Embodiment Construction

[0037] The invention is shown by way of example and not limitation in the figures of the accompanying drawings, in which like reference numerals indicate similar elements. It should be noted that references to "an embodiment" or "one embodiment" or "some embodiments" in this disclosure are not necessarily to the same embodiments, and such references mean at least one embodiment.

[0038] According to various embodiments of the present invention, systems and methods may support bitstream switching in video streaming transmission. The system may divide each image frame in the sequence of image frames into a plurality of parts, wherein the plurality of parts includes at least a first part and a second part, may obtain a first set of encoded data of different encoding qualities for the first part, and may A second set of encoded data of different encoding quality is obtained for the second portion. Additionally, the system may determine a first switch point corresponding to a cha...

Abstract

A system and a method can support bit stream switching in video streaming. A distributed IDR picture transmission technique can be employed for reducing the delay, which is caused by the increase of amount of data to be transmitted, for performing bit stream switching. Additionally or alternatively, a progressive code stream switching technology can ensure smooth data stream transmission even when the bit stream switching happens.
