Method for testing in-vehicle radio broadcast receiver device

The method includes splitting a radio signal received at an in-vehicle antenna into two RF streams, and at the device under test, converting the first RF stream into a demodulated audio signal and transmitting it to the tester and recorder device. The tester and recorder device also receives the demodulated audio signal, determines a spectrum of frequencies over time, inputs the spectrum of frequencies into an artificial intelligence (AI) module of audio abnormality detection. The device also receives the second RF stream, converts it into a data signal, and records the data signal into a temporary storage memory. Then, when the AI module outputs of a positive detection of audio abnormality, the device transfers data from the temporary storage memory into a permanent storage memory, where the transferred data corresponds to a time window including the detected audio abnormality.

Audio Playback Management of Multiple Concurrent Connections
20220103199 · 2022-03-31 ·

Examples described herein relate to management of concurrent audio streams from different sources. Portable playback devices, such as wearable wireless headphones and earbuds, as well as portable battery-powered speakers, may include multiple network interfaces for connection to different types of networks, such as an 802.11-compatible network interface for connection to wireless local area networks (e.g., Wi-Fi® networks) and an 802.15-compatible network interface for connection to a mobile device via a personal area network (Bluetooth®). Via such connections, the playback devices may receive two or more concurrent streams. By managing these streams according to playback policies, the portable playback devices may play the user's intended audio without necessarily requiring user input to explicitly select among the concurrent streams.
