In the first two parts of this blog series, we’ve looked at how Semtech’s BlueRiver® platform, the core technology that powers Software Defined Video over Ethernet (SDVoE™), can replace the traditional matrix switch for AV distribution, and with fully integrated USB connectivity, BlueRiver supports more advanced KVM switching applications, typically deployed in control centers and for remote desktop applications. In part three of the BlueRiver applications for Pro AV blog series, we’re going to explore how the powerful integrated image processing engine in the BlueRiver ASIC can enable cost effective video wall and multiviewer applications, removing the need for costly dedicated equipment, while still delivering a high performance, low latency IP-based AV distribution system.

The BlueRiver® platform is Semtech’s award winning technology for AV-over-IP, which is one of the fastest growing segments in the Professional AV signal distribution market. As the core technology that powers Software Defined Video over Ethernet (SDVoE™), BlueRiver has been demonstrated to be the only AV-over-IP technology that can provide matrix switch-like performance, delivering pristine 4K resolution video with imperceptible latency, along with multichannel audio and control signals, such as USB, Infrared and Consumer Electronic Control, all over standard 10 Gigabit Ethernet networks using a common control Application Programming Interface (API).

今回は、プロ用AV向けのBlueRiverアプリケーションブログシリーズの第2回目として、従来のマトリックススイッチのトポロジーを使用するアプリケーションにおいて、SDVoE がいかにコスト効率が高く、機能豊富なAV-over-IPシステムを実現しているかを見ていきます。

Since its official launch in early 2020, the BlueRiver® ASIC has been the bedrock of all new product developments for Software Defined Video over Ethernet (SDVoE™). From standalone encoders and decoders, to HDMI wall plates, the ASIC has provided a lower power and cost effective platform from which our customers can expand their product portfolios. With full integration of USB, designed for connecting and routing USB devices such as keyboards, mouse and track balls, BlueRiver sets a new benchmark for KVM over IP applications.

When the COVID-19 pandemic struck in early 2020, there was a general feeling that it would all be over in six months. Few expected the global shutdown of live events and professional sports. Concert tours were postponed and sports arenas stood empty as the effects of the pandemic rolled on into the year. I had bought tickets to see the My Chemical Romance reunion tour in September 2020, for my son Max’s 18^th birthday. But of course, it’s been postponed (twice) and it looks like I’ll be taking him for his 20^th birthday instead! Pro sports are starting to open up in many countries, and people like me are itching to go to concerts to see our favorite bands, comedians and theater productions, and be immersed in the collective cheers and applause of the audience again. In the immortal words of the late, great Freddie Mercury, “the show must go on!”

90年代初頭から半ばにかけてDolby Laboratoriesで働き始めて以来、私はよく「オーディオ専門家」と呼ばれてきました。しかし実際には、キャリアの大半をビデオ技術に費やしてきました。最初はシリアルデジタルインターフェース（SDI）、最近ではSemtechの受賞歴のある BlueRiver® technology for Pro AVによって実現するSoftware Defined Video over Ethernet（SDVoE™）に取り組んでいます。それでも、私はオーディオのあらゆることに関して関心があり、製品ラインのオーディオ機能を強調することに重点を置いています。こうした要素は見過ごされがちです。

Semtech's BlueRiver and Audio Over IP

The COVID-19 pandemic has highlighted the need for higher education establishments to adopt hybrid styles of learning, providing the benefits of in-room learning to remote students. The Audio Visual (AV) experience is a major component of this hybrid approach, combined with the flexibility of high performance networks, to deliver the most stimulating and immersive experience for both teaching staff and students. As the world recovers and students go back to school, there may still be the need to reduce class sizes for social distancing purposes, and therefore, “extend” the teaching experience beyond the single classroom, with many students still participating remotely, either from different rooms or from home.

I designed my first product using the Serial Digital Interface (SDI) back in 1996, and little did I know that this fledgling coax-based video interface standard would dominate my career for the next 20+ years. Back then, SDI was limited to carrying Standard Definition (SD) digital video at 270 Megabits per second (Mbps), but would evolve to higher and higher data rates to carry High Definition 720p, 1080i and 1080p, and most recently 4K Ultra High Definition (UHD) video, at cable lengths that were not thought possible. The convenience of a low cost single conductor coaxial copper cable, capable of carrying 4K video up to 100m has meant that SDI has become the de facto AV connectivity of choice in markets such as broadcast, Pro AV, medical and surveillance.

With the move to a more distributed workforce as well as an increasing number of staff permanently working from home, businesses are opting for smaller huddle rooms for ad hoc meetings and remote collaboration. Also taking advantage of the power of today’s personal computing technology, businesses large and small are relying less and less on dedicated, permanently installed video conferencing systems. These days, it is quite commonplace for users to drive the meeting and room technology using their own devices, and collaborate using the latest video conferencing software tools. This is often referred to as a “Bring Your Own Device” meeting, or simply BYOD. However, since the entire meeting experience relies totally on the user’s device and meeting software, such as Microsoft Teams or Zoom, this application is more often termed BYOM for “Bring Your Own Meeting,” with users simply benefiting from the available audio and video peripherals of the meeting space they are in.
