发明名称 WIRELESS SOUND TRANSMISSION AND METHOD
摘要 A system for providing sound to at least one user has at least one audio signal source, a transmission unit with a digital transmitter audio data packets from the audio signal source via a wireless digital audio link; at least one receiver unit having at least one digital receiver; and a hearing stimulator responsive to audio signals from the receiver unit. The transmission unit encodes the audio signal as audio data blocks distributed onto at least two audio data packets, one of which is a low-quality packet, and one of which is a high quality packet only a low-quality version of the audio signal being retrievable from the low-quality packets, and a high-quality version of the audio signal being retrievable from both the low-quality packets and the high-quality packets. The low-quality packets and the high-quality packets are transmitted in respective dedicated slots of a multiple access protocol frame.
