Abstract: 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.

Abstract translation: 本发明的一个实施例提出了一种用于流式传输具有过渡效果的数字媒体内容的技术。 音频数据可以被流式传输设备调制和接收，以实现音频淡入淡出。 类似地，可以调制视频数据以执行各种视觉效果。 这种技术允许在从一个数字媒体内容到另一个数字媒体内容的转换期间，音频和/或视频的淡入淡出，音频和/或视频的淡入淡出以及混合来自不同内容的不同内容和视频的音频 媒体内容或同一数字媒体内容内。 用于在转换期间产生音频或视频效果的调制音频和视频数据可以被预先计算或实时计算并被发送到流传输设备。 当检测到转换时，流设备在原始未调制内容流之间切换并影响内容流。
