Media delivery platform
A method of delivering an audio and/or visual media file including, for example, one or more of full or partial master recordings of songs, musical compositions, ringtones, videos, films, television shows, personal recordings, animation and combinations thereof, over the air wirelessly, from one or more servers to an electronic device with or without an Internet connection, said method comprising transmitting and audio and/or visual media file in compressed format to said electronic device, and wherein the electronic device is effective to receive said audio and/or visual file and playback said audio and/or visual content on demand by a user.
1. A digital media communication system, the system comprising:
a server operably coupled to a database, the database including a plurality of digital media files, said server including a server digital signal processor and memory,
wherein the server digital signal processor is configured to,
receive a non-optimized digital media file,
optionally store the non-optimized digital media file in the database,
optimize the non-optimized digital media file according to an optimization scheme,
store the optimized digital media file in the database,
receive a request for the digital media file, and
cause a transmission of the requested optimized digital media file by synchronized orthogonal frequency-division multiplex modulation to a wireless electronic device, said device including a device digital signal processor configured to receive and process the optimized digital media file sent by synchronized orthogonal frequency-division multiplex modulation.
2. The system of claim 1 , wherein the optimization scheme comprises:
normalizing an amplitude of the digital media file;
performing a pre-emphasis filtering on the normalized digital media file; and
re-normalizing the pre-emphasis-filtered and normalized digital media file.
3. The system of claim 1 , wherein the optimization scheme comprises:
converting the digital media file to mono by summing of a left channel and a right channel if the digital media file is stereo and the received request for the digital media file is only for mono playback;
normalizing an amplitude of the digital media file;
converting the digital media file according to a sampling frequency;
performing a pre-emphasis filtering on the digital media file;
re-normalizing the digital media file; and
compressing the digital media file according to a compression scheme.
4. The system of claim 1 , further comprising a graphical user interface configured to provide graphical access to the digital media file.
5. The system of claim 4 , wherein the graphical user interface provides an identifying icon for the digital media file.
6. The system of claim 4 , wherein the request for the digital media file is received by selection of the identifying icon by the wireless electronic device.
7. The system of claim 1 , wherein the non-optimized digital media file is received from the wireless electronic device.
8. The system of claim 1 , wherein the request for the digital media file is received from the wireless electronic device.
9. A system for communicating content-rich digital media files to a wireless telephone having a digital signal processor, the system comprising:
a database configured to store a plurality of content-rich digital media files; and
a server operably coupled to the database and including a server digital signal processor and memory, the server digital signal processor configured to,
optimize the non-optimized digital media file according to an optimization scheme,
store the optimized digital media file in the database,
receive a request from the wireless telephone, the request identifying at least one of the plurality of content-rich digital media files, and
cause to transmit to the wireless telephone over a cellular data channel by orthogonal frequency-division multiplex (OFDM) modulation the identified at least one of the plurality of content-rich digital media files
wherein the wireless telephone is configured to receive and process OFDM transmitted content-rich digital media files.
10. The system of claim 9 , wherein the server and the wireless telephone are further operably coupled by a WI-FI data channel.
11. The system of claim 10 , wherein the WI-FI data channel utilizes orthogonal frequency-division multiplex (OFDM) modulation.
