HDCP, High -Bandwidth Digital Content Protection: Beginners Guide


High Definition digital video allows users to experience high resolution, near perfect video content. As more content is delivered digitally, the content creators are increasingly concerned with content piracy because digital content can be perfectly duplicated. Therefore anti-piracy safeguards such, as High Bandwidth Content Protection (HDCP) is necessary in order for original content creators to protect their assets. In this article we will touch on the key points of HDCP

What is HDCP:

High-Bandwidth Digital Content Protection, HDCP, is an encryption scheme developed to defend against uncontrolled copying of digital content over high bandwidth digital interconnects such as DVI and the HDMI. The FCC approved HDCP as a “Digital Output Protection Technology” on August 4th, 2004.

A HDCP protected system consists of: 1) HDCP transmitter (DVD player for example), 2) the digital interface (DVI or HDMI), and 3) the HDCP receiver (your display monitor). In brief, the content is encrypted at the transmitter and the signal is passed to the HDCP receiver (display) via the DDC lines (in essence an I2C bus) where it is decrypted before viewing. HDCP requires that both the transmitter and the receiver comply with standards. If either one does not comply, the video will not be displayed properly. Incidentally, HDCP does not apply to analog interface such as component video although component video can be used to display high definition video.

Why should the consumer care about HDCP:

It is highly recommended that consumers be aware of HDCP and purchase sets that are HDCP compliant. Here is why. It has been speculated that the two competing high definition DVD standards HD DVD, and BLUE RAY, due out in 2006 will only deliver full resolution on HDCP protected outputs such as HDMI or DVI. If true, then users must have a HDCP monitor in order …

ICT Outsourcing Definitions and Types

ICT outsourcing can be said as one of the current trends for companies around the world to do their business processes. It is estimated that ICT outsourcing starts in the early 1990s where Kodak uses external partner to handle its ICT resources. As Kodak does not have the expertise in ICT, they hire another company to help them handle the ICT resources. This phenomenon occurs because companies would like to concentrate their core business functions among other benefits. After merely 20 years, outsourcing is now needed by a lot of companies mostly at customer support and also back-office processes and this affects Malaysia as well. Currently, Malaysia is known as a main outsourcing hub for the world, where it is currently ranked third globally behind China and India in the outsourcing industry. This shows how significant outsourcing is to developing countries in Asia.

Outsourcing Definition

Outsourcing is defined as a concept of contracting out part of the organization’s business process to a third party that has the specific skills and services. The third party must have the skills needed by the organization so that the outcome of the outsourced job is as expected. Outsourcing can also be explained as the movement of one or many business functions of a company including its assets to an outside service provider who gives a defined service for an agreed duration of time and payment on a written agreement.

From these two definitions, we can see that outsourcing can be defined with the following characteristics:

1. A company transferring one or many business process to a third party.

2. A third party has the skills and services required for the business process.

3. Has an agreement or contract between the two parties on the price and expected outcome.

An Introduction to Video Surveillance Recorders – Definitions, Types, Characteristics, Differences

The Video Recorders came with the camera and monitor first, closely followed by the Video Cassette Recorder (VCR), technology then brought us the multiplexer, which allowed several streams of video to be recorded onto the same tape and separated out into discrete and viewable streams. Nowadays there are different types of Video Recorders such as DVR and NVR. One of the problems the user must face when choosing a security system is whether or not they want to record with the NVR or DVR.

In this article we provide a brief description of the most important types of Video Recorders such as DVR and NVR.

Digital Video Recorder

DVR is defined as Digital Video Recorder, a device that records video from analog cameras to one or more hard drives. The videos from IP cameras can be recorded on DVRs but a codec is needed for each camera to convert the IP video stream back to an analog signal so it can be recorded. Some DVRs connect to the network and can be viewed using the camera.

DVRs have the following internal components:

1- An analog to digital converter, or encoder, which converts the analog video signals into the digital domain.

2- Digital storage, usually hard disks, where digital representation of the analog signals is stored and is ready for use.

3- A database, relating the digital information to references; time, alarms and other metadata, enabling the video information to be retrieved and displayed quickly and easily.

4- Digital to analog conversion and replay controls.

5- These are usually found more in Smaller, standalone DVRs and less common in enterprise level DVRs.

6- An operating system, which runs the whole DVR.

7- A computer network interface, found in more recent DVRs, to allow the DVR to be interrogated remotely.

DVRs have …

Reasons Why The Global Environmental Challenges Call for International Collaboration Among Scholars

The environment is the haven for human life. Its wanton degradation in this age calls for the most urgent attention by scholars from all fields. Many environmentalists and enthusiasts for the conservation of biodiversity like myself believe that designing effective strategies to arrest this canker of deleterious attitudes and activities of people requires a pluralistic and multidisciplinary approach.

Relying solidly on a truncated approach to only science and technology for solutions to the global environmental menace cannot yield the most benefits. This is largely due to the multi-faceted nature of the global environmental challenges which call for a good collaboration between the various academic disciplines.

To illustrate, the world needs economic and mathematical insights from economists and mathematicians on how to effectively manage the biodiversity resources, setting the right measure between usage and conservation (sustainability). The scientists, engineers, and technocrats must come out with new technologies such as biomimetics and other biotechnological approaches to sustain the endangered species in our environment. Artists must beef up the sensitization campaigns through their well-designed communication design tools. Anthropologists and culturists and religionists must strategize on how to change the weak and / or bad behavioral attitudes of people by picking powerful lessons from their cultures (norms, religious beliefs, values, ethics, by-laws) to appealing to their morals and influence them to engage in environmental friendly activities, protecting nature which humans serve as trustees or stewards. The historians must help us trace what went wrong in nibbing the global environmental situation in the mud. This would reliably inform us what went wrong and how we can change the wrong decisions humans made in the past, so that the past would not continue to haunt us. The agriculturists must strategize and inform us on improved agricultural practices that would not worsen the global environmental situation, but …
