Abstract: A method of presenting program content to a user moving in a multiple zone home entertainment system using a wireless home entertainment hub comprises causing program content to be presented to a user using a first set of sink devices in a first zone, where each sink device of the first set of sink devices is registered with the wireless home entertainment hub. An indication that the user is in a second zone of the home entertainment system is received. The program content is caused to be presented to the user using a second set of sink devices in the second zone, where each sink device of the second set of sink devices is registered with the wireless home entertainment hub.

Abstract: A method and system for detection of video segments in compressed digital video streams is presented. The compressed digital video stream is examine to determine synchronization points, and the compressed video signal is analyzed following detection of the synchronization points to create video fingerprints that are subsequently compared against a library of stored fingerprints.

Abstract: A Radio Frequency Identification (RFID) system that tracks tags in real-time based on EPC codes and on other priority codes written into transponder memory fields of the tags. As an example, a priority code may be written into a memory of an RFID transponder identifying a high-value item or a small high-value item that is likely to be stolen. Based on the use of this priority code, those items can be preferentially tracked as opposed to items of low value or size such that they are unlikely to be stolen. Such use of priority codes and local filtering alleviates the need to go back to large centralized databases associating unique numbers with other parameters and potentially the history of the item.

Abstract: A television signal substitution system that replaces known video segments such as advertisements with selected replacement advertisements. Fingerprint data of known advertisements can be stored in a fingerprint database. When new fingerprint data is available, the fingerprint data can be automatically or manually transmitted to subscribers. Various techniques can be used to identify advertisements based on the fingerprint data.

Abstract: In general, in one aspect, the disclosure describes a method for detecting a known video entity within a video stream. The method includes receiving a video stream and continually creating statistical parameterized representations for windows of the video stream. The statistical parameterized representation windows are continually compared to windows of a plurality of fingerprints. Each of the plurality of fingerprints includes associated statistical parameterized representations of a known video entity. A known video entity in the video stream is detected when a particular fingerprint of the plurality of fingerprints has at least a threshold level of similarity with the video stream.

Abstract: A method of managing a power state of devices in a home entertainment system using a wireless home entertainment hub comprises obtaining a registration of a plurality of devices, where the plurality of devices includes at least one sink device and at least one source device. A selection of one of the source devices is received for presentation of program content to a user in the home entertainment system. A subset of the at least one sink device is determined for presentation of the program content to the user based on the selection of the source device. Each sink device in the subset of the at least one sink device is ensured to be active.

Abstract: A method for controlling presentation of data through a wireless home entertainment hub in a home entertainment system includes obtaining a registration for one or more source devices and for one or more sink devices. An indication is received at the wireless home entertainment hub that at least one of the source devices has become active. An instruction is transmitted to the sink devices to receive data from the at least one active source device. An indication is transmitted to at least one active source device that at least one of the sink devices is ready to receive data.

Abstract: A method for controlling presentation of data through a wireless home entertainment hub in a home entertainment system includes obtaining a registration for a plurality of source devices and for one or more sink devices. A first indication that a first source device from the plurality of source devices has become active is received at the wireless home entertainment hub. A second indication that a second source device from the plurality of source devices has become active is received. A first instruction is transmitted to at least one of the sink devices to receive data from the first active source device. A second instruction is transmitted to at least one of the sink devices to receive data from the second active source device. A first indication is transmitted to the first active source that at least one sink device is ready to receive data, and a second indication is transmitted to the second active source that at least one sink device is ready to receive data.

Abstract: A method of presenting program data in a multiple zones of a home entertainment system using a wireless home entertainment hub includes obtaining a registration of a plurality of source devices and sink devices at the wireless home entertainment hub. An assignment of a zone corresponding to each sink device is stored. A first selection of a first source device and a first zone for presentation of a first set of program data from the first source device is received. The first set of program data from the first source device is received, and transmitted to the first subset of sink devices in the first zone for presentation to a user.

Abstract: A method of connecting a legacy device in a home entertainment system containing a wireless home entertainment hub utilizing a home theatre network interface box includes obtaining a registration with the wireless home entertainment hub for the home theatre network interface box. The home theatre network interface box is connected to the legacy device and the home theatre network interface device is identified at the wireless home entertainment hub according to the functionality of the legacy device. An instruction from the wireless home entertainment hub to transmit data produced by the legacy device to at least one sink device in the home entertainment system is received, where the legacy device is a source device. Representation of the data produced by the legacy device from the home theatre network interface box to the at least one sink device is transmitted.

Abstract: A method of registering a device with a wireless home entertainment hub in a home entertainment system includes broadcasting by a wireless home entertainment hub a request for a reply from at least one unregistered device.
