Enabling trick plays during VBR playback of a CBR transmitted media file |
摘要 |
A method and system for enabling trick plays during a variable bit rate (VBR) playback of a media file transmitted to a user media device as a constant bit rate (CBR) flow includes determining a plurality of access points within the media file. The media file is configured to be played back from each of the plurality of access points. A minimum buffer value is calculated for each of the plurality of access points. The minimum buffer value identifies a minimum amount of the media file to transmit to the user media device before beginning playback of the media file from each of the plurality of access points to substantially ensure that the media file is configured to be played back from each of the plurality of access points continuously and uninterruptedly at a variable bit rate.
