    摘要: In one example, multimedia content is requested from a plurality of storage modules. Each storage module retrieves the requested parts, which are typically stored on a plurality of storage devices at each storage module. Each storage module determines independently when to retrieve the requested parts of the data file from storage and transmits those parts from storage to a data queue. Based on a capacity of a delivery module and/or the data rate associated with the request, each storage module transmits the parts of the data file to the delivery module. The delivery module generates a sequenced data segment from the parts of the data file received from the plurality of storage modules and transmits the sequenced data segment to the requester.

    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 policy-based content insertion. A client device transmits to a content server a request for the delivery of content. The content server modifies the request based on an ingress policy. The content server transmits the modified request to a second server where the second server processes the request. The second server transmits a reply to the modified request to the content server. The reply includes a content insertion instruction. The content server transmits the content to the client device based on the content insertion instruction and/or one or more egress policies.
