  • Publication number: 20120106329
    Abstract: A method and apparatus for reporting events in a machine-to-machine environment are provided. Upon detection of an event, a determination is made whether to report the event with or without a delay. If the event is to be reported with a delay, then reporting is delayed for a period of time. If an event notification is received prior to the expiration of the delay period, then the reporting of the event may be canceled as event has already been reported by another element. If not, then another determination is made whether to report the event with or without another delay. This process continues until either the event has been reported or an event notification corresponding to the event has been received from another element.

  • Publication number: 20120102154
    Abstract: Methods and systems for transcoding in a cloud computing platform are disclosed. According to an embodiment, a receiver receives an uploading file by one data block at a time, and stores the received data blocks in various storage modules. Small segment files are then generated when the size of the received data blocks is larger than a threshold. A transcoder transcodes the small segment files from one format such as a bit rate or a frame size to another while the receiver is still receiving a new data block. The transcoded small segment files may be stitched together to form a stitched file, which may be stored in a storage module to be downloaded through a content distribution network (CDN). The transcoded small segment files may be passed to streaming servers for streaming over a network while the receiver is still receiving a new data block of the uploading file.
