摘要： There is disclosed a packet transmission apparatus for transmitting in a packet form a transmission unit including a data string arranged so as to divide predetermined data into a plurality of blocks, each block having a fixed length, block information for specifying the block type being added to each block. A DIF data processing circuit generates a transmission header having a new identifier by deleting predetermined redundancy information from the block information belonging to the plurality of blocks based on inputted data string, and then, generates a transmission unit having the generated transmission header. Next, a transmission terminal unit transmits the generated transmission unit by way of a transmission line. In this case, the DIF data processing circuit generates a new identifier by making the information of one block represent the information of the plurality of blocks to generate a transmission header having the generated identifier, or making the information of one block represent the information of an identical block or deleting the redundancy information including at least one of reserved data and invalid data.

With this, encoding quantity control according to the characteristics of the input video signal can be performed between layers. Also, with selection of encode modes and sharing of a motion vector, the encoded data of a bidirectionally predicted frame can be reduced and the encoding efficiency of a high resolution signal can be increased.

摘要： A method of coding image data with coefficients between fields by increasing the coefficients prior to coding comprising the steps of: (1) detecting a motion vector in a reference field to a sample field to check whether the reference field is zoomed in or out relative to the sample field, data of the reference field being coded based on the sample field; (2) zooming out the reference field when the reference field is zoomed in relative to the sample field, and zooming in the reference field when the reference field is zoomed out relative to the sample field according to the motion vector; and (3) coding the reference field after the reference field has been zoomed according to the motion vector in the second step. In the second step, the reference field may be zoomed out by eliminating pixels that are not adjacent in one of a vertical direction and a horizontal direction.

摘要： A digital video signal reproducing apparatus is arranged such that when a low frequency component of a reproduced signal is extracted, the reproduced signal forms a reproduced image plane. When a low frequency component of a reproduced signal is extracted but a high frequency component thereof is not extracted, the low frequency component thus extracted is compared with a low frequency component of a previously or subsequently reproduced signal. If the two low frequency components are substantially equal to each other, the reproduced signal is concealed to form a reproduced image plane, and if not substantially equal to each other, the reproduced signal forms a reproduced image plane without being concealed.

摘要： A non-linear signal processing apparatus used in a video tape recorder or a video disk player is disclosed. The time variation of an input signal or a processed version thereof is non-linearly processed by a differential circuit and a closed loop including a non-linear circuit. The non-linearly processed time variation of the signal or a processed version thereof is arithmetically combined with the input signal. Thus, the same non-linear characteristic as that obtained by the prior art analog signal technique is attained by the digital signal processing technique, which is superior in integrity and stability. By appropriately selecting the characteristic of the non-linear circuit, better results than those obtainable by the analog signal processing technique are achieved.
