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. An ATSC3.0 service list table (SLT) contains correlations between service IDs and frequencies so that a receiver receiving duplicate services on different frequencies in a boundary between broadcast regions can select the best frequency to tune to in order to present the service, without having to access a database to correlate service IDs to frequencies.

The present invention proposes a method for providing a broadcast content in an apparatus, the method comprising: requesting a filter code to an application running on the apparatus by using a first Application Programming Interface (API); receiving a JavaScript Object Notation (JSON) object from the application in response to the first API; storing the filter code; receiving an Extended File Delivery Table (EFDT) having a first filter code associated with a first file; and selectively downloading the first file by comparing the stored filter code with the first filter code in the EFDT.

A method for multicasting multimedia content to receivers, the method comprising: receiving, by a multicast middleware (MCMF) from a server (BMS), manifest files to access contents according to different adaptive bitrate streaming communication protocols, one of the manifest files being consistent with the MPEG-DASH protocol and describing media segments of a content, another of the manifest files being a master playlist consistent with the HLS protocol and defining locations where media playlists to access the media segments of the content are available; receiving, by the middleware from the server, the media segments of the content, transmitted in a multicast session, receiving, by the middleware from the server, the playlists, the received playlists referencing the media segments transmitted in the multicast session, and currently received by the middleware; and storing by the middleware the manifest files, the media segments and the playlists, to make them available to receivers (UD, UD1, UD2).

This application provides a projection connection control method and an electronic device. The method includes: A transmit end device obtains preemption capability information from a receive end device, where the preemption capability information indicates whether the receive end device supports projection connection preemption; and when the receive end device supports projection connection preemption, the transmit end device sends first configuration information to the receive end device in response to a user instruction, so as to configure the receive end device to not support projection connection preemption.

Various embodiments are described herein for systems and methods that can be used to operate a media transmission network. In at least one embodiment, the media transmission network comprises a plurality of media processing devices configured to receive and process media streams based on control data. The media transmission network also comprises a controller coupled to the plurality of media processing devices and configured to generate a control signal for some or all of the media processing devices in the network. The controller is configured to determine the timing at which to transmit the control signal to a respective media processing device in order for the instructions in the control signal to be executed at the same time as the media data is received. The controller determines the transmission timing of each control signal by determining the latencies and delays of the network and the devices, such as, for example, network latency, processing delay, and/or control delay.

A broadcasting system that automatically generates broadcast transmission progress data generates and provides broadcast transmission progress data for real-time broadcast images including product information, discount information, and delivery information related to real-time broadcast images.

A media switch enables a terminal to access content by receiving a content request from a terminal for a first piece of content to be distributed over a cable system, identifying.sup., a personal channel within resources available in the cable system to distribute the first piece of content to the terminal, transmitting access information to the terminal to enable the terminal to access the first piece of content through the personal channel, and interfacing with a cable headend to provide the first piece of content on the personal channel.

A method for transmitting services information in a broadcasting network by at least one managing center towards a plurality of receivers includes exploring streams broadcasted by a DVB network and streams broadcasted by an IP network and extracting services information from these streams, completing an information table, situated at the highest level in a hierarchy of services information tables, included in the service information DVB-SI transmitted by the DVB network by services information related to the IP network, and transmitting the completed information table in the streams broadcasted by the DVB network towards the receivers having two switchable receiving modules, connected respectively to a DVB and an IP services broadcasting network. The receivers are able to activate the reception of digital data of a service, equivalent to the service currently received, with a second receiving module when receiving conditions of a first receiving module are degraded.

A production facility receives program content from a plurality of broadcast feeds over the Internet. In an embodiment, the production facility comprises server on a computer network, such as the Internet. The server comprises computer programs configured to manipulate the audio and video data of the multiple program contents. At the production facility, the program content can be manipulated to produce a production. Program manipulation can comprise at least one of green screen technology, music, graphics, Foley, sound effects, voice over, advertising, or the like. The production is broadcast over the computer network to viewers, where the viewers receive the production. In an embodiment, the production is customized based on the viewers' input received while broadcasting. In other words, the production is customized in real time based at least in part on the interaction of the production with the viewers. In another embodiment, the viewers can further manipulate the program content of the production to create a new production, which can be broadcast over the customized programming system.
