Features at a glance

Epiphan Pearl is a lightweight, portable, all-in-one live video production system with audio support over SDI and HDMI, or separately via professional stereo TRS audio.

Connect four HD video sources and simultaneously live stream each of them them to different end points. Choose to also create and stream custom multi-source layouts with branding and background matte of your choice. Record your custom videos and original sources for flexible post-production editing. Share the content over your network using multicast, or use a content distribution network (CDN) such as Akamai, LiveStream, StreamGuys, Wowza, or YouTube Live to share the results over the internet. Simplify integration with content management solutions (CMS) by populating metadata fields and configuring automatic upload of recordings to your network using SFTP, SCP, FTP, RSYNC or CIFS.

Pearl comes with a custom, reusable, hard-shell carry case with padding so it’s easy to pack Pearl and take it with you wherever you’re going.

  • Pearl automatically scales inputs to match your configured layout settings.

  • Add your corporate color as a background and your company logo

  • Provide track meta data such as the date, time, and presenter name.

  • Overlay video with timestamp information and other text.

  • Create a custom image to display when the channel does not have a signal or if your input signal is interrupted for any reason.

Video Display

  • Video output ports

  • (2) Mini DisplayPort with audio for local video display or larger confidence monitoring

  • Pearl has an RJ-45 Gigabit Ethernet port

  • Two USB 2.0 ports

  • Use the screen located on the front of Pearl to view the stream for confidence monitoring or connect Pearl to the local network to view the stream using a web browser.

Video and Audio Inputs

  • Pearl captures four video sources from either 3G–SDI, HD-SDI, SD-SDI, HDMI, DVI, and VGA inputs at their native resolutions and frame rates.

  • Audio input is supported over SDI and HDMI or through two TRS audio input ports.

  • Two HDMI ports capture HDMI and DVI signals, two VGA ports capture VGA signals and two SDI ports capture 3G-SDI, HD-SDI, and SD-SDI signals.

Streaming protocols

  • Pearl supports a wide range of streaming formats and protocols enabling it to stream video to media players across a variety of platforms and web browsers using industry standard streaming formats including HTTP, FLV, ASF, MJPEG and HLS.

  • Supports multicast streaming via UDP using RTP, MPEG-TS RTP, MPEG-TS and publishes to streaming servers (CDNs) via RTMP and RTSP.

  • Multi-encoding allows you to adjust the bitrate, frame rate and resolution of each stream to match the requirements of the video content and the platform on which the audience will view the stream.

Stream using Universal Plug and Play (UPnP) and Session Announce Protocol (SAP)

  • Media players, smart TVs, set-top boxes, digital signs etc. can play live streams and saved recordings from the Pearl via UPnP or SAP.

  • Streaming via UPnP and/or SAP is perfect for situations when the destination device is unattended. For example, when Pearl streams to a digital sign that continuously plays a video, if there is an interruption, the live stream resume feature automatically resumes the stream.

  • Pearl’s powerful processor lets you stream to many set top boxes/smart TV’s simultaneously without sacrificing video quality.

Video encoding with H.264, MPEG-4 and MJPEG

  • Pearl supports the most widely used video codecs to ensure maximum compatibility with commercial viewing software media players such as VLC and Adobe Media Player.

  • Use the default settings, or fine tune the operation to your application.

  • Video frame rate, encoding bit rate, and key frame interval are among several parameters available to tailor the encoding to your specific requirements.

  • Whether you are recording highly dynamic full motion video or slowly changing instrumentation displays, Epiphan Pearl enables you to direct the encoder to achieve optimal video quality while satisfying bitrate and file size constraints of your specific application and environment.

Supports audio codecs MP3, AAC and PCM

  • Pearl supports the most widely used audio codecs to ensure maximum compatibility with commercial viewing software.

  • Use the default settings, or fine tune to meet your requirements.

  • Encode in stereo or mono with bitrates up to 320 kbps.

  • Record while streaming

  • Pearl is capable of recording the streaming output as well as automatically uploading the recordings to your CMS.

  • Records the stream in the same layout as it is streamed (for example a multi-source layout) as well as records each source separately for post-production flexibility.

  • Stores the video files to a hard drive, with 1 TB of storage (equivalent to almost 300 hours of recordings at HD resolutions), in AVI, MP4, MPEG-TS or MOV format (common and easy to use formats).

  • Admin interface indicates the amount of free storage space.

  • Manage the size of your recorded video files by configuring Pearl to start a new file based on a time or file-size limit. When the limit is reached, the current recorded file is closed and available for download while a new file is opened for continued recording – all without missing a frame.

Easy access to external file storage

Pearl offers a variety of options for storing your recorded files:

  • Access files quickly at Gigabit Ethernet speeds.

  • Store the files on the device itself, this is useful when you don’t have access to a network or an external device. You can always download the files later.

  • You can transfer the recorded files to an external USB storage device or local network storage via SFTP, SCP, FTP, RSYNC, or CIFS to ensure you don’t run out of disk space on your device and facilitate 24/7 recording.

  • Configure automatic file transfer when a USB device is inserted.

  • Integrate easily with commercial content management systems.
