Cable TV (CATV) was originally added for remote communities that were out of reach for the ‘over the air’ analog TV stations. CATV first came out in 1948. It primarily carried the traditional network affiliate stations of the nearest city (ABC, CBS, NBC, and PBS). There really were not any other options for TV coverage, in these remote areas. Over time, additional channel selections were added, above and beyond these local affiliate channels, such as sports and movie channels. Cable providers also included local TV stations from other cities; WOR (New York), WGN (Chicago), and WTBS (Atlanta).
This bigger selection of TV channels made Cable popular, and became available in many major cities by the early 1980’s. In addition to the bigger selection of channels, it also eliminated the need to constantly adjust the ‘Rabbit Ears’ antenna for each channel. A few years later, Satellite TV became another similar option.
By the early 2000’s, we were seeing a lot of consolidation within the Cable Industry. Additional bells and whistles were added to the service, including On Demand and DVR. Now, with less competition and higher prices by the various Cable TV networks to re-transmit their services, prices for Cable and Satellite have been going up yearly and getting quite expensive. Some of these providers also charge extra, to receive the HDTV version of the channels.
While you can buy packages of services, there has typically not been an ‘ala cart’ option for channels. This is now changing with a new service of ‘Streaming Media’ of pay TV networks by companies, such as; Netflix, Hulu, and Amazon (just to name a few). They offer smaller numbers of ‘packaged channels’, for a lower rate. While it is cheaper than Cable or Satellite TV, the fewer channels that you get with Streaming Media, are actually more expensive on a per channel average. To use Streaming Media, you also need to make sure that you are using a high-speed network (15mbs or higher), particularly for HD content.
There has been substantial technology changes with ‘over the air’ (free) television in the past several years. The biggest of these has been the conversion from Analog to Digital. With Digital, a TV broadcaster can now create ‘digital sub-channels’, which is a method of transmitting more than one independent program stream simultaneously from the same TV Station on the same frequency channel. This is done by using ‘data compression’ techniques to reduce the size of each individual program stream, and multiplexing (also called multicasting) to combine them into a single signal. The broadcaster can send a single program at 19.39 Mbps. For example, using sub-channels, they can divide the channel into four streams of 4.85 Mbps, each. For example, if the digital TV channel is 14, then 14.2, 14.3, and 14.4 would be its three sub-channels. A key point is that different formats are supported for broadcast on the Digital channel, including; 480 (704 x 480 pixels), 720 (1280 x 720 pixels), and 1080 (1920 x 1080 pixels). The higher the resolution, the lesser number of sub-channels can be supported. While the primary channel program will typically be in high definition (1080 or 720), the sub-channels will typically use a lower definition. A good example of this, is the standard configuration for most of the ION-owned TV stations:
Having these sub-channels, gives you many more channel choices than with Analog TV. For example, when I run a channel scan (in Denver), I can typically pick up between 60 and 70 channels, with my indoor antenna. Of course, like with Cable or Satellite, you probably may not be interested in watching a number of the available channels, but you now have much more choices than you used to have with Analog over-the-air TV. For best reception, I would recommend using an antenna, which is Omni-Directional (without having to move it) and is amplified. I one respect, I still miss Analog TV, allowing you to at least somewhat pick up a distant station, even if it has a little ‘snow’ in the background. With digital, it is a case of ‘all or nothing’. If you cannot pull up the station clearly, you won’t get it at all. At times (if the atmosphere carries signals further), I can pick up a Cheyenne, Wyoming TV station (from Denver), which is 125 miles away. When I do, it comes in just as clear as a local station, but otherwise, if the signal is weak, I will not receive it at all. It may first appear as a checker-board pattern but then go blank. Interestingly, with Analog TV, the VHF channels seemed to have better reception than the UHF channels. With Digital TV, the UHF channels have the better reception. In fact, a couple of Denver’s TV stations which are on the VHF channels are simulcasting their broadcasts on UHF sub-channels.
Also adding to the growing number of ‘over the air’ channels is the addition of Low Power TV Channels. Cities are assigned a limited allocation of full power TV stations, to ensure there is no interference of TV signals between cities. With Low Power, additional channels can be assigned and cover a smaller metropolitan area footprint, so they can be assigned without worry of interference. Companies, such as ‘Syncom Media Group’, are purchasing these low power channels, and then lease out the sub-channels. This allows other companies/organizations to run a TV sub-channel at a much lower cost. The following diagrams give a good example of the coverage of a Low Power TV station versus the coverage of a Full Power TV station in the Denver TV market:
Low Power TV Station Coverage
High Power TV Station Coverage
Finally, going back to the original question — With the ever increasing prices of Cable and Satellite TV services, is ‘over the air’ (free) TV making a comeback? My opinion is that it is making a comeback. Again, the benefits are; it is free (including HDTV format), more channel program selections, and a clear picture without having to adjust the antenna for each TV station. While free TV may not have some of the cable channels that you like, I see additional streaming TV options becoming available to provide these specific sets of channels. This will prove to be a good cost savings over Cable/Satellite. Perhaps this will be a wake-up for the Cable/Satellite companies to change their pricing models.
Today, Electronic Messaging is an embedded part of our Daily Lives, whether as e- mail, Instant Messaging, Skype, Facebook, just to name a few. We really don’t concern ourselves on how to configure or doing message testing – we just know it works!
That has not always been the case. Over the years, a lot of planning and development was required to bring about the messaging systems of today. This also included the creation of ‘standards’ among the various vendors creating messaging software. “Standards”, are industry agreements and rules on how to design and create the software to smoothly work in a multi-vendor environment. For instance, you might think of the “Internet” as a standard, it might be better thought of as a “Network of Networks” containing a group of standards ‘under its hood’. The Internet, however, was not widely used outside of Government and some Educational facilities, until the mid 1990’s. Also during this early time period, “Electronic Messaging’” was just called ‘e-mail’…
As a Fax Server Architect (and Systems Administrator), one of my functions is to set up and maintain Least Cost Routing tables. If you have fax servers spread across several states (or countries), you want to route the fax jobs to minimize Toll Costs. This requires knowing about Telephone Area Codes and staying on top of new Area Codes being added. If there are also geographic areas that you want to block (i.e., Caribbean Islands), you also need to know which specific Area Codes are assigned to those areas. Most of the Caribbean Islands are included in the North American three-digit Area Code Numbering Plan, used in the United States and Canada. Long Distance routing is not quite as confusing of an issue as it used to be, when you had one telecommunications company providing your local service, but having to use a separate telecommunications company for long distance calling, particularly between LATA’s (Local Area Transport Area) Boundaries. LATA’s were established as part of the AT&T breakup, in 1984, defining which calls can be placed by your local telephone company (Baby Bells) and which ones required a Long Distance provider. Most telecommunication companies now support specific compliance rules allowing them to provide both Intra-LATA and Inter-LATA calls. There are close to 200 defined LATAs…

