Portable HD/SD Transmitter Integrated Encoder and Multi-Mode Modulator
The ChannelMaster is a totally integrated, feature-rich portable microwave transmitter offering MPEG-4 HD/SD encoding. The ChannelMaster is available in single, dual or tri-band configurations, using frequency bands from 1.5-15.4 GHz. The ChannelMaster encoder features adjustable long GOP encoding including I P and B frames improving video quality as well as a low delay mode. The encoder can be purchased as HD/SD or SD only. For increased flexibility a wide array of inputs are provided, including composite video/audio, SDI (with de-embedded audio), ASI and 70 MHz.
The ASI input is ideal for use with an external encoder or to support digital repeater applications. Two audio inputs are standard, while four audio inputs are available. For FM operation, an internal SDI to composite converter is integrated providing seamless operation between analog and digital modes. This eliminates the need for an external converter when used in an SDI plant. This feature also de-embeds the audios if desired. The ChannelMaster features software generated modulation formats that are stored in circuit board PROMs (programmable read only memory). Available formats include — FM (NTSC/PAL), COFDM, VSB, DVB-S and single carrier QAM. As additional digital software formats become available, the PROMs can be easily updated. This feature increases the flexibility of the ChannelMaster and helps avoid obsolescence.
The ChannelMaster is equipped with a front panel smart display, five quick keys, and 15 quick-store presets for quick set up and operator convenience. The ChannelMaster Transmitter uses a rugged and weather resistant clam shell design and is very lightweight, optimizing it for a multitude of applications. It can also be purchased in a “two box” configuration for OB vehicles.
