Video alternate network access points and receivers
Concepts and technologies for video alternate network access points and receivers that enable wireless delivery of video content to multiple customer premises over a service area are provided herein. In an embodiment, a system includes a satellite dish receiver that is configured to receive a satellite video feed, and a video alternate network access point that is communicatively coupled to the satellite dish receiver. The video alternate network access point can perform operations that ingest the satellite video feed directly from the satellite dish receiver. The operations can activate a microcell transceiver embedded within the video alternate network access point, and identify a multicast-broadcast single-frequency network channel. The operations can then transmit, to a video alternate network receiver device from the microcell transceiver, the satellite video feed over at least the multicast-broadcast single-frequency network channel.

Time-alignment measurement for hybrid HD 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.

Time-alignment measurement for hybrid HD radio™ technology
A method for processing a digital audio broadcast signal in a radio receiver, includes: receiving a hybrid broadcast signal; demodulating the hybrid broadcast signal to produce an analog audio stream and a digital audio stream; and using a normalized cross-correlation of envelopes of the analog audio stream and the digital audio stream to measure a time offset between the analog audio stream and the digital audio stream. The time offset can be used to align the analog audio stream and the digital audio stream for subsequent blending of an output of the radio receiver from the analog audio stream to the digital audio stream or from the digital audio stream to the analog audio stream.
