摘要:
Systems, methods, and devices for an interactive viewing experience by detecting on-screen data are disclosed. One or more frames of video data are analyzed to detect regions in the visual video content that contain text. A character recognition operation can be performed on the regions to generate textual data. Based on the textual data and the regions, a graphical user interface (GUI) definition to can be generated. The GUI definition can be used to generate a corresponding GUI superimposed onto the visual video content to present users with controls and functionality with which to interact with the text or enhance the video content. Context metadata can be determined from external sources or by analyzing the continuity of audio and visual aspects of the video data. The context metadata can then be used to improve the character recognition or inform the generation of the GUI.

In one embodiment, a method includes determining focus on a focus item associated with a controllable item. The focus item is displayed on an interface that includes a plurality of display positions. A context for the controllable item based on the focus being on the focus item and a set of controllable attributes associated with the controllable item are determined. The method dynamically determines an order of the set of controllable attributes based on the context. The context is used to prioritize the set of controllable attributes in the order. The set of controllable attributes is displayed in the order in at least a portion of the plurality of display positions.

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.

A method of processing time-based content includes streaming the time-based content to a receiving device in a normal mode, evaluating a numerical difference between a program clock reference timestamp and a decode timestamp in the content at a transition out of said normal mode, streaming the content to the receiving device in a trick play mode, and altering the content during the trick play mode such that a numerical difference between the timestamps at a transition back into the normal mode is substantially equal to the numerical difference between the timestamps at the transition out of said normal mode.

Disclosed are methods and apparatus for correlating metadata from a plurality of different sources. The methods and apparatus may use an order for the data sources. The metadata from each of the data sources may be divided or split into one or more chunks. The metadata from each of the chunks may be filtered and sorted, e.g., to ensure that the metadata relate to the same multimedia content. The metadata chunks from the first data source in the order and the second data source in the order may then be aligned to produce currently aligned metadata. The metadata data chunks from the next data source in the order may then be aligned with the currently aligned metadata to produce new currently aligned metadata. This process may be repeated until the metadata from all of the sources are aligned, thereby providing a set of correlated metadata.
摘要:
One or more overlay wavelengths are applied to a GPON architecture to provide sufficient, cost-effective forward bandwidth per home for targeted, unique narrowcast services to allow traditional HFC operators to use a PON architecture with their existing HFC equipment. A separate return path capability using a separate coaxial cable with RF signals to the GPON may also be used. This return capability may be provided either by a fiber optic link or coaxial link from the home.

A switched digital video (SDV) system is provided which includes a SDV manager for coordinating SDV sessions requested by a plurality of subscriber terminals associated with a service group. The system also includes an input for receiving SDV programming to be broadcast during the SDV sessions. At least one edge device is provided for receiving SDV programming provided by the input and for transmitting each SDV program over an access network to at least one of the subscriber terminals on one of a plurality of SDV channels. The SDV manager is configured to (i) cause transmission of at least a first requested SDV program to be delayed until a later time; and (ii) select the first requested SDV program to be delayed from among a plurality of requested SDV programs based at least in part on a current viewing and recording status of the plurality of subscriber terminals.
摘要:
A method and apparatus for updating equalization coefficients of an adaptive pre-equalizer of a network element are provided. The method includes monitoring a communications channel to measure distortion of a communications signal received from the network element and detecting whether a transient impairment is present in the communication signal. When a transient impairment is not detected to be present, a pre-equalization coefficient update is transmitted to the network element. However, when a transient impairment is detected to be present, at least selected ones of the pre-equalization coefficients are scaled before the update is transmitted to the network element or the update is withheld from being transmitted to the network element. An apparatus is also disclosed.

Improved systems and methods for delivering CATV content over a fiber optic network from a transmitter. The transmitter preferably includes a combining network that combines CATV signals received from a CATV head end.
摘要:
A method of granting a client device remote access to a media server after receiving a remote access request at a remote access control server from a remote client device over a wide area network by receiving an opened port list at the remote access control server from the media server over the wide area network, the opened port list describing one or more wide area network ports opened at a residential gateway operating a local area network to which the media server is connected, and transmitting the opened port list and a network address of the residential gateway to the remote client device from the remote access control server, such that the remote client device can communicate with the media server on the local area network through the one or more wide area network ports opened at the residential gateway.
