abstract:A control track is a track that runs along an outside edge of a standard analog videotape (including VHS). The control track encodes a series of pulses, each pulse corresponding to the beginning of each frame.
All relevant functions including looping, cueing, effects control and track browsing are immediately accessible on the robust and portable hardware, while dynamic multi-color backlighting, LED status displays and comprehensive level metering allow DJs to focus on their performance rather than on the computer screen.
Bluetooth head units from Sony support a complete music streaming experience, allowing wireless playback, trackcontrol, and display of song information from Bluetooth enabled MP3 players or smartphones.
Another recent innovation could also help: watershed management, which means managing water supplies across political or management borders can better control pollution and track water withdrawals.
