Abstract
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.
Claims22
A method for transmitting video content segments, comprising:
- 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.

A method for processing received video content segments, comprising:
- determining for each received video content segment one of a Low Frame Rate (LFR) and a High Frame Rate (HFR) encoding mode designation for that received video content segment indicating whether that segment includes static scenes or scenes with motion, respectively;
- decoding 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 decoded by obtaining a plurality of HFR images from 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
- providing each decoded video content segment to a display device.

Apparatus, comprising:
- an encoder configured to (1) receive Low Frame Rate (LFR) and High Frame Rate (HFR) encoding mode designations for received video content segments having static scenes and scenes with motion, respectively;
- and (2) encode each video content segment in accordance with its encoding mode, 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.

Apparatus comprising,
- a decoder configured to (a) establish for each received encoded video content segment one of a Low Frame Rate (LFR) and a High Frame Rate (HFR) encoding mode designation depending on whether that received encoded video segment includes static scenes or scenes with motion, respectively, and (b) decode each received encoded 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 decoded by obtaining a plurality of HFR images from 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.
