Problems solved by technology

However, two multi-channel signals (e.g. a Digital Audio Broadcasting (DAB) stereo signal and an FM stereo signal) can have different stereo information due to processing that has been performed as a result of poor reception quality

Abstract

Embodiments of systems and methods for blending multi-channel signals are described. In one embodiment, a method for blending multi-channel signals involves computing component signals from the multi-channel signals, cross-fading the component signals based on different temporal rates to generate cross-faded component signals and generating a blended multi-channel signal based on the cross-faded component signals. Other embodiments are also described.

Description

Technical field [0001] The embodiments of the present invention generally relate to signal processing systems and methods, and more specifically, to systems and methods for processing multi-channel signals. Background technique [0002] The digital transmission system can be used to replace the traditional analog transmission system. For example, in digital radio broadcasting, the signal is encoded in the digital domain, which is the opposite of traditional analog broadcasting using amplitude modulation (AM) or frequency modulation (FM) systems. The received and decoded digital audio signal has many advantages compared to its corresponding analog audio signal, such as better sound quality, and better robustness to radio interference (multipath interference, co-channel noise, etc.) ). [0003] However, some digital transmission systems are used in combination with analog transmission systems. For example, many radio stations that transmit digital radio also transmit the same prog...
