Disclosed are a hypertext transfer protocol (HTTP) request transmission method and device. The HTTP request transmission method and device resolve a problem that data finally obtained through splicing is invalid because dividing an original HTTP request into a plurality of HTTP requests to pull data from different content distribution network (CDN) servers may cause inconsistency of the pulled data. When an electronic device needs to download data from a plurality of CDN servers, an overlapping range may be designed for byte ranges allocated to the different CDN servers. This means that the electronic device downloads data in the overlapping range from all the different CDN servers. Therefore, this part of data is used to check consistency of the data pulled from the different CDN servers. When determining that the data pulled from the different CDN servers is consistent, the electronic device may splice the data to obtain finally required data.

Embodiments described herein relate to real-time streaming of large quantities of time critical data over multiple distinct networks from a communications device. More specifically, embodiments described herein may address challenges and problems of maintaining consistent data reception quality when faced with the anomalies of a moving sender that is sending data using a relatively unstable method. This may be achieved by converting single source data into multiple data streams, placing them in transport buffers and storing them for forwarding.

Concepts and technologies are disclosed herein for providing streaming video from mobile computing nodes. A request for streaming video captured by a mobile computing node can be received at a computer including a processor that executes a controller. The request can include a parameter associated with the streaming video. The computer can initiate transmission of an inquiry message to two or more mobile computing nodes and receive inquiry message responses from the mobile computing nodes that include the mobile computing node. The inquiry message responses can indicate that the mobile computing nodes can satisfy the parameter. The computer can create a list of the mobile computing nodes that can satisfy the parameter and provide the list to the requestor. The computer can receive a selection of the mobile computing node, and initiate delivery of a video stream to the requestor.

A method for transmitting a broadcast signal, includes compressing headers of Internet Protocol (IP) packets in an IP packet stream to output a compressed IP packet stream, the compressed IP packet stream including Initialization Refresh (IR) packets, a first group of IR-dynamic packets, and compressed IP packets; extracting context information from the compressed IP packet stream, wherein when the context information is extracted only from the IR packets in the compressed IP packet stream, the IR packets are converted to a second group of IR-dynamic packets; building signaling information including the context information; and encapsulating the signaling information into one or more signaling link layer packets and the compressed IP packet stream into link layer packets that are distinct from the one or more signaling link layer packets.

Implementations for combining at least two video streams received from devices of a plurality of participants of a video conference into a composite video stream are described. A video conference including the video streams received from the devices of the plurality of participants is established. A capability associated with consuming at least two of the video streams is received from at least one of the devices. The at least two video streams are then combined into a composite video stream based on the capability associated with consuming the at least two video streams. The composite video stream is transmitted to the at least one of the devices.

This application provides a multicast service transmission method and apparatus, to deliver a multicast service regardless of whether there is a device supporting multicast in a system, so as to improve flexibility and reliability of the multicast service transmission. The method performed by a session management network element includes: receiving a first message or a second message, where the first message requests to add a terminal device to a multicast service, the second message is used to update a PDU session of the terminal device, and the PDU session is associated with the multicast service; and determining, based on multicast capability information of the terminal device and/or multicast capability information of an access network device, a delivery mode of the multicast service, where the access network device is an access network device currently accessed by the terminal device or a target access network device of the terminal device.

The present invention refers to the field of television experience in particular the simultaneous use of the portable computing device and a television to share a user's experience. The present disclosure proposes a method to create a snapshot from a video transmission received by a receiver, said receiver being connected with a portable computing device and having a screen output, said method comprising the steps of receiving a video transmission by the receiver, converting by the receiver, the video transmission into a lower-bandwidth video transmission, sending the lower-bandwidth video transmission to the portable computing device, receiving from the portable computing device to the receiver, a command to execute a snapshot, producing by the receiver a snapshot from the video transmission, sending the snapshot to the portable computing device.

Systems and methods provide live broadcasts with real-time feedback from viewers using mobile computing devices. An example method includes providing a live feed broadcast from a source mobile device to a plurality of viewing devices, receiving, during the live feed broadcast, a plurality of feedback signals, each feedback signal being from at least one of the plurality of viewing devices, and associating each feedback signal with a respective time in the live feed broadcast. The method further includes providing, for each feedback signal in the plurality of feedback signals, an indication of the feedback signal to the source mobile device and to each viewing device of the plurality of viewing devices, the indication being used to display a symbol representing the feedback signal as an animation, the animation moving the symbol on a path during display and lasting for a predetermined time subsequent to the respective time.

A method, an apparatus and a system for the reproduction of a specific multimedia content are provided. The method includes the step of acquiring one or more samples of a specific multimedia content reproduced by a mobile multimedia radio/television apparatus, where the specific multimedia content is included in a first signal emitted by a broadcast-type radio/television network, including the further step of determining an identifier of the specific multimedia content and the value of a quality parameter of the first signal. According to the value of the quality parameter of the first signal, further steps include receiving on a multimedia telephone apparatus the specific multimedia content through a second signal emitted by a cellular telephone network, sending the specific multimedia content to one or more multimedia reproduction units included in the mobile multimedia radio/television apparatus.

A method for performing live-streaming of user-generated content over a media-streaming network, including transmitting, by a 5.sup.th generation media streaming (5GMS)-aware application, a live-streaming request corresponding to the user-generated content to a 5GMS application provider (AP); receiving, by the 5GMS-aware application, from the 5GMS AP, an edge application server (LAS) profile corresponding to the live-streaming request, wherein the EAS profile indicates a service class (SC) from among a plurality of SCs, the SC corresponding to the live-streaming request; selecting, by the 5GMS-aware application, a 5GMS application server (AS) based on the SC; and performing the live-streaming of the user-generated content over 5GMS network to the 5GMS AS according to the SC.
