With digital broadcast systems such as Digital Audio Broadcast (EUREKA
147 DAB), MPEG Layer-2 is used in many countries all over the world.
As for any broadcast system, channel capacity is a crucial issue
for commercial success. The income revenue of a given system is
directly connected to the amount of services it contains. The higher
the number of services, the more attractive it is for broadcasters
and recipients. In most cases, the overall system capacity is fixed,
so there is no chance to extend the number of transmission channels
easily.
This is exactly where SBR comes into play. By adding SBR to MPEG
Layer-2, the bit rate of a particular audio service can be reduced
up to 50 % by maintaining the audio quality. Thus, the amount of
services in a certain system can be increased by remaining backward
compatibility to MPEG Layer-2 decoders - non-SBR receivers may stay
in use!
Features
• Transparent use in MPEG Layer-2 systems
• Doubles the amount of audio programs in a given digital
broadcast system
• CD-quality stereo at 112 kbps
• High Quality at 96 kbps
• Fully compatible with MPEG Layer-2
• Wider frequency bandwidth
Availability
Decoders: Win32 and Linux
Encoders: Win32 and Linux
Furthermore,
highly optimized MPEG Layer-2 encoder implementations are available
for Win32, Linux, and Motorola 56xx DSPs.
