METHOD AND SYSTEM FOR PLAYBACK OF MOTION VIDEO

摘要

Playback of motion video is presented. A method may comprise requesting streaming of a specific motion video sequence from a storage device to a playback device, streaming motion video data of the requested motion video sequence, displaying the streamed motion video data as the streamed motion video data is received, and sending a request of change of playback speed to the data storage device. In response to the request, decoding, in the data storage device, motion video data from a temporal position in the specific motion video sequence that has not yet been streamed to the playback device, compressing, in respect of time, the decoded motion video data, encoding the compressed motion video data using an encoding scheme corresponding to an encoding scheme used to encode the specific motion video sequence, and continue streaming the motion video sequence to the playback device using the compressed and encoded motion video data.

主权项

1. A method for playback of motion video, the method comprising:
requesting, via a communication network, streaming of a specific motion video sequence from a motion video storage device to a motion video playback device; streaming motion video data of the requested motion video sequence from the motion video data storage device to the motion video playback device; displaying the streamed motion video data on a display connected to the playback device as the streamed motion video data is received at the playback device; sending a request of change of playback speed to the motion video data storage device; in response to receiving the request of change of playback speed at the motion video data storage device the following acts are performed:
decoding, in a decoder of the motion video data storage device, motion video data from a temporal position in the specific motion video sequence that has not yet been streamed to the motion video playback device;compressing, in respect of time, the decoded motion video dataencoding, in an encoder of the motion video data storage device, the compressed motion video data using an encoding scheme corresponding to an encoding scheme used to encode the specific motion video sequence; andcontinue streaming the motion video sequence to the motion video playback device using the compressed and encoded motion video data.
