About this book
The First to Present 3D Technology as Applied to Commercial Programming for the ConsumerThis is the first book to provide an overview of the technologies, standards, and infrastructure required to support the rollout of commercial real-time 3 Dimension Television/3 Dimension Video (3DTV/3DV) services. It reviews the required standards and technologies that have emerged—or are just emerging—in support of such new services, with a focus on encoding mechanisms formats and the buildout of the transport infrastructure.While there is a lot of academic interest in various intrinsic aspects of 3DTV, service providers and consumers ultimately tend to take a system-level view. 3DTV stakeholders need to consider the overall architectural system-level view of what it will take to deploy an infrastructure that is able to reliably and cost-effectively deliver a commercial-grade quality bundle of multiple 3DTV content channels to paying customers with high expectations. This text, therefore, takes such a system-level view, revealing how to actually deploy the technology.Presented in a self-contained, tutorial fashion, the book begins with a review of 3DTV in the marketplace and the opportunities and challenges therein. Recent industry events related to 3D are also discussed. From there, the fundamental visual concepts supporting stereographic perception of 3DTV/3DV are explained, as are encoding approaches. Readers will understand frame mastering and compression for conventional stereo video (CSV) and more advanced methods such as video plus depth (V+D), multi-view video plus depth (MV+D), and layered depth video (LDV).Next, the elements of an end-to-end 3DTV system are covered from a satellite delivery perspective, with explanations of digital video broadcasting (DVB) and DVB-handheld. Transmission technologies are assessed for terrestrial and IPTV-based architecture; IPv6 is reviewed in detail. Finally, the book presents 3DTV/3DV standardization and related activities, which are critical to any type of broad deployment.System planners, the broadcast TV industry, satellite operators, Internet service providers, terrestrial telecommunication carriers, content developers, design engineers, venture capitalists, and students and professors are among those stakeholders in these services, and who will rely on this volume to discover the latest 3D advances, market opportunities, and competing technologies.

    Inexpensive Camera System That Works Great@

    0 5/5 Jamie Ratliff - See all my reviews This review is from: Q-See QT534-4E4-5 4 Channel Full D1 Surveillance System with 4-700TVL Cameras and Pre-Installed 500GB Hard Drive (Electronics) Vine Customer Review of Free Product (What's this?) I have used multiple camera systems before, including top of the line consumer systems like Lorex, which can easily cost a thousand dollars more than the Q-See system here. The Q-See system is easy to setup, and includes a large poster like instruction sheet with step by step instructions for getting started. The directions are even in English! (I have seen some only in Chinese or something). I have used this camera system two ways. The first is a fixed mounted system that keeps an eye on our driveway and where the cars and trucks are parked. I have also used the system during a Paranormal investigation by taking with me and using a few of the Q-See cameras and a couple of older cameras from Lorex. I was happy with the system in both instances. The remote viewing option if great to have, and makes it easy to check up on things while you are gone. If you are looking for a camera system for your home or small business, this system is a good investment. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , January 10, 2014

    Doesn't Live Up to Claims

    Like the other reviewer said, we wanted to like this system. The main reason we are returning it is because the video is so bad that unless the subject gets within 20 feet or less from the camera (during daylight), it will be virtually impossible for Police to positively identify the perp. The picture is very grainy until they get at least that close. Night vision you lose even more definition but it wasn't as bad as we had expected. So if you need this for close up areas, you should be fine but if you want to mount this on the eve of your house, you probably aren't going to get video worth a darn. Their claims of 100 feet, yes you can see a body but it's a faceless body and even during daylight hours, you can't even positively identify the color of clothing the person is wearing until they get within 20 feet or so. The second reason we are returning is that it's not cooperating with our network so we can remotely view our cameras. We've followed all instructions, went online to try... 2/5 D.

    It could have been great...

    The specifications were good, and the price was less than I would have expected.I guess this is another example of "you get what you pay for."I opened the box and set everything up as documented, but the unit didn't power up to the configuration screen as it should have and the mouse and remote didn't work.Called customer support and, after 30 minutes of re-booting and other button pushes, it was determined that the unit was defective.Stuff happens, so I anxiously awaited a replacement unit without great concern.I unboxed and set up the replacement unit and it worked flawlessly... for about 90 minuted, before the remote and USB mouse stopped working.I tried all the tricks Customer Support had shared previously to no avail.Maybe I'm unlucky... Maybe they got a bad batch of serial controllers.... maybe it's just cheap junk.Regardless, back in the box and back to Amazon it went... 2/5 FlyBoy - See all my reviews Verified Purchase(What's this?)

    It's actually pretty awesome, once you get it all setup.

    I'll begin my review by saying, this unit is worth the money, affordable and does a great job with nice features, but it can be complicated to set up, so it'll require a little effort and patience, but well worth it!It does what you might expect, but the instructions can require a masters degree in technology to understand at times. The manual is also not current with the actual menu. Thank goodness I am tech savvy. I had some problems right out of the box, but it does work like expected.I tried online chat support several times only to get the message; "department closed". But support by email was very responsive and helpful. Although if you dig deep enough, you usually find the info you need in the Zmodo websites Knowledge Base.It's a nice looking unit, nice compact size, design and quality construction. The motion record is a cool feature. It has some great options. I couldn't find a firmware update online but support sent me a link. Some... 4/5 David L.

    great dvr at a low cost

    0 4/5 pl - See all my reviews Verified Purchase(What's this?) This review is from: Zmodo ZMD-DD-SBN4 4 CH D1-30FPS Real-time H.264 Security DVR - No Hard Drive (Electronics) The DVR is pretty good, does everything it states. However, unlike another Zmodo dvr i have, it requires you to open 4 ports on the firewall for connecting thru the internet (web, command, media streaming, mobile), and I have hard time finding a Windows Phone 8 mobile app to connect to the dvr. I have no problem using an app to connect to the other DVR, but not this one. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , March 11, 2013

    User-Friendly

    I bought this DVR to replace a POS Night Owl system that died.This is much more user-friendly, and seems to have more thought put into the menu design. It is apparent that some menu items were poorly translated to English, though.I have 2 downfalls to report, and both are definitely not deal-breakers for me:1. There is a physical power switch on the back. -You actually have an option to shut down (requires your passcode!), but must turn off power at the switch, and turn back on at the switch. The power button on front is only a software button, and will not bring the DVR back up once shut down.2. Video files downloaded via the Windows software are in a proprietary MP4 file. I have searched and searched, but found ZERO decoders that will play or convert these. You must resort to using the Zmodo player. -MP4 and AVI files downloaded directly from the DVR using a USB drive are playable with most software, and can be converted to other... 4/5 Andrew (Texas) - See all my reviews Verified Purchase(What's this?)
