摘要： Methods, systems, and apparatuses are described for fault tolerant network storage and delivery of recorded content. Two or more network digital video recorders may each receive a plurality of requests to record, archive, and/or play back content items, such as television programs. Each network digital video recorder may receive capacity reports of statistics such as storage and/or bandwidth from one or more other network digital video recorders. At least one of the network digital video recorders may determine whether, based on a network capacity, to record, archive, and/or playback content items. The methods, systems, and apparatuses may accommodate equipment failures that lead to partitions between network digital video recorders.

摘要： Methods and systems are described for storing content. One or more sections of the stored content may be subdivided into user-specific portions and common portions. The user-specific portions may be stored in user-specific storage associated with corresponding accounts of a plurality of user accounts. The common portions may be stored in common storage associated with the plurality of user accounts. User accounts may request access to the stored content. One or more caching criteria may be used to determine whether to cache any common portions of the stored content. Requests for the content may be processed using the common portions stored in the cache storage.

摘要： A digital content storage and delivery system (DCSDS) includes a network interface to communicate data between the DCSDS and a destination device via a network data communication link having limited bandwidth. An input interface receives digital content for handling by the DCSDS. A storage architecture stores recorded video content on behalf of subscriber end users for on-demand playback via the network data communication link, and it caches live streaming video content for distribution via the network data communication link. The DCDS may monitor bandwidth usage of the network data communication link, determine current bandwidth demand for playback of recorded video content stored at the storage architecture, and reserve at least some of the limited bandwidth of the network data communication link to satisfy the determined current bandwidth demand. The available bandwidth is allocated to support distribution of live streaming video from the DCSDS.

摘要： Techniques and mechanisms described herein facilitate the storage of digital media recordings. According to various embodiments, a system is provided comprising a processor, a storage device, Random Access Memory (RAM), an archive writer, and a recording writer. The archive writer is configured to retrieve a plurality of small multimedia segments (SMSs) in RAM and write the plurality of SMSs into an archive container file in RAM. The single archive container file may correspond to a singular multimedia file when complete. New SMSs retrieved from RAM are appended into the archive container file if the new SMSs also correspond to the singular multimedia file. The recording writer is configured to flush the archive container file to be stored as a digital media recording on the storage device once enough SMSs have been appended by the archive writer to the archive container file to complete the singular multimedia file.

摘要： Apparatus and methods for managing provision of digital content within a content distribution network. In one embodiment, a content application manager (CAM) process is used to provide one or more centralized redirection functions for network client processes such as just-in-time (JIT) packagers and cloud digital video recorders (cDVRs). A local database accessible to the CAM is updated with “live” or other content storage locations within the network, and accordingly each of the client processes can be made simpler and not require any intrinsic knowledge of content asset storage locations. This simplifies the client process configuration, enhances performance in terms of reduced end-user request servicing latency, and allows for single-point automated database updates versus having to provide updates to each client process as under the prior art.

摘要： Apparatus and methods to manage recording of streaming packetized content (such as for example live IP packetized content) for access, retrieval and delivering thereof to one or more users. In one embodiment, the foregoing is accomplished via communication between a recording manager and a receiver/decoder device. The recording manager manages and schedules recording of content on behalf of the receiver/decoder device (and/or mobile devices) disposed at a user's premises. The recording manager runs one or more computer programs designed to receive requests to record packetized content from one or more consumer devices, and use metadata contained within the requests to cause a cloud storage entity or premises storage device to record the content at its scheduled date/time (either via the receiver/decoder device itself, or another network entity). In this manner, the recording manager provides digital video recording (DVR) functionality to devices that would be otherwise incapable of scheduling a recording and/or recording such content.

摘要： Systems and methods for recording programs using a user's equipment and a network recording device are provided. An interactive television application may determine whether the user's equipment has sufficient resources (e.g., tuners or space) to record a program selected for recording. If the interactive television application determines that the user's equipment does not have sufficient resources, the interactive television application may select, automatically or in response to a user instruction, the program for recording with a network recording device. In some embodiments, the user may have to pay for the use of the network recording device, or may be required to purchase a given tier level of service. The interactive television application may play back programs from the network recording device as VOD offerings, or may direct the network recording device to transfer recorded programs to the user's equipment when it has sufficient resources.

摘要： Methods and apparatus for selectively enforcing required insertion or viewing of secondary content, such as advertisements or promotions, in a content distribution network. In one embodiment, the network is a managed network (e.g., cable television, satellite, or the like), and the method includes identifying secondary content with a particular attribute or property (e.g., an advertisement that a user has watched before), and selectively enabling one or more “trick mode” functions relating to that secondary content. In one implementation, audio codes or watermarks are inserted into the secondary content and detected when the content is accessed or rendered; if the detected content matches a database or listing of previously played content for that user or premises, the trick mode functionality (e.g., FF or “skip”) is enabled, thereby allowing the user to bypass the content.
