Abstract: Methods of converting an open group of pictures (GOP) to a Closed GOP are described that remove backward references to the GOP prior to the GOP undergoing conversion in an Open GOP interframe-encoded video stream. Within the GOP undergoing conversion, bipredictive frames with backward references to the prior GOP are replaced with frames referring only to the I frame of the GOP undergoing conversion, which is flagged as an IDR frame. Consolidation and assembly of video clips that are encoded using Open GOP compression schemes generally result in broken interframe references between GOPs. To address this, existing methods involve significant decoding and re-encoding of edited video sequences. The described methods serve to break the backward chain of references in the encoded stream, resulting in reduced re-encoding requirements, with attendant reduced quality degradation of the edited sequence.

Abstract: Featured is a method for controlling work of a project, that is particularly suited for controlling development of files of a software project. Such a method broadly includes defining S status levels (S?2), where the number and definition of each status level relates to at least certain of the workflow paths of the project workflow and defining U user statusing rights sets (U?2), one user rights set for each type of user. The method also includes classifying each work item as one of being within or being without the workflow and using the S status levels to define a work status for each work item classified as being within the workflow. The method also includes assigning the work item and a work status change control process whereby changes in work status are permitted based on the user statusing rights. Also featured is a computer program, program code for execution on a microprocessor and a computer system embodying such program code.
