    摘要: Generation of live streaming indices is disclosed that stores a media stream recording from a live event. Seek points are added to a fixed-length index memory corresponding to each point of the media stream separated at a first interval. In response to the fixed length being reached, alternate ones of the seek points are deleted up to a predefined percentage of the fixed length. Location indicators are added where the deletions caused the previous interval to be altered and at the end of the previous seek points remaining in the index memory. A new interval is then calculated, which corresponds to the altered interval, after which new seek points are added beginning at the second location indicator to the index memory corresponding to the points in the media stream separated by the new interval.

    摘要: Methods, systems, and apparatus, including encoded computer programs, for using free space set aside in hierarchical data documents, such as multimedia documents containing video and audio data. In one aspect, a method includes obtaining new data to be added to a document having a hierarchical structure, where the document includes stored data and free spaces at different nodes; determining whether a first node in the structure includes a first free space of a size sufficient for the new data; using the first free space in the first node to add the new data to the document when the size is sufficient; and when the size is insufficient: identifying a second node including a second free space in the structure, moving some of the second free space to the first free space, and using the increased first free space in the first node to add the new data to the document.
