摘要： Methods and systems are provided for encoding content using a first encoding algorithm to produce first encoded content. Content can also be encoded using a second encoding alaorithm to produce second encoded content, where the second encoded content can comprise data that can be used to reconstruct the first encoded content. At any time relative to the encoding, a request for the content can be received from a user device. In response to receipt of the request, the first encoded content is transmitted to the user device and the second encoded content is transmitted to the user device.
