    摘要： A method including: ingesting a video segment and a set of video features of the video segment; estimating a part size distribution for the video segment based on the set of video features and a first rendition of the video segment; calculating a maximum expected part size based on a threshold percentile in the part size distribution; at a first time, transmitting, to an video player, a manifest file indicating a set of byterange-addressable parts of the video segment in the first rendition, each byterange addressed part characterized by the maximum expected part size; at a second time, receiving, a playback request for a first byterange-addressable part; transcoding the first byterange-addressable part; in response to the maximum expected part size exceeding a size of the first byterange-addressable part in the first rendition, appending padding data to the first byterange-addressable part; and transmitting the first byterange-addressable part to the AV player.

    摘要： A system and method of operating an over-the-air broadcast television system having spectrum capacity that has a first portion for linear broadcasting content in real time and a second portion corresponding to a dormant capacity. A content distribution network system receives digital content from a content storage system. A dormant capacity estimator estimates dormant capacity of the spectrum capacity. An intermediate storage device communicates a registration request signal to the content distribution network system using a reverse link. The content distribution network system communicates a registration acknowledgement signal to the intermediate storage device. The content distribution network system communicates the digital content to the intermediate storage device through the over-the-air broadcast television network system. The intermediate storage device stories the digital content therein. The content distribution network system communicates the digital content to a user device through a local link after storing the digital content.

    摘要： Methods and systems of narrowcasting to a service group having one or more one-way set top boxes are shown and disclosed. The method may include receiving encrypted single program transport streams (SPTSs) from an encryptor, and receiving one or more session control signals for the SPTSs from a switched digital video (SDV) control system. The method may additionally include receiving service information (SI) packet identifiers (PIDs) for the SPTSs from a conditional access (CA) system, and updating the SI PIDs based on the one or more session control signals. The method may further include converting the SPTSs to narrowcast multiprogram transport streams (MPTSs) based on the one or more session control signals, and transmitting the narrowcast MPTSs and the updated SI PIDs to a plurality of edge quadrature amplitude modulation (QAM) devices.

    摘要： Methods and apparatus for enhancing connectivity for a device backhauled by a wireline communication network. In one embodiment, the device comprises a small-cell or other wireless base station that is backhauled by a DOCSIS system within a managed HFC network, and the method and apparatus enable enhanced connection of user devices serviced by the base station (such as 3GPP UE or CBRS FWA) to a core entity for e.g., authentication and packet session establishment. In one implementation, enhanced Cable Termination System (CMTS) and cable modem (CM) devices coordinate to allocate prioritized service flows to traffic sourced from the base station. These service flows can selectively bypass extant DOCSIS protocols which might otherwise increase connection latency (including connection failure) such as AQM (active queue management) and packet dropping algorithms. In some variants, upstream service flow data rates can also be enhanced through temporary utilization of higher-order modulation and/or coding schemes.
