Eye-to-Eye V i d e o o v e r by David Kirk L ive video streaming via Internet Protocol is perhaps most familiar in the form of Skype’s free-of-charge online videophone service. Skype is a very easy way for an on-location broadcaster to get a video contribution back to base. A safer and more conventional technique, as with a reporter- to-anchor interview, is to live-stream video via one’s own IP encoder straight into the studio for immediate viewing over a terrestrial and/or satellite network. If time is not so critical, the story can simply be emailed as a file straight out of the reporter’s camcorder.  Live streaming via IP also offers the option of one-to-many near- live content distribution if speed happens to be a vital issue. This is a big subject, encapsulated here into a summary of the latest equipment on offer from the major suppliers. I P Ateme’s CM4101 IP encoder is intended for use in contribution and distribution. It can be upgraded from SD to HD, in MPEG-2 or MPEG-4, 4:2:0 8-bit up to 4:2:2 10-bit. It is also capable of streaming AVC-I frame only MPEG-4 up to 150 megabits per second. From the same company, the DR8400 is an integrated receiver/ decoder designed for high quality contribution. It has a double built-in Digital Rapids’ new carrier- grade StreamZ Live Broadcast hybrid live encoder can perform simultaneous H.264 or MPEG-2 encoding for traditional television applications. It can also handle and multi-format encoding (including adaptive bit rate streaming) for any-screen delivery to devices such as mobile phones, tablets and personal computers, all in a single encoder. Envivio’s 4Caster C4 Gen 3 encoder/transcoder is designed to produce live video streams for mobile television, online television and Internet Protocol television from a single platform.  It incorporates an Intel Xeon Processor 5600 Series and is firmware-upgradeable to support future formats including 1080p 3D. 38 | TV-BAY MAGAZINE DVB-S/S2 demodulator, IP Gigabit and ASI with a transport stream speed of up to 200 megabits per second. Decoding speed is up to 80 megabits per second. The DR8400 is also capable of decoding AVC-I frame streams of up to 150 megabits per second. It includes full front panel control and an unique and a browser- based user interface with monitoring features. Blackmagic Design’s ATEM Television Studio allows live production and simultaneous generation of H.264 files for the web. Suggested applications include local government meetings, school productions and community events. The basic ATEM switcher is a chassis with a software-based control panel plus the option of hardware control. Blackmagic also offers DeckLink cards which can be used for streaming when combined with compatible software such as Adobe Flash Media Encoder. Teracue’s ENC-300-DVI-Portable is is intended primarily for digital signage streaming. An integral H.264 SD/HD video encoder processes DVI with analogue audio. It also handles HDMI with embedded audio signals at up to 1920 x 1080 pixels resolution. Special DVI formats, such as 1600 by 1200 or 1920 x 1200, can also be processed. >>
