Abstract: An electronic device with one or more processors, memory and a display obtains a file header for a file that corresponds to a plurality of separately indexed clusters. The file is divided into segments one or more of which include multiple sequential clusters. The file header includes a segment index that enables identification of a segment that includes requested content. The device receives a request to seek to a respective position within the file. In response, the device identifies a first segment that includes content that corresponds to the respective position based on the segment index, obtains the first segment, and obtains a content index for a respective cluster within the first segment. After obtaining the first segment and the content index, the device identifies respective content within the respective cluster that corresponds to the respective position based on a content index and provides the respective content to a user.

Abstract: A computer system receives a content-transition indication to provide a second decompressed media stream to a presentation device instead of providing a first decompressed media stream. In response to receiving the content-transition indication, the computer system ceases to receive a first compressed media stream corresponding to the first decompressed media stream and continues to provide the first decompressed media stream to the presentation device using first buffered data. The computer system selects a transition point for a second compressed media stream, corresponding to the second decompressed media stream, based on a quantity of data of the second compressed media stream to be buffered. While continuing to provide the first decompressed media stream to the presentation device using the first buffered data, the computer system receives and buffers the second compressed media stream starting at the transition point. The computer system provides the second decompressed media stream to the presentation device.

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: Technology for generating, reading, and using machine-readable codes is disclosed. There is a method, performed by an image capture device, for reading and using the codes. The method includes obtaining an image, identifying an area in the image having a machine-readable code. The method also includes, within the image area, finding a predefined start marker defining a start point and a predefined stop marker defining a stop point, an axis being defined there between. A plurality of axis points can be defined along the axis. For each axis point, a first distance within the image area to a mark is determined. The distance can be measured from the axis point in a first direction which is orthogonal to the axis. The first distances can be converted to a binary code using Gray code such that each first distance encodes at least one bit of data in the code.

Abstract: A computer system generates, using a first codec, a first decompressed media stream based on a first compressed media stream. The computer system provides the first decompressed media stream to a presentation device. While providing the first decompressed media stream to the presentation device, the computer system receives a second compressed media stream corresponding to a second decompressed media stream to be presented by the presentation device and initializes a second codec after the first codec has stopped decompressing the first compressed media stream so that no more than one codec is decompressing compressed media at a time. The computer system generates, using the initialized second codec, the second decompressed media stream and provides the second decompressed media stream to the presentation device instead of providing the first decompressed media stream to the presentation device.

Abstract: A computer system receives a first compressed media stream and stores corresponding data in a first compressed buffer. The computer system generates a first decompressed media stream based on the first compressed media stream. While providing the first decompressed media stream to a 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. While continuing to generate the first decompressed media stream using the first compressed buffer, the computer system receives a second compressed media stream corresponding to the second decompressed media stream and stores corresponding data in a second compressed buffer. After storing the data in the second compressed buffer, the computer system provides a second decompressed media stream, based on the second compressed media stream, to the presentation device instead the first decompressed media stream.
