HDBaseT to the Rescue!

HDBASET_blogJust in case full high-definition resolution isn’t enough, 4K is the next generation resolution that will deliver a whole new level of clarity at roughly four times the resolution of 1080p. Despite limited 4K content currently available to consumers, Samsung, LG, Sony, Panasonic and others are already selling 4K TV sets and widespread adoption is eventually expected.

4K covers two formats – 3840p X 2160p and 4096p X 2160p. While the latest standards support these resolutions while adding an audio channel and offering the ability to deliver 100 Mbps IP-based applications with an added Ethernet channel, there are some cabling and connectivity challenges to consider that include distance limitations, installation and testing. In this blog, Belden’s Paul Kish takes a look at how HDBaseT resolves these issues and is uniquely positioned to reduce the cost and complexity of delivering HD video.

HDBaseT over Bundled Cables

While HDBaseT is an ideal application for reducing cost and complexity of HD video delivery, it has been reported in the field that there are cases where multiple HDBaseT signals in separate cables that share the same pathway can interfere with one another causing a loss of signal or a degraded picture. To determine under what conditions a link failure can occur, Belden performed a controlled set of tests using commercially available audio/visual equipment from multiple manufacturers of equipment using HDBaseT signal transmission.

Triax Camera Lengths

Unlike digital video cables, the maximum length for triaxial camera cables is not defined in an official standard. All camera manufacturers have transitioned from analog to digital signal transmission for their cameras. However, to avoid limiting the length of cable that can be used, they are not transmitting the video signal according to digital video cable standards such as SMPTE 259M, SMPTE 292M, SMPTE 372M and SMPTE 424. Instead, they have developed their own way of transmitting signals for various systems, such as camera to repeater and repeater to base station.

Triax 8, Triax 11 and Triax 14 are the most common types of triax cables used. Designed specifically for HD cameras, these composite cables can multiplex audio and video signals and power. They meet all the requirements of the SMPTE 311 standard and are also compatible with industry standard SMPTE 304M connectors. Belden indicates the maximum length of these cables in our documentation.

Belden Standardises on Flame Performance

7804ECHBelden’s portfolio of SMPTE311 camera cables has included two low-smoke, no-halogen (LSNH) jacketed cables – 7804ENH that meets IEC 60332-1 single wire flame test and 7804ECH that meets IEC 60332-3-24 bundle flame test.

These cables are mainly used in buildings where flame performance plays a critical role. To ensure that our customers always have maximum flame performance and therefore less risk, we have decided to discontinue the 7804ENH cable and standardize on 7804ECH. SMPTE311 assemblies and pigtails will also now use the 7804ECH cable.

Welcome to the latest issue of our Broadcast Vision newsletter. We are well into the first quarter of 2015 and continuing to focus on helping our customers support the ever-increasing resolution of today’s broadcast transmissions. As HD resolution becomes the minimum and 4K resolution with four times the resolution of 1080p starts to take hold, Belden will continue to be your source for information and solutions that go the distance. In the meantime, happy reading!
