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.
摘要翻译： 在一个示例中，从多个存储模块请求多媒体内容。 每个存储模块检索所请求的部分，这些部分通常存储在每个存储模块处的多个存储设备上。 每个存储模块独立地确定何时从存储器中检索数据文件的所请求部分，并将这些部分从存储器发送到数据队列。 基于传送模块的容量和/或与请求相关联的数据速率，每个存储模块将数据文件的各部分传送到传送模块。 递送模块根据从多个存储模块接收的数据文件的部分生成排序的数据段，并将排序的数据段发送给请求者。

摘要： Described are computer-based methods and apparatuses, including computer program products, for statistical multiplexing of compressed video streams. A deadline of a packet of a compressed video stream is computed based on a program clock reference value of the packet. A plurality of packets, which includes the packet, is sorted based on deadlines corresponding to the packets. A next packet from the sorted plurality of packets is selected, the next packet having a corresponding deadline nearest to a system clock time. The next packet is transmitted.

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 herein are techniques, including methods and systems, including computer program products, for unicast delivery of multimedia content. A broadcast program and a video- on-demand program are ingested by a video delivery module. At least a portion of the broadcast program and at least a portion of the video-on-demand program are stored. The broadcast program, the video-on-demand program, or both are delivered as a unicast video stream to a first single subscriber through a multiplexer connected to a plurality of subscribers.
