HIGH FRAME RATE-LOW FRAME RATE TRANSMISSION TECHNIQUE
A method for transmitting video content segments includes providing Low Frame Rate (LFR) and High Frame Rate (HFR) encoding mode designations for video content segments having static scenes and scenes with motion, respectively. Each video content segment is encoded accordance with its encoding mode designation and then transmitted with its encoding mode designation to enable retrieval and decoding by a decoder. Encoded video content appears as LFR content for processing as LFR content by equipment unaware of the present encoding.

providing Low Frame Rate (LFR) and High Frame Rate (HFR) encoding mode designations for video content segments having static scenes and scenes with motion, respectively;
encoding each video content segment in accordance with its encoding mode designation, wherein a video content segment with a HFR encoding mode designation comprises a sequence of HFR images, said sequence of HFR images being grouped into a plurality of sub-sequences of HFR images, each sub-sequence comprising a set of consecutive ordered HFR images of said sequence of HFR images, said video content segment having a HFR encoding mode designation being encoded by encapsulating a plurality of HFR images into a LFR image block in such a way that the HFR images having a same order in each sub-sequence being packed in a same LFR image block and that HFR images of a same sub-sequence map to a same quadrant of LFR image blocks; and
transmitting the encoded video content with its encoding mode designations to enable retrieval and decoding by a decoder.