If you have a business printer, you know you can’t afford to have it go down and not be able to get it serviced. And it gets a workout you know you are going to have issues with it at some time. So, you buy a service contract.
Might we suggest that you buy an Oki Data printer instead?
First, one major mean of preventing printer failures is buying a printer that can stand up to the environment. A printer that is not likely to fail in the first place. Oki has a reputation for building tough printers. If you need confirmation, look at the computer system in a dusty, grimy environment such as an auto repair shop. Chances are, you will see an Oki Data printer attached to it. In terms of an office printer, instead of an intricate imaging system with numerous moving parts and inherently subject mechanical issues — Oki replaces the traditional laser and rotating mirror and lens system with a stationary array of LEDs (light-emitting diodes) as its light source. Fewer moving parts means fewer mechanical failures.
Second, Oki is offering 60 months of protection—parts and labor, including transfer belt and fuser replacement—with on-site expert repairs nationwide, and a recycling program that’s easy and eco-correct on their MC700 Color MFP Series (MC770, MC780, MC780f and MC780fx) and MB700 Monochrome MFP Series (MB760, MB770, MB770f and MB770fx) printers. So, instead of having to purchase extended service contracts for years — service which is generally provided by a third party who may or may not have an official sanction of the printer manufacturer — you can get 5 years of protection provided by the manufacturer.
What do you do and where do you go when your organization needs an IP address for its network? One option is to go to your ISP and obtain a dedicated IP. But where do they get them? And can you bypass your ISP and get an IP directly? In a blog article entitles “How IPs are legally and illegally exchanged” author Sam Walt gives an overview of the process, the players and what businesses need to know about the process when they decide they need additional IP addresses.

According to the 2014 IDC EMC Digital Universe Study, the digital universe is doubling in size every two years. The amount of data we create and copy will reach 44 zettabytes (44 trillion gigabytes) by 2020. Over two thirds of that 44 zettabytes is unstructured data generated by end users, yet 85% of that user-generated content is managed by an enterprise IT department at some point in its lifecycle. This explosive data growth is forcing companies of all sizes to explore more efficient data storage strategies which allow them to deliver storage services at cloud scale, allow them to meet new application and user demands while providing operational efficiency at scale. These demands are requiring companies to take a new approach to information storage.
What is that approach? Our friends from EMC have the answer to that question: ViPR Software-Defined Storage.
What is ViPR Software-Defined Storage? In short, it is a unified storage platform that provides a single control plane for multi-vendor, heterogeneous storage systems. The ViPR Software-Defined Storage platform forms the infrastructure that hosts ViPR Services, which support object, HDFS, and block storage on commodity hardware. The folks from EMC have made their white paper entitled “VIPR SERVICES STORAGE ENGINE ARCHITECTURE WHITE PAPER: Deploy a modern hyperscale storage platform on commodity infrastructure” available for you which details this solution. After you have read this informative document, we encourage you to contact your local EMC representative or authorized reseller, visit the EMC website, or explore and compare products in the EMC Store to learn more about EMC products, services, and solutions and how they can help solve your business and IT challenges.

Vulnerability management is a key element of cyber security management. Cyber criminals take over user computers by writing computer programs that “exploit” vulnerabilities in operating systems (Windows, Apple OS, etc) and application programs (Adobe Acrobat, Office, Flash, Java, etc). When software companies find a vulnerability, they usually issue an update patch to fix the code running in their customer’s computers.
Citadel Information Group publishes our Weekend Vulnerability and Patch Report to alert readers to some of the week’s important updates and vulnerabilities. Our focus is on software typically found in the small or home office (SOHO) or that users are likely to have on their home computer. The report is not intended to be a thorough listing of updates and vulnerabilities.
