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.

    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.

    i had some issues with it

    first two of the cameras did not work properly. I dealt with technical support. It took 1 hr for them to answer the phone and start asking me to read emails from them with procedures. they do not help you over the phone, just listen to your problem and send you a email with procedures. I actually bought two systems but ended up returning 2 bad cameras which took me about 10 days and a lot of emails and phone calls. But to return a item you can not speak with a live person. You have to leave a message in answer machine and they call you back. The second set came with the same problem and I didn't want to deal with their costumer service anymore. I just returned it.As far as the quality of the cameras, the ones that work are not so bad. you can actually see pretty good during the day and at night. and took me couple more days to figure it out how to access the cameras in remote control or from your cell phone. Again more emails with procedures, and was not easy to do by... 2/5 Junior Freire - See all my reviews Verified Purchase(What's this?)

    0 5/5 Mr. G Tech - See all my reviews Verified Purchase(What's this?) This review is from: Aposonic A-S0401R21SL Compact 4-Channel Full 960H/D1 Recording Surveillance Security Standalone DVR with HDMI Output, Mac Ready (Black) (Electronics) I usually don't take the time to review items I buy on amazon, but I felt I had to pass on some information regarding this aposonic drv. Its a great product. I have bought three other brands vonnic, SANNCE and this product blows them out of the water. The product is well designed and the software written running this little linux box is great. The support is great unlike the other brands. I have spent hours the other brands working the right way. This one took 10 mins out the box.When you shop for a DVR make sure to read other people's review. It will save you a headache and time. Its not worth saving $50 on a dvr and get a spotty system. Trust me I've been there and done that. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , October 30, 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?)

I was expecting grainy pictures and figured as long as they are "OK" then I will be happy. I am much very happy with the system and quality of everything. The system is very user friendly and easy to operate, getting the network up and running isn't difficult if you are computer savvy. Overall for less than $200 I have a great system that I can see anywhere, and its one more deterrent for thieves or vandals.I included pictures so you can see the quality, I have two of them run with 100ft wires with no quality loss and these pictures are on my 55" tv so you can really see how good this system is.
