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.

This review is from: ANRAN 4 Channels H.264 Network Full D1 Motion Detection 4CH DVR CCTV Surveillance Security Camera System Digital Video Recorder (Electronics) Its not Plug and Play easy as stated by seller and also States it has world wide monitoring Capabilities and works with I-Phone and Droid and Cloud which is one feature I needed also stated by seller on description of product.The instructions are written for many models and not explicit enough on how to do anything, and it wasn't obvious and I failed trying to make it to work after hours of effort. not happy with product at all. it did auto format HD and link and display security cameras fine but this was by luck the instructions are poor, no glossary, no trouble shooting guides, no how too's. Just a description of all menus with no explanation of how or whys and what all the acronyms stand for. lots of acronyms, maybe a security person would know. I'm an IT major with computers but not security. and many translation misprints all throughout manual, obviously it was converted to English. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , December 26, 2014

This review is from: ANRAN 4 Channels H.264 Network Full D1 Motion Detection 4CH DVR CCTV Surveillance Security Camera System Digital Video Recorder (Electronics) I was looking for a device to make a 4-up display for a 16 channel security system. To buy a dedicated device to achieve this,I have purchased quite a few devices at over $100. Some of these devices were only for black and white, no color. Here, for far less than half the price, is a device that will hold a hard drive and offer me back up. I was so happy, I bought two. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , November 16, 2014

    Easy to set up to record

    After reading other reviews, I made sure that I put the HDD in before plugging in the DVR. After turning on the power the HDD formatted instantly. Within minutes it was up and running. I'm able to record based on motion detection which is what I wanted. For that purpose I give it 5 stars. I don't have it set up to view via internet so I can't comment on that aspect.As far as my technical ability, I simply went to youtube to learn how to put in the HDD. In other words, I'm not necessarily technologically savvy. If I can set this up to simply record, anybody can. If you're wanting info on how easy it is to set up via internet, again, I can't comment on that. I'm not set up via the internet.Oops, I need to make a change. I forgot that the remote doesn't work.

    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?)

    Good for the price

    Just received and installed. Cameras have narrow view, but work good in daylight. At night you will need to have a light near by to get any decent video. I Was able to connect my windows computers, tablets and phones through LAN. I am still not getting remote access, appears to be because I have an airport extreme. This product is not Mac friendly (can view using IE, but not safari). For My IPad, IPad 2, iPhone and Samsung galaxy s2 I used an app to get working on LAN. If you are installing your own hard drive it must be Sata, installation of hard drive was easy and directions were found in the owners manual. I will definitely be upgrading cameras over time to get wider views and audio. For the price I am satisfied. From what I can tell to get remote access you will need a DDNS name and server, which I am struggling to get working on my airport extreme.

    After reading several different reviews, I had a few questions regarding the device itself and decided to contact the company. I first tried the online chat and was given a rather lengthy SQL/PHP/Service unavailable message on the Live chat link from their home page. I next tried their phone support, where you give them your number and they call you. The estimated wait time was supposed to be 23 minutes, but 45 minutes later no phone call meant I'd try their company direct line...and got another 40 minutes of hold time. After spending close to 90 minutes to get in touch with the company that is supposed to be a global leader in surveillance, I figured an invalid link from their home page, a non-working phone support system, and the URLs they give you on their hold music going to pages that don't exist...I'm going to say I'm nervous about investing money in a global surveillance leader's product. when the web and phone support systems don't work.The bad: They are a... 1/5 Bryan Lemke (St. Johnsbury, Vermont) - See all my reviews This review is from: Zmodo PKD-DK4216 Surveillance Camera Kit with 4-Channel H.264 DVR and 4 Indoor/Outdoor IR Cameras - Hard Drive Not Included (Electronics) After reading several different reviews, I had a few questions regarding the device itself and decided to contact the company.
