摘要： Described are computer-based methods and apparatuses, including computer program products, for scalable seamless digital video stream splicing. Data packets in a first video stream of bits are rearranged. Placeholder packets are created in a second video stream of bits. The first video stream of bits and the second video stream of bits are combined to generate a spliced stream by inserting data packets from the first video stream of bits into the placeholder packets in the second video stream of bits.

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 dynamic rate adjustment to splice video streams. A splicer receives a first compressed video stream of bits and buffers the first video stream of bits in a first buffer. The splicer receives a second compressed video stream of bits to splice into the first compressed video stream. The splicer buffers the second compressed video stream of bits in a second buffer. The splicer determines a departure time for a splice in-point of the second compressed video stream of bits. The splicer adjusts a rate of the first compressed video stream of bits, a rate of the second compressed video stream of bits, or both to achieve the departure time.

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.
