Audio and video streaming for media effects

摘要

One embodiment of the present invention sets forth a technique for streaming digital media content with transition effects. Audio data may be modulated and received by the streaming device for an audio fade-in effect. Similarly, video data may be modulated to perform various visual effects. Such a technique allows for fading-in of audio and/or video, fading-out of audio and/or video, and effects that blend audio from different content and video from different content during a transition from one digital media content to a different digital media content or within the same digital media content. The modulated audio and video data to generate the audio or video effect during a transition may be precomputed or computed in real-time and transmitted to the streaming device. The streaming device switches between original unmodulated content streams and effect content streams when transitions are detected.

主权项

1. A method, comprising:
receiving a request from a streaming device for content associated with a video effect; and in response, transmitting to the streaming device at least a portion of a first video stream associated with the video effect and at least a portion of a first fade-in audio stream associated with the video effect, wherein the fade-in audio stream includes a modulated portion and a second portion, the second portion having volume levels that substantially match volume levels corresponding to an original audio stream that is associated with the video effect, and the modulated portion having volume levels that begin with a lowest volume level, increase across a fade-in envelope, and match a volume level corresponding to the original audio stream at a first point in time that delineates the end of the modulated portion and the start of the second portion.
