rambus technology for its next generation HDTV sets that will deliver refresh rates of 120Hz, 12-bit color depths, multiple full HD Picture-in-Picture data streams and advanced image stabilization algorithms.

Rambus' XDR memory is often used in DLP projectors.  Electromagnetic fields around the DLP processor typically require unusual keep-out zones, resulting in long traces.  Rambus' Flex IO technology is one of the few buses that can compensate.

Deputy General Manager of Toshiba’s System LSI division Hideki Moriyama said, “HDTVs now require as much memory bandwidth as many PCs in order to deliver the advanced features consumers demand. With the XDR memory architecture, we are able to achieve both superior performance and a reduced bill of materials for our customers’ HDTV applications.”

In June of 2007 Rambus announced that over 25 million XDR DRAM devices had shipped, including the Sony PS3.

Don't get your hopes up for an XDR pairing with OLED televisions.  The company quietly announced over the weekend that it will not pursue large-scale OLED displays, despite previous promises of an affordable display by 2010.

Faster processing?

I wonder if this will get rid of the input lag when playing video games. I have a Sony 52XBR4 that is 120hz, but when you push a button on any game controller, it still takes quarter of a second to see the results on the screen. I still don't understand why that happens on my LCD TV but not on my LCD computer monitor. On some games that quarter of a second makes a huge difference.

You might want to make sure you have all of your display settings on what they need to be. Motion enhancement and all of that crap needs to be turned off on the new Sony XBR series. It makes things worse and seemingly "laggy".

Yeah, I turned Game Mode on (which automatically turns the Motion Enhancement off), and it actually did improve the timing by about 20% (best guess), but it's still noticeable compared to my CRT. And like one of the posts below, I am playing Halo 3, and that split second difference really gets frustrating sometimes. ...especially with snipers and shotguns.

If your console is hooked up to an HDMI cable...the decryption process is what is causing your 'lag'. Games like Guitar Hero realize this and provide a timing and synchronization method to at least sync with the picture you are seeing. I have a 360 with HDMI, and playing time-centric games like Halo3, where a split second can make all the difference pushed me off the HDMI cable and back to hd components. It looks absolutely identical, and I don't suffer a lag handicap.

Actually yes, I am using HDMI. I figured since I have the TV, why not go with the best cables? So, would a more expensive (higher transfer rate) HDMI cable improve things? I can just go back to component, but damn, HDMI was one of the reasons I got the Elite instead. :/ And I AM playing Halo 3. Sometimes that button lag makes the difference between kill or be killed. I didn't know there WAS a decryption process with HDMI either. I just thought digital was digital. Guess I'll see what component looks like. Thanks.

Use YPbPr then. It will be more faster than using HDMI. Otherwise u can use an old tv which dont have DHCP support. The encryption and decryption time in dhcp is causing u the delay.


120hz?

How exactly are these 120hz tvs going to be of any use when the input devices are all 60hz? Are they expecting the evolution of input devices to follow the introduction of this technology in tvs? Much like HDTV in 1998?

There are already 120 Hz TVs out there at the high end. Some of them include some special processing that allows for some "smoothing" effects. People seem to be split over whether they like this or not.

One of the big things for 120Hz sets is 1080p/24 playback from higher end HD DVD & Blu-Ray players. Since movies are shot at 24 fps, some people prefer that their television can actually play 24 fps without any 3:2 inverse telecine tricks. It's my understanding that 60 Hz TVs have to insert an extra frame here and there in order to deal with content at that framerate (since 60 is not a multiple of 24). Though I have not done comparisons myself, some people say that this results in a "less smooth" playback. With 120 Hz TVs, 24 fps is easily done because 24x5 = 120. Thus, it can play back 24 fps material in its native mode. I guess there are also a few TVs out there that can switch from 60 Hz to 72 Hz (24x3) to achieve similar ends with movies.


Huh?

What are the advanced image stabilization algorithms for?
