Comcast Corporation, formerly registered as Comcast Holdings, is an American mass media company and is the largest broadcasting and cable company in the world by revenue. It is the largest cable company and home Internet service provider in the United States, and the nation's third largest home telephone service provider. Comcast services U.S. residential and commercial customers in 40 states and the District of Columbia. The company is headquartered in Philadelphia, Pennsylvania.As the owner of the international media company NBCUniversal since 2011, Comcast is a producer of feature films and television programs intended for theatrical exhibition and over-the-air and cable television broadcast.Comcast operates multiple cable-only channels , and over-the-air national broadcast network channels , the film production studio Universal Pictures, and Universal Parks & Resorts, with a global total of nearly 200 family entertainment locations and attractions in the U.S. and several other countries including U.A.E., South Korea, Russia and China, with several new locations reportedly planned and being developed for future operation. Comcast also has significant holding in digital distribution . In February 2014 the company agreed to merge with Time Warner Cable in an equity swap deal worth $45.2 billion. Under the terms of the agreement Comcast is to acquire 100% of Time Warner Cable.Comcast has been criticized for various reasons. Comcast's customer satisfaction often ranks among the lowest in the cable industry. Comcast has violated net neutrality practices in the past; and, despite Comcast's commitment to a narrow definition of net neutrality, critics advocate a definition of which precludes distinction between Comcast's private network services and the rest of the Internet. Critics also point out a lack of competition; in the vast majority of Comcast's service area, it does not compete with other cable providers. Given Comcast's negotiating power as a large ISP, some suspect that Comcast could leverage paid peering agreements to unfairly influence end-user connection speeds. These issues, in addition to others, led to Comcast being dubbed "The Worst Company in America" by The Consumerist in 2014. Wikipedia.

Systems and methods are described for extending the trust relationship established with a network interface device that provides access to a service provider network that includes an IP-based overlay network. The trust relationship is extended to a consumer premises equipment (CPE) device operating on the overlay network. A network element of the service provider network may authenticate the CPE device when communicating via the overlay network. The service provider network may store an association between network configuration data of the network interface device and the CPE device provisioned via the network interface device and may provide the CPE device with an identity token that encodes this network configuration data. The CPE device may provide the identity token to a network element of the service provider network, and the service provider network may authenticate the identity of the CPE device using the identity token provided.

Methods and systems for managing data and/or operations on data such as content are provided. A method can comprise transmitting content to facilitate playback of the content. A trick play operation relating to the transmitted content can be detected. A threshold bandwidth can be determined based on normal playback of the content. A frame rate of the transmitted content can be adjusted during the trick play operation such that a bandwidth of the trick play operation is less than or equal to the determined threshold bandwidth.

Systems and methods are described herein for managing information transmitted between and/or within communication networks. Aspects discussed herein relate to monitoring and characterizing data flows with network and/or latency parameters, such as a time-to-buffer (TTB) parameter. Latency managers, network components, or other suitable devices operating in a communication network may utilize TTB parameter information as a management mechanism throughout the communication network to negotiate and schedule the delivery of data packets in view of a variety of factors, e.g., network performance, application priority, and the like. Such devices may be further configured to modify network or routing policies based on network performance and latency information obtained from and/or shared by various network components and devices in the communication network.


Methods and systems for intelligent use of off-peak bandwidth are disclosed. An example method can comprise receiving a request for content from a user device. The content server can transmit the content to the user device. Upon receiving a teardown command to suspend transmission of the content, after transmitting a first portion of the content to the user device, the content server can determine that playback of the content is likely to be resumed at a peak time. The content server can then pre-position a second portion of the content proximate to the user device prior to the peak time.

A media device and methods that identify playback states reachable from a current content playback state and identify a reachable state that is likely to occur, are disclosed. A memory associated with the media device may receive frames that enable a smooth transition between the playback state and the reachable state. The media device may receive frames that correspond to points in the content that are separated by an amount of time that is proportional to the playback rate of the likely state. The frames may be frames corresponding to an image that may be played back at the playback rate of the likely state.


Aspects of the disclosure are directed toward intelligently selecting the operating parameters of wireless access points (WAPs) deployed in a wireless environment so as to minimize or at least reduce interference in that wireless environment. A WAP continually measures the characteristics of the wireless channels used in the wireless environment and obtains measurements of channel metrics for those channels. The WAP stores the channel metric measurements as a channel metric history and analyzes the channel metric history to determine correlations between the channel metric measurements and various timeframes. The WAP selects one or more of its operating parameters based on the channel metric history and the correlations identified. Operating parameters include the radio frequency band and channel to transmit on. A centralized control server may also receive, store, and analyze channel metric histories from multiple WAPs and issue instructions to those WAPs identifying values for their respective operating parameters.

Methods and systems are disclosed for leveraging user premises supplied electric power to power active components in an information delivery network. In response to one or more conditions, an active component may switch an input power path from using grid-supplied or battery power to draw power from a user premises. The decision to switch the power path may be based on a number of conditions, for example, whether power is available from the grid, the relative cost of power from the user premises and whether the power from the user premises includes power from a renewable source.


Systems, methods, and devices for synchronizing playback of segmented video content across multiple video playback devices are described herein. In example implementations, a video server provides, to one or more playback devices, an age of a playlist for the video content. A particular playback device receives fragments of the video content from the video server and schedules the video fragments for playback. If the actual playback time of a video fragment is not aligned with its scheduled playback time, then video fragment is modified, e.g., by adding video frames to or removing video frames from the video fragment. Modification of the video fragments continues until the actual playback times of the video fragments synchronize with their respective scheduled playback times.
