Encoding and transmitting image frames of a video stream

A device configured for encoding and transmitting a plurality of image frames of a video stream, the device comprising:

• an encoder, comprising circuitry adapted to:
• encode the plurality of image frames using a periodic intra refresh encoding technique to produce intra refresh encoded image frames, used by a decoder to playback the plurality of image frames, and
• intra frame encode one image frame of the plurality of image frames into a plurality of data packets, used by the decoder to start playback of the plurality of image frames, wherein the intra frame encoded one image frame replaces a corresponding frame in the intra refresh encoded image frames, and
• a transmitter, comprising circuitry adapted to:
• transmit, during a first period of time, the intra refresh encoded image frames, and
• transmit the plurality of data packets, wherein at least some of the data packets are delayed such that the transmission of the plurality of data packets is distributed over the first period of time.

A method for storing an encoded video stream, the method comprising:

• receiving, during a first period of time, a plurality of encoded image frames being encoded using a periodic intra refresh encoding technique,
• receiving, distributed over the first period of time, a plurality of data packets, comprising an intra frame encoded image frame, the intra frame encoded image frame corresponding to one image frame of the plurality of encoded image frames,
• replacing the corresponding one image frame of the plurality of encoded image frames with the intra frame encoded image frame to form an encoded video stream, and
• storing the encoded video stream.

A device configured for storing an encoded video stream, comprising:

• a receiver comprising circuitry adapted to:
• receive, during a first period of time, a plurality of encoded image frames being encoded using a periodic intra refresh encoding technique, and
• receive, distributed over the first period of time, a plurality of data packets, comprising an intra frame encoded image frame, the intra frame encoded image frame corresponding to one image frame of the plurality of encoded image frames,
• a processing unit, comprising circuitry adapted to replace the corresponding one image frame of the plurality of encoded image frames with the intra frame encoded image frame to form an encoded video stream, and
• a storage medium adapted to store the encoded video stream.

A non-transitory computer-readable storage medium with instructions adapted to carry out a method for encoding and transmitting a plurality of image frames of a video stream when executed by a device having processing capability, the method comprising:

• encoding the plurality of image frames using a periodic intra refresh encoding technique to produce intra refresh encoded image frames, used by a decoder to playback the plurality of image frames;
• intra frame encoding one image frame of the plurality of image frames to produce intra frame encoded image data of the one image frame, used by the decoder to start playback of the plurality of image frames, wherein the intra frame encoded image data replaces a corresponding frame in the intra refresh encoded image frames;
• organizing the encoded image data in a plurality of data packets;
• transmitting, during a first period of time, the intra refresh encoded image frames;
• and
• transmitting the plurality of data packets, wherein at least some of the data packets are delayed such that the transmission of the plurality of data packets is distributed over the first period of time.
