AI Technical Summary

Benefits of technology

Non-limiting embodiment solves problems of supporting interlaced video format in HEVC encoding and decoding. The invention separates out unnecessary information and only sends necessary data to the decoding and display levels, improving independence and reducing processing requirements. This improves the efficiency of video decoding devices, facilitating their development for different display devices.

Problems solved by technology

However, as described above, the HEVC which is currently in the standardization process defines an encoding method only for the progressive format and does not enable encoding of interlace contents.

first embodiment

Encoding Process

[0063]The first embodiment will be described with reference to the drawings.

1. Configuration of a Video Encoding Device

[0064]FIG. 1 is a block diagram of a video encoding device according to the embodiment.

[0065]The video encoding device 100 includes a picture setter 101, a video format specifying unit 102, a display control information generator 103, a second code string generator 104, and a picture data encoder 110. The picture data encoder 110 includes a picture memory 111, a prediction residual encoder 112, a prediction residual decoder 113, a local buffer 114, a prediction encoder 115, a quantization value determiner 116, and a first code string generator 117.

[0066]The picture setter 101 sorts input video signals 151 which are input in a display order in units of pictures in an encoding order according to video format signals 152 input from the video format specifying unit 102, and outputs the sorted input video signals 151 to the picture data encoder 110. At th...

second embodiment

Decoding Process

[0136]The second embodiment will be described with reference to the drawings.

1. Configuration of a Video Decoding Device

[0137]FIG. 9 is a block diagram of a video decoding device according to the embodiment.

[0138]The video decoding device 200 includes a second code string analyzer 201, a display control information analyzer 202, a picture data decoder 210, and an output picture setter 203. The picture data decoder 210 includes a first code string analyzer 211, a prediction residual decoder 212, a picture memory 213, a prediction decoder 214, and a quantization value determiner 215.

[0139]The second code string analyzer 201 extracts display control information and information about decoding control in units of sequences and decoding control in units of pictures from a code string of header information included in input code string signals 251. Then, the second code string analyzer 201 outputs the extracted information to the display control information analyzer 202 as ...

third embodiment

Another Example of Encoding Process

[0191]The third embodiment will be described with reference to the drawings.

1. Configuration of a Video Encoding Device

[0192]FIG. 14 is a block diagram of a video encoding device according to the embodiment.

[0193]The video encoding device 100-1 includes a picture data encoder 110-1 and a second code string generator 104-1 in place of the picture data encoder 110 and the second code string generator 104 of the video encoding device 100 of the first embodiment. The picture data encoder 110-1 includes a first code string generator 117-1 in place of the first code string generator 117.

[0194]For convenience of the description, a detailed description of the same configuration as that of the first embodiment will be omitted below. Further, in FIG. 14, blocks which have the same functions as those of the blocks in FIG. 1 are denoted by the same numbers as the blocks in FIG. 1.

[0195]The picture data encoder 110-1 divides each picture input from the picture ...

Abstract

A video decoding device, in the case where a video of the progressive format is inputted, processes a frame as a picture, in the case where a video of the interlace format is inputted, processes a field as a picture. A video decoding device performs display control corresponding to a format of the both video by analyzing display control information in display control information analyzer. The display control information includes sequence unit display control information which is commonly used in a display process of all pictures that belong to a sequence to be decoded and picture unit display control information which is individually used in a display process of a picture to be decoded. A second code string analyzer acquires each of the sequence unit display control information and the picture unit display control information from an extended information area in units of pictures.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation application of International Application No. PCT / JP2012 / 003910, with an international filing date of Jun. 14, 2012, which claims priorities of Japanese Patent Application No.: 2011-134891 filed on Jun. 17, 2011, and Japanese Patent Application No.: 2011-175815 filed on Aug. 11, 2011, the contents of which are incorporated herein by references.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates to a video decoding device and a video decoding method for receiving input encoded progressive video signals and encoded interlace received video signals and decoding the video signals.[0004]2. Related Art[0005]In recent years, as multimedia application programs have been developed, integrated use of information from various media including video, audio, and text has prevailed. However, a digitized video contains a large amount of data. Then, video compression technologies are essential to store and transmit...
