Device, system and method for providing order program contents

Abstract

The embodiment of the invention discloses a method, a system and an apparatus for providing ordered contents, wherein the method for providing ordered contents comprises: calculating the heat of ordered contents and saving the request contents into a flash disk according to the calculated heat, so when a media server receives the ordering request, priority will be given to the ordered content saved in the flash disk. Through saving the hot movies into the flash disk inside the stream media server, the execution example of the invention can increase I / O read / write speed, and therefore improve the performance of unit stream media servers. Moreover, the flash disk is characterized in that no data are lost in power-off status; therefore, it is not necessary to read data of hot movies from hard drives into the flash disk even in a restart process, so as to improve the start-up speed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method, system and device for providing on-demand content. Background technique [0002] With the development of multimedia technology, communication technology, and hardware storage technology, in order to meet the needs of users at different levels, VOD (Video On Demand, video on demand) services have emerged as the times require. The operator prepares a large number of movies in advance and stores them in the video-on-demand system, and the user can send a request to the video-on-demand system to control the playback of the program at will. The server cost and network bandwidth cost occupied by video-on-demand are very high. After learning from each other's strengths and weaknesses, some new services are integrated, such as: nPVR (network Personal Video Recording, network personal video recording), TSTV (TimeShift Television, time-shifte...

AI Technical Summary

Problems solved by technology

However, at present, some streaming media application systems still use 32 bits, so that the maximum available memory of such streaming media application systems is only 4GB. , so only 4 movies can be cached at most

The new hardware system and operating system have begun to support 64-bit. The 32-bit streaming media application system can be upgraded to support 64-bit by modifying the code. Theoretically, it can support 17179869184GB of memory, but it is limited to the number of memory slots on the motherboard and a single memory In general, a server can be configured with a maximum of more than ten GB of memory, and can only cache more than a dozen movie programs at most, so there is a problem that the number of movies stored in the memory is small

Moreover, the cost of memory is relatively high. At present, a 1GB memory stick in the market costs several hundred yuan or more, which increases the investment burden to some extent.

Using the method of putting the hot chip into the memory, it is necessary to read the data of the hot chip from the hardware into the buffer every time it is started, which may greatly affect the startup speed and reduce the operating speed

[0006] In the process of realizing the present invention, the inventor has found that the prior art has at least the following problems: in the existing method of using the thermal film stored in the internal memory to alleviate the slow disk read and write speed, the number of films that can be stored in the internal memory is small, and the cost Higher, lower overall startup rate
