Abstract
A method may include transmitting a video stream of a live scene over a network at a real-time transmission speed and detecting an event associated with the video stream being transmitted. The method may include transmitting the video stream over the network at a speed lower than the real-time transmission speed during the event. Transmitting the video stream at the speed lower than the real-time transmission speed may introduce a time stretch for the video stream to be played in slow motion. The method may include reducing a bitrate of the video stream after the event and transmitting the video stream with the reduced bitrate over the network after the event to compensate for the time stretch.
Claims20
A method comprising:
- transmitting a video stream of a live scene over a network at a real-time transmission speed;
- detecting an event associated with the video stream being transmitted, wherein the event has a start time and an end time in the video stream;
- transmitting the video stream over the network at a speed lower than the real-time transmission speed during the event, wherein transmitting the video stream at the speed lower than the real-time transmission speed introduces a time stretch for the video stream to be played in slow motion;
- and
- reducing a bitrate of the video stream after the event and transmitting the video stream with the reduced bitrate over the network after the event to compensate for the time stretch.
A device comprising:
- a transmitter to send a video stream of a live event over a network at a real-time transmission speed;
- and
- a processor to detect an event associated with the video stream being transmitted, wherein the event has a start time and an end time in the video stream;
- wherein the transmitter is configured to send the video stream over the network at a speed lower than the real-time transmission speed during the event, wherein when the video stream is transmitted at the speed lower than the real-time transmission speed a time stretch is introduced for the video stream to be played in slow motion, and
- wherein the processor is configured to reduce a bitrate of the video stream after the event and the transmitter is configured to send the video stream with the reduced bitrate over the network after the event to compensate for the time stretch.
