A media source device includes media files in either original source format or in alternative digital formats, based on a content descriptor indicated by a client device from a plurality of content descriptors generated to represent possible transcodings of the source format. In the alternative, a media source device can receive a client device report and subsequent request for a media file. The media source device can send the media file to the client device in a particular digital format based on whether the content descriptor corresponding to the media file is compatible or incompatible with the client device. The bit rate used to send the media file to the client device can be adjusted based on the available transmit bit rate.

Media source device with digital format conversion and methods for use therewith

A multimedia server includes a first transceiver that modulates a data signal to produce a first radio frequency (RF) signal and that transmits the first RF signal to a client over a first transceiver channel when the first transceiver is in a transceive mode. The first transceiver includes a first channel control that performs a first channel scan when the first transceiver is in a scan mode, that determines at least one performance parameter of the first transceiver channel and asserts a low performance signal when the at least one performance parameter compares unfavorably to a performance threshold, and that switches the first transceiver to a selected alternative transceiver channel when the low performance signal is asserted.

Multimedia server with channel control and methods for use therewith

A circuit for use in a multimedia server module that is coupleable to a plurality of multimedia sources that produce at least one multimedia signal and that can transmit over a wireless communication path to at least one client module, the circuit includes an encoder module that encodes the at least one multimedia signal to produce an encoded signal. An RF server transceiver module produces a channel signal that includes the encoded signal, and that wirelessly transmits the channel signal at a link data rate over the wireless communication path, the RF server transceiver module including a first monitor module that generates first RF performance signals that are based on the performance of the wireless communication path, and a quality of service module that receives the first RF performance signals and adjusts both a range of the link data rate and the link data rate.

Multimedia client/server system with adjustable data link rate and range and methods for use therewith

An encoded signal is modulated to produce a first radio frequency (RF) signal that is transmitted to a client module over a first transceiver channel when a first transceiver module is in a transceive mode. A channel scan is performed when the first transceiver module is in a scan mode. The encoded signal is modulated to produce a second RF signal and that is transmitted over a second transceiver channel when a second transceiver module is in a transceive mode.

Client module, multimedia server and methods for use therewith

A circuit for use in a multimedia server module includes an encoder module that encodes a multimedia signal to produce an encoded signal that includes a sequence of packets having a packet size. An RF server transceiver module, coupled to the encoder module, that produces a channel signal that includes the encoded signal, and that wirelessly transmits the channel signal at a link data rate over a wireless communication path to at least one client module The RF server transceiver module includes a quality of service module that adjusts the packet size based on first RF performance signals determined by the RF transceiver, based on second performance signals received from a client module and/or based on adjustments made to the link data rate.
