Pace Micro has announced the launch of the world's first DVB-H H.264 mobile personal video recorder (PVR) - the PDH400.
The Pace PDH400 integrates the new DVB-H standard into its existing mobile PVR device - the PVR2GO - enabling live digital content to be watched and enjoyed by the subscriber on the move - wherever they are, whenever they want.
With a 4.3" color widescreen display, the PDH400 also works as a shared experience for viewers. DVB-H trials are now underway in Finland (Helsinki), Germany (Berlin), United Kingdom (Oxford) and United States (Pittsburg).
As well as enabling live TV content on the move, PDH400 also works as a personal video recorder (PVR) and comes with a maximum hard drive capacity of 40Gb, which can store in excess of 200 hours of programming. Streaming H.264 from a solid state memory SD-card is also supported.
Pace has been working with Sony and Broadcom on the electronics.
Broadcom's mobile H.264 chip solution, the BCM2702, offers high-performance decoding for H.264, WMV9 and a whole range of audio and video codecs. Combining programmability with best-in-class power consumption, it is the ideal choice for DVB-H, T-DMB or any other mobile TV standard". Pace is also working with NDS to integrate NDS mVideoGuard DVB-H CA and an ESG (electronic service guide) into the PDH400.
Recently, DiBcom SA, a small French startup, announced they will partner with Intel to add mobile TV to Intel's Centrino and Xscale platforms. DiBcom's digital TV chips are capable of 24-Mbit/second reception at 150 miles per hour. DiBcom's DVB-H (digital video broadcast-handheld) competitors include TI's Hollywood Chip, Freescale, Philips, Samsung and STMicroelectronics. Crown Castle Mobile Media in Pittsburgh, operates an ongoing DVB-H trial using the 1.672-GHz L-band.
DaVinci is TI's next-generation digital video engine, expected to be inside IP set-tops, digital TV, video telephony, digital still cameras and portable video. The DaVinci processors consist of DSP-based system-on-chip, integrating DSP and ARM cores, accelerators, peripherals and necessary software, the Dallas-based company said.
For mobile phones designed to handle planned broadcast TV service in the U.S., Samsung's tuner operates in the L-Band (1,670-1,675 MHz). For those targeted at Europe, it also will function within the European UHF frequency range (470-890 MHz) and the L-Band spectrum likely to be allocated for European mobile TV broadcast (1,452-1,477 MHz).
Castle Mobile Media will use the mobilized television standard, DVB-H on their 1.7 GHz band next year.
Other backers of DVB-H include Microtune, Nokia, O2, S-Communications, S3, Texas Instruments, TTPCom, and UDcast.
A DVB-H radio receiver in the handset sends 15 Mbit/s of data per 8MHz channel, and adds error correction to compensate for poor reception. U.S. television channels are limited to 6 Mbps, producing around 12 Mbit/s. The robustness of COFDM in mobile environments makes it a good match for mobile multi-media devices, receiving broadband TV and data off the air. DVB is a global television standard and uses COFDM instead of the multipath prone 8-VSB-based ATSC standard.
Pace also demonstrated the world's first DVB-S2 H.264 high definition (HD) set-top boxes for commercial deployment. The DVB-S2 standard is an MPEG-4 follow-on to the MPEG-2-based Digital Video Broadcast standard now used for DBS satellite television. It features 30% better compression efficiency.
Many new products are being demonstrated at the big International Broadcast Conference, this week in Amsterdam.

unmediated.av:
The Weekly Show
drawing from extrastruggle.
We've been having a back channel conversation amongst the trackers at unmediated about how/whether to update the way in which we aggregate, present, and make useable the content on the site, in light of all the various aggregators, digg and its clones, and role model group blog sites that we all consume/use/hate/love. Since we all primarily support open media movements and the freedom of bits and so forth, and with all of us being busy with our primary projects, we are looking for ways to make getting content on the site easier and more streamlined, while making it obvious that we are presenting other sources content. With the availability of open API's for just about any type of media aggegration literally getting past the saturation point, and mashups taking every possible form, we are wondering, is it time to take a step back, or a step forward with how/what we do at umediated? In the course of my surfing today, i found this new site, Boxxet Which just might be the straw that breaks the camel's back in how we all perceive the current mix and match nature of the web as it now stands. What's different about Boxxet from other aggregators and mashups like the newest entry popurls, (which aggregates digg, slashdot, reddit, newsvine, tailrank, and flickr) is that Boxxet is a Website generator. Thats right, just pop in all the urls u want to aggregate (and WHAT from them) choose how u want to format it, plug in the url that u want it to be accessed at... and whammo: Your own site with everyone elses content, and all thats left to do is decide whether googleplex or yahooza is going to be the source of your linklove revenue. And if u have on older domain that u plug this into...well, we all know how the pageranking with search engines work by now. It used to be that u had to have a bit of code knowledge to make all this stuff work. Eyebeam's Re-blog engine which powers this site was not a simple undertaking at the time that Michael Frumin and Michael Migurski put it all together... a half a year before Marc Broadband-mechanicked the term Reblog as his latest buzzword before casting his attention on the ourmedia-meme. (kudo's, kudo's) But now, with the cut and paste mentality of webculture that we at unmediated have helped create, the pace at which people are remixing and repurposing code is accelerating at a rate similar to the curve that we saw with pro-sumer desktop video... almost anyone can do it. I have this sinking feeling in my gut that we will arrive sooner than later at the same existential threshold that the film studios and record labels are squirming under to our joyful cries of "die, dinosaurs, die!". What i am wondering, is how long until my hero of the open-information movement, Cory Doctorow, and the rest of our pals at BB will tolerate re-aggregation and repurposing of his content, (now that he is investing so much more time at the site) before he (or any of one us) screams, "FOUL!" Stewart Butterfield over at Flickr is dealing with this beast at the moment...and i have to admire the dryness with which he states, "I loaded the FlickrCentral pool and firefox got up to using 240mb of ram before dying. So that's not a great user experience, but it's really terrible for Flickr. If it catches on and you don't limit it, we'll have to cut you off :\" Sure, Stewart, blame it on the user experience and firefox. ;) I admire your candor, and personal attention/approach to what has become one of the hottest new BRANDS in Web 2.0 ...that u still have time to be personal and all flickr-fuzzy even after being acquired, but I am sure that your jeans feel like they're fitting a bit tighter all of a sudden. Pretty soon, I expect, a lot of us bell-bottomed infornistas are going to wake up in a similar pair of Jordaches. I'm curious which of us will cut the inseams and sew in another totally different material to keep our style,and which of us will claim that now that we're wearing skintight jeans ("they're really really comfortable...REALLY! You think i should get a pair of Reeboks to go with 'em?"), that the manufacture of bell-bottoms should be forbidden. I point this all out in good humour only to illustrate a point: The times, they are('nt) a changin'>, and Cory just might wake up one day soon in his magic kingdom, and say "Hey, man, where'd all my whuffie go? And he's going to have no choice but to join Walt's pinstripesuits in pushing for copyright extension. It's a pill i hope he (and we) never have to swallow. So i pose the question to our community readers: How do you see unmediated-Are we crossing the boundaries in how we repurpose content? Would you like to see more editorializing? Narrower/Broader scope? Are we a repository of information that you come back to use, or just part of your daily information addiction? Let us know... I, for one, would like to have an idea about what pair of jeans to wear this year ;) michael
