SoundBridge is a hardware device from Roku, Inc. designed to play internet radio or digital audio streamed across a home network, over either Wi-Fi or ethernet. SoundBridge devices directly browsed the Radio Roku guide. As of 2008 all Roku SoundBridge products were discontinued; Roku focused on IPTV. As of January 2012, the SoundBridge was no longer available from Roku. As of May 2018, internet radio functionality was no longer supported by Roku. The music is made available by a streaming server, usually a PC running media software. The SoundBridge had a high resolution vacuum fluorescent display and was compatible with various media servers, namely servers using Apple Computer's Digital Audio Access Protocol; popular servers are iTunes, or mt-daapd, Windows Media Connect, Rhapsody, SlimServer and UPnP (Universal Plug and Play) compatible servers such as TwonkyVision. Some of these servers run not only on PCs, but also on NAS devices like the Linksys NSLU2, so a SoundBridge could be operated without a PC. Models There were several SoundBridge models: The M1000, the M500 and the M2000. There was also a tabletop model called the SoundBridge Radio that had built-in speakers, an AM/FM radio, and an alarm clock. SoundBridge models sold in most countries were manufactured and sold by Pinnacle Systems, under a license from Roku. Although some Pinnacle models were similar or identical in hardware, Pinnacle didn't have a licence for the DAAP protocol, so Pinnacle models couldn't directly connect to iTunes. Pinnacle and Roku promote the Firefly Media Server as an alternative that offers similar functionality. Pinnacle models include: SoundBridge (one version identical to Roku SoundBridge M1001, another known as M1001HR with the higher resolution 280×32 pixel display as used in the SoundBridge Radio) SoundBridge Radio (identical to Roku SoundBridge Radio sans native iTunes support) Soundbridge HomeMusic - M400PX (character-based LCD - 16×2 characters; no Ethernet; no digital output; SD card slot; low-cost plastic housing in place of aluminum extrusion on original models) Those sold in the US included: M1001 SoundBridge (bitmapped VFD display - 280×16; similar to original M1000 model(see note)) R1000 SoundBridge Radio (bitmapped VFD display - 280×32; AM/FM tuner; SD card slot; built-in speakers) M500 SoundBridge (character-based LCD display - 40×2 characters) M1000 SoundBridge (bitmapped VFD display - 280×16) M2000 SoundBridge (bitmapped VFD display - 512×32; larger, enclosure with very large display) WPA support Firmware version 2.7 supported Wi-Fi Protected Access, but only for the M1001, the SoundBridge
