AVXT for “Bring Your Own Meeting” Applications

Gareth Heywood 发表于 2021 年 3 月 25 日

随着工作人员的办公地点越来越分散,以及越来越多员工长期在家办公,企业现在倾向于选择小型会议室来进行临时会议和远程协作。由于当今个人计算技术的兴起,专用、永久安装的视频会议系统不再像以前那样受大小企业的青睐。如今,用户用自己的设备来驱动会议,并使用最新的视频会议软件工具进行协作,这已经变得司空见惯。这通常称为“自备设备”会议,或简称为 BYOD。但由于整个会议体验完全依赖于用户的设备和会议软件(例如 Microsoft Teams 或 Zoom),因此该应用通常被称为 BYOM,即“自备会议”,而用户受益于所在会议空间中可用的音频和视频外围设备。

Not All Cables Are Created Equal

Gareth Heywood 发表于 2021 年 2 月 24 日

When it comes to AV signal switching and extension over standard copper category cabling, Semtech offers two high performance platforms: AVXT 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 AVXT 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.

From AVXT to BlueRiver® AVP: Pro AV ASIC Interoperability

Gareth Heywood 发表于 2021 年 1 月 5 日

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: AVXT 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 AVXT and BlueRiver AVP ASICs.

Why Semtech’s New AVXT ASIC Family is a Superior Solution for AV Extension

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。

Unveiling AVXT, the ASIC for AV Extension

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.
