Methods and systems for auto-zoom based adaptive video streaming

An apparatus comprising:

• a memory configured to store video data;
• and
• a processor configured to:
• output a first video stream the first video stream having a first resolution;
• receive input corresponding to selection of a location in a first video frame of the first video stream, wherein the input is associated with a request to zoom in on the location in the first video frame;
• determine a region of interest using the first video stream, the region of interest including an area around the location in the first video frame, wherein the region of interest is less than an entire area of the first video frame;
• identify a set of tiles of a second video stream, the set of tiles corresponding to the region of interest, the target the second video stream having a second resolution, wherein the second resolution is a higher resolution than the first resolution, and wherein the set of tiles include fewer than all tiles within video frames of the second video stream;
• enable receipt of sections of the video frames of the second video stream, the sections of the video frames including the set of tiles and excluding areas of the video frames outside of the set of tiles;
• enlarge the sections of the video frames according to a zoom factor;
• and
• output the enlarged sections of the video frames of the second video stream.

A non-transitory computer-readable medium having stored thereon instructions that when executed by a processor perform a method, comprising:

• outputting a first video stream the first video stream having a first resolution;
• receiving input corresponding to selection of a location in a first video frame of the first video stream, wherein the input is associated with a request to zoom in on the location in the first video frame;
• determining a region of interest using the first video stream, the region of interest including an area around the location in the first video frame, wherein the region of interest is less than an entire area of the first video frame;
• identifying a set of tiles of a second video stream, the set of tiles corresponding to the region of interest, the second video stream having a second resolution, wherein the second resolution is a higher resolution than the first resolution and wherein the set of tiles include fewer than all tiles within video frames of the second video stream;
• enabling receipt of sections of the video frames of the second video stream, the sections of the video frames including the set of tiles and excluding areas of the video frames outside of the set of tiles;
• enlarging the sections of the video frames according to a zoom factor;
• and
• outputting the enlarged sections of the video frames.
