FLOW SYNCHRONIZATION IN A RECEIVER
20200177293 · 2020-06-04 ·

A method for synchronizing a first data stream and a second data stream, at least one stream among the first stream and second stream being received by radiofrequency broadcasting and the other stream being received via an IP network, the first and second streams carrying the same service. The method involves receiving a value of the mean offset between the first stream and the second stream; storing the first stream in a first buffer and storing the second stream in a second buffer; extracting a first extract from the first buffer and a second extract from the second buffer, according to the mean offset value received; comparatively analyzing the first extract and the second extract in order to deduce a value of the actual offset between the first stream and the second stream; synchronizing the first stream and second stream according to the actual offset value obtained.

10638188 · 2020-04-28 · ·

A radio signal processing circuit comprises multiple audio blend channels, an audio decoder, a program selector and a blending circuit. The audio blend channels are configured to receive digital audio packets for multiple supplemental audio programs. Each audio blend channel includes an audio blend buffer and a signal quality metric circuit. The signal quality metric (SQM) circuit configured to determines an audio quality indicator for the digital audio packets of the program and indicates availability of the program according to the audio quality indicator regardless of whether the program is selected for play. The program selector configured to provides digital audio packets from a selected audio blend channel to the audio decoder to produce a digital audio signal. The blending circuit blends the digital audio signal produced for the selected audio blend channel with a signal representing silence according to the audio quality indicator for the audio blend channel.
