SDI Is Dead: Long Live SDI!

Posted by Gareth Heywood on 15 April 2021

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.

AVX for “Bring Your Own Meeting” Applications

Posted by Gareth Heywood on 25 March 2021

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.

Not All Cables Are Created Equal

Posted by Gareth Heywood on 24 February 2021

When it comes to AV signal switching and extension over standard copper category cabling, Semtech offers two high performance platforms: AVX chipsets for point-to-point AV extension applications, and the BlueRiver® AVP series of devices for AV-over-IP and Software Defined Video Over Ethernet (SDVoE™) network-based applications. Both solutions take advantage of standard Ethernet technologies, typically operating at 10Gbps, to support transmission of high bandwidth 4K60 video with uncompressed image quality. However, when video bandwidth does not require the full 10Gbps, both AVX and AVP can operate at the 2.5Gbps and 5Gbps Ethernet rates. The benefits at operating at these lower data rates includes significantly longer cable reach over high performance category cable, or reuse of existing network cable infrastructure designed to carry lower data rate Ethernet.

从 AVX 到 BlueRiver® AVP:Pro AV ASIC 互操作性

Posted by Gareth Heywood on 05 January 2021

It’s been almost a year since the official launch of Semtech’s ASIC platform for Pro AV extension, routing and distribution. Two dedicated platforms were launched: AVX for point-to-point AV extension applications over copper category cable and optical fiber, and the BlueRiver® AVP series of devices for AV-over-IP and Software Defined Video Over Ethernet (SDVoE™) network-based applications. And what a year it has been! Despite the COVID-19 pandemic, customer uptake and product developments have certainly exceeded expectations, and 2021 will see the launch of an exciting range of Pro AV products powered by the new AVX and BlueRiver AVP ASICs.

探索 BlueRiver® ASIC:网络研讨会问答

Posted by Gareth Heywood on 15 July 2020

With the launch of the BlueRiver® ASIC at the beginning of 2020, the AV over IP landscape is being redefined by products offering new levels of cost, performance and interoperability. As the core technology for Software Defined Video over Ethernet (SDVoE™), BlueRiver is recognized as the only IP-based technology capable of providing true video matrix-level performance, with pixel-perfect image quality and ultra-low latency. Supporting a broad range of markets and end-applications, such as live events, esports, medical, high-end residential, and command and control, system designers can take advantage of the powerful SDVoE Applications Programming Interface (API) to develop application-specific software running on a common BlueRiver-powered hardware platform.

为什么 Semtech 的新型 AVX ASIC 系列是视听扩展的卓越解决方案

Gareth Heywood 发表于 2020 年 5 月 19 日

在 Pro AV 的世界中,当需要从 A 点传输视听内容到 B 点,且无法进行远距离标准布线时,点对点的电缆扩展技术就必不可少了。随着 HDMI 的问世,全带宽视听信号以数字格式通过屏蔽双绞线 (STP) 电缆高数据速率发送,电缆一般最长 20 米左右。HDMI 传送 4K 视频内容的速度高达每秒六吉比特 (Gbps)。随着数据速率的提高,在更长距离上传输的挑战也越来越大。HDMI 将视听连接转换为数字连接后不久,又有一项技术诞生,可通过标准的铜缆网络基础设施扩展这些信号,这就是 HDBaseT。

推出 AVX,用于 AV 扩展的 ASIC

Posted by Gareth Heywood on 11 February 2020

For most of my career at Semtech, I’ve been responsible for SDI-based products and technology, often extolling the features and benefits of copper-based, long-reaching audio and video (AV) signals. While SDI product lines matured into a meaningful business for the Signal Integrity Products (SIP) group at Semtech, there has been significant investment and record growth in optical fiber transmission technology for enterprise computing and communications. Fiber connectivity is now the backbone of worldwide communications with SIP optical products at the heart of this fiber revolution.
