Abstract: During encoding, blank frames may be substituted for text images in video content, encoding the blank frames instead of the text images. The text images may be any kind of text images such as opening credits, ending credits, and so on. The selection of text images to substitute may be performed by optical character recognition, user selection and so on. The text associated with the text images may be embedded in the encoded video. If the text is already embedded, an indicator of the location may be added. If not, the text may be derived from the text image using optical character recognition and then embedded. When decoded, the encoded video may be analyzed to determine whether blank frames were substituted for text images. Embedded text associated with the text images may then be located, obtained, and added to the decoded video. Thus, the original text images are essentially reconstructed.

Abstract: A system and method for determining and displaying return-on-investment (ROI) of components on a network is described. The system includes one or more processes that initiate and receive data streams directly or indirectly from components on the network or from other databases on the network. A dependency tree is created for each component relating each component to other components and to information characterizing the component. A portal is provided to export data feeds to other systems on the network and to generate reports and display usage information on each component on the network. Usage information may be grouped or summarized according to business function or by top level manager.

Abstract: Techniques and devices for depolarizing light and producing a variable differential group delays in optical signals. In one implementation, an input optical beam is split into first and second beams with orthogonal polarizations. One or two optical reflectors are then used to cause the first and second optical beams to undergo different optical path lengths before they are recombined into a single output beam. An adjustment mechanism may used implemented to adjust the difference in the optical path lengths of the first and second beams to produce a variable DGD. When the depolarization of light is desired, the difference in the optical path lengths of the first and second beams is set to be greater than the coherence length of the input optical beam.
