Embodiment Construction

[0036] The detailed technical features of the present invention will be further described below in conjunction with the accompanying drawings, so as to understand the present invention more clearly.

[0037] The video distributed buffer transfer system of the present invention is provided with a video buffer at the sending end of the video signal, and when the video buffer sends the video signal to each data channel, the processing unit detects and corrects the video signal.

[0038] see figure 1As shown, it is a functional block diagram of the video distributed buffer transfer system of the present invention. In the present invention, the system includes a video signal sending end 1, a video data buffer unit 2, a signal detection unit 3, and a signal correction unit 4 , a processing unit 5, at least one data channel and a data receiving end corresponding to each data channel.

[0039] In the present invention, the video signal sending end 1 sends frame video signals, and eac...

Abstract

The invention relates to a video distributed cache transfer system which comprises a signal emitting end, a video data cache unit, a signal detecting unit, a signal correcting unit, a processing unit and at least one data channel. The signal emitting end transmits video data to the video data cache unit and the processing unit. The video detecting unit is placed behind the video data cache unit, and comprises a first comparing module, a first storing module and a first delaying module inside. The signal correcting unit comprises a second processing module, a second delaying module, a second comparing module and a correction circuit. Since multiple video data detecting modules and signal correcting modules are arranged in the video distributed cache transfer system, that signals have relatively high accuracy and relatively low distortion factor during cache transfer is guaranteed, so that relatively clear video images can be obtained on the reception by a remote device.

Description

technical field [0001] The invention relates to a video distributed cache system, in particular to a video distributed cache transfer system with detection and repair functions. [0002] Background technique [0003] When the video buffer transfer system in the prior art transmits the monitoring signal to the remote end, the video signal is directly transmitted to the remote signal receiving end through the data channel. During the signal buffering process, only the synchronous or blanking signal is isolated. [0004] For example, the Chinese patent "Distributed Cache System, Data Cache Method, and Cache Data Query Method", patent publication number CN102006330, discloses a distributed cache system, including: at least two cache server groups; each cache server The group has at least one cache server node; wherein one cache server group in the at least two cache server groups and one cache server node in the one cache server group serve as the main cache server group and th...
