Semtech Announces New Features for BlueRiver™ Platform

New BlueRiver firmware equips Pro AV manufacturers and installers with additional capabilities to transform matrix switching with SDVoE™

CAMARILLO, Calif., May 1, 2019 — Semtech Corporation  (Nasdaq: SMTC), a leading supplier of high performance analog and mixed signal semiconductors and advanced algorithms, today announced immediate availability of an updated feature set for its BlueRiver™ AV-over-IP chipset. The new firmware allows manufacturers of BlueRiver-based AV transmitters and receivers to remain at the forefront of the migration from traditional matrix switching to networked distribution solutions in Pro AV applications.

“BlueRiver technology has forever changed the dynamics of the Pro AV industry since OEMs are now able to replace proprietary AV matrix switches with Ethernet networks that dramatically deliver better price, performance, flexibility, and scalability,” said Don Shaver, Vice President of Video Products for Semtech’s Signal Integrity Products Group. “In this latest release of BlueRiver firmware, we are delivering further enhancements so our customers can continue to meet the 4K signal distribution requirements across the full range of market segments from residential and enterprise to rental and staging to command and control.” 

New BlueRiver capabilities enabled in firmware release 4.0 include:

  • Thumbnail Source Preview Streams: Thumbnail streams are now available from both NT1000 and NT2000 TX devices. The new thumbnail stream allows control software to implement a source preview function that is enabled and started through the BlueRiver API as either a unicast or multicast stream. The stream is a standard RTP (Real-time Transport Protocol) stream and contains a low resolution (320x180) YCbCr 4:2:2 uncompressed copy of the video source with controllable frame rate between 0.5 fps and the original source frame rate. 
  • Bitmap Overlay: Two color bitmap overlay function with transparency control is now available for NT2000 RX and TX devices. A monochromatic bitmap with defined foreground and background colors and transparency value for each can now be sent to either NT2000 RX or TX device via a BlueRiver API command. Maximum bitmap size is 64K pixels. For larger overlay, bitmaps can be enlarged using 2x or 4x pixel replication.
  • Dolby Vision Support: Dolby Vision Meta data is now transported between a Dolby Vision source to a subscribed RX that is connected to a Dolby Vision capable display.   
  • NBaseT Support (AQLX107): This release enables NBaseT support for the Aquantia AQLX107 integrated network PHY.  The network PHY can now be configured to work on networks operating at 2.5G or 5G speeds in addition to current 10G. The default network speed is initially configured through Production Assistant and afterwards the speed can be changed/re-configured through the API. 

About Semtech’s BlueRiver™ Platform

Semtech’s BlueRiver™ platform, brings the disruptive power of Ethernet to AV signal distribution, forever changing the dynamics of the Pro AV industry by allowing installers and OEMs to replace proprietary AV matrix switches with off-the-shelf Ethernet networks that deliver dramatically better price/performance, flexibility and scalability. The BlueRiver platform delivers a single programmable system on chip (SoC), which can be used to replace traditional AV/KVM extenders, matrix switchers, video wall controllers and windowing processors with a simple network of transmitters, receivers and off-the-shelf Ethernet switches. BlueRiver chipsets are the foundation of SDVoE technology offering zero-latency, uncompressed 4K streaming over standard Ethernet with unique support for HDMI 2.0a and HDR. They also integrate high-fidelity video scaling, windowing and audio downmixing. For more information, visit
