Abstract
Embodiments of the present invention provide faster user-selected scene switching during playback of a video production. In one embodiment, several channels of video (e.g., several video streams each depicting a different camera angle) are read from interleaved data on a DVD disc. Each channel's data is maintained in a channel buffer that is input to a video decoder via a selector. When a signal from a user input device indicates that a user has selected a new channel, the selector can immediately provide the selected channel's data from the channel buffer to the video decoder, thus providing an increase in switching speed.
Claims28
A method for providing fast scene switching in a video playback device, wherein the video playback device includes one or more buffers coupled to a decoder via a selector, the method comprising
- obtaining two or more encoded video streams;
- storing the two or more encoded video streams into the one or more buffers;
- accepting a signal from a user input device to select a video stream;
- and
- using the selector to direct the selected video stream to the decoder.
An apparatus for providing fast scene switching, the apparatus comprising
- a video playback device, wherein the video playback device includes one or more buffers coupled to a decoder via a selector;
- an input for obtaining two or more encoded video streams;
- one or more instructions stored in a machine readable medium for storing the two or more encoded video streams into the one or more buffers;
- an input for receiving a signal from a user input device;
- and
- one or more instructions stored in a machine readable medium for using the selector to direct a selected video stream to the decoder, wherein the selected video stream is selected by the signal from the user input device to the decoder.
A method for providing fast scene switching in a video playback device, wherein the video playback device includes a buffer coupled to a decoder, the method comprising
- reading information from two or more interleaved video streams;
- determining which of the two or more interleaved video streams is a current stream;
- storing information for the determined stream into the buffer;
- and
- using the selector to direct the selected video stream information to the decoder.
