Abstract
Network services encode multimedia content, such as video, into multiple adaptive bitrate streams of encoded video and a separate trick play stream of encoded video to support trick play features. The trick play stream is encoded at a lower encoding bitrate and frame rate than each of the adaptive bitrate streams. The adaptive bitrate streams and the trick play stream are stored in the network services. During normal content streaming and playback, a client device downloads a selected one of the adaptive bitrate streams from network serviced for playback at the client device. To implement a trick play feature, the client device downloads the trick play stream from the network services for trick play playback.
Claims1
A method of supporting video streaming with trick play, comprising:
- encoding video into multiple adaptive bitrate streams and a corresponding trick play stream, each of the streams comprising files of encoded video;
- storing the files for each stream;
- receiving a playlist request for a selected one of the adaptive bitrate streams;
- sending a playlist identifying the stored files of the selected stream;
- receiving a playlist request for the trick play stream;
- and
- sending a playlist identifying the stored files of the trick play stream.
