TEAC UR-Stream 4K/UHD Streamer and Recorder

Introducing A Stand-Alone Encoder & Decoder For 4K Live Streaming + Recording



TEAC UR-Stream 4K/UHD Streamer and Recorder

The UR-Stream is a 4K/UHD AV over IP streaming encoder and decoder that simultaneously records, encodes, streams, and decodes multiple 4K video streams (3840×2160) using High-Efficiency Video Coding (HEVC), a high-efficiency coding scheme that delivers H.264 video quality at half the bit rate. The UR-Stream live streaming encoder is compatible with popular standard streaming protocols, including HLS, RTMP, RTP/RTSP, Multicast, Unicast—all with RESTful API for integration into control systems in commercial AV installations. video quality at half the bit rate. The UR-Stream can record directly to the USB devices or SD cards via a front/ rear panel-loading slot. Recorded files can be automatically uploaded to an FTP server for creating backup copies, editing, or repurposing to the web. PoE+ functionality eliminates the need for AC adaptors in AV installations. Optional AC power supply sold separately where external AC power is required. Power can be also be supplied via the optional AC adapter (sold separately). Audio can be embedded from analog sources and de-embedded to drive networked audio playback for ceiling speakers,
or digital audio within the HDMI I/O can be used. An integrated installed output level configuration function and reference level switching function (up to +20dBu) allows reliable and flexible system structuring when streaming video. The Mac/Windows “DISCOVERY” app allows multiple UR-Stream units connected to the network to be managed from a simple Web-browser-based GUI. All configuration settings are saved within the UR-Stream devices, so that in normal operation no computer is needed for streaming or recording.

About TEAC

The guiding principle of TEAC is to enrich our society through our innovative products. TEAC is highly regarded for its video, image, and sound recording technologies, and now introduces medical imaging recorders for microscopic surgery. We have been contributing to society’s use of analog and digital recording since 1953, helping customers and partners with the technologies to record and playback sound, still images, and video images. We have been providing our Products to the healthcare industry for well over 2 decades. Examination images and procedure images are recently used to explain, educate, and present, therefore it is essential that medical videos are currently recorded and played at medical sites. We focus on the reliability and the convenience of use about “a function of record” and aim to show recorded images for explanation and education clearly regarding “a function of play” to satisfy the needs of medical sites, then we strive to research and development every day.
