摘要： Described are computer-based methods and apparatuses, including computer program products, for input queued content switching using a playlist. A retrieval sequence is generated using a plurality of content requests based on content location information. A first portion of content is requested to be queued at a first content source, and a second portion of content is requested to be queued at a second content source. A content stream of the first portion and the second portion of content is generated using the retrieval sequence. The generating includes selecting the first portion of content from a queue associated with the first content source and transferring the first portion of content to an output buffer, then terminating transfer of the first portion of content and initiating transfer of the second portion of content from a queue associated with the second content source. The portion of content in the output buffer is transmitted to a client device.

摘要： Described are computer-based methods and apparatuses, including computer program products, for deterministically skewing synchronized events for content streams. A first content stream comprising at least one content processing location is buffered in a first buffer, wherein the first buffer is associated with a first processing delay parameter. A second content stream is buffered in a second buffer, the second content stream comprising at least one content processing location, the second buffer being associated with a second processing delay parameter that is different from the first processing delay parameter. The first content stream is processed at the at least one content processing location of the first content stream at a first content processing time based on the first processing delay parameter. The second content stream is processed at the at least one content processing location of the second content stream at a second content processing time based on the second processing delay parameter.

摘要： Described are computer-based methods and apparatuses, including computer program products, for canonical scheduling for heterogeneous content delivery. A content stream of bits is preprocessed by dividing the content stream of bits into data packets and assigning a timestamp to each data packet. The preprocessed content stream of bits is transmitted upon request from a receiver. A second timestamp based on the assigned timestamp from at least a portion of the respective data packets is established. The data packets are scheduled for transmission based on the second timestamp. The data packets are transmitted based on the schedule.

摘要： Described are computer-based methods and apparatuses, including computer program products, for efficiently storing transport streams. A first sequence of one or more packets associated with the first transport stream is received, the first sequence comprising one or more data packets. A storage packet is generated by selecting one or more packets from the first sequence, the storage packet comprising a packet header and the one or more data packets. One or more null packet insertion locations are identified in a second sequence of one or more packets associated with a second transport stream. Null packet insertion information is generated based on the one or more null packet insertion locations, the information including data indicative of a reconstruction parameter related to reconstructing the second sequence from the storage packet by inserting one or more null packets that are not stored in the storage packet, wherein the packet header includes the null packet insertion information. The storage packet is stored.
