A media device allows users to watch and capture portions from a media broadcast. Users may then share the captured media content items with other users, for example, by uploading the items to a community website. Before providing requested media content items to other users, the website may combine advertisements with the media content items. The website may receive advertising revenue from advertisers and may share the advertising revenue with owners of the media content items in exchange for their permission to provide the media content items. The advertisers may provide restrictions on how the advertisements are combined with the media content items, and the content owners may provide restrictions on how the media content items are provided to the users.

A media device allows users to watch and capture portions from a media stream. Users may then share the captured media content with other users. In one embodiment, the media device receives a media stream, plays the media stream, and caches a portion of the media stream as it is being played. A user can define a media clip by selecting its boundaries in the cached portion of the media stream. The media device creates the media clip based on the user's input and enables the user to transmit the media clip to another system, such as a community website for sharing it with other users.

A method for providing network access to a shared access communications medium for a plurality of users includes the steps of conducting predictive admission control by arbitrating user requests for access to the shared medium based on predicted aggregate demands, conducting lookahead scheduling for use in making user channel assignments by forecasting schedule transmission opportunities one or more channels of the shared medium, and balancing load by making channel assignments such that a plurality users are each assigned a respective channel of the shared medium based upon a predicted need. Congestion parameters can predicted for each channel of the shared medium and mapped to a congestion measure using a mathematical function that takes into account packet loss rate, packet delay, packet delay jitter, and available capacity.

A two-way cable network offering high-speed broadband communications delivered via virtual private networks over a multi-channel shared media system. Bi-directional transmission of packet to ATM cell based communications is established between a head end communication controller and a number of subscriber terminal units, whereby individual cells are prioritized and routed according to a virtual connection. Virtual connections are organized to support multiple virtual private networks in a shared media CATV system. The virtual private network to which a particular STU belongs is user selectable and has the flexibility of handling multi up/downstream channels with different MAC domains. The present invention can also handle non-ATM MAC domains via the same common ATM switch. To overcome the limited number of addresses inherent to common ATM switches, a mapping/remapping function is implemented in the port cards. Furthermore, downstream as well as upstream traffic are filtered at each STU. In one embodiment, information pertaining to downstream traffic is used to implement predictive scheduling in order to improve the timing associated with the request/grant cycle. In another embodiment, a user has the ability to select a quality of service that best suits the needs of the current application. In a further embodiment, the scheduling function is associated with each of the receivers in order to provide improved scalability.

Method enabling multiple communication nodes to access a transmission means on an electrical grid, which permits access in a fair manner by nodes on a shared medium such as the electrical network, achieving the maximum access speed when there are no collisions between reservation requests and the detection of coexistence signals in a robust way in noisy environments. It is characterized by the use of signals for reservation (5) and release (10) of the communication and by the random waiting prior to a reservation of the electrical network with minimum and maximum values fixed in advance.

A media clip is marked (156) in a wireless terminal (10) and transmitted further (164) to another wireless terminal (10) in which the marked media stream is received (182) and presented (194) according to the marking (156). A wireless network terminal (10) is shown applying the method, and a programmable means (14, 15, 16, 34, 35) usukkystrated in the wireless network terminal (10) to implement the method. A basis for marking (156) is a playhead position (23, 23a, 23b) which indicates progress of a media clip on a display (11) of the wireless terminal (10), and an end moment of the media clip when the media clip was stopped. This information is associated to playhead information which forms the basis for the marking (156) and reassemblying (184) a media data message (41) before sending it and after receiving it over a wireless network (50).

A computer-implemented method for automatically sharing media between users is provided. Collections of images are received from different users, where each collection is associated with a particular user and the users may be associated with each other. The collections are grouped into one or more albums based on the content of the images in the collection, where each album is associated with a particular user. The albums from the different users are grouped into one or more event groups based on the content of the albums. The event groups are then shared automatically, without user intervention, between the different users based on their associations with each other and their individual sharing preferences.

Systems and methods are provided for aggregating a local media collection of a user with one or more shared media collections shared with the user to provide an aggregate media collection for the user. In general, one or more shared media collections shared with the user are first discovered. Optionally, the user may select one or more of the shared media collections for aggregation with the local media collection of the user. The shared media collections selected by the user, or alternatively all of the shared media collections, are then aggregated with the local media collection of the user to provide an aggregate media collection for the user.

A method and apparatus for sharing media content between electronic equipment includes transferring session data from a first electronic equipment to a second electronic equipment, said session data including a queue of media content executing or executable on the first electronic equipment, and transferring media content identified in the session data to the second electronic equipment.

