Abstract
The present invention discloses a digital video compression device and method, and belongs to the technical field of computers. The device comprises an all-in-one machine, a processor and a digital interface which is configured on the all-in-one machine and used for receiving digital videos, and the digital videos are output from the digital interface after being compressed by the all-in-one machine.
Description
Technical field
The present invention relates to a kind of apparatus and method of compression of digital video, belong to field of computer technology.
Background technology
A series of static image is caught, is recorded, is processed, stored and is transmitted in the mode of the signal of telecommunication and the various technology of reappearing by video general reference.Continuous print image change more than more than 24 frame pictures time, human eye cannot distinguish the tableaux of single width; Look it is level and smooth continuous print visual effect, such continuous print picture is called video.
The prosperity of network technology impels video to exist with the form of streaming media, is called as video traffic, is called multimedia communication, streaming media communication etc. in computer realm at field of telecommunications.Be widely used in the directions such as program request, live, the network teleconference, remote teaching, IPTV, mobile video.
Video data transmission occupied bandwidth is very high, and memory space takies greatly, and efficient compress technique can reduce offered load, and reduces storage system space hold.
Summary of the invention
The invention provides a kind of device of compression of digital video, second-compressed can be carried out to encoded vision signal, effectively reduce video bandwidth and take and memory space.
The device that the present invention proposes, comprising: all-in-one; Processor; And digital interface, be configured on this main frame, in order to receive digital video, after all-in-one compression process, and from then on digital interface exports.

Embodiment
Hereafter for introducing the preferred embodiments of the present invention.Each embodiment in order to principle of the present invention to be described, but is not used to limit the present invention.Scope of the present invention is when being as the criterion with appending claims.
Fig. 1 is that the digital video compressor proposed according to the present invention uses schematic diagram, and all-in-one 100 at least comprises a digital interface 110, or comprises multiple digital interface 110 and 120.
According to the present invention, digital interface 110,120 is configured on video-unit 100, by digital interface and other equipment connections, and incoming video signal.For example, digital interface can be network interface, also can be PCIE interface.In more detail, network interface can be connected with other video equipments by Internet protocol, incoming video signal; Also can be connected by PCIE bus, incoming video signal.Compression processing unit carries out compression process to incoming video signal, exports from any digital interface.Be familiar with this skill personage and can recognize that the present invention need not as limit.
Fig. 2 is structured flowchart of the present invention.Input interface, output interface are digital interface in the present invention, are all connected with Video compression unit.
Digital interface 110, for receiving digital video signal, exports to Video compression unit by digital video signal.
Digital interface 120, for sending the digital video signal after compression.
Fig. 3 is the structured flowchart of compression processing unit 130 of the present invention, and it also comprises demultiplexing unit 210, video flowing temporary storage location 220, audio frequency temporary storage location 230, frame analytic unit 240, frame compression unit 250, compressed feedback unit 260, and Multiplexing Unit 270.
The video flowing that demultiplexing unit 210 sends in order to receive digital interface 110, separating video, audio frequency export video temporary storage location 220 respectively to, and audio frequency temporary storage location 230.Frame analytic unit 240 is in order to receiver, video stream temporary storage location 220 data, and analyze video requency frame data, bivalve value scene switching judging, extracts multiple key value.The key value that frame compression unit 250 pairs of frame analytic units 240 export is as input, second-compressed is carried out to frame of video selectivity, compression rear video frame exports feedback unit 260 to, feedback unit 260 Output rusults and source frame of video are carried out computing by frame analytic unit 240, draw compression assessed value Δ Z, compare with preset value T, as Δ Z < T, frame compression unit 250 exports result to Multiplexing Unit 270, as Δ Z > T, frame compression unit 250 adjusts compression parameters, result is exported to Multiplexing Unit 270.Audio stream temporary storage location 230 exports to Multiplexing Unit 270 by straight-through for voice data, and the multiplexing packing of video flowing after straight-through audio stream and compression exports by multiplexer 270.
In digital video compressor of the present invention, processor, for controlling and perform the command operating of compression algorithm, mainly completes and obtains instruction, performs instruction, and with the operation such as internal storage and logical block exchange message.
Claims (5)
1. realize a device for compression of digital video, comprising: all-in-one; Processor; And digital interface, be configured on this main frame, in order to receive digital video, after all-in-one compression process, and from then on digital interface exports.
