Abstract
Provided is a method for reverse playback of encoded multimedia content, including receiving a request for the reverse playback of the encoded multimedia content from a user or an electronic device, identifying a first Intra frame (I-frame) from a first Group Of Pictures (GOP) constituting a portion of the encoded multimedia content and preceding a last played frame at an instant of receiving the request, decoding first successive frames in the first GOP starting from the first I-frame, storing the first decoded frames in a memory, and playing the first decoded frames in a frame sequence effecting the reverse playback.
Claims9
A method for reverse playback of encoded multimedia content, the method comprising:
- receiving a request for the reverse playback of the encoded multimedia content from a user or an electronic device;
- identifying a first Intra frame (I-frame) preceding a last played frame at an instant of receiving the request from a first Group Of Pictures (GOP) constituting a portion of the encoded multimedia content;
- decoding first successive frames in the first GOP starting from the first I-frame;
- storing the first decoded frames in a memory;
- and
- playing the first decoded frames in a frame sequence effecting the reverse playback.
An apparatus for reverse playback of encoded multimedia content, the apparatus comprising:
- a processor for identifying a first intra frame (I-frame) preceding a last played frame from a first group of pictures (GOP) constituting a first portion of the encoded multimedia content, at an instant of receiving a request for the reverse playback from a user or an electronic device, decoding first successive frames in the first GOP starting from the first I-frame, and playing the first decoded frames in a frame sequence effecting the reverse playback;
- and
- a memory for storing the first decoded frames.
A computer readable medium storing a program causing a processor to execute a process for data processing, the process comprising:
- receiving a request for reverse playback of encoded multimedia content from a user or an electronic device;
- identifying a first intra frame (I-frame) from a first group of pictures (GOP) preceding a last played frame at instant of receiving the request, wherein the first GOP constitute a portion of the encoded multimedia content;
- decoding first successive frames in the first GOP starting from the first I-frame;
- storing the first decoded frames in a memory;
- and
- playing the first decoded frames in a frame sequence effecting the reverse playback.
