    Abstract: A method, computing device and a computer-readable storage medium for encoding and decoding video data for streaming are provided. The method includes receiving video data comprising frames; accessing a dataset comprising at least one image expected to have similarity to at least one of the frames of the received video data; selecting an image or a portion of the image, from the dataset based on similarity to at least a portion of a first frame of the received video data; generating a frame using the image or the portion of the image selected from the dataset; encoding the generated frame and the frames of the received video data to produce encoded video data; and removing data corresponding to the generated frame from the encoded video data to produce modified encoded video data and generating data identifying the image or the portion of the image selected from the dataset.

    Abstract: A transmitting apparatus is provided. The transmitting apparatus includes: an encoder configured to generate a low-density parity check (LDPC) codeword by LDPC encoding of input bits based on a parity check matrix including information word bits and parity bits, the LDPC codeword including a plurality of bit groups each including a plurality of bits; an interleaver configured to interleave the LDPC codeword; and a modulator configured to map the interleaved LDPC codeword onto a modulation symbol, wherein the interleaver is further configured to interleave the LDPC codeword such that a bit included in a predetermined bit group from among the plurality of bit groups constituting the LDPC codeword onto a predetermined bit of the modulation symbol.

    Abstract translation: 提供发送装置。 发送装置包括：编码器，被配置为基于包括信息字比特和奇偶校验位的奇偶校验矩阵，通过输入比特的LDPC编码生成低密度奇偶校验（LDPC）码字，所述LDPC码字包括多个比特组 包括多个位; 配置为交织所述LDPC码字的交织器; 以及调制器，被配置为将交织的LDPC码字映射到调制符号，其中所述交织器还被配置为交织所述LDPC码字，使得包括在构成所述LDPC码字的所述多个比特组中的预定比特组中包括的比特到预定的 位的调制符号。
