Matrox has been a leader in computer video card technology for years. Matrox Max technology is continuing that legacy with H.264 encoding, decoding, and acceleration, and it is available on the Matrox CompressHD accelerator card and the Matrox MXO2 family of cards for PC and Mac. A vast array of tuneable controls for the H.264 encoding, such as speed, video quality, and noise filtering, make the technology extremely useful for video content publishers.
Mediasite, from Sonic Foundry, has been popular for years in colleges and corporate training environments because of its ability to synchronize a computer presentation with a camera and audio. Sonic Foundry describes its product offering for these systems in four parts: record, deliver, watch, and manage.
The Mediasite Recorder records in realtime and may be scheduled to automatically stop and start, and those presentations may be streamed live or viewed on demand. Next in line is the Mediasite EX Server, a powerful platform for delivering and managing the multimedia presentations from the recorder. It has the ability to schedule, secure, catalog, customize, integrate, and track recorded content. The latest changes to the “watch” part of the line include a reworking of the Mediasite Player, which now enables the viewer to customize their experience for more of a context-based viewing. Mediasite Catalog automatically publishes your recorded presentations to designated online catalogs for immediate viewing. Mediasite's Scheduler allows you to designate recording dates and times, manage recurring presentations, and email event notifications.
Streambox employs a similar approach to IP streaming as some of its close competitors, that of providing solutions for every part of the process. For encoding, the company offers Avenir, a new battery-powered mobile encoder that is able to encode HD/SD video and transmit over 3G and 4G cellular networks, making it a hot commodity for newsgathering, live sports, and emergency response. For SD encoding, the SBT3-2300 and SBT3-5300 offer features such as low end-to-end latency and advanced forward error correction. The SBT3-9300 allows for HD and SD video input with excellent video quality (HD from 512kbps to 30Mbps), as well as simultaneous output of HD and downconverted SD video from a single HD source. Also available are software encoders for Mac laptops.
The Distribution Server allows routing streams from multiple encoders to multiple decoders and locations, and the Broadcast Server works as a point-to-multipoint stream router, making it ideal for streaming to laptop and desktop clients.
