    Abstract: An electronic device with one or more processors, memory and a display obtains information that enables distribution of content between clients operating as peers in a peer-to-peer network. A first subset of the clients have first file format processing capabilities and a second subset of the clients have second file format processing capabilities. The peer-to-peer network enables access to a first set of file portions corresponding to the first file format and a second set of file portions corresponding to the second file format. The first set of file portions and the second set of file portions both include one or more shared file portions. The device provides, to one or more clients, information that enables the respective content to be shared over the peer-to-peer network that enables shared file portions be obtained either clients in the first subset of clients or clients in the second subset of clients.

    Abstract: A computer system generates a first decompressed media stream based on a first compressed media stream and provides the first decompressed media stream to a presentation device. While providing the first decompressed media to the presentation device: the computer system receives a content-transition indication indicating that a second decompressed media stream is to be provided to the presentation device instead of the first decompressed media stream. The computer system stores first buffered data corresponding to the first decompressed media stream and receives a second compressed media stream corresponding to the second decompressed media stream. After receiving the second compressed media stream, the computer system provides the first buffered data corresponding to the first decompressed media stream to the presentation device while preparing to generate the second decompressed media stream, and after preparing to generate the second decompressed media stream, provides the second decompressed media stream to the presentation device.

    Abstract: An electronic device with one or more processors, memory and a display receives a first request to display a first video stream and in response, displays the first video stream. The device allocates, in accordance with a bandwidth allocation, available bandwidth for receiving data at the device between receiving the first video stream and preloading one or more other, non-displayed, video streams. While displaying the first video stream on the display, the device preloads at least a portion of one or more non-displayed video streams based on the bandwidth allocation. After the preloading, the device receives a second request to display a second video stream. In response to receiving the second request, the device displays at least a portion of the second video stream on the display using a preloaded portion of the second video stream that was preloaded in accordance with the bandwidth allocation.

    Abstract: In accordance with an embodiment, described herein is a system and method for providing commercial (advertisement) detection in digital media environments. A media stream, for example, a video stream of television shows or movies, can be analyzed either in advance or in realtime, to determine commercial segments or blocks within the media stream, and to distinguish them from (non-commercial) content segments or blocks. In accordance with an embodiment, frame features, black spaces, cue points, or other segment or block information can be used to improve the accuracy and precision with which commercials are identified. Particular commercials can be identified, together with information as to the location of those commercials within the media stream. In accordance with an embodiment, the media streams can be used within an on-demand cloud-based media environment, which allows a user to select within a plurality of media channels, or to locate or skip particular commercials.
