Definitions

  • This invention relates generally to a system and method for permitting a particular piece of audio data being broadcast to be recorded and compressed at any time during the broadcast of that particular piece of audio data.
  • the invention is directed to a technique for, while listening to an audio device, being able to download and compress any piece of audible content, such as the currently played song, to a local memory even if the song is partially completed.
  • the technique begins storing each song in a buffer as the song starts. Then, at any time during the song, the user may elect to download the song since the song is stored in the buffer. The buffer may be refreshed at the beginning of each song.
  • a method for recording music being played by an audio device includes the steps of storing data corresponding to the music currently being heard from the audio device by a user into a buffer wherein the buffer records the music starting at the beginning of each song and receiving user input at any time during the playing of the song indicating that the song is to be recorded.
  • the song may then be downloaded based on the user input, compressed and stored so that the song currently being played may be played later.
  • a device for recording music being played by an audio device comprises a buffer for storing data corresponding to the music currently being heard from the audio device by a user, a user input device that receives user input at any time during the playing of the song indicating that the song is to be recorded, a song organizer that downloads the song recorded in the buffer based on the user input and compresses the downloaded song, and a memory for storing the compressed song so that the song currently being played may be played later.
  • a radio in accordance with yet another aspect of the invention, includes a receiver for receiving a radio broadcast and generating sound waves corresponding to the radio broadcast, a buffer memory that stores data corresponding to the music currently being heard on the radio by a user, a user input that receives user input at any time during the playing of the song indicating that the song is to be recorded; a controller for downloading and compressing the song recorded in the buffer based on the user input, and a memory that stores the compressed song so that the song currently being played may be played later.
  • Figure 1 is a diagram illustrating a preferred embodiment of a system for realtime wireless recording and compression in accordance with the invention
  • Figures 2 A - 2C are diagrams illustrating details of the buffer in the audio device.
  • FIGS. 3 A and 3B are a flowchart illustrating a preferred method of recording into buffer and downloading from buffer. Detailed Description of a Preferred Embodiment
  • the invention is particularly applicable to a real-time radio recording and compression device for downloading and compressing a song and it is in this context that the invention will be described. It will be appreciated, however, that the system and method in accordance with the invention has greater utility, such as to other types of audio devices and to various different types of audible content.
  • FIG. 1 is a diagram illustrating a preferred embodiment of a system 10 for real-time wireless recording and compression in accordance with the invention.
  • a radio receiver 12 may be the audio device although other audio devices may also be used.
  • the radio receiver may include an antennae 14 for receiving a plurality of radio waves that include the particular radio station to which the user is currently tuned.
  • a typical radio receiver may permit the user to tune into (using a tuner 16 and a user control unit 17) and listen to the radio station using a built- in speaker 18.
  • the radio receiver in accordance with the invention may include a central processing unit (CPU) 20 for controlling the operation of the audio device, a buffer 22 and a memory 24.
  • CPU central processing unit
  • the audio device in accordance with the invention may also include a removable memory device 26 so that the music downloaded from the radio station may be removed from the audio device and used with another audio device, such as a portable digital music player.
  • the buffer 22 may be a semiconductor memory device, such as RAM,
  • EEPROM or flash memory or it may also be a mass storage device, such as a hard disk drive.
  • the memory may be either a semiconductor memory device or a mass storage device.
  • the buffer 22 may store the song currently being played to the user, as described below, so that the user may, at any time during the song, select the song for downloading. To accomplish this, the buffer may start storing each song at its beginning. When the current song is completed, the buffer may be flushed so that a new song may be stored. If the user, using the user control unit 17, selects a song to be downloaded while the song is playing on the speaker, the song may be downloaded from the buffer to the memory 24 and stored in the memory.
  • the memory 24 may store a compression software application 28 that is executed by the CPU and compresses the selected song so that a compressed song 30 is stored in the memory 24 or in the removable memory 26.
  • the song currently playing on the audio device is downloaded and compressed in real-time. The details of downloading and storing the currently playing song will be described below with reference to Figure 3. Now, the operation of the buffer will be described.
  • Figures 2A - 2C are diagrams illustrating details of the buffer 22 in the audio device.
  • the buffer may have several different states.
  • the size of the buffer may be selected and therefore each audio device may have a different buffer size.
  • a larger buffer may be used that permits more than one song to be stored in the buffer at one time so that a user may go back one or more prior songs and download those songs.
  • a smaller buffer that holds a single song may be used.
  • Figure 2A illustrates the state of the buffer just before a new song is going to be played on the radio receiver since the buffer is considered to be empty. In most cases, the buffer may contain audio data from an old song, but that data is to be over-written with the new data for the new song.
  • Figure 2B illustrates the buffer when part of a song has been stored in the buffer and the buffer is half full.
  • Figure 2C illustrates a single song buffer just as the song has been completed. Now, a method for downloading and compressing music in accordance with the invention will be described.
  • Figures 3 A and 3B are a flowchart illustrating a preferred method 40 of recording into buffer and downloading from buffer.
  • the audio device stores the currently playing song in the buffer.
  • the audio device determines if the user has selected the current song for download. If the user has not selected the song yet, the method loops back to step 42. If the user has selected the current song for download, then the audio device may compress and begin to download the song from the buffer into the memory when the song is completed in steps 46 and 48. Once the download has been completed, the buffer may be written over with the next song in step 50.

Abstract

La présente invention concerne une technique qui, lors de l'écoute d'un dispositif audio, peut télécharger (46) et compresser (48) la chanson écoutée dans une mémoire locale (24) ou une mémoire amovible (26) même si cette chanson est en partie terminée. Pour ce faire, cette technique mémorise chaque chanson dans une mémoire tampon (22) dés que la chanson commence. Puis, à n'importe quel moment durant la diffusion de la chanson, l'utilisateur peut choisir de télécharger la chanson puisque celle-ci est stockée dans la mémoire (22). La mémoire tampon (22) peut être rafraîchie au début de chaque chanson.
