    摘要: Provided are a method of tuning a coding rate and applying an unequal error protection for an adaptive video transmission, and a video transmission/reception apparatus using the method. The video transmission apparatus may include: a coding rate tuner to predict, as a channel capacity of a subsequent channel interval, an estimated channel capacity value fed back from the video reception apparatus, and to tune video and channel coding rates within the predicted channel capacity; a video encoder to perform video encoding of video frames at the tuned video coding rate, and to generate a video packet; and a forward error correction (FEC) encoder to apply the unequal error protection based on a length of the video packet and a type of the video frames included in the video packet, and to perform channel encoding of the video packet at the tuned channel coding rate to generate a bitstream.

    摘要: Provided are a content writing apparatus and a content playback apparatus. The content writing apparatus may regard, as a single media file, a plurality of Moving Picture Experts Group (MPEG)-2 Transport Streams (TSs), may form a scene in a scene descriptor, such as a BInary Format for Scene (BIFS) or a Lightweight Application Scene Representation (LASeR), and may record the formed scene and the plurality of MPEG-2 TSs, as a media file in an International Standards Organization (ISO) format. The content playback apparatus may extract a scene from the media file in the ISO format, and may play back the extracted scene.

    摘要: A video encoding method and apparatus are provided. The video encoding method includes determining whether a current block includes an affine-transformation object having an affine transformation; if the current block includes an affine-transformation object, generating a prediction block by performing affine transformation-based motion compensation on the current block in consideration of an affine transformation of the affine-transformation object; and if the current block does not include any affine-transformation object, generating a prediction block by performing motion vector-based motion compensation on the current block using a motion vector of the current block. Therefore, it is possible to achieve high video encoding/decoding efficiency even when a block to be encoded or decoded includes an affine transformation.
