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 system for presenting live video content to a plurality of participant client devices is disclosed. An interactive program, including the live video content and an interactive component, is generated and a moderator interface is provided to enable a user of a moderator client device to create a look for the interactive program. The live video content and the interactive component are simultaneously displayed on a display of each of a plurality of participant client devices with the look created by the user of the moderator client device. The live video content and a response to the live video content are simultaneously displayed at each of the participant client devices with the look created by the user of the moderator client. The interactive program and the response are archived so that users of the plurality of participant devices may continue to interact with the interactive program after termination of the interactive program.

To enable satisfactory decoding processing corresponding to a decoding capability on a reception side. Image data of pictures constituting moving image data are sorted into multiple hierarchies, image data of pictures of each of the sorted hierarchies are encoded, and video data including the encoded image data of the pictures of each of the hierarchies is generated. A container of a predetermined format including the video data is transmitted. The multiple hierarchies are divided into a predetermined number of hierarchy groups, the predetermined number being two or more, and identification information for identifying a hierarchy group to which encoded image data of each picture included in the video data belongs is inserted into a packet as a container of the video data.

The present invention provides a method for transmitting a broadcasting signal. A method for transmitting a broadcasting signal according to the present invention suggests a system capable of supporting a next generation broadcasting service in an environment which supports a next generation hybrid broadcast using a terrestrial broadcast network and an internet network. Furthermore, in an environment which supports a next generation hybrid broadcast, suggested is an efficient signaling scheme which can embrace both a terrestrial broadcast network and an internet network.

Systems and methods for dynamically multiplexing requested linear media channels and network data on forward link traffic streams of a communication link to a craft media delivery system are provided. Furthermore, systems and methods for receiving dynamically multiplexed requested linear media channels and network data on forward link traffic streams of a communication link by a craft media delivery system are also provided.

An association with a system timing at the time of transmission is secured without changing a display timing in text information of a subtitle, and a reception side displays the subtitle at an appropriate timing. A packet in which a document of the text information of the subtitle having display timing information is included in a payload is generated and transmitted in synchronization with a sample period. A header of the packet includes a time stamp on a first time axis indicating a start time of the corresponding sample period. The payload of the packet further includes reference time information of a second time axis regarding the display timing associated with the start time of the corresponding sample period.

Disclosed is an electronic device that receives a packet of a content image including a plurality of frames from an external device, transmits a signal indicating whether a packet is received, including a request for a bit rate of an image in a transmitted signal, receives a packet with a changed bit rate of the image based on the request, and displays the image on the display based on the received packet.

The embodiment of the present disclosure provides a method and an apparatus for displaying a video image, an electronic device and a storage medium. The solution is as follows: receiving, by a server, a UDP request sent by a client based on an IP address of the server, wherein the UDP request includes identification information of a video to be played; acquiring the video to be played according to the identification information of the video to be played; encapsulating the video to be played from a key frame of the video to obtain a UDP packet; and sending the UDP packet to the client at a first transmission rate, so that the client, after receiving the UDP packet, decapsulates the UDP packet to obtain the video to be played, and display a first image frame of the video to be played, wherein the first transmission rate is the maximum transmission rate determined according to a network bandwidth. According to technical solutions provided in the embodiments of the present disclosure, the time required from initiating the request to displaying the first image frame of the video is reduced, and a display speed of the first image frame of the video is improved.

The present disclosure describes a monitoring device for determining one or more characteristics of one or more scheduled programs within one or more packetized elementary streams of one or more transport streams. The monitoring device receives the one or more transport streams from a service provider system and de-encapsulates the one or more packetized elementary streams from the one or more transport streams. The monitoring device determines the one or more characteristics of the one or more scheduled programs from the one or more packetized elementary streams. The one or more characteristics can be used by the monitoring device to adapt on a dynamic, real-time, or near real-time, basis to changes to the one or more transport streams.
