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.

    0 5/5 DallasClubGuy "DCG" (Texas) - See all my reviews Verified Purchase(What's this?) 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

    0 3/5 JK (Iowa, USA) - See all my reviews Verified Purchase(What's this?) 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) It works. The user interface is clunky, but every security DVR I've used is. For the price I paid it's acceptable. I have not yet tried to stream the video over the public internet, but I am able to view it from my laptop on the LAN.Installation was pretty easy. I stuck a random hard drive that was laying around into the unit, connected it to my TV, and powered it up. It formatted the drive and I went through the config menus. After that I moved it to a corner of the basement and put it to work. I haven't touched the unit since. If I want to look at it, I use the included software. Speaking of which, that software sucks. Again, every DVR I've used is pretty bad, even some that cost a lot more than this one. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , January 14, 2015

    Cheap but impressive.

    For the price, I would have given it 5 stars but,,, the remote was DOA ( that means "dead on arrival") and the led indicators for "Alarm" and "Record" are reversed. (I'm sure that's just a hardware programming error but my soldering iron can fix that, hehehe). The instructions are in broken English and leave out some important steps, like how to hook up to a router and connect wirelessly to a laptop, Simple instructions as to how to match up the IP addresses, what matters and what will be done automatically.... I didn't knock off a star for that because the operating system/menu/program, whatever you want to call it, is simple enough, that after 4 nights of trial and error and slogging through the instructions, I have managed to set it up to record motion only in short videos and I can review saved files and watch real time wirelessly on my laptop. (I think the Author of the instructions assumed the users would understand networking and does not simplify or... 4/5 James - See all my reviews Verified Purchase(What's this?)

Sadly, it will be a while before I can test that information... but based on other aspects of my experience, I won't be surprized if that knowlege fixes my initial problems with motion detect. Having been lulled into a sense of false security by the good standard in many aspects of the interface, I failed to try making the number higher to get the device to ignore slight noise from my camera.
