Embodiment Construction

[0044] The present invention will be further described in detail in conjunction with the following specific embodiments and accompanying drawings. The process, conditions, experimental methods, etc. for implementing the present invention, except for the content specifically mentioned below, are common knowledge and common knowledge in this field, and the present invention has no special limitation content.

[0045] Such as figure 1 The device for decoding enhanced mobile carrier image smoothness of the present invention mainly includes a video decoding unit and its control unit. The video decoding unit is used for receiving video signals and decoding the video signals, so as to generate video image data for display. The video image data is output to the display device as a video picture. When the video signal received by the video decoding unit is missing or interrupted, the video screen on the display device will appear mosaic and short-term black screen. The control unit ...

Abstract

The invention discloses an image decoding apparatus for enhancing maneuvering carrier video smoothness. The image decoding apparatus includes a video decoding unit and a control unit. The video decoding unit receives a video signal and decodes the video signal, and generates and outputs video image data for displaying. The control unit connected with the video decoding unit is used for controlling the video decoding unit to carry out smoothing processing on the displayed image when interrupting or losing of the video signal received by the video decoding unit occurs. According to the invention, smoothness of the satellite video; and the occurrence probability of the mosaic jamming and black screen can be reduced. In addition, the invention also discloses a decoding method of the image decoding apparatus for enhancing maneuvering carrier video smoothness, and an image decoding system for enhancing maneuvering carrier video smoothness and a decoding method thereof.

Description

technical field [0001] The present invention relates to an image decoding method, in particular to an image decoding device and system and a decoding method for enhancing the smoothness of mobile carrier video. Background technique [0002] In domestic and foreign vehicle / shipborne satellite TV receiving equipment specifications and product standards, the RMS (root mean square value) statistical method is used for the annotation of antenna tracking accuracy. For automatic tracking satellite antenna products, this means that short When the star is lost, but the probability of star loss is required to be lower than a certain index value. At present, in the satellite communication applications of mobile carriers such as ships or vehicles, there is a certain probability that the receiving system loses satellites for a short time. [0003] For satellite data communications, data interruption caused by star loss can be retransmitted to ensure complete reception. However, in broa...
