Integrating a digital encoded-audio bit stream player in a radio-frequency telephone handset
View Patent ↗In one embodiment, a method of integrating a digital encoded-audio bit stream player in a radio-frequency (RF) telephone handset is disclosed. An RF connection is established between the RF telephone handset and an RF unit connected to a network, wherein communications between the RF telephone handset and the network pass through the RF unit. The RF telephone handset is switched from performing as a telephony device to performing as a digital encoded-audio bit stream player. Digital encoded-audio bit stream music is played from the RF telephone handset. The digital encoded-audio bit stream music playing from the digital encoded-audio bit stream player is muted when the RF telephone handset receives a telephone call. The RF telephone handset is switched from performing as a digital encoded-audio bit stream player to performing as a telephony device while the telephone call is active.
1. A method of integrating a digital encoded-audio bit stream player in a radio-frequency (RF) telephone handset, comprising:
establishing an RF connection between the RF telephone handset and an RF unit connected to a network, wherein communications between the RF telephone handset and the network pass through the RF unit;
switching the RF telephone handset from performing as a telephony device to performing as a digital encoded-audio bit stream player;
playing digital encoded-audio bit stream music from the RF telephone handset;
muting the digital encoded-audio bit stream music playing from the digital encoded-audio bit stream player when the RF telephone handset receives a telephone call; and
switching the RF telephone handset from performing as a digital encoded-audio bit stream player to performing as a telephony device while the telephone call is active, wherein:
(i) the RF telephone handset comprises:
a digital signal processor, and
a digital-to-analog converter connected to the digital signal processor;
(ii) the step of playing digital encoded-audio bit stream music from the RF telephone handset comprises the steps of:
the digital signal processor decoding a digital encoded-audio bit stream to produce a digital reconstructed audio signal,
the digital-to-analog converter converting the digital reconstructed audio signal to an analog audio signal, and
outputting the analog audio signal to the user;
(iii) the step of muting digital encoded-audio bit stream music playing from the digital encoded-audio bit stream player comprises the digital signal processor pausing decoding the digital encoded-audio bit stream; and
(iv) the method further comprises:
the digital signal processor receiving a telephone audio signal from the RF unit connected to the network,
the digital signal processor passing the telephone audio signal to the digital-to-analog converter,
the digital-to-analog converter converting the telephone audio signal to an analog audio signal, and
outputting the analog audio signal to the user.
2. The method of claim 1 , wherein:
the digital encoded-audio bit stream music is pre-loaded before the step of playing.
3. The method of claim 1 , wherein:
the digital encoded-audio bit stream music is played substantially real-time as it is received by the RF telephone handset.
4. The method of claim 1 , wherein:
the digital encoded-audio bit stream player is an MPEG audio player, and
the digital encoded-audio bit stream music is MP3 music.
5. An apparatus for integrating a digital encoded-audio bit stream player in a radio-frequency (RF) telephone handset, comprising:
means for playing pre-loaded digital encoded-audio bit stream music from the RF telephone handset;
means for switching the RF telephone handset from performing as a telephony device to performing as a digital encoded-audio bit stream player;
means for establishing an RF connection between the RF telephone handset and an RF unit connected to a network, wherein communications between the RF telephone handset and the network pass through the RF unit;
means for muting digital encoded-audio bit stream music playing from the digital encoded-audio bit stream player when the cordless telephone receives a telephone call; and
means for switching the RF telephone handset from performing as a digital encoded-audio bit stream player to performing as a telephony device while the telephone call is active, wherein:
(i) the means for playing digital encoded-audio bit stream music from the RF telephone handset comprises:
a digital signal processor located in the RF telephone handset and adapted to decode a digital encoded-audio bit stream to produce a digital reconstructed audio signal, and
a digital-to-analog converter located in the RF telephone handset and connected to the digital signal processor to convert the digital reconstructed audio signal to an analog audio signal for outputting to the user;
(ii) the means for muting digital encoded-audio bit stream music playing from the digital encoded-audio bit stream player comprises the digital signal processor;
(iii) the digital signal processor is adapted to:
pause decoding the digital encoded-audio bit stream,
receive a telephone audio signal from the base unit, and
pass the telephone audio signal to the digital-to-analog converter; and
(iv) the digital-to-analog converter is adapted to convert the telephone audio signal to an analog audio signal for outputting to the user.
6. The apparatus of claim 5 , wherein:
the digital encoded-audio bit stream player is an MPEG audio player, and
the digital encoded-audio bit stream music is MP3 music.
