TIME-ALIGNMENT MEASURMENT FOR HYBRID HD TM RADIO TECHNOLOGY
A method for processing audio signals in a radio transmitter, includes: receiving an analog audio sample stream and a digital audio sample stream; determining offsets in time between the analog audio stream and the digital audio stream using a normalized cross-correlation of audio envelopes of the analog audio sample stream and the digital audio sample stream; filtering the determined offsets in time to produce filtered offset values; determining an alignment slip adjustment value as a function of the filtered offset values; aligning the analog audio sample stream and the digital audio sample stream using the determined alignment slip adjustment value; and generating a hybrid radio signal for broadcast that includes time-aligned analog audio and digital audio.

Systems and methods for providing an in-vehicle image supplement
Systems and methods for providing an in-vehicle image supplement are disclosed. One embodiment includes receiving a broadcast media signal that includes a content portion and a metadata portion, determining whether a primary image is included in the metadata portion, and in response to determining that the primary image is included in the metadata portion, providing the primary image for display. Additionally, in response to determining that the primary image is not included in the metadata portion, some embodiments include determining whether the primary image is otherwise available and in response to determining that the primary image is otherwise available, retrieving the primary image and providing the primary image for display. In response to determining that the primary image is not otherwise available, some embodiments include determining whether a secondary image is available, retrieving the secondary image, and providing the secondary image for display.
