A method of directing content preparation for a 5G media streaming (5GMS) network performed by at least one processor implementing a 5GMS application provider, the method comprising creating a content preparation template, by the 5GMS application provider, wherein the content preparation template includes first information specifying instructions for content preparation, and second information specifying instructions for content output; establishing a first provisioning session with a 5GMS application function; transmitting the content preparation template to the 5GMS application function in the first provisioning session, wherein the 5GMS application function requests to allocate 5GMS content preparation resources and 5GMS content distribution resources; and receiving a first acknowledgement from the 5GMS application function, wherein the first acknowledgement indicates an allocation of at least one of content preparation resources and content distribution resources.

Systems and methods for real-time transmission of data streams are disclosed. A controller receives data representing selected stream parameters from a browser residing on a computing device. The controller transmits the received data to a video transmitting device. A transcoder receives a first data stream generated according to the selected stream parameters from the video transmitting device. The transcoder generates a second data stream from the first data stream, the second data stream formatted for browser display; and then transmits the second data stream to the browser. A user may remotely control the video transmitting device using the browser. A user may view data streams from multiple video transmitting devices using the browser.

Methods and systems for selecting and delivering content are provided. More particularly, content can be delivered to an output device from a user device through a device adaptor, such as an over-the-top (OTT) device. The OTT device or devices available to the user device are determined by a communication server. In particular, the OTT device or devices available to the user device are limited to those OTT devices associated with an output device in the user's room, or that the user is otherwise authorized to access.

Described embodiments include a system that includes a network interface and a processor. The processor is configured to identify, via the network interface, a state of congestion in a communication channel between a base station belonging to a cellular network and a client device, to calculate, responsively to the state of congestion, a maximum sustainable encoding bit rate (MSEBR) for a video that is being downloaded by the client device, from a server, via the communication channel, the video being encoded at a plurality of different predefined bit rates, and to inhibit the client device, in response to calculating the MSEBR, from downloading a segment of the video that is encoded at any one of the predefined bit rates that exceeds the MSEBR. Other embodiments are also described.

Methods, apparatuses, and systems for improving utilization of a communications system (e.g., a satellite communications system) are provided, using delayed reliability techniques as part of a multicast transport protocol. Embodiments may operate in a client-server context, in which the server-side of the communication link multicasts data to requesting users and to users where the data is being speculatively prepositioned. Requesting users may implement reliability checks to verify receipt of complete data in response to the request while user systems where data is being speculatively prepositioned may receive multicast reliability information in response to reliability requests from other users, but may not request replacement of missing or corrupted data themselves until a request is made for the data by that system.

Methods and systems for a content server to select sets of video streams having different encoding parameters for transmitting the sets of video streams to a media device are disclosed herein. In some embodiments, a method for transmitting video streams for a media program from a server to a media device includes: selecting, by the server, first encoding parameters including a first bitrate for a first set of video streams for the media program based on a first estimated bandwidth capacity for a network linking the server and the media device, transmitting the first set of video streams from the server to the media device, determining, by the server, second encoding parameters including a second bitrate for a second set of video streams for the media program, and transmitting the second set of video streams from the server to the media device.
