Abstract
A hybrid player and a method of using the hybrid player to play a first stream and a second stream simultaneously while muting the second stream. The first stream continues to play until it is desired to replace the first stream with the second stream. Simultaneously, the first stream is muted and the second stream is unmated while simultaneously increasing a volume of the second stream.
Description
HYBRID PLAYER FOR STREAMING AUDIO
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
This invention relates to a method of coherent receiving and playback of multiple streaming audio. In particular, this invention provides a hybrid player and a method for seamless integration of multiple audio streams into single uninterrupted continuous audio playback at the receiving end.
DESCRIPTION OF THE PRIOR ART
In order to deliver an audio commercial or replace one content with another content during audio transmission, continuous data flow from one source gets interrupted so that signal from another source of data can be processed and played. This behaviour causes temporary loss of audible signal and provides an unpleasant listening experience to a listener due to the time delay that occurs when switching from one content to another content. A long pause without any audio signal can be very annoying to listeners. For example, in satellite radio transmissions or transmissions over the internet, long silent pauses can exist when the content provider is replacing one content with another content.
SUMMARY OF THE INVENTION
The present invention provides a method to integrate multiple coherent streams and seamlessly infuse one into another in real time without causing loss of audible signal. The method of the invention may also be used to provide content removal and replacement from live internet audio feed in accordance to the "AFTRA" ruling.
It is an object of the present invention to provide a hybrid player and to provide a method of coherent receiving in playback of multiple streaming audio whereby two or more audio streams are loaded simultaneously into a hybrid player with one of the streams being audible and the other stream being muted. When it is desired to replace one stream with another stream, the volume of the first stream is muted and the volume of the second stream is unmuted simultaneously for a smooth transition without any long silent pause.
A method of moving from a first audio stream to a second audio stream without loss of audible signal comprises loading the first stream and the second stream into a hybrid player, playing the streams simultaneously while muting the second stream, continuing to simultaneously play the streams until the first stream approaches a termination point. At the termination point, the method comprises muting the first stream and unmuting the second stream while simultaneously increasing the volume of the second stream, thereby audibly moving from the first stream to the second stream without interruption in the audible signal.
A method of moving from one audible stream to another audible stream of multiple streams without loss of audible signal comprises loading two or more audio streams into a hybrid player while muting all of the streams but one. When it is desired to move to a new stream, muting the audible stream and unmuting another stream simultaneously.
A hybrid player for receiving and playing two audio streams simultaneously comprises a means for playing the streams simultaneously with a volume of a first stream being unmuted and a volume of a second stream being muted, the player being controllable to mute the volume of the first stream and unmute the volume of the second stream simultaneously when it is desired to audibly move from one stream to another.
A hybrid player can play two or more streams simultaneously while muting all of the streams but one, the hybrid player being controllable to change the one stream that is unmuted and streams that are muted.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a block diagram showing a hybrid player process; and Figure 2 is a front view of a hybrid player.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
The proposed method is based on simultaneous use of multiple instances of an audio player and synchronized volume control over multiple streams.
In order to eliminate loss of audible signal two or more streams begin to simultaneously load each into correspondent instance of an audio player with muted volume leaving not muted only the stream which content is to be played first (typically this stream represents pushed commercial). A "pushed commercial" is an online commercial that cannot be deleted or prematurely terminated by a user. At the end of the initially played content, hybrid player processing module eliminates correspondent instance of the player from its processing graph and simultaneously gradually increase volume of the second live stream, etc - thus delivering uninterrupted continuous flow of audible signal providing a pleasurable listening experience.
While the hybrid player uses multiple instances of the audio player, it has single user GUI [graphical user interface] and set of controls that performs required functions to synchronously operate the streams.
The proposed method operates in real-time using processing logic described in Figure 1. The hybrid player can simultaneously play a first stream and a second stream with the first stream being unmuted and the second stream being muted. A controller changes the first stream to mute and the second stream to unmuted when it is desired to move from one stream to the other while avoiding a long silent pause. Alternatively, the hybrid player can play more than two streams simultaneously with all but one of the streams being muted. As a further alternative, the hybrid player can play any two streams of multiple streams simultaneously with one stream being muted and another stream being unmuted at any given time. A controller can simultaneously change one mute stream to unmute and the unmuted stream to mute as well as changing which streams are being played. When moving from a mute stream to an unmute stream, the hybrid player is controlled to be playing that stream before the change in order to avoid any long silent pauses. While the hybrid player and method of the present invention is preferably used with online audio signals over the internet, the player and method can be used with other audio signals as well. The hybrid player and one controller can be electronic versions created and controlled as computer software or they can be a combination of hardware and software versions.
The termination point can be the end of a particular stream or it can be a point where a user desires the stream to end and to be replaced by another stream.
In Figure 1, a hybrid player has two streams a first stream 1 and a second stream 2. The first stream is typically a commercial and the second stream is typically a live audio feed.
The first stream is unmuted and the second stream is muted. A volume control allows a volume of said second stream to be controlled while said first stream is muted and vice versa. The first stream has a stop at which said first stream has a termination point. At said termination point, said first stream is muted and simultaneously said second stream is unmuted while simultaneously a volume of said second stream is increased. During the time when one of said streams is muted and another of said streams is unmuted, said muted stream can be replaced by a new muted stream. The new muted stream subsequently is unmuted when the other stream is muted while simultaneously increasing a volume of the stream that is unmuted.
In Figure 2, a hybrid player 6 has a power switch 8 and a volume control 10 allows the volume of the first stream to be adjusted as the sound stream is muted and vice versa.
While the hybrid player is described as having a first stream and a second stream, the hybrid player can be designed to have more than two streams where one of said streams is unmuted while a remainder of said streams is muted. The unmuted stream can be muted and simultaneously replaced with another stream by unmuting that stream while simultaneously increasing the volume of the unmuted stream.

The termination point can be the end of a particular stream or it can be a point where a user desires the stream to end and to be replaced by another stream.
In Figure 1, a hybrid player has two streams a first stream 1 and a second stream 2. The first stream is typically a commercial and the second stream is typically a live audio feed.
The first stream is unmuted and the second stream is muted. A volume control allows a volume of said second stream to be controlled while said first stream is muted and vice versa. The first stream has a stop at which said first stream has a termination point. At said termination point, said first stream is muted and simultaneously said second stream is unmuted while simultaneously a volume of said second stream is increased. During the time when one of said streams is muted and another of said streams is unmuted, said muted stream can be replaced by a new muted stream. The new muted stream subsequently is unmuted when the other stream is muted while simultaneously increasing a volume of the stream that is unmuted.
In Figure 2, a hybrid player 6 has a power switch 8 and a volume control 10 allows the volume of the first stream to be adjusted as the sound stream is muted and vice versa.
While the hybrid player is described as having a first stream and a second stream, the hybrid player can be designed to have more than two streams where one of said streams is unmuted while a remainder of said streams is muted. The unmuted stream can be muted and simultaneously replaced with another stream by unmuting that stream while simultaneously increasing the volume of the unmuted stream.
