A display apparatus transmits a picture acquisition request for getting picture information to an external image apparatus connected through a predetermined interface to the display apparatus from the external image apparatus at predetermined intervals and gets a plurality of pieces of picture information from the external image apparatus to be displayed. The plurality of pictures may be switched at predetermined intervals, for example, to be displayed, so that the plurality of pictures may be displayed in a so-called slide show manner. A plurality of pictures for thumbnail may be produced from the plurality of pieces of picture information and be arranged together to be displayed in one picture screen of a display device.

A reception apparatus including reception circuitry and processing circuitry is provided. The reception circuitry is configured to receive control information and content, the control information including resource sharing information indicating whether a resource is shared among a plurality of applications. The processing circuitry is configured to control, based on the resource sharing information, sharing of the resource among the plurality of applications. The resource sharing information includes an identifier that is associated with the plurality of applications among which the resource is shared. The resource includes at least one file associated with at least one of the plurality of applications.

A reception apparatus receives a content transmitted in an IP transmission system, acquires, based on first control information that is transmitted in a first layer in a protocol stack of the IP transmission system and includes information indicating whether second control information transmitted in a second layer higher than the first layer exists, the second control information, and controls operations of units that process the content based on the second control information.

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.

Aspects of the subject disclosure may include, for example, a local server coupled to a plurality of client devices. The local server may receive encrypted content from one or more content sources and provide the content to the client devices. The local server and client devices may be part of a multi-client environment such as a hotel or conference center. The local server does not decrypt and re-encrypt content, thereby allowing the use of low cost equipment. Other embodiments are disclosed.

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for providing over-the-air (OTA) content to electronic devices. Some embodiments operate by automatically providing program listings of OTA content to the electronic devices, wherein the program listings are displayed in user interfaces of the electronic devices; receiving a user selection of particular OTA content from one of the electronic devices; receiving electronic signals containing OTA content from an antenna; processing, using a tuner, the received electronic signals to extract the particular OTA content therefrom; and transmitting the extracted OTA content to the electronic device for playback. In some embodiments, the extracted OTA content is stored in storage of said the electronic device for future on-demand playback to the user.

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. When automatically switching 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, the current broadcaster application is notified and depending on the context, may continue executing or send data to the new broadcaster application.

A digital receiver for processing a broadcast signal includes a receiving module configured to receive the broadcast signal. Further, the broadcast signal includes service components of a broadcast service, service layer signaling (SLS) information for the broadcast service and a service list table for providing bootstrap information, and the service components include at least one of audio or video data. Further, the bootstrap information is different based on a type of delivery protocol of the SLS information, and the type of delivery protocol corresponds to either a Real-time Object delivery over Unidirectional Transport (ROUTE) protocol or a Moving Picture Experts Group (MPEG) Media Transport Protocol (MMTP). The digital receiver also includes a processor configured to process the service list table, the SLS information and the service components of the broadcast service.

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.

An example method of mapping a plurality of modulation symbols of a plurality of physical layer pipes present in a frame to a resource grid of data cells for the frame is described. The modulation symbols of the plurality of physical layer pipes are represented by a two-dimensional array comprising the modulation symbol values for the plurality of physical layer pipes and the resource grid of data cells is represented by a one-dimensional sequentially indexed array.
