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.

    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.I... 2/5 FlyBoy - See all my reviews Verified Purchase(What's this?)

    0 4/5 paul maksimovich - See all my reviews Verified Purchase(What's this?) This review is from: Night Owl Security L-DVR4 4-Channel 960H DVR with HDMI (Black) (Electronics) Good product for the money, easy to set up and get working to view from internet and mobile phones ( I know a few people who have had trouble because they don't mention this....don't forget to set up port forwarding on your router). Like previous people have said, the mouse and remote stop functioning after about a week....this is disappointing but you can access all of the configuration info from the software provided which is how I use it mainly anyways. Overall its a great cheap product that will work soundly except for the mouse/remote.Also I was aware of the mouse issue before using the product so I never left mine plugged into the dvr when not in use, still made it defect. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , August 28, 2014

    Not bad for the price

    If youre looking for hi tech crystal clear images and detailed images, move on. If you just want a basic, easy to install CCTV system this is great. Its as easy as mount the cameras with 3 screws, plug the cameras into the cables, run the wires to the unit and plug them in. Its easier than the average surround sound system.the night vision is OK, works well in darkness up to about 10 feet; the images are black & white though. The overall image quality is OK, if someone is within about 15 feet the image is clear enough to recognize a stranger by the photo. Past 30 feet you'd have a hard time distingushing between Jessica Simpson and Hillary Clinton. When you attempt to 'zoom' the image it gets very grainy, so forget that idea. The field of view is fairly narrow, so if you are using it in a small space (10x10 room) the view is limited.Overall, its a breeze to put in and use, just dont expect the best image quality. if youre a small business or a homeowner, its... 2/5 JS - See all my reviews Verified Purchase(What's this?)

    ZMODO DVR systems

    Do your research. I've seen a lot of bad reviews for Zmodo DVR's on other websites from people that don't know anything about CCTV IR based camera systems...I own 2 of these DVR systems, in my experience they are the best. For years I struggled with PCI based DVR solutions, (SAMS club specials to) they ALL SUCK. The software for all PCI based cards is the same Chinese garbage. No support, no updates, short operational life.Out of the box the Zmodo systems work very well and without hassle. Couple of points to this...#1 Camera quality, for the price you can't expect the best. The most important feature here is the DVR and these are worth the price (- cameras). These don't have much range, they are too small you really need to tailor cameras to your environment. Buy a larger one for distance visibility at night. Do your research. You can't expect these to see a license plate 15" away.#2 To improve image quality use coax and not... 5/5 Mech (Louisville, KY) - See all my reviews This review is from: Zmodo PKD-DK4216-500GB H.264 Internet & 3G Phone Accessible 4-Channel DVR with 4 Night Vision Cameras and 500 GB HD (Camera) Do your research.

    For the price paid.....THIS UNIT IS WORTH EVERY PENNY!!!

    This system packs a massive load of value for the price paid. If you're looking for a basic camera system with decent camera images, then this is what you're looking for. By no means is it a commercial level feature packed system that can produce "High Definition Images". It cannot see fine detail, but produces usable images to see mischef around your property or business. For example, if you want to know which neighbor is messing with your car or who's dog took a crap on your lawn, you can probably identify someone you've seen before. The closer you can get a subject to these cameras the more detail you can see.INITIAL IMPRESSIONS:The DVR looked exactly as I intended. It was a good size and included a Western Digital 500GB Green Drive with a very recent manufacturing date. The cameras were smaller than I thought. No problem with that. All metal construction. Looked perfect for my installation. Everything was packed well in China!!INSTALLATION:I had already... 5/5 JosephN - See all my reviews Verified Purchase(What's this?)
