摘要： A method and apparatus for streaming Over-the-Top (OTT) content on a network to subscribers is described. A digital video transport stream of an item of the OTT content is obtained via unicast streaming methods of a resolution and bit rate selected from an available set of different resolutions and bit rates for the digital video transport stream. The digital video transport stream of the selected resolution and bit rate is transmitted in the form of an IP multicast over the network to subscribers. Bandwidth utilization of the network is monitored so that switching of the bit rate to a different bit rate for the digital video transport stream can be controlled to provide adaptive rate control of the IP multicast.

摘要： A video content delivery system is provided for set top boxes (STBs) that may be relocated as well as mobile clients using the Internet to retrieve content manifest files pertaining to the geographic area in which they are located. To provide this system, the edge cache in each geo-location region of a content provider is configured to append location specific metadata to a client's original HTTP request for content, making the request geo-location or region specific. The specific metadata appended by the edge cache in each region prevent clients from bypassing blackout or other content restrictions by moving from a non-restricted area and sending inaccurate location information. In another feature of the system to prevent client bypassing of blackout restrictions, the edge cache when communicating with the STB removes any location specific information which the client provides.
摘要翻译：为可以重定位的机顶盒（STB）以及使用因特网的移动客户端提供视频内容传送系统来检索与它们所位于的地理区域有关的内容清单文件。为了提供该系统，内容提供商的每个地理位置区域中的边缘高速缓存被配置为将位置特定元数据附加到客户端对于内容的原始HTTP请求，使请求地理位置或区域特定。每个区域中边缘缓存附加的特定元数据可防止客户端通过从非受限区域移动并发送不正确的位置信息来绕过中断或其他内容限制。在防止客户端绕过停电限制的系统的另一个特征中，与STB通信时的边缘缓存消除了客户端提供的任何位置特定信息。

摘要： A method and apparatus for providing seamless failover to a redundant stream at an edge device is disclosed. A plurality of identical streams are received via a plurality of paths at a plurality of synchronization buffers. Each synchronization buffer receives one of the plurality of identical streams from a corresponding path of the plurality of paths. The plurality of streams are synchronized. A composite stream is generated from the plurality of identical streams according to a packet selection process.

摘要： Method and apparatus for facilitating device redundancy in a fault tolerant system is described. One aspect of the invention relates to common redundancy for a set of devices in a redundancy group. Each of the devices is in either an active role or a standby role. Virtual configurations for the devices are stored in a management system. Advertisements are periodically sent from each of the devices in the active role to each of the devices in the redundancy group. Each of the advertisements includes a configuration sequence number. An update in one of the virtual configurations is announced by incrementing the configuration sequence number in at least one of the advertisements. An updated virtual configuration is obtained at each of the devices in the standby role from the management system in response to detecting the configuration sequence number as incremented in the at least one advertisement.

摘要： A system (10), method (90) and apparatus (14) are provided for provisioning a multicast stream, such as an IP multicast stream, in a network. The system includes a first tier (12), such as a national backbone, with a first Multicast Address Discovery (MCAD) directory (34), and at least one second tier having a headend, such as a regional headend (14), with a second MCAD directory (36, 38). The system (10) includes a tiered MCAD directory network that allows the assignment of multicast addresses to multicast streams received from an upper tier MCAD directory. The tiered MCAD directory structure allows for requesting and storing stream descriptors and delivering stream descriptors on-demand to MCAD-enabled devices throughout the system. The system (10) also allows for stream provisioning maintenance and validation at lower tier headends via MCAD-enabled device queries or re-queries of upper tier MCAD directories.

摘要： A system and method for efficiently adding a new network resource to a digital video network, without the need to purchase costly ancillary network hardware or extensive manual configuration, is disclosed. The inventive system and method provide for a loop-through for adding new resources to a digital video network. The present invention provides for the resources to be daisy chained from the network switch, where each resource is configured simply as either a loop-through (“LT”) resource or the “last” resource in the daisy chain. Then, only upstream traffic with Media Access Control (“MAC”) addresses of upstream LT resources are transmitted out of the loop-through by the last network resource.

摘要： A method of provisioning a set-top box (STB) with a provisioning server is disclosed. In the method, a provisioning request is received from a STB, where the provisioning request includes a provisioning stream identifier, an authorization server identifier, and a STB address. The provisioning server requests a provisioning system generate a configuration for the STB, where the configuration includes a channel map and basic code. The provisioning server receives the configuration from the provisioning system. The provisioning server prepares provisioning information, including the configuration for the STB and sends the provisioning information to the STB using the identifier for the STB.
