JVC Professional have announced that their camcorders can stream live broadcasts in HD quality.

Using JVC’s GY-HM650/850/890 camcorders, a new partnership with Zixi makes this possible. Compared to conventional transmission methods, the advantages of IP broadcasting technology take full effect in the field and make live video data transfer easier. In particular, ENG and EFP applications benefit from minimised technical effort, large cost savings, easy handling and more efficient workflows. Furthermore, signal transmission is secure and lossless, with minimal latency.

The first result of the cooperation between JVC and Zixi is an integrated IP broadcasting service included on the JVC GY-HM650, GY HM850 and GY-HM890 camcorders. There’s no need for any additional equipment.

Zixi’s streaming technology applies advanced content-aware error correction to compensate packet loss, which may occur during data transmission via wireless internet connections. In this operating mode, the decoder dynamically analyses internet link performance (Link Monitoring) and ensures that the camera will make bandwidth adjustments. If necessary, data packets are transmitted again with resultant latency being kept within tight limits. This advanced forward error correction is able to reliably compensate jitter and packet loss, up to 30 percent. By doing this, stable data streaming under difficult conditions is ensured – even if signal detection of conventional systems fails. For safety reasons, LCD monitor and camera viewfinder display streaming status and signal quality. On the receiving side, only a Zixi-compatible decoder or server is required. Using Zixi services, additional features such as time shift streaming, cloud-based recording and playback from the data cloud are also available.

Zixi technology is already in use by Over-The-Top (OTT) content platforms, internet and mobile video service providers, broadcasters, satellite and fibre optic network providers, news agencies, live sports producers, video conferencing systems for business and many institutions from different sectors.

Prokit has taken delivery of a new 1′ x 1′ LED panel light that is 4 times as bright as the original, market leading, Litepanels 1×1.

It’s the new ASTRA from …… Litepanels.

It is already attracting fans:

 Cinematographer, Kees Van Oostrum, ASC and gaffer William Russell used several Litepanels fixtures, including the new ASTRA 1×1 Bi-Color, on the second season of “The Fosters”*.  



“I’m a big user of Litepanels fixtures,” said Van Oostrum. “LED lighting gives me the opportunity to work very fast, and it’s very easy to control the light. The Fosters is a traditional stage show, but I still like to use a lot of LED lighting. I was able to add the ASTRA for the last episode of this season, which was fantastic.” The ASTRA 1×1 offers a light output up to four-times brighter than the company’s traditional 1×1, high CRI, and user selectable active or passive cooling modes. Designed with premium quality, surface mount LEDs paired with custom designed TIR optics, the innovative daylight to tungsten tunable color model is the first in Litepanel’s new innovative and affordable line of ASTRA panels. “With the ASTRA, I graduated into a much better light that I will be able to use in many areas where I couldn’t use an LED before,” continues Van Oostrum. “The ASTRA can replace the 575w HMI in many situations because it has an output that is so much brighter than the 1×1. It really saves a lot of time on set compared to a regular light. It goes up quickly, it’s easy to rig and adjust, and it can dim. “The ASTRA is beautifully executed. I love that it can be battery powered, so it’s totally independent from regular power sources, and that there’s a read-out on the back (optional accessory required), so you know exactly what you’re doing color-wise and intensity-wise. Litepanels made really great improvements with this light,” he adds.

*ABC Family produce The Fosters in the USA. It is a popular drama about a multi-ethnic family of foster and biological kids being raised by two mothers.

The good news is that the television industry is still reporting that “content is king”. We have heard this before of course, but it is great to hear that it is still the case. Whilst the internet continues to make the view ahead less predictable, the need for great content remains paramount.

The TV industry is continuing to debate what is next on the horizon, which is not surprising given the successes of content companies like Netflix and HBO. A recent report suggests that viewers are still eager for quality content, and they are prepared to pay for the privilege. Global pay TV revenues reached $245 billion in 2013, and are set to reach a record $281 billion by 2017.

Unpredictability is being exacerbated by the internet and the advent of Television 2.0. Now described as the Over-the-top (OTT) Multiscreen Landscape*, new opportunities for great content creation emerge daily. Television 2.0 is not only changing the way businesses operate — it is also fuelling changes in consumption, turning communal TV watching into an individually subscribed activity. Viewing is also moving from the traditional family room to personalised services on games consoles, smart TVs and mobile devices. As a result, prime time is becoming ‘my time’, as content is being made available typically within 24 hours of original airing, allowing audiences for these shows to extend, along with their locations.

There is a growing need for companies to build and retain the skill sets required to maintain a profitable and consistent multiscreen platform. As content providers have little or no desire to be software developers, they are looking to partner with individuals and companies that enable them to concentrate on what it is they do best — providing great content.

That’s where YOU come in – our Prokit clients.

The Prokit team will be at the IBC exhibition in Amsterdam over the next few days doing our best to find you great products and services to help you to fulfill our mutual goal: “Content is King”.



* OTT content is described as online video from services and operators that is distributed over a number of channels including fixed (e.g. to computers, connected CE, tablets) and mobile (e.g. smartphones and tablets) broadband – it is not associated with a pay-TV service provider subscription.

* Multiscreen services refer to the distribution of premium content from pay-TV operators to screens beyond the confines of a traditional set-top box or gateway device.

Happy Valley creator Sally Wainwright recently talked about why she doesn’t think sexism is as much of a problem in the UK as it is in America. She explained: “I think if you’re talented, and you’ve got what it takes, it doesn’t matter what sex you are. It seems to me it’s harder in America. There’s a lot more sexism in the American system, certainly on-screen. Women have to be very thin and very beautiful, whereas men can be much more eccentric; they can be old and fat. In the UK, we can portray women as they really are.”
