Abstract
The invention discloses a real-time video recording caching technology based on a memory. The technology is characterized in that streaming video data can be saved on a computer; a data buffer file system of the memory can be established; the data buffer file system comprises a recording progress and a delete control progress; in the recording progress, the streaming media video data can be sliced and separated at intervals of 1 second; the sliced streaming media video data is used as a video file to store in the memory according to the time sequence; the total time length of the single video file produced in the recording progress is 15 minutes; and in the delete control progress, the post video file is deleted based on given time intervals, so that the memory is guaranteed not being overflowed. According to the technology provided by the invention, the writing and reading of the video data are in the memory, high speed writing and reading data can be realized through utilizing the high bandwidth of the memory, thus, the cost is low, the reliability is strong, and long time and continuous working can be realized.
Description
Technical field
The present invention relates to the computer internet technical field, especially relate to a kind of real-time video based on internal memory and record caching technology.
Background technology
along with film, TV, the development of Internet video, numerous films and television programs and programs that splendid contents is arranged have been produced, many loyal spectators that like these works and program have also appearred, there are a lot of spectators can be because of various reasons, can not in time watch and oneself want the programme televised live seen, such as just on the road or the spectators that hurrying on a journey, for convenience of this class spectators, occurred to watch with oneself at any time the portable handheld terminal of program, as mobile TV etc., intuitive with TV media, the portability of broadcast medium, the anelasticity of Newspaper Media and the characteristics such as interactivity of the network media, be subject to welcoming widely, but present mobile TV or a kind of technology that has just grown up, therefore there are a lot of jejune places, its general using stream media technology is come the transmission of video program by the mobile network, resource consumption is large, network easily stops up, the mobile TV picture postpones, the memory device that satisfies the lower normal operation of the long-time preservation of program and high speed writing speed (needs can reach hundreds of million/seconds) is of a high price, and under frequent read-write state, the reliability of general non-volatile memory device can reduce greatly, be difficult to satisfy long-time continual work requirements.
Summary of the invention
The present invention records in order to solve existing real-time video memory device or the high utilization and extention that is difficult to of price that caching technology adopts, or functional reliability is hanged down problems such as can not satisfying long-time non-stop run demand, a kind of memory device of using price high of need not is provided, and functional reliability is strong, and the real-time video based on internal memory of non-stop run is for a long time recorded caching technology.
to achieve these goals, the present invention is by the following technical solutions: the real-time video based on internal memory is recorded caching technology, can preserve on computers streaming media video data, set up the data buffering file system of an internal memory, described data buffering file system comprises that is recorded a process, a deletion control process, the described process of recording is cut into slices to streaming media video data and is cut apart, streaming media video data after section is kept in internal memory as video file in chronological order, described deletion control process is carried out deletion action to the video file before given interval and is guaranteed that internal memory can not overflow.This programme directly uses internal memory to cushion as video data, and writing and reading of data is all in internal memory, utilizes the high bandwidth advantage of internal memory, can obtain reading and writing data speed at a high speed, and cost is very low; The read-write reliability of internal memory also is better than other high speed nonvolatile storage mediums greatly, can satisfy the requirement of long-time uninterrupted read-write; Internal memory cushions as video data, be used for to preserve the current time with the video data in for the previous period, and the video data the limiting time scope before can abandon (deletion) can not overflow the memory buffer memory block with the assurance video data.
As preferably, described recording in process carries out cutting apart for the section at interval in 1 second to streaming media video data.The mode of streaming media video data being cut into slices take second as unit is simplified the implementation complexity that conventional video cushions greatly, can improve Systems balanth.
As preferably, described to record the single video file T.T. length that produces in process be 15 minutes.When program recording, program source can have a plurality of, if each program was preserved than the long program time, can cause intensified pressure to the capacity of internal memory, therefore, the file size that each program of moderate control is preserved in the memory buffer memory block can more reasonably be made good use of the memory buffer memory block.
Therefore, the present invention has following beneficial effect: 1) video data to write and read be all in internal memory, utilize the high bandwidth of internal memory to reach the high-speed read-write data, and cost is very low; 2) write in internal memory with the reliability of reading out data strong, non-stop run for a long time.
Embodiment
Below the present invention will be further described.
real-time video based on internal memory is recorded caching technology, can preserve on computers streaming media video data, set up the data buffering file system of an internal memory, the data buffering file system comprises that is recorded a process, a deletion control process, record in process streaming media video data is carried out cutting apart for the section at interval in 1 second, streaming media video data after section is kept in internal memory as video file in chronological order, recording the single video file T.T. length that produces in process is 15 minutes, deletion control process is carried out deletion action to the video file before given interval and is guaranteed that internal memory can not overflow.
Claims (3)
1. the real-time video based on internal memory is recorded caching technology, can preserve on computers streaming media video data, it is characterized in that, set up the data buffering file system of an internal memory, described data buffering file system comprises that is recorded a process, a deletion control process, the described process of recording is cut into slices to streaming media video data and is cut apart, streaming media video data after section is kept in internal memory as video file in chronological order, described deletion control process is carried out deletion action to the video file before given interval and is guaranteed that internal memory can not overflow.
