SYSTEMS AND METHODS FOR IMPLEMENTING CROSS-FADING, INTERSTITIALS AND OTHER EFFECTS DOWNSTREAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240257820 titled 'SYSTEMS AND METHODS FOR IMPLEMENTING CROSS-FADING, INTERSTITIALS AND OTHER EFFECTS DOWNSTREAM

The patent application describes systems and methods for cross-fading or processing multiple information streams on user devices like phones, tablets, computers, or mp3 players.

• Utilizes a single decoder on the client device to pre-fetch and decode elements involved in a cross-fade at faster than real-time.
• Stores next elements in an input buffer, decodes them, and stores them in a decoded sample buffer before the required presentation time.
• Accesses decoded audio clips at the appropriate time to perform cross-fade, mix, or other effects without requiring synchronized simultaneous decodes.

1. 1. 1. Potential Applications:

This technology can be used in music streaming services, audio editing software, and multimedia applications to enhance user experience with seamless transitions between audio clips.

1. 1. 1. Problems Solved:

- Eliminates the need for synchronized simultaneous decodes, reducing processing load on the client device. - Enables smooth cross-fading and mixing of audio clips without interruptions or delays.

1. 1. 1. Frequently Updated Research:

Researchers may be exploring advancements in audio processing algorithms, real-time decoding techniques, and optimization strategies for multimedia playback on consumer devices.

1. 1. 1. 1. Questions about Cross-Fading Technology:

1. How does this technology improve the user experience in multimedia applications? 2. What are the key advantages of using a single decoder for processing multiple audio clips on client devices?

Original Abstract Submitted

systems and methods are presented for cross-fading (or other multiple clip processing) of information streams on a user or client device, such as a telephone, tablet, computer or mp3 player, or any consumer device with audio playback. multiple clip processing can be accomplished at a client end according to directions sent from a service provider that specify a combination of (i) the clips involved; (ii) the device on which the cross-fade or other processing is to occur and its parameters; and (iii) the service provider system. for example, a consumer device with only one decoder, can utilize that decoder (typically hardware) to decompress one or more elements that are involved in a cross-fade at faster than real time, thus pre-fetching the next element(s) to be played in the cross-fade at the end of the currently being played element. the next elements(s) can, for example, be stored in an input buffer, then decoded and stored in a decoded sample buffer, all prior to the required presentation time of the multiple element effect. at the requisite time, a client device component can access the respective samples of the decoded audio clips as it performs the cross-fade, mix or other effect. such exemplary embodiments use a single decoder and thus do not require synchronized simultaneous decodes.
