ENHANCED COLORFUL RING-BACK TONE BY MIXING CONTENT STREAMS IN REAL TIME

Methods and systems for enhanced Colorful Ring-Back Tone (eCRBT) services by mixing multiple digital content streams in real time are provided, including audio, video, data, text-based message, and hypermedia object streams. One or more properties of the content streams, such as volume or pitch of an audio stream, or brightness and layout of a video stream, are gradually altered such that a prominence of the an individual content stream is dynamically and seamlessly changed relative to other content streams with time. An eCRBT controller controls mixing and playing of digital content either based on an internal algorithm in an application server, or selections received from subscribers through provisioning interfaces. Personalized content streams can be mixed and played in real time based on interactive response received from a calling subscriber. Content may also be personalized based on caller by service provider. Subscriber-chosen content, subscriber's current availability information, and promotional or informational content from a service provider or a third party may be mixed seamlessly on top of each other.
