Abstract

The present invention provides a video encoding device in which a capacity of a binary data storing unit is small, a size of the video encoding device is small, a video signal can be processed in real time, and reduction in quality of images generated from the eventually obtained data can be prevented. The video encoding device according to the present invention includes: a video encoding unit which encodes a video signal; a binarization unit which binarizes an encoded value obtained from the video encoding unit; and an entropy encoding unit which subjects entropy encoding to binary data obtained from the binarization unit. Here, the video encoding unit encodes the video signal based on a characteristic of the binarization performed by the binarization unit, so that an amount of binary data obtained from the binarization unit by binarizing the encoded value that is encoded based on the characteristic is less than an amount of binary data obtained by binarizing an encoded value that is encoded without being based on the characteristic.

Description

technical field [0001] The present invention relates to a video encoding device for encoding a video signal. Background technique [0002] In recent years, digital video cameras have been widely used to capture moving pictures (video), encode the pictures to generate a compressed stream, and then record the digital signal of the stream to a recording medium. As far as encoding is concerned, standards such as DVC, MPEG-2 (ISO / IEC 13818-2), and MPEG-4 (ISO / IEC 14496-2) have been widely used. [0003] Furthermore, a standard called H.264 (ITU-T Rec. H.264), whose original purpose is aimed at video coding for teleconferencing, has recently been standardized. Although the H.264 standard requires more encoding and decoding processing than the MPEG-2 standard and the MPEG-4 standard, it can achieve higher encoding efficiency. [0004] One of methods for achieving high coding efficiency by utilizing entropy coding of the H.264 standard is a coding method called content-based adapt...
