115 results about "Pay-per-view" patented technology

Pay-per-view (PPV) is a type of pay television service by which a viewer can purchase events to view via private telecast. The broadcaster shows the event at the same time to everyone ordering it. Events can be purchased through a multichannel television platform using their electronic program guide, an automated telephone system, or through a live customer service representative. There has been an increasing number of pay-per-views distributed via streaming video online, either alongside or in lieu of carriage through television providers. In 2012, the popular video sharing service YouTube began to allow partners to host live PPV events on the platform.

Co-existing static and dynamic IP multicast

A system and method are provided for providing both static and dynamic IP multicasting. The concept of a multicast Static-Range is introduced which allows the coexistence of static and dynamic IP multicast. The multicast Static-Range is a set of Class D IP addresses which is reserved for static multicasting, and is configured at all routers. When a router receives a PIM message or an IGMP message, the router determines whether the group specified in the message is within the multicast Static-Range. If the group pertains to a static multicasting group, the router does not propagate the message to upstream routers using PIM-SM or PIM-SSM protocols, and only connects or disconnects interfaces internal to the router. If the multicast group address in the message is not within the multicast Static-Range, the router recognizes that the message pertains to a dynamic multicasting group and implements PIM or IGMP protocols as usual. If the invention is used for broadcasting TV, the low end of TB channels or commonly used channels can be created as static IP multicast. This way, a user can access or leave such channels without an entire shortest path tree being created or torn down, improving access time and channel surfing for a user. Also, pay-per-view, digital or less frequently used channels can be created using dynamic IP multicast with traditional PIM-SSM protocol, in order to make efficient use of router resources.

Multi-point multi-channel data distribution system

A system for the efficient distribution of live and stored audio / video streams to multiple subscribers without degrading normal data delivery services. The system segments one or more frequency bands into sub-bands, or channels, each of which is capable of carrying encoded audio, video, and other data streams, to a plurality of subscribers. Each channel transmitted in the system provides full-duplex operation so that each subscriber may indicate what specific services are desired, such as audio / video broadcast, two-way data transfer, video library access, pay-per-view video, interactive video, and audio file transfer. A transmission headend facility (‘hub’) broadcasts multiple channels of video / audio data (e.g., Internet data) in unicast mode via a shared media transmission facility to multiple subscribers. Simultaneously, selected video / audio / data is transmitted in Internet Protocol multicast mode over one or more channels of the segmented frequency band. The subscriber is provided a device which simultaneously and dynamically demodulates 2 or more channels and interleaves the information over a single ethernet interface connected to one or more IP enabled devices. Each subscriber thus has the capability of, for example, receiving a video stream concurrent with many other subscribers while simultaneously interacting uniquely with the Internet or other data network.

Methods and apparatus for protecting information

System, methods and apparatus are applicable to enable owners and vendors of software to protect their intellectual property and other rights in that software. The system also enables vendors or distributors of software to charge per-use for an instance of software. The system produces a unique, unforgeable, tag for every vendor supplied instance (copy) of specific software. Each user device is equipped with a supervising program that ensures, by use of the tag and other information, that no software instance will be used on the device in a manner infringing on the vendor, distributor, or software owner's rights. When installing or using a vendor-supplied software instance, the supervising program verifies the associated tag and stores the tag. When installing or using untagged software, the supervising program fingerprints selected portions of the software and stores the fingerprints. Software is used on a user's device through the supervising program which ensures proper use of the software. A vendor can submit a copy of infringing software to a guardian center which fingerprints appropriate portions of the infringing software. A user device's (104) supervising program periodically calls up, or can be called up, by the guardian center. During call-up, the supervising program can securely sends to the guardian center information about the use of the software instances associated with tags and fingerprints. The guardian center detects unauthorized use of software by comparison of current call-up data with records of past call-ups involving the same tags, and / or by comparing call-up supplied fingerprints with fingerprints of infringing software stored by the guardian center. The guardian center completes the call-up by enabling continued use of properly used software instances and generating appropriate punitive actions upon detection of improperly used software instances on the calling user's device. The data supplied by a supervising program during call-up is also employed by the guardian center to prepare data on usage by a user's device of vendor or distributor supplied software instances, for pay-per-use or pay-per-view billing.
