Eagles fans, we can't guarantee you'll return to the top of the NFC East this season, but we can say you'll enjoy an Eagles Television Network lineup produced entirely in HD. Owner Jeffrey Lurie's film production experience (and we're sure an overpriced stadium beer or two) is apparently to thank for the transition, facilitated by some forward thinking during a recent master control upgrade, and new cameras from Panasonic. Unfortunately, the monitors in the stadium will still be standard def only, with no chance of an upgrade before 2009 at the earliest, but with Philly's history, odds are we can expect them before another sports championship in the city (though the Flyers may have something to say about that).

For those that witnessed the Nationals topple the Braves on Opening Day (at least on US soil), you got a glimpse of just how nice the all new Nationals Park really is. Now, Sanjay Talwani has taken an in-depth look at the stadium, and he found that copious quantities of HD equipment abounds. For starters, you'll find four 52-inch Sony LCD monitors along with a number of Luma LCDs within the control room, not to mention the 1,552 x 720 Mitsubishi scoreboard screen and the Sony MVS-8000G switcher. As for cameras, there are a pair of HDC-1400s alongside two wireless XDCAMs, but those pale in comparison to the four remote-controlled BRC-H700s around the top of the venue. 'Tis a shame the club's regional carrier, MASN, isn't diving in head first to carry all of its unclaimed matchups in HD, huh?

It's been far too long since we heard about the Dallas Cowboys' new stadium w/ accompanying gigantic four-sided HD scoreboard (and far too long before the 2009 season when it opens). Mitsubishi apparently thinks its the one to drop in new details, since it's their Diamond Vision technology (also soon to be seen at the new Yankee Stadium) powering the worlds largest 1080p LED displays, and we're in no position to argue. What can we say, exact specs on HD screens totaling nearly 13,000 sq ft make us weak. Check after the break for the full details before they're scheduled to turn on June 1, 2009.

Daktronics is continuing its quest to slather all available areas in your local MLB stadium with an HD screen of some type, with the latest target Citi Field, home of the New York Mets. Apparently eschewing the bigger/biggest race for a moment, no word on the size of a specific Godzillatron display, but Mets fans can expect 12,000 total square footage of display technology when installation is completed by August, ahead of the stadium's inaugural 2009 season. The main displays feature Daktronics' HD-X technology and will ensure that the best place to watch the game on TV is at the park itself. In other news about 'dat 'tronics, Bloomberg profiles the company's work on the Cowboys' enormous screen, and more than 18,000 sq ft of displays going into the new Giants-Jets stadium.

Update: The Mets also just acquired Johan Santana, so Mets fans can rest assured the next time their team is busy blowing the pennant race, they'll be doing it in a top quality ballpark with one of the game's best pitchers on the mound.

Boy, all these new high-def scoreboards is a trend we can really dig. Next up on the construction list is Camden Yards with their $9 million AV upgrades including a new sound system, control room, upgrades on the ribbon scoreboards and of course, the 16x9 HD screen. The ribbon cutting is expected in time for the '08 Oriole's season and reportedly, right before the 15-year-old Sony JumboTron (pictured) losses its last leg -- and last replacement part. Right now, it seems stadiums aren't concerned about sheer size anymore -- by our records, a Tokyo racetrack still holds the size title at 221-feet diagonal -- but keeping up with the Joneses and simply have a high-def scoreboard to call their own.

Although instant replay has its fair share of supporters and critics, it's here to stay in the NFL, and if you're hoping that the grainy SD playback that refs have to review might lead to a beneficial miscue, don't count on it. The NFL has teamed with Harris Corporation to install 33 NEXIO HD servers (plus 33 more for redundancy), an HD version of FORCE (Football Officiating Replay Challenge Expeditor) software, and routing / distribution gear that will enable officials to look back at questionable plays in "stunning high-definition." Every NFL stadium but three -- the ones "being replaced" in Irving, TX, Indianapolis, IN, and East Rutherford, NJ -- will be equipped with high-definition equipment and recabled "before the upcoming season." As expected, such (potentially superfluous) upgrades won't come without selling quite a few grossly overpriced sodas and soft pretzels, as it's estimated to cost each club around $300,000.
