    Abstract: A stream at a source device may be transmitted over multiple channels. At the input of the channels that packets from the stream may be grouped into chunks. Informational packets may be appended to the chunks. The informational packets may include sequencing information for the chunks and packet-to-packet timing information. The chunks may then be distributed over the multiple channels. After transmission over the channels, the informational packets may be extracted from the chunks. Reconstruction circuitry, at the destination device, may determine the sequence of the chunks at the source device based on the sequencing information. The reconstruction circuitry may also determine relative timings of the packets within the single stream based on the packet-to-packet timing information. The packets may be released from buffers in accord with the determined packet-to-packet timing information and the sequencing information to recreate the relative timings within the single stream at the destination device.

    Abstract translation: 源设备上的流可以在多个信道上传输。 在信道的输入处，来自流的分组可以被分组成块。 信息包可以附加到块。 信息分组可以包括块的排序信息和分组到分组定时信息。 然后，块可以分布在多个信道上。 在通过信道传输之后，可以从块中提取信息分组。 在目的地设备处的重建电路可以基于排序信息确定源设备处的块的顺序。 重建电路还可以基于分组到分组定时信息来确定单个流内的分组的相对定时。 可以根据确定的分组到分组定时信息和排序信息从缓冲器释放分组，以重新创建目的地设备的单个流内的相对定时。

    Abstract: An device and method for providing multiple adaptive bit rate (ABR) streams using a single transcoder is disclosed. The device receives a group of content segments for a media channel, and converts, using a transcoder, a first of the content segments from a source format to a first data format, a first time duration for converting the first content segment being less than a second time duration for receiving each group of segments. The converted segment is then sent to a client device. On receiving a request from the device for content segments in a second data format, the device performs an initialization of the transcoder to convert content segments from the source format to the second data format, the initialization being completed during a residual period of time, or “operational gap” produced by a difference between the first time duration and the second time duration.

    Abstract: A data communication architecture delivers a wide variety of content, including audio and video content, to consumers. The architecture employs channel bonding to deliver more bandwidth than any single communication channel can carry. The architecture includes intermediate network devices that may receive content and send content using different groups of communication channels. The network device may process content received across a first set of communication channels for transmission across a second set of communication channels different from the first set. Such processing may preserve a program order of the content during delivery to a destination device.
