Abstract
Systems, methods and devices are provided to reduce change latency and/or to provide a picture-in-picture (PIP) feature within a placeshifted media stream. As the viewer receives a primary stream containing selected programming, secondary programming that is likely to be of interest to the user is predicted. A secondary stream containing the predicted content is obtained at the same time as the primary stream selected by the user. The secondary stream may be of lower quality than the primary stream to preserve network bandwidth. If the user subsequently selects the predicted secondary content, the previously-obtained content can be quickly provided as an output to the display. Alternately, the primary and secondary streams may be simultaneously output to the display in PIP or another manner.
