摘要： The systems, methods, and devices of the various embodiments enable elastic response times to file requests by a server. In this manner, the server may account for unpredictable delay in object/segment availability and reduce the frequency that error messages (e.g., 404 error messages) are returned in response to file requests when file unavailability is temporary and due to network delays.

摘要： The present disclosure relates to a streaming media technology, and in particular, to a client device, a method for receiving a streaming media data and a streaming media data transmission system, which may solve the problem that the client device takes too much time to acquire the media content when the network condition between the client device and the server suddenly degrades. In the client according to the embodiments of the present disclosure, a transceiver module transmits a request for a segment to a server and receives the segment transmitted from the server; and if it is determined by a processing module that the transceiver module does not receive a first segment transmitted from the server within the preset threshold time from transmitting the request for the first segment to the server, the processing module controls the transceiver module to transmit a request for a second segment having the same media content and a lower bit rate to the server, so as to ensure that the client device can adjust the bit rate in time and can acquire the media content as quickly as possible, thereby ensuring a continuity of playing of the media content.

摘要： The present invention provides a multi-view video transmission method and apparatus. The method includes: obtaining a location of a viewpoint video to which a user currently pays attention in a multi-view video; obtaining a first speed at which a user viewpoint switches, where the first speed is a speed at which the user viewpoint switches to the location of the viewpoint video to which attention is currently paid; determining, according to the first speed and according to a preset algorithm, a quantity NNV of predictive viewpoint videos that need to be downloaded before the user switches to another viewpoint; determining locations of the predictive viewpoint videos in the multi-view video according to a preset rule and according to the location of the viewpoint video to which the user currently pays attention, the first speed, and the quantity NNV of the predictive viewpoint videos, where the predictive viewpoint videos are viewpoint videos whose probability of becoming a next viewpoint video attention is to be paid satisfies a preset probability value; and downloading the predictive viewpoint videos corresponding to the locations of the predictive viewpoint videos from a server end and transmitting the predictive viewpoint videos. A time delay caused during switching of an angle of view can be avoided. Moreover, not all viewpoint videos need to be transmitted, and therefore a waste of bandwidths is reduced.

摘要： Technologies for performing contextually adaptive media streaming are described. In some embodiments, the technologies utilize contextual parameters leverage contextual information to alter the parameters of a content stream that is provided to a client device from a server. In some embodiments, the parameters of the content stream are altered by changing one or more input parameters (e.g., a report of network parameters) that is/are operated on by adaptive logic of a media player on the client device. Alternatively or additionally, in some embodiments the technologies leverage contextual information to alter the manner in which a client device processes content in a received content stream for consumption. Systems, devices, and methods employing the technologies are also described.
