摘要： A device may not trust another device with which it is in communication. To establish trust, a first device may send a second device an indication of signed code that is stored in a protected memory of the first device. Based on determining that the first device is a trusted device, the second device may send the first device an encrypted content asset, a decryption key associated with the content asset, and/or an encryption key associated with the content asset.

摘要： A device may receive a manifest that identifies a plurality of content fragments associated with a content asset. The device may receive or access instructions for inserting secondary content into a location of the content asset that does not align with the boundaries between the content fragments. Based on the received instructions, the playback device may generate updated manifest information that identifies a first modified content fragment and a second modified content fragment. The location for inserting the secondary content in the updated manifest information may align with a new boundary of the first modified content fragment or the second modified content fragment. The device may share the updated manifest information, and may receive a modified manifest file, or content asset, comprising the modified content fragments.

摘要： Methods and systems for improved failover techniques are described herein. A failure associated with a content source may lead to a computing device becoming unable to output all or part of content that was requested from the content source prior to the failure. The computing device may have received a portion of a manifest associated with the content prior to the failure. The failover techniques described herein may enable the computing device to continue receiving portions of the content despite the failure. For example, an additional portion of the manifest may be modified such that the computing device may request additional portions of the content from another content source without requiring a retuning procedure.

摘要： A content provider in a content distribution system may be configured to reduce latency in a content distribution system by storing multiple frames from a sequence of frames in different buffers and encrypting, in parallel, the frames stored in the different buffers. For example, the content provider may encrypt each buffer via a different instruction pipeline of a processor.
