Abstract: Techniques for seeding data among client machines, also referred to as boxes herein, are disclosed. To prevent the data distributed among the boxes from being illegitimately accessed or possessed, according to one aspect of the present invention, at least one of the data segments for a title cached locally in the boxes is made to miss some data portions that are stored separately. Essentially, the data segments are unusable without these data portions. When the title is ordered and an ordering box is authenticated, these data portions are then provided to complement the data segments so that a playback of the title becomes possible.

Abstract: Techniques for seeding data among client machines, also referred to as boxes herein, are disclosed. To prevent the data distributed among the boxes from being illegitimately accessed or possessed, according to one aspect of the present invention, each box is configured to perform what is referred to herein as a transcription process. In other words, when encrypted data is received, the data is decrypted and then re-encrypted with a key agreeable with a next box configured to receive the data.

Abstract: To ensure that media services are only provided to those authorized users or receiving devices, various conditional access mechanisms are provided to secure that media services are only received in those authorized. Different from a prior art conditional access system, an entitlement control message containing a master key can be sent directly to an ordering box. Depending on implementation, a secure session may be established between a server and an ordering box, such that all secured information including a master key may be transported. Further an ordering box does not need to possess a key or keys needed to decrypt an entitlement control message, such key(s) may be transported from time to time in a secure session established between the server and the ordering box.

Abstract: A system and method for providing multiple audio streams for a video over a network such as the Internet. The system comprises a server that includes an encryption unit and a slicing unit, a plurality of boxes, and an ordering box. The server encodes multiple audio streams and a single video to be sliced into segments. The sliced segments of multiple audio streams and the single video are seeded to a number of the plurality of boxes. This may be repeated for other videos with multiple streams. When the ordering box makes a request for a single video with a single audio, then the number of boxes with segments of the requested video and multiple audio streams, filters and sends the requested video and requested single audio stream to the ordering box. Similarly, multiple closed caption streams can be handled and provided like the audio streams.
