Abstract: A device may generate a media stream to be shared with other users by building a media graph, comprising a series of interconnected processing units that perform various processing tasks. However, the time involved in generating the media graph may delay the initialization of the media stream, and adjusting properties of the media stream (such as resolution or codec) may result in an interruption of the media stream while a new media graph is built. Instead, a media graph cache may be provided to cache a set of media graphs, which may be interchangeably selected for rapid initialization and adjusting of media stream properties. The media component (e.g., a video camera) may also be configured to promote rapid adjustments to some media stream properties, while maintaining other properties (e.g., field of view and white balance) for a smooth transition between media stream property sets.

Abstract: A method for stabilizing delay during conversion between Standard Definition (SD) video and High Definition (HD) video includes the step of establishing an integer divide ratio (M/N) corresponding to a ratio of clock rates with the output and input formats.

The video frame can be transferred at the known repetitive interval to provide coarse control over the input-to-output video delay. A separate fine tuning control (delay block) is provided to enable any programmable delay in video throughput to be accommodated to an accuracy of ±0.5 output pixel periods.
