Extron SMP 401 12G-SDI 4K/60 Multi-Recording and Streaming w/12G-SDI

The SMP 401 12G-SDI 4K/60 Multi-Recording and Streaming w/12G-SDI is a high-performance all-in-one 4K/60 recording and streaming processor that easily captures, switches, scales and distributes AV sources and presentations. Powerful processing with H.264/H.265 encoding provides up to five recordings and six streams concurrently. The SMP 401 captures a variety of sources from three HDMI inputs, two RTP/RTSP virtual inputs, and an optional 12G-SDI input. Additionally, the SMP 401 audio DSP provides independent audio mixing per channel and supports line or microphone level audio, with available +48V phantom power. The user-friendly front panel LCD screen enables video preview for confidence monitoring, and simple menu navigation for easy configuration. The SMP 401 is a robust solution for any environment that requires multiple high-quality recordings and live streams.

Flexible Signal Support

The SMP 401 12G-SDI 4K/60 Multi-Recording and Streaming w/12G-SDI processes two high resolution AV sources from up to four available local input signals:

• One of two HDMI signals can be selected from Channel A along with analog line level or HDMI-embedded stereo audio.
• One HDMI or optional 12G-SDI signal can be selected from Channel B along with analog line level or microphone level audio or HDMI-embedded stereo audio.

The SMP 401 also supports up to two independent RTP/RTSP push/pull streams as additional virtual input signals from network streaming sources such as IP cameras and other encoded sources. All inputs support common video formats from 640x480 to 4096x2160.

Customized Recordings and Streams

The SMP 401 can capture up to four video sources to produce multiple recordings and streams. From local sources it produces full screen views or any two-window layouts; one local source captured from Channel A and one from Channel B. Additionally, up to two independent virtual inputs can be captured and output as full screen recordings and streams.

The SMP 401 processing allows flexible configuration of different encoders with a total capacity of 4K/60. Up to three Archive encoders are used for recordings and streams and one Confidence encoder for streaming only.

The following images show examples of the number of recordings and streams possible with encoders configured at different resolution outputs. All encoders can be configured in any of the options below, including composite view Channel A + Channel B, full screen Channel A, or full screen Channel B.

Enhanced DSP with Independent Audio Mixing

The SMP 401 audio DSP features enable customized AV content with independent audio signals per encoder. Users can choose their audio source from either analog or digital audio captured on Channel A, Channel B, or a blend of signals from both channels. Audio output signals are adjusted automatically during source switches to eliminate potential clicks, pops, or undesired effects, producing a quality audio experience without the need for external processing equipment.

Effective Multi-Window Processing

The SMP 401 offers highly flexible source presentation options. The Channel A and Channel B local input signals can be presented individually at full screen or combined in any two-window display arrangement. Up to sixteen customized window presets can be prepared, mixing the inputs with a PNG background image, logo, and metadata. These flexible, multi-source processing features make it easy to recreate the live presentation experience. They also provide viewers with greater insight into the event’s context, facilitating interpretation and retention of the information presented.

Independent Video Encoding

The powerful processing of the SMP 401 enables the use of independent H.264 and H.265 video codecs per encoder. H.265 offers high quality video at lower size files for optimized storage and less bandwidth. H.264 is a widely supported codec used by many third-party video platforms. The ability to select different video encoding provides users with flexibility, optimization opportunities, and compatibility assurance, leading to improved performance, quality, efficiency, and future-proofing of video workflows.

AV Recording with Enhanced Data

The SMP 401 produces an MP4 (M4V) container format, which is compatible with virtually any media player. It records at up to 4K/60 resolutions, supporting a variety of quality, storage, and playback requirements. Recordings can include metadata with information such as: Title, Creator, Subject, Description, Publisher, Contributor, and Date, which makes searching, indexing, and managing multiple recordings more efficient. Set chapter marks during recording sessions for highly efficient searching and scanning during file playback. JPEG thumbnail images are captured periodically and for specially marked events. Thumbnail image size is selectable to meet the needs of the recording environment.

Storage

MP4 recordings can be saved to internal solid-state storage, a USB storage device, or a defined network storage directory. USB storage devices connect easily to the SMP 401 from the front or rear panel USB ports at write speeds up to 5 Gbps. The SMP 401 internal SSD is used for internal recordings, video bit rates can be adjusted from 200 Kbps to 200 Mbps and audio bit rates from 64 Kbps to 384 Kbps. The approximate capacity in hours for a 32 GB thumb drive, the SMP 401 internal solid-state storage and a 1 TB network drive is presented in the table below. Hours of storage capacity are calculated for video bit rates from 1 Mbps to 220 Mbps plus 192 kbps for audio.

Extensive Streaming Capabilities

The SMP 401 offers extensive streaming capabilities at different bit rates and resolutions from 640x480 up to 4K/60. High resolution, high bit rates can be used to deliver superior quality, presenting video on large screens in overflow applications, while a lower bit rate and resolution can be used for streaming distribution or confidence viewing applications. Streaming bit rates can range from 200 kbps to 200 Mbps for video and 64 kbps to 384 kbps for audio. Both push and pull streaming sessions are supported, offering a range of streaming transport protocols and session management methods. This range of capabilities provides the flexibility to stream from the SMP 401 to a variety of devices in different system configurations and network conditions. Stream to popular third-party platforms such as YouTube, Facebook Live, Twitch, and Wowza and supported education content management platforms.

Simple Network Management Protocol - SNMP traps, email and Simple Mail Transfer Protocol - SMTP can be used to deliver messages to AV and IT support staff or monitoring systems when signal errors or encrypted sources are detected and when storage is near capacity, allowing proactive service to be initiated. Operational system data is logged continually, identifying recording sessions, storage directory use, file names, metadata, and storage capacity. This information provides valuable data for evaluating usage patterns and operating concerns.

Signal Processing Simplifies Source Management

Like many other Extron AV products, the SMP 401 offers comprehensive digital and analog signal processing features that make interfacing presentation sources easy. EDID Minder® automatically manages EDID communications to ensure sources power up properly and a reliable output signal is provided. Intelligent HDCP-compliant signal management passes encrypted signals to HDCP-compliant connected displays, while presenting a green or black screen with HDCP message on encoded media sent to non-compliant displays. All signal switching produces clean transitions, with no distracting visual jumps, glitches, or distortion that would distract from recordings and live streaming. Auto-Image™ automatically adjusts source sizing, centering, and filtering and Auto Input Memory saves the size, position, and picture settings of incoming signals, ensuring that sources present properly. Comprehensive picture controls and aspect ratio controls produce quality and accuracy for every application.
