The present disclosure disclose example video stream transmission methods and related devices and systems. One example method includes sending, by a client, a target request to a server, where the target request includes information about a corresponding target spatial location of a target spatial object that needs to be presented upon request by the client in a virtual reality VR content component. A target request feedback by which the server responds to the target request is received by the client, where the target request feedback includes information about a multiplex video stream that is obtained by performing preset multiplexing processing on an original video stream corresponding to the target spatial object. Video parsing and presentation based on the information about the multiplex video stream is performed by the client.

The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method, by which an increase in data size of signaling information transmitted by broadcasting can be suppressed. Provided is a reception apparatus including: a reception unit that receives a broadcast wave of digital broadcasting using an IP (Internet Protocol) transmission system; and a control unit that controls, on the basis of information for managing only a broadcast component transmitted by a broadcast wave of the digital broadcasting, which is first signaling information transmitted by a broadcast wave of the digital broadcasting, or information for managing at least one component of the broadcast component and a communication component transmitted by communication, which is second signaling information transmitted by communication, operations of respective units for acquiring the at least one component of the broadcast component and the communication component. The present technology is applicable to a television receiver, for example.

Provided is an encoding/transmitting apparatus used to transmit moving-picture data from a transmitting side to a receiving side and to subject the moving-picture data to streaming in the receiving side. The apparatus has an external-output request determining unit that monitors a state of a network. If the network assumes an undesirable state, a multiplex output unit stops multiplexing data. When the network assumes a good state, the multiplex output unit starts multiplexing the data again. A video encoding unit and an audio encoding unit keep encoding data, whether the multiplex output unit is multiplexing data or not. When the area occupied by encoded data in an encoded-video-data storage unit and the area occupied by encoded data in an encoded-audio-data storage unit exceed a predetermined value, the video encoding unit and audio encoding unit stop encoding data, and wait until the area occupied by encoded data sufficiently decreases.

Example techniques describe may facilitate a playback device applying a determined audio setting. An example implementation involves a first playback device receiving, over an unsecure network, a message indicating that a second playback device is available to join a playback network, wherein the first playback device is connected to the playback network. Based on a pre-existing configuration table, the first playback device determines an audio setting corresponding to a playback configuration for the second playback device, the playback configuration including the second playback device playing back audio synchronously with the first playback device in the playback network. The first playback device transmits, to the second playback device, one or more messages instructing the second playback device to apply the determined audio setting upon joining the playback network. Applying the determined audio setting includes forming the playback configuration with the first playback device to play back audio synchronously.

A method for generating an original total stream intended for being distributed to at least one broadcasting site, which includes a modulator and a transmitter sending a radiofrequency signal on a first frequency. The method implements the following acts: obtaining at least one transport stream comprising at least one transport packet; obtaining, from at least one modulation parameter for the broadcasting site, at least one starting instant of a modulation frame intended for being sent by the broadcasting site; inserting at least one modulation information packet in the at least one transport stream, at a position determined from the at least one starting instant; and generating the original total stream, including at least one physical layer pipe encapsulating the at least one transport stream carrying the at least one modulation information packet.
