Abstract
Methods and systems for the efficient and non-redundant transmission of a single video program in multiple frame rates, optionally employing a combination of video coding standards, in a way that is backwards-compatible with legacy receivers only supportive of some subsection of frame rates or of some subsection of video coding standards.
Claims20
A method, comprising:
- receiving an encoded video stream corresponding to a program, wherein the encoded video stream includes a plurality of encoded pictures, wherein the encoding of the plurality of encoded pictures is according to a video coding specification;
- separating the plurality of encoded pictures into a first plurality of encoded pictures and a second plurality of encoded pictures;
- providing each encoded picture in the first plurality assigned to a first packet identifier value;
- and
- providing each encoded picture in the second plurality of encoded pictures assigned to a second packet identifier value, wherein the second packet identifier value is different than the first packet identifier value.

An apparatus, comprising:
- a memory;
- and
- one or more processors configured to:
- receive an encoded video stream corresponding to a program, wherein the encoded video stream includes a plurality of encoded pictures, wherein the encoding of the plurality of encoded pictures is according to a video coding specification;
- separate the plurality of encoded pictures into a first plurality of encoded pictures and a second plurality of encoded pictures;
- provide each encoded picture in the first plurality assigned to a first packet identifier value;
- and
- provide each encoded picture in the second plurality of encoded pictures assigned to a second packet identifier value, wherein the second packet identifier value is different than the first packet identifier value.
