Control Information for a Wirelessly-Transmitted Data Stream
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.
Cellular communication protocol aware multimedia streaming
A device implementing cellular communication protocol aware multimedia streaming may include at least one processor configured to establish a link for communicating with another device, wherein the link utilizes at least one of a first cellular communication protocol or a second cellular communication protocol. The at least one processor may be configured to determine a bit rate for a video stream to be provided to the other device based at least in part on whether the link utilizes the first cellular communication protocol or the second cellular communication protocol, wherein a first bit rate is determined when the link utilizes the first cellular communication protocol and a second bit rate is determined when the link utilizes the second cellular communication protocol. The at least one processor may be configured to provide, for transmission over the link to the other electronic device, the video stream at the determined bit rate.
APPARATUS FOR TRANSMITTING BROADCAST SIGNALS, APPARATUS FOR RECEIVING BROADCAST SIGNALS, METHOD FOR TRANSMITTING BROADCAST SIGNALS AND METHOD FOR RECEIVING BROADCAST SIGNALS
The present invention provides an apparatus of transmitting broadcast signals, the apparatus including, an encoder for encoding service data, a frame builder for building at least one signal frame by mapping the encoded service data, a modulator for modulating data in the built at least one signal frame by an Orthogonal Frequency Division Multiplexing, OFDM, scheme and a transmitter for transmitting the broadcast signals having the modulated data.
DATA TRANSMISSION METHOD
Method for data transmission, in which an audiovisual media stream of a live (e.g., sporting) event, is transmitted by a first provider via the Internet and/or via at least one mobile radio network to a plurality of user terminals, and a data stream generated on the basis of the live event is made available by a second provider. The audiovisual media stream and the data stream are fed to a data preparation device, which generates a sequence of temporally spaced data packets and provides each data packet with identification information identifying the respective data packet and a time stamp. The generated data packets are synchronized with the media stream at controllable time intervals by the time stamp and sent via a bidirectional communication link by real-time transfer protocols and real-time streaming protocols to a group of user terminals for simultaneous playback synchronized with the audiovisual media stream.
METHODS FOR COORDINATING A MEDIA SESSION, RELATED NETWORK NODES, RELATED WIRELESS DEVICES, AND RELATED PRODUCTION DEVICES
Disclosed is a method which may be performed by a network node. The media session may be configured to be associated with an event. The production device is configured to receive, from the one or more wireless devices, media data for the media session. The method comprises coordinating the event; and transmitting, to the one or more wireless devices, control signalling indicative of a coordination parameter for coordinating the event.
Method and device for live-streaming with opportunistic mobile edge cloud offloading
A novel, pervasive approach to disseminating live streaming content combines secure distributed systems, WiFi multicast, erasure coding, source coding and opportunistic offloading using hyperlocal mobile edge clouds. The solution disclosed to the technical problem of disseminating live streaming content without requiring a substantial equipment, planning and deployment of appropriate network infrastructure points offers an 11 fold reduction on the infrastructural WiFi bandwidth usage without having to modify any existing software or firmware stacks while ensuring stream integrity, authorization and authentication.
APPARATUS AND METHOD FOR PROVIDING OFFLOADING SERVICE
Disclosed are an apparatus and method for providing an offloading service. A method of providing an offloading service according to an example embodiment includes streaming, to a user terminal including a cellular network receiver and a broadcast network receiver, media content data through a cellular network, transmitting, to the user terminal, an offloading service providing signal for activating the broadcast network receiver of the user terminal through the cellular network, transmitting, to the user terminal, a broadcast signal including connection information of a broadcast network to which the user terminal is to be connected so as to receive the media content data, through the cellular network, and broadcasting the media content data through the broadcast network.
ATSC BOUNDARY CONDITION FALL OVER TO INTERNET
Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. A receiver, to automatically switch from presenting a service on a first frequency to a second frequency such as when a mobile receiver is moving through a boundary region between two broadcasters, can temporarily use a satellite link or 5G wireless telephony or other over the top (OTT) source to acquire a service until an OTA link satisfies quality requirements.
Broadcast signal indicating one or more subframe configurations
A mobile station may comprise a receiver to receive, from a base station, a broadcast signal indicating a TDD configuration of uplink OFDM symbols and downlink OFDM symbols. The receiver may receive an indication of a symbol range and a subchannel range for use in transmission of CQI feedback. The mobile station may receive first downlink data and transmit first uplink data, using the TDD configuration, wherein the first uplink data comprises CQI feedback information transmitted in accordance with the symbol range and the subchannel range. The receiver may receive second downlink data, from the base station, on a different frequency as the first uplink data is transmitted, while the first uplink data is transmitted.
Media substitution task based on broadcast watermark
A radio receiver includes a tuner and processing circuitry, which in turn includes watermark detection circuitry and local playout control circuitry. The tuner receives an over-the-air radio broadcast on a tuned frequency. The over-the-air radio broadcast includes broadcast content. The processing circuitry, which is coupled to the tuner, is used to implement the watermark detection circuitry and local playout control circuitry. The watermark detection circuitry detects an actionable watermark included in the broadcast content, and transmits a watermark-detected signal to the local playout control circuitry in response to detecting the actionable watermark. In response to receiving the watermark-detected signal, the local playout control circuitry initiates retrieval of replacement content.
