Abstract
Techniques are proposed for embedding transition points in media content. A transition point system retrieves a time marker associated with a point of interest in the media content. The transition point system identifies a first position within the media content corresponding to the point of interest. The transition point system embeds data associated with the time marker into the media content at a second position that is no later in time than the first position. The transition point system causes a client media player to transition from a first image quality level to a second quality level based on the time marker.
Claims20
A computer-implemented method to reduce noticeability of quality level changes during streaming of media content, based on transition points, the computer-implemented method comprising:
- providing a predefined set of values ranging from explicitly characterizing weakest candidacy as a transition point to explicitly characterizing strongest candidacy as a transition point;
- retrieving a time marker associated with a point of interest in the media content;
- identifying a first position within the media content corresponding to the point of interest;
- generating, by operation of one or more computer processors, a transition marker specifying a value that explicitly characterizes a candidacy of the point of interest as a transition point, wherein the specified value is selected from the predefined set of values, wherein the transition marker is embedded into the media content at a second position that is no later in time than the first position;
- and
- during streaming of the media content, causing a client media player to transition from an initial image quality level to a target image quality level at a point in time determined based on the transition marker, in order to reduce noticeability of the transition, wherein the target image quality level is determined based on a measure of available bandwidth.
A non-transitory computer-readable medium including instructions executable to perform an operation to reduce noticeability of quality level changes during streaming of media content, based on transition points, the operation comprising:
- providing a predefined set of values ranging from explicitly characterizing weakest candidacy as a transition point to explicitly characterizing strongest candidacy as a transition point;
- retrieving a time marker associated with a point of interest in the media content;
- identifying a first position within the media content corresponding to the point of interest;
- generating, by operation of one or more computer processors when executing the instructions, a transition marker specifying a value that explicitly characterizes a candidacy of the point of interest as a transition point, wherein the specified value is selected from the predefined set of values, wherein the transition marker is embedded into the media content at a second position that is no later in time than the first position;
- and
- during streaming of the media content, causing a client media player to transition from an initial image quality level to a target image quality level at a point in time determined based on the transition marker, in order to reduce noticeability of the transition, wherein the target image quality level is determined based on a measure of available bandwidth.
A computing system to reduce noticeability of quality level changes during streaming of media content, based on transition points, the computing system comprising:
- a memory that is configured to store instructions for a program;
- and
- a processor that is configured to execute the instructions for the program to perform an operation comprising:
- providing a predefined set of values ranging from explicitly characterizing weakest candidacy as a transition point to explicitly characterizing strongest candidacy as a transition point;
- retrieving a time marker associated with a point of interest in the media content;
- identifying a first position within the media content corresponding to the point of interest;
- generating a transition marker specifying a value that explicitly characterizes a candidacy of the point of interest as a transition point, wherein the specified value is selected from the predefined set of values, wherein the transition marker is embedded into the media content at a second position that is no later in time than the first position;
- and
- during streaming of the media content, causing a client media player to transition from an initial image quality level to a target image quality level at a point in time determined based on the transition marker, in order to reduce noticeability of the transition, wherein the target image quality level is determined based on a measure of available bandwidth.
