    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: An electronic device with one or more processors, memory and a display obtains information that enables distribution of content to a plurality of clients having different file format processing capabilities. The device provides, to a first client, first information that enables access to respective content in a first file format and provides, to a second client, second information that enables access to the respective content in a second file format different from the first file format. The first information identifies a first set of file portions that can be combined to generate the respective content in the first file format. The second information identifies a second set of file portions that can be combined to generate the respective content in the second file format. The second set of file portions includes one or more shared file portions that are included in the first set of file portions.

    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: 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. While providing the first decompressed media stream to the presentation device, the computer system receives a content-transition indication to switch to a second decompressed media stream. In response to receiving the content-transition indication, the computer system selects a first transition point in first content corresponding to the first compressed media stream and selects a second transition point in second content corresponding to the second compressed media stream. The second transition point is selected in accordance with a bandwidth available for receiving the second compressed media stream and the first transition point is selected based on the second transition point. The computer system requests the second compressed media stream starting at the second transition point and ceases to provide the first decompressed media stream at the first transition point in the first content.

    Abstract: An electronic device obtains a file header for a file that corresponds to a plurality of clusters. The file header includes a cluster index that enables coarse searching within the file. At least one of the file header and the file omits information that is known to or calculable by the device for extracting content from the file. In response to receiving a request to seek to a position within the file, the device identifies a cluster that includes content that corresponds to the position based on the cluster index and obtains a cluster header that enables fine searching within the cluster. After obtaining the cluster header, the device identifies, within the cluster, the content that corresponds to the position based on the content index and provides at least a portion of content corresponding to the file to a presentation device, starting with the content that corresponds to the position.
