BoxCast offers end-to-end live streaming

By Jonathan Abrams

My interest in BoxCast originated with their social media publishing capabilities (Facebook Live,
YouTube Live, Twitter). I met with Gordon Daily (CEO/co-founder) and Sam Brenner (VP, marketing) during this year’s NAB Show.

BoxCast’s focus is on end-to-end live streaming and simplifying the process through automation. At the originating, or transmit (XMT), end is either a physical encoder or a software encoder. The two physical encoders are BoxCaster and BoxCaster Pro. The software encoders are Broadcaster and Switcher (for iDevices). The BoxCaster can accept either a 1080p60 (HDMI) or CVBS video input. Separate audio can be connected using two RCA inputs. The BoxCaster Pro ($990, shipping Q3) can accept a 4Kp60 input (12G-SDI or HDMI 2.0a) with High Dynamic Range (HDR10). If you are not using embedded audio, there are two combination XLR/TRS inputs.

Both the BoxCaster and BoxCaster Pro use the H.264 (AVC) codec, while the BoxCaster Pro can also use the H.265 (HEVC) codec, which provide approximately 2x improvement compared to H.264 (AVC). BoxCast is using Amazon Web Services (AWS) as its cloud. The encoder output is uploaded to the cloud using the BoxCast Flow protocol (patent pending), which mitigates lost packets using content-aware forward error correction (FEC) to mitigate lost packets, protocol-diversity (UDP and/or TCP), adaptive recovery, encryption and link quality adjustment for bandwidth flow control. Their FEC implementation does not have an impact on latency. Upload takes place via either Ethernet or Wi-Fi (802.11ac, 2×2 MIMO). The cloud is where distribution and transcoding takes place using BoxCast’s proprietary transcoding architecture. It is also where you can record your event and keep it for either a month or a year, depending upon which monthly cloud offering you subscribe to. Both recordings and the streams can be encrypted using their custom, proprietary solution.

At the receiving end (RCV) is an embedded player if you are not using Facebook Live or YouTube Live.

Switcher Studio intros Go app for mobile video creators

Switcher Studio’s flagship product allows users to create TV-style multi-camera productions using iPhones and iPads. Over the past year they have seen a trend developing — a new type of live video that started to gain adoption with the integration of live streaming on platforms like Twitter (via Periscope) and Facebook.

Many of these broadcasts tend to be more spontaneous and less pre-planned, so Switcher Studio set out to find a way to make these types of productions a better experience while enhancing the creation process for existing users.

The result is specifically designed for mobile video creators. Switcher Go includes advanced video features that let you go beyond “point-and-shoot” to create more engaging live and recorded video.

Switcher Go allows users to:
– Wirelessly connect to another iPhone or iPad to remotely control the camera from your pocket.
– Sync directly to Facebook Live or YouTube Now to quickly go live with one touch.
– Dial in advanced camera controls such as focus, exposure, white balance and more.
– Personalize video content by adding photos or video from your device’s camera roll while recording or streaming.
– Users will be able mark moments during broadcasts, then easily trim and share clips on social media. This ability is coming soon to the product.

In the next few months, Switcher Go users will have the option to upgrade their free account to add unlimited photos and videos from their camera roll and Switcher’s cloud services and desktop tools, currently only available in their pro Switcher Studio product.
