A geolocationing system and method for providing awareness in a multi-space environment, such as a hospitality environment or educational environment, are presented. In one embodiment of the geolocationing system, a vertical and horizontal array of gateway devices is provided. Each gateway device includes a gateway device identification providing an accurately-known fixed location within the multi-space environment. Each gateway device includes a wireless transceiver that receives a beacon signal from a proximate wireless-enabled personal locator device. The gateway devices, in turn, send gateway signals to a server, which determines an estimated location of the wireless-enabled personal locator device.

A computer-implemented system is provided that includes instructions that, when executed by at least one processor, cause the at least one processor to perform operations for transporting data over content delivery networks, the operations comprising: segmenting a data stream into a plurality of segments, where a segment may include at least one packet; generating a manifest file containing information associated with one or more segments in the plurality of segments, receiving a request for the manifest file, transmitting the manifest file to a receiver through a content delivery network, receiving a request for a segment in the manifest file, and transmitting the requested segment to the receiver through the content delivery network.

Display timing control of subtitles is to be excellently performed on a reception side. A video stream having coded image data is generated. A subtitle stream having text information on the subtitles and display timing information is generated. A transport stream containing the video stream and the subtitle stream is transmitted. For example, the display timing information on the subtitles contains information on display start timing and display duration.

A technique capable of allowing a reception side to easily select components is provided. A transport stream in which a first transport packet including predetermined components and a second transport packet including signaling information related to the predetermined components are time-division multiplexed is transmitted via a predetermined transport path. Component selection information is inserted in the second transport packet. The component selection information includes information on a selective layer in which static selection is performed, information on a composite layer in which composition is performed, and information on an adaptive layer in which dynamic switching is performed, and these layers being arranged in that order from top to bottom. The acquisition destination information of a component which is a target of adaptive switching among the components selectable in the adaptive layer is information that designates specific information location of a metafile having data stream acquisition information for adaptive streaming.

Control information for configuring an audiovisual device to present multimedia content according to a first service type may be generated. A method may include generating first control information for configuring an audiovisual device to decode a multimedia stream, generating first data that indicates a structure of the first control information, and transmitting the first data and the first control information. The first control information may be generated according to a first protocol version. Second data and second control information may be similarly generated and transmitted according to a second protocol version. Disclosed techniques may facilitate receiving devices to determine whether they support received wireless transmissions and decode the transmissions based on the control information.

A transmission device is disclosed. The transmission device comprises a signal generation unit for generating a broadcast signal including a service, and a transmission unit for transmitting the broadcast signal through at least one radio frequency (RF) channel. A broadcast stream transmitted through the RF channel includes signaling for the service, the signaling for the service including information indicating whether the service is transmitted through a plurality of RF channels, and information indicating whether the broadcast stream transmitted through the RF channel contains an essential portion of the service.

System, device, and method for transmitting a video via a User Datagram Protocol (UDP) over Internet Protocol (IP) communication link. A method includes: generating by a video encoder a set of N packets of compressed data per each frame of the video, wherein N is a natural number; and upon generation of each set of N packets for a specific frame of that video, immediately performing the transmitting of the set of N packets that corresponds to a single encoded video frame, via that UDP over IP communication link, without waiting for encoding or packetization of any other video frame of that video. Each packet of that video frame includes at least: a Coarse video data packet-portion, and a Fine video data packet-portion, and optionally also a Header packet-portion that includes sub-frames mapping information.

Method and apparatus for generation of interactive programming. An interactive programming server embeds interactive components into a video signal. The interactive programming server receives content from a content source and interactive components from an interactive component source and uses the content and interactive components to generate an interactive Video On Demand (iVOD) interactive program. The iVOD interactive program is transmitted to a participant who views the content and interacts with the interactive components of the iVOD interactive program. The participant's responses to the content is transmitted back to the interactive programming server where the participant responses are incorporated into new content which is used to generate new iVOD interactive programming.
