Embodiment Construction

[0030] See attached picture, figure 1 is a functional block diagram of the relevant components of the studio site 10, FM transmitter site 12 and studio-transmitter link (STL) 14 that may be used to broadcast the FM IBOC DAB signal. The studio site includes, among other things, studio automation equipment 34, an overall operations center (EOC) 16, which includes an input 18, an output 20, and a studio-transmitter link (STL) transmitter 48. and exciter auxiliary service unit (EASU) unit 22. The transmitter site includes an STL receiver 54 , a digital exciter 56 including an exgine subsystem 58 and an analog exciter 60 . Although in figure 1 In , the outputter is present at the radio station's studio location and the exciter is at the launch site, although these elements can be co-located at the launch site.

[0031] At the studio location, the studio automation equipment supplies the EASU with Main Program Service (MPS) audio 42, MPS data 40 to the exporter, Supplementary P...

Abstract

An apparatus includes a network receiver for receiving an over-the-air in-band on-channel broadcast signal and extracting broadcast content from the broadcast signal, and an output for delivering the content by way of a first receiver output signal to a plurality of network player devices. A method performed by the apparatus is also included.

Description

technical field [0001] The present invention relates to radio reception methods and devices, and more particularly to methods and devices for distributing In-Band On-Channel (IBOC) Digital Audio Broadcasting (DAB) radio signals. Background technique [0002] IBOC DAB radio technology provides digital audio and data services from terrestrial transmitters to mobile, portable and fixed receivers in the existing medium frequency (MF) and very high frequency (VHF) radio frequency bands. The IBOC DAB signal may be transmitted in a hybrid format comprising an analog modulated carrier combined with multiple digitally modulated carriers, or in an all digital format in which no analog modulated carrier is used. By using hybrid mode, a broadcaster can continue to transmit analog AM and FM simultaneously with a higher quality, more robust digital signal, allowing itself and its listeners to switch from analog to digital radio while maintaining its current frequency distribute.
