March Meeting: Jampro Antennas and Design Considerations of TV Spectrum Repacking

Broadcast TV antenna manufacturers should make some good sales numbers in the next couple of years as the FCC forces broadcasters to shuffle channels again. This time around, the emphasis will be on broadband designs. Jampro has been working to make their antennas work on multiple channels with minimal wind loading. Many broadcasters will be looking at designs that make the best use of ATSC 3.0 as well. There are things to keep in mind you as broadcast engineers may not have considered, like OFDM Crest Factor and circular polarization for mobile coverage. Jampro logo

As a bonus, they plan to talk about their experience in Singapore with DVB-T2 and Single Frequency Networks.

Join us March 15 at 12 noon at KGTV, 4600 Air Way near I-805 and CA-94 in San Diego for the Chapter 36 regular monthly meeting. Jampro is buying lunch in the cafeteria.

Come on by, and bring a friend.

January 18 Meeting: LTE for Broadcast by Moseley

Sumit Singh of Moseley discusses LTE technology for broadcast microwave news at KFMB-TV.
Sumit Singh of Moseley discusses LTE technology for broadcast microwave news at KFMB-TV.

An attentive crowd at the KFMB studios heard Sumnit Singh make a case for using the technology developed for consumer mobile devices to relay news audio and video to broadcast outlets over private networks. It should be interesting to see if stations step up to the plate to capitalize this evolution, or if an organization will step up to finance the movement and then resell to broadcasters, or if the technology will die on the vine before being rolled out.

Many thanks to Sumit Singh for traveling to San Diego and for buying our lunch. Continue reading January 18 Meeting: LTE for Broadcast by Moseley

November 2016 Meeting: Lawo and the Virtual Radio Station

When broadcasters swap CD’s, cart machines, turntables and audio consoles for PC-based digital playout, mixing & processing systems, we call that Virtual Radio. At our next meeting, guest speaker Bill Bennett, Lawo’s Radio Applications lead in the U.S., will describe virtualization in greater detail by outlining the real applications in use today.  He’ll explore how broadcasters may now reap operational benefits and gains by capitalizing on I.T.’s investment in R&D and will discuss virtualization’s anticipated role in content creation and broadcast workflow in the future.

Homegrown Pico Digital to Talk About Their Station in a Box

Many, if not most, radio stations these days have an Xpress box to bring them some flavor of satellite-delivered content, whether a talk show or syndicated music broadcast. But did you know these receivers are made in San Diego? Did you know they can be programmed to operate as self-contained radio automation systems? What can networks do with these store-and-forward devices?

Damon will talk about their watermarking and monitoring technology as well.

Pico Digital started as Pico Macom in 1969, selling TV modulators and related RF devices for the cable TV and hospitality markets. They still make and sell sophisticated cable RF modulators, but have widened their offerings to include radio and TV IRDs.

Damon Semprebon of Pico Digital will give a talk on the capabilities of the Xpress line of receivers and other Pico products of interest to TV and radio broadcasts Wednesday, August 10th at 12 noon at KFMB, 7677 Engineer Road in San Diego. We’ll have a small lunch provided by Pico Digital, then the presentation. Members and guests welcome.

About Our Presenter

Damon Semprebon has 30 years experience in technical project management, product development, and other technical services. Before coming to Pico Digital a year ago, he spent 25 years at the San Diego company variously known as Comstream, Tiernan, Radyne, Comtech, and International Datacasting.

May 18 Meeting: RTS and Dante

By now, you’ve likely heard about the audio-over-IP protocol called Dante. It’s low-latency so that you can use it with live audio, and can pass through most data switches. Many of the largest broadcast suppliers have adopted it. RTS, the intercom company that has been around since the 1970s, will come to town and explain why their latest generation of products is knee-deep into Dante.telex-rts-logo

They can answer a few questions you might have:

  • What data rates are used?
  • What is the packet structure?
  • Does it play well in my network?
  • How many audio channels can fit at a time?
  • What is its latency? Will my air staff hear an echo?
  • When should I favor analog audio, if at all?
  • Are there phone apps that work with intercom systems now?

Jeff Shorsher of RTS/Telex will sort out these topics and more in a meeting Wednesday, May 18 at 12 noon at KFMB Stations, 7677 Engineer Road in Kearny Mesa. Join us for a lunch provided by RTS, then a general meeting and presentation. Members and guests are all welcome.

March 16th Meeting – Cobalt Digital

Some of what’s going on in TV broadcasting would have been impossible just a few years ago. For example, stations are now converting their news or event ticker text to speech on a secondary audio channel for the visually impaired, bringing them information never before heard. We can now normalize audio levels within an MPEG transport stream.

Cobalt started as a video accessories company in the analog broadcast era, but has taken on serial digital and now transport stream processing. Come see what solutions they have to offer. Cobalt Digital visits Chapter 36 Wednesday, March 16 at 12 o’clock noon at KGTV, 4600 Air Way, San Diego to discuss these technologies and more. Cobalt will provide lunch.

In his role as Cobalt Digital’s Director of Product and Business Development, Jesse Foster helps to develop new products, does technical sales, marketing, and customer support. He is also a fiber optics and compression product specialist. Before joining Cobalt nearly four years ago, Foster spent eight years at Evertz, two in customer service and six in a senior technical sales position. Foster is a certified fiber-optic technician well-versed in large video-routing systems, multiviewers, video and audio processing, fiber optics, RF, streaming media/compression, live production, postproduction, and broadcast.

January Meeting – DVEO, Local Company with Cool Tools

Outfitting a TV channel with playout automation can be a real challenge. “Channel-in-a-box” solutions turn out to be more expensive than advertised because you end up buying a dizzying array of modules and licenses to get EAS, graphics layers, dynamic content, satellite network sources, and ASI inputs and outputs. Your vendor can make your product ownership experience frustrating because support is overseas or you have to pay for a big contract.

Local supplier DVEO is gaining traction with some interesting solutions for broadcasters of all kinds, whether a cable station, LPTV station, government channel, or a subchannel at your major affiliate TV station. DVEO will appear this month to show us modern tools for inserting commercials, network and local media, graphics layers, and even EAS into an SDI or ASI stream.

We’ll also get a look at a 4K resolution brand spanking new H.265 HEVC encoder and decoder pair. While you may not think of 4K as a practical format for broadcast yet, you can still use this codec for transmission of conventional HD video at about half the bandwidth of H.264.

Join us Wednesday, January 20 at 12 noon at KFMB, 7677 Engineer Road in Kearny Mesa, San Diego. DVEO will buy us lunch.
