    Abstract: In one embodiment, a first value is computed on a networked computing device, the first value being associated with storing a recording of a broadcast video at a first cloud storage device situated in a first one of a plurality of regions, for playback on a remote client device situated in the first one of the plurality of regions, the first value being a measure of user consumption patterns and use of computing and network resources. A second value is computed on the networked computing device, the second value being associated with storing the recording of the broadcast video at a second cloud storage device situated in a second one of the plurality of regions, for playback on a remote client device situated in the second one of the plurality of regions, the second value being a measure of user consumption patterns and use of computing and network resources. The first and second values are compared on the networked computing device in order to determine a preferred storage region, the recording of the broadcast video is stored on the one of the first cloud storage device and the second cloud storage device in the preferred storage region, and the one of the first cloud storage device and the second cloud storage device in the preferred storage region is instructed to store the recording of the broadcast video. Related hardware, systems, and methods are also described.

    Abstract: In one embodiment, a cloud digital video recorder system includes a broadcast content receiver operative to receive broadcast content, a spill agent operative to generate a plurality of different time-period, non-user initiated, recording requests, and a content recorder operative to receive a plurality of user-initiated recording requests of a plurality of users, receive the plurality of different time-period, non-user initiated, recording requests of the spill agent, record the broadcast content into a content storage according to the plurality of user-initiated recording requests and the plurality of different time-period, non-user initiated, recording requests, receive a user-initiated retroactive recording request for a first portion of the broadcast content which has already been recorded to the content storage, and generate a pseudo-recording from the first portion of the broadcast content stored in the content storage according to the user-initiated retroactive recording request. Related apparatus and methods are also described.

    Abstract: A method of content recording and playback is carried out in a receiving device by selecting one of a plurality of digital content streams (80, 82, 84), which have respective distribution arrangements. A content segment (90) of a review buffer (88) is established and configured for the one content stream. While recording the one content stream in the review buffer (90), a content source change operation is performed to record another content stream in the review buffer (88) by discontinuing recording of the one content stream, and iterating establishing, configuring and recording with a new content segment (92). Recorded content of the content segment (90) and new content segment (92) are stored in respective data stores (102, 100). The content streams may be replayed in an order or a reverse order of recording thereof by retrieving data from respective content segments or data stores. Related apparatus is also described.

    Abstract translation: 通过选择具有各自的分配结构的多个数字内容流（80,82,84）中的一个，在接收设备中执行内容记录和重放的方法。 为一个内容流建立和配置审阅缓冲器（88）的内容片段（90）。 在将一个内容流记录在审阅缓冲器（90）中的同时，执行内容源改变操作，通过中断一个内容流的记录来再现在审阅缓冲器（88）中记录另一个内容流，并且迭代建立，配置和记录 新内容片段（92）。 内容段（90）和新内容段（92）的记录内容被存储在各自的数据存储区（102,100）中。 可以通过从相应的内容段或数据存储中检索数据，以其记录的顺序或相反的顺序重播内容流。 还描述了相关装置。
