Acme Revival is an independent repair network that operates separately from the manufacturers whose devices we service. Our independence enables a repair model that exists beyond manufacturer-controlled strategies, while preserving the ability to work with manufacturers where appropriate.
Epiphan Systems Inc., operating as Epiphan Video, is a privately held professional audiovisual technology manufacturer specializing in hardware and cloud solutions for capturing, encoding, recording, producing, and streaming high-resolution video. Its product portfolio includes the Pearl family of all-in-one video production, recording, and streaming appliances; AV.io and other USB video capture devices/frame grabbers; and associated cloud management services. Its equipment is used in live event production, lecture capture and education, corporate video, training, healthcare, worship, manufacturing, security, and other professional AV applications. Epiphan is particularly known for its Pearl video recording and streaming systems and plug-and-play video capture hardware, with integrations into platforms and control systems such as Panopto, Kaltura, Q-SYS, Crestron, and Extron.
Epiphan hardware may fail to detect or capture an attached HDMI, SDI, DVI, or VGA source, resulting in a blank image or "No signal detected" condition. Causes commonly include signal-format incompatibility, cabling/source issues, HDCP-protected HDMI, or input-detection problems.
AV.io and DVI2USB capture devices may not be recognized by the host computer or may disappear after reconnects, sleep, boot, or firmware operations. Compatibility problems with particular USB host controllers, USB 2.0/3.0 connections, cables, and host operating systems are repeatedly documented.
Captured audio may be completely absent or exhibit popping, clicking, distortion, or other artifacts. Epiphan documents these problems across Pearl and AV.io hardware, with causes including sample-rate settings, USB-controller or chipset compatibility, capture applications, and operating-system behavior.
Capture or streaming hardware may deliver a lower frame rate than configured or intermittently drop frames. High system load, insufficient USB bandwidth, high encoding workloads, network limitations, particular USB controllers, and some input frame rates can trigger the problem.
Pearl-family streams may stop, intermittently break up, or exhibit dropped video during transmission. Packet loss, insufficient network bandwidth, network configuration, excessive bitrate, and incompatible downstream equipment are documented contributors.
Pearl-family systems may refuse to start a recording or encounter recording-related problems when storage capacity or storage availability is insufficient. File-format and media-player compatibility can also make otherwise completed recordings appear unusable or fail to play correctly.
Firmware upgrades can fail on Pearl and AV.io hardware, and an interrupted AV.io update can leave the capture device undetected until firmware recovery is performed. USB-controller incompatibilities, virtual machines, interruption during flashing, and other host conditions are documented causes.
Some Epiphan hardware may fail to boot or start correctly after power-on. Pearl documentation identifies connected USB storage and, on some models, attached HDMI-output equipment as possible startup conflicts, while AV.io documentation identifies certain USB cable/host combinations that can prevent normal booting.
Epiphan capture hardware can incorrectly detect input resolution or produce black, distorted, artifacted, frozen, or otherwise corrupted video. Documented triggers include application incompatibilities, USB host controllers, particular signal formats/frame rates, scaling configurations, and operating-system-specific issues.
