In the DVC encoder, key frames are encoded by a conventional intra-frame encoding method such as H.264/AVC intra-frame mode.
The key frames are coded separately using a conventional intra codec, e.g., H.264/AVC intra [1] or Motion JPEG.b The Wyner-Ziv frames on the other hand are encoded in two stages.
After the dimensions of the original Wyner-Ziv frames have been reduced, the result is coded using a conventional intra video codec, exploiting spatial correlation within the hash frame only.
On the proposed decoder side, the key frames are reconstructed using a conventional H.264/AVC intra-frame decoder.
The first frame (named key-frame) of a (GOP) is encoded in a conventional intra frame way (e.g., JPEG).
Since each part has computation less than or similar to intra-frame coding, 2D-DVC's encoding complexity is similar to the conventional intra-frame model.
The first frame of each GOP, also referred to as key frame, is encoded using a conventional intraframe coding technique such as H.264/AVC in intraframe mode [1].
The conventional intra frame decoder first decodes the video stream from the encoder.
The functional block of the conventional intra frame encoder, such as H.263+, H.264/AVC, H.265/HEVC, MPEG-2 and MPEG-4 intra frame coding, and even JPEG, JPEG-2000, all depend on the range of suggestion.
The decoder consists of three main parts, including the conventional intra frame decoder, the block padding and the pixel padding, shown in the Fig. 7.
