    摘要： A client device may receive encoded video via a transport stream based on a video coding protocol. When errors result in receiving the encoded video, the client device may use an Internet Protocol (IP) connection to recover from the error. For example, an encoder may insert markers inband in the transport stream, and a segmenter then segments the video using the markers. The content remains in the form of a continuous transport stream that is compatible with existing transport stream delivery mechanisms. When an error occurs, the client device can then determine a locator for a segment that can be used to recover from the error and requests the segment from a server through the IP connection. The server sends the segment to the client device at the level of the transport stream layer without adding another protocol layer to encapsulate the segment.

    摘要： A system and method for delivering content over the Internet from a content source to a destination is disclosed which includes the use of an overlay network, built on an underlying IP network. Additionally, error correction capability is added to the overlay network to allow the destination to reconstitute packets lost during the transmission over the Internet. In one embodiment, an overlay network is created using a plurality of overlay nodes, which may be geographically distributed. Each respective content source or destination is also a part of the overlay network. Overhead, capable of providing error correction capability, is added to the content flow as it enters the overlay network. As the content flow leaves the overlay network, this overhead is removed from the content flow. In the case of transmission errors across the overlay network, the overhead information is used to reconstitute lost or corrupted packets.

    摘要： A method includes receiving a data stream at a media device and extracting data from the data stream. The data corresponds to received media content. The method further includes storing the extracted data at a memory as stored media content and determining whether the stored media content corresponds to expected media content. The method also includes, in response to determining that the stored media content does not correspond to the expected media content, sending a content request to a server. The content request identifies a segment of the expected media content that does not correspond to the stored media content.

    摘要： The disclosure relates to reverse link lower layer assisted video error control. A method may encode video data, form a packet with the encoded video data, and transmit the packet across a wireless channel to an access network. A medium access control (MAC) layer may receive a negative acknowledgement (NAK) from the access network. The method may determine whether the received NAK is associated with a packet that contains video data. If the received NAK is associated with a packet that contains video data, the method may perform error control.

    摘要： Embodiments are disclosed herein that relate to multicast subscription based on forward error correction. One disclosed embodiment comprises a network-accessible server having a data-holding subsystem holding instructions executable by a logic subsystem to receive a content item, and form a first version of the content item having a first level of forward error correction and a second version of the content item having a second level of forward error correction. The instructions are further executable to stream the first version of the content item to a first multicast address, and while streaming the first version of the content item, stream the second version of the content item to a second multicast address.
