摘要： Systems, methods, and devices for generating a constant bitrate (CBR) transport stream in manners that facilitate subsequent reconstruction, and for performing such reconstruction are disclosed herein. For example, generating a CBR transport stream may include for each payload packets: sampling a clock source to obtain a clock sample; and inserting an encoding of the clock sample in a stuffing area of a header of the payload packet. For example, reconstructing a CBR transport stream may include receiving a plurality of packets of a variable bitrate (VBR) transport stream; for a pair of adjacent packets in the VBR transport stream: extracting a clock sample from a header of each of the pair adjacent packets; computing a delta between the clock samples; and inserting one or more null packets between the adjacent packets based on the computed delta and a timing metric corresponding to a bitrate of the CBR transport stream.

摘要： Techniques are disclosed for initiating transient sessions on a communal device. An example method includes a system receiving, from a media streaming device, a request for a transient session token for initiating a transient session of a streaming service. The system can transmit, to the media streaming device, an authentication request for authenticating a user account that is associated with the streaming service. The authentication request can be transmitted based at least in part on the receipt of the request for the transient session token. The system can receive, from the media streaming device, an authentication response based at least in part on transmitting the authentication request. The system can authenticate that the user account is associated with the streaming service based at least in part on receiving the authentication response. The system can transmit the transient session token to the media streaming device. The transient session token comprises an expiration parameter for ending the transient session of the streaming service.

摘要： The present invention relates to a method for controlling the streaming of multimedia data in a network. The method comprising receiving, from a client device by a server, a request to control reception of at least one media stream from amongst a plurality of media streams as present in multimedia-data undergoing streaming by the client device, analysing the contents of the request to identify at least one of: a reception control message; the at least one media selected; and a type of control to be performed with respect to the at least one media, and responding the client device based on said analysis of the request by suspending or resuming the streaming of the at least one media stream from amongst the plurality of media streams in the multimedia data.

摘要： Systems maintain synchronicity among elements intended to be displayed at various points during a live media stream. At a multimedia player, start playback of a live media stream. The systems receive input from a user selecting a new time of the media stream to playback, which is different than the current playback time of the media stream. The systems adjust playback of the media stream to restart at the new selected time, such that the current playback time of the output media stream is updated to the new selected time. The systems monitor the current playback time of the media stream as adjusted. The systems determine a user-initiated command to execute for displaying one or more visual elements at the multimedia player by polling a command manifest file based on the current playback time as adjusted.

摘要： Synergistic queue management techniques are disclosed. The techniques can include receiving, by a server, a first queue action message, the first queue action message indicating a first queue action for a content queue associated with a client device, determining, based on the first queue action, a second queue action for the content queue, the second queue action comprising a supplemental queue action for the first queue action, and sending a second queue action message to the client device, the second queue action message indicating the second queue action.

摘要： Techniques are disclosed for initiating transient sessions on a communal device. An example method includes a device detecting a user device within a threshold distance of the device. The device can transmit control instructions to the user device for a response from the user device based on the detection, the response comprising an indication as to whether to initiate a transient session of a streaming service. The device can transmit, to an application server, a request for a transient session token based on the response from the user device. The device can receive, from the application server, the transient session token, the transient session token including an expiration parameter. The device can initiate the transient session based on the transient session token, the transient session comprising presenting content provided by the application server on a presentation device. The device can terminate the transient session based on the expiration parameter.
