Taking the most recent loudness research into account, DB8 ensures consistency across programs without the need for previewing or a priori measuring of level.
DB8 offers simultaneous Realtime Loudness Control, Multiband Processing, Format Conversion, Limiting and on-line Delay. All processing and I/O is done at state-of-the-art resolution and attention to detail, ensuring that DB8 is the strongest link of a broadcast or linking chain.
DB8 contains 4 separate processors, each capable of dealing with Mono, Stereo, LtRt or 5.1 signals. For example, one DB8 can process 8 different mono, 4 different stereo, or a combination of mono, stereo and 5.1 signals.
DB8 can serve analog and digital transmission simultaneously, while allowing the station to examine how new possibilities of digital TV are best used in a certain geographical area, or for a certain type of program.
Many DB8 units can be controlled from the same (Ethernet) network, and the vast processing pool available in each unit may be updated in the field to take advantage of new possibilities, or to comply with changing demands of the broadcast industry going through the analog to digital transition. Main Features DB-8 TV Transmission Features Keep production simple and fast using the unique stereo up-convert facility of DB-8. Disable up-conversion when transmitting 5.1 feature films,leaving only loudness control and limiting in the signal path.The 48 bit processing of DB8 ensures pristine audio quality under all conditions.
Loudness Control Inconsistent audio levels are the number one source of viewer irritations. The true loudness leveling tools provided in the DB-8 take care of these complaints. No more loud commercials, but a consistent audio level true to the viewers perception will satisfy the high demands of today’s viewer.
Peak Control Intersample accurate limiting allows very tight peak control and maximum audio quality from lossy compression codecs. Distortion canceling limiting techniques keep distortion to an absolute minimum allowing the DB-8 to deliver clean crisp audio.
