Live Video Streaming: How It Works

December 5, 2018

Let’s talk about the process of live video streaming.It starts at the camera. Today’s cameras are digital and can capture images at a stunning 4K resolution (2160p). This resolution requires a very high bitrate to support the “raw” digital video signal coming out of the camera, so cables used to transfer this signal must be able to handle large amounts of data. HDMI or ethernet cables can be used in some cases. But most often, a 4K signal transferred over long distances requires an SDI cable that can manage the bandwidth requirements.Some live streaming is done with a smartphone, but more serious live productions employ additional cameras. Common live productions often use a three-camera studio setup. These cameras, and other video sources, are connected to a switcher that transitions between them. Audio for a production is transferred to a mixer via XLR cables. Generally, the switcher adds the audio from the mixer into the final output signal. It may also include the ability to add graphics, titles, and even animations. The switcher could be hardware, software, or a little of both when capture cards are required.

Why Shares of AMC Entertainment Are Surging Today

Article | April 28, 2020

It was just two weeks ago that it looked as if the COVID-19 pandemic would push AMC into bankruptcy, as forced theater closures shut off revenue to the world's biggest cinema operator. The company also slashed its dividend, and executives all took pay cuts to help conserve cash. Investors should still be wary, even if AMC is able to open many of its theaters sooner than the mid-June date it had been eyeing.

4 Stocks To Buy To Invest in Virtual Reality

Article | June 13, 2020

The virtual reality market has been hailed as the "next big thing" for decades, but VR has repeatedly disappointed consumers with mediocre hardware products and software experiences. But in recent years, a wave of refined devices narrowed the gap between consumer expectations and reality. The VR market's future has yet to be written, but investors who believe in this budding market should consider buying these four tech stocks. Sony's PlayStation VR is the best-selling VR headset in the world with over 5 million shipments since its launch in October 2016. That only represents a sliver of Sony's installed base of 110 million PS4s, but that foothold has encouraged developers to produce more stand-alone VR games and add-on experiences for PS4 games.

Music and podcasts are competing for the same time

Article | May 28, 2021

The pandemic changed media consumption.Consumers acquired an extra 12% of entertainment timeand though everything was up, some categories grew much faster than others. One of the biggest gainers was spoken word audio, with podcasts and audiobooks seeing dramatic rises and while music hours grew too, the increase was below 12%, which means that music lost share. In the current entertainment environment of plenty this may be an academic concern, but when life returns to some form of normality (commutes, going out, gyms etc.) some or all of that extra 12% of entertainment time will go, which means that growing by less than the market average could translate into decline.

Why video streaming needs to stop fighting the last consumer war

Article | May 28, 2021

Video streaming services have achieved mainstream engagement, with binge viewing now eclipsing linear TV viewing as the leading form of TV show consumption. While the digital disruptors may revel in their newfound status as the masters of TV consumption, and the TV and film industry are forced to adapt to this new reality, a subtler shift in mindset needs to occur. Streaming services, led by subscription video on demand (SVOD) hegemon Netflix, still operate in the mindset of having a digital native consumer base. For these streaming incumbents, the success of SVOD still rests upon their ability to appeal to younger consumer bases who have a) grown up in a digital environment, and b) are by definition young and eager for new and constantly evolving consumer experiences. Add to this the post-second world war presumption that popular entertainment should always be youth-centric focused, and streaming is still de-facto a youth-orientated proposition.
