HD/SD ENG/SNG/OB Van Transmitter
The Newscaster VT7 is the "Broadcasters Best Choice" for the migration to HD ENG. The VT7 is a major step forward in van transmitter technology and offers more useful features than any other product in its class. The VT7 is a two box design and can be configured for both analog and digital operation. The digital engine is comprised of a HD/SD encoder with adjustable long GOP encoding featuring I, P and B frames as well as a low delay mode. The COFDM modulator has full control over the modulation formats, bandwidth, data rate and guard interval. For increased flexibility a wide array of inputs are provided, including: video/audio, SDI (HD) with embedded audio, ASI and 70 MHz. The ASI input is ideal for use with an external MPEG2 encoder or repeater applications. Two audio inputs are provided standard, while four audios are available.
The VT7 features software generated modulation formats that are stored in onboard, circuit board PROMs. Available formats include; FM (NTSC/ PAL), COFDM, VSB, single carrier QAM and DVB-S. As additional digital software formats become available, the software can be easily updated, increasing the flexibility of the VT7 and avoiding obsolescence. Software based modulation greatly reduces system complexity and component heat generation, thus providing greater flexibility and higher reliability.
