HDBaseT in HDMI Extenders Over Cat5e/6/7 Cable

The main drawback of HDMI as an A/V connection standard, when it comes to high definition video distribution, is cable length limitation. Installation costs quickly add up when you consider HDMI cables, control cables and HDMI repeaters for solving distance limitation. To cope with this limitation, a multitude of HDMI extenders over standard cat5e/6 cable became available – each of them providing proprietary solutions to support HDMI extension along with different control signals including CEC, IR, RS232, USB. The downside in all these implementations is that 150 feet proved to be the maximum distance for 1080p/24bit/60Hz resolution, with full HD support guaranteed well under 100 feet. With growing popularity of 3D formats, the need for a new technology became apparent.

HDBaseT is a new connectivity technology optimized for home and commercial multimedia distribution promoted by HDBaseT Alliance. The cornerstone of HDBaseT technology is the “5Play” feature, which means transmitting full uncompressed high definition video, audio, 100BaseT Ethernet, power, and various control signals through a single standard 100m/328ft Cat5e/6 solid cable. HDCP is also handled by the technology.

HDBaseT supports TV and computer video formats including standard, enhanced, high definition and 3D video, as well as all audio standards. HDBaseT delivers full HD/3D and 2K/4K uncompressed video in a point to point connection or a single to multipoint distribution supporting both daisy chain and star topologies. When cascading, extension limits can go beyond 100m/328ft – up to eight additional 100m/328ft runs can be combined. This flexibility makes HDBaseT an ideal commercial technology for applications such as digital signage.

HDBaseT supports 100Mb Ethernet, enabling televisions, hi-fi equipment, computers and other devices to communicate to each other and to access stored multimedia content. Different types of control signals are also supported by HDBaseT technology, starting from Consumer Electronic Control (CEC) that operates basic functionality such as power-on, power-off play and stop, to RS232, USB and infrared (IR) that operate remote equipment even when located in a different room. This large variety of control signals gives equipment manufacturers and integrators the flexibility to choose the solution that best meets their needs.

The latest addition to the HDBaseT 1.0 specification is Power over HDBaseT or PoH. This enables the transfer of DC power, along with data signals, over a single Ethernet cable in a manner similar to Power over Ethernet (PoE). PoH safely delivers up to 100W over four pairs of Ethernet cable, which allows power to be supplied to the attached devices through the cable, requiring no additional power supplies. The latest Energy Star 5.3 Specification restricts all TVs to 108W of power consumption, regardless of screen size. Energy Star 6.0 Specification targets a cap of 85W for all TVs. At these levels, HDBaseT has ample power delivery capabilities for supporting even large displays.

Network Technologies Inc (NTI) integrates the HDBaseT technology into its new line of HDMI extenders. The ST-C6HDMI-HDBT extender supports full HD/3D extension to 328ft, HDCP, CEC, IR and optionally SPDIF. The ST-C6USBHE-HDBT supports all of the features listed for ST-C6HDMI-HDBT, plus 100BaseT Ethernet, RS232, and USB support for USB keyboard/mouse and an additional USB device, such as a USB touch screen monitor, USB CAC card reader or USB whiteboard. Both extender models require only one power supply to power the local and remote units, which can be attached at either end. SPDIF audio and USB are not standardized in HDBaseT technology; therefore NTI employs proprietary solutions in its extenders. The way power is delivered through the Ethernet cable is also a proprietary approach tailored to extender applications and provides flexibility at a lower cost.

Outsourcing Managed Document Review

Managed document review can aid you in your discovery process prior to a trial. As opposed to the discovery process after a trial, of course. Discovery is a critical part of any legal case, but in large corporate or class action cases, discovery can be extremely involved. If Bill Gates or Warren Buffet happen to be your client, cost isn’t an issue, but most of us aren’t fortunate enough to represent individuals with bottomless pockets. Inevitably the question arises, should you cut cost on discovery and allocate more resources to trying cases.

Cutting costs on discovery seems stupid, at least superficially. A single key piece of evidence can be the difference in a trial. Overlooking that piece of evidence can be catastrophic.

One problem in huge cases is that there are so many documents to assay that it is impossible to do if the client is billed at standard attorney rates.

Enter the managed document review process. You farm the task of reviewing documents to a third party source which bills at much lower rates. You specify parameters telling them exactly what they are looking for and what can be ignored. They separate the wheat from the chafe, leaving a much smaller pool of documents for you or your legal staff to review.

Managed document review is not infallible. If you are worried about extremely sensitive disclosures which may be highly damaging to a client, letting third parties examine documents is unwise. Smart reviewers must be used, but the smart the reviewers, the higher the cost.

For specialized subjects like science or accounting, cheap managed review is sometimes not possible. This is because only highly paid experts can even understand the documents. There is a duality in this situation. As even a lawyer can’t understand such documents, managed review by experts must be used.

There are document review companies in nations like India, where highly educated individuals accept low wages Americans never would. This can be a good option, but if be aware that if documents have not been scanned, then they must be shipped, which can be risky. Transferring documents electronically is far preferable.

More and more, converting documents to computerized files is preferred. High speed scanners rapidly convert documents into computer files, and then OCR is run. OCR stands for optical character recognition software, and it converts scanned images into readable text. Documents must still be read, but searches of documents using keywords is still very helpful.

Some lawyers view managed document review as a profit drain, and figure it is better to just have staff review documents and bill the client. A markup can be charged for the service. Also, the client doesn’t have to be told the task was farmed out, and can be unwittingly billed at standard legal prices.
