1. (method—
- best audio file) A method of selecting a preferred audio recording of a discrete radio transmission, comprising the steps of;
receiving, by plural radio terminals, a discrete transmission of audio content from a radio channel having a channel identity;
recording, and storing at a network address, an audio file of the discrete transmission, correspondingly, by each of the plural radio terminals;
sending a transmission report that includes the channel identity, a transmission time, and the network address, correspondingly, from each of the plural radio terminals to a channel manager;
selecting, by the channel manager, a preferred audio file of the discrete radio transmission by comparing the contents of transmission reports sent from the plural radio terminals, andcommunicating the network address of the preferred audio file to a network destination.

Abstract
A network based system for distributing audio recordings of discrete transmissions from land mobile radio systems received by plural radio terminals having scanning receivers to plural client terminals, including methods of selecting the best available recordings and selectively storing content both locally in the radio terminals and at network based storage locations.

cascade server) A method of selecting audio recordings of radio transmissions for static network storage, comprising the steps of;receiving an intermittent series of discrete transmissions of audio content from a radio channel having a channel identity, by a radio terminal having a terminal identity, which includes a radio receiver, a memory, and a network file server; recording, and storing in the memory of the radio terminal at a location identified by a first network address, a first audio file of a first discrete radio transmission; sending a transmission report by the radio terminal corresponding to the first audio file, which includes the channel identity, the terminal identity, and the first network address, to a cascade server located on the network; querying a subscription database, by the cascade server, for a list of plural client terminals subscribed to receive transmission reports according to the channel identity, and then forwarding at least a portion of the transmission report to the plural client terminals, thereby enabling the plural client terminals for selectively requesting a copy of the first audio file from the network file server of the radio terminal according to the first network address; if the list comprises a quantity of plural client terminals greater than a predetermined value, sending an upload command, including the channel identity, to the radio terminal; in response to receipt of the upload command by the radio terminal, annotating the channel identity for static network storage, then recording a subsequent audio file of a subsequent discrete radio transmission by the radio terminal, and uploading the subsequent audio file to a predetermined address in a static network server, and sending a subsequent transmission report to the cascade server, which includes the channel identity and the subsequent network address, thereby enabling the cascade server to forward the subsequent transmission report to the plural radio terminals. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. (scanner) A radio terminal apparatus for scanning and recording audio files of discrete radio transmissions, and for reporting and serving corresponding audio files into a network to an external network terminal, said apparatus comprising:
-
a frequency agile radio receiver that selectively tunes plural channels according to plural channel identities stored in a channel memory, so as to receive series of discrete transmissions of audio content; a squelch circuit that detects a discrete radio transmission of audio content by the detection of a start and an end of said discrete radio transmission; a processor coupled to selectively tune said frequency agile radio receiver and monitor said squelch circuit, and wherein said processor records, and stores in a memory at a location identified by a network address, an audio file of said discrete radio transmission, and said processor generates a corresponding transmission report of said discrete radio transmissions, which includes said channel identity, a transmission time, and said network address at which the corresponding audio content is stored; a network interface coupled to said processor; a network file server coupled to said processor, and wherein said processor communicates said transmission report through said network interface to the external network terminal, thereby enabling the selection and request for audio content though the network from said network file server according to said network address in said transmission report, and wherein said network file server is responsive to a request for audio content received through the network to recall an audio file from said memory according to a specified network address, and upload said audio file into the network. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