The present invention provides a technique for securely implementing port-based authentication on a shared media port in an intermediate node, such as a router. To that end, the invention provides enhanced port-based network access control that includes client-based control at the shared media port. Unlike previous implementations, the port does not permit multiple client nodes to access a trusted subnetwork as soon as a user at any one of those nodes is authenticated by the subnetwork. Instead, port-based authentication is performed for every client node that attempts to access the trusted subnetwork through the shared media port. As such, access to the trusted subnetwork is not compromised by unauthenticated client nodes that “piggy-back” over the shared media port after a user at another client node has been authenticated by the trusted subnetwork.

A novel and useful media access control (MAC) protocol that is intended for use over noisy shared media channels. The MAC protocol provides layer 2 functionality over a network using a shared medium including a backoff mechanism for CSMA/CA channel access, link addressing that reduces the overhead of long MAC addresses, a flooding scheme having controlled exposure for broadcast transmissions, multicast transmissions using selective ACKs, implementation of traffic prioritization using an adaptive backoff scheme, a second layer repeater establishment process and multi-packet transport for short packets and fragmentation for long packet transport.

According to the present application, systems, devices and methods for sharing media files may promote sharing of media without permitting the media to be downloaded. Such systems, devices and methods for sharing media may further enable lists of files to be shared and responses to be delivered to the media owner during playback by a user. A local device may be utilized to enable the storing and sharing of media that is hosted off the cloud. Streaming from the file sharing system or the local device is facilitated through the system.

At least one media device associated with the at least one subscriber is determined. The recording is sent to the at least one media device associated with the authorized subscriber.

Embodiments of the present invention provide users in a social network with a screen saver constructed by media shared by their contacts and groups in a social network. The present invention provides a shared photo album that displays images from a user's own photo collection, and that of their social network automatically. For a user, the social network service queries its database to retrieve a list of photo sources. The sources of images may be online photo sharing services, other computers with photos on their local hard drives, and public peer-to-peer storage services. The images may be displayed to the user and optionally may be accompanied with information, such as the owner of the photo or descriptive phrases or comments about the photo. The social network service may be configured to continuously or periodically request photos to update the screen saver.

System and method are disclosed for bridging a point-to-point network such as a Bluetooth scatternet with a shared medium network such as an Ethernet LAN. The scatternet is connected to the LAN via a network access point (NAP). Data packets sent from the LAN to the scatternet are filtered at the NAP to eliminate unnecessary data packets from being sent to the scatternet. Only certain ones of the data packets are forwarded between the LAN and the scatternet. An inter-NAP protocol is used to exchange messages where two or more NAPs are connected to the LAN. Broadcast loops are prevented from occurring in the scatternet and the LAN by defining Administrative domains and NAP service areas (NAPSAs), and controlling the borders thereof according to a broadcast type of the data packets.

The processing unit encoder/decoder can support one or more Pus. The network can be used, for example, in office, hospital, dense seat (e.g., aircraft, bus, etc.) and content provider networks.

Systems, methods, and devices for high efficiency wireless (HEW) access point (AP) coordination protocol are described herein. According to certain aspects, a method for coordinating access to a shared medium by an access point (AP) is provided. The method generally synchronizing with one or more peer apparatuses based on synchronization messages detected during a listening time, outputting, for transmission, scheduling information to the one or more peer apparatuses, the scheduling information indicating one or more time periods during which coordinated access to the shared medium is desired, and outputting, for transmission, at least some of the scheduling information to devices served by the apparatus.

An Ethernet architecture is provided for connecting a computer system or other network entity to a dedicated Ethernet network medium. The network interface enables the transmission and receipt of data by striping individual Ethernet frames across a plurality of logical channels and may thus operate at substantially the sum of the individual channel rates. Each channel may be conveyed by a separate conductor (e.g., in a bundle) or the channels may be carried simultaneously on a shared medium (e.g., an electrical or optical conductor that employs a form of multiplexing). On a sending station, a distributor within the sender's network interface receives Ethernet frames (e.g., from a MAC) and distributes frame bytes in a round-robin fashion on the plurality of channels. Each “mini-frame” is separately framed and encoded for transmission across its channel. On a receiving station, the receiver's network interface includes a collector for collecting the multiple mini-frames (e.g., after decoding) and reconstructing the frame's byte stream (e.g., for transfer to the receiver's MAC). The first and last bytes of each frame and mini-frame are marked for ease of recognition. Multiple unique idle symbols may be employed for transmission during inter-packet gaps to facilitate the collector's synchronization of the multiple channels and/or enhance error detection. A maximum channel skew is specified, and each received channel may be buffered with an elasticity that is proportional to the maximum skew so that significant propagation delay may be encountered between channels without disrupting communications.
