Dual Recording H.264 Streaming Media Processor

The SMP 352 is a high performance recording and streaming processor for capturing and distributing AV sources and presentations as recorded media or live streaming. It can create independent recordings from two different sources, and incorporates Extron’s FlexOS, a flexible platform for automating system operation. The SMP 352 accepts HDMI, component, composite, and optional 3G-SDI signals and applies two-window processing to selected sources. It can record and stream simultaneously and can stream at two different resolutions and bit rates concurrently using a range of transport protocols and session management options. With no recuring licensing fees and comprehensive control and configuration features, the SMP 352 is a cost-effective, integration-friendly solution for delivering presentations to a larger audience.

The SMP 352 dual recording feature creates independent recordings from two different video sources with independent archive stream settings for each channel. Users can choose to create a single layout for simultaneous recording and streaming, or create synchronized recordings and streams of two video channels with the dual recording feature. A confidence stream provides a composite of two video sources to monitor both channels from a single stream. The SMP 352 also has advanced audio DSP features for level control, filtering, and dynamics, as well as streaming presets that increase functionality and provide a simplified workflow.

Flexible Signal Support
The SMP 352 processes two high resolution AV sources from up to five available connections. One of two HDMI signals can be selected from Channel A along with analog or HDMI-embedded stereo audio. Channel A also provides a loop through HDMI and audio connection, which can be passed directly to a presentation display. Channel B inputs support common camera formats including composite, component HD, and HDMI. A second model, the SMP 352 3G‑SDI, accepts serial digital video signals supplied by cameras and other professional video sources. The Channel A and B input connections both support computer-video formats from 640x480 to 1920x1200, and video formats from 480p to 1080p/60. They can be switched live during a presentation.

Effective Multi-Window Processing
The SMP 352 offers highly flexible source presentation options. The Channel A and B input signals can be presented on the output individually at full screen or together in any two-window display arrangement including side-by-side. Up to sixteen customized window presets can be prepared, combining the Channel A and B inputs with a PNG background image and metadata. These flexible, multi-source processing features makes 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.

AV Recording with Enhanced Data
The SMP 352 produces an MP4 (M4V) container format, which is compatible with virtually any media player. It records at 480p, 720p, or 1080p 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 in order to meet the needs of the recording environment.

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 352 from the front or rear panel. The approximate capacity in hours for a 32 GB thumb drive, the SMP 352 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 10 Mbps plus 192 kbps for audio.
