Method and device for receiving processing data and video server

Abstract

The invention provides a method and a device for receiving processing data and a video server. The method comprises the following steps of: predefining a memory file model, wherein a read pointer, a read query method, a write pointer, a write query method and a memory file length are encapsulated in the memory file model; creating a memory file for each on-demand dialogue on a memory space; invoking the write query method to obtain the current writable data length of the memory file; if the writable data length is greater than zero, transmitting data request to a content delivery network according to the on-demand request, wherein the length of the requested transmitted data is not greater than that of the writable data; receiving and analyzing the data returned from the content delivery network; writing the analyzed data into the memory file, and updating the position pointed by the write pointer. The method using the self-defining memory file provided by the invention can read and write on a single memory, the utilization ratio of the memory is improved and the read-write speed is balanced, and thus the data processing is stable to smooth the push flow.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a method, device and video server for receiving and processing data. Background technique [0002] Digital TV is an end-to-end system that digitally processes signals from program acquisition, program production, program transmission to the user end. Broadcast and interactive digital TV based on DVB (Digital Video Broadcasting, Digital Video Broadcasting) technical standards. The use of advanced user management technology can perfect the quality and quantity of program content and bring users more program choices and better program quality effects. Compared with analog TV, digital TV has high image quality, large program capacity and Good sound effects. [0003] Due to the large capacity of the program, media files are rarely stored on the VS (Video Server, video server), but are generally stored in each node of the CDN (Content Distribute Network, content distribution network...

AI Technical Summary

Problems solved by technology

[0007] The memory utilization rate of the above method is only about 50%, and it is easy to cause delays in the processing of chunked data, because only when one of the memory is full or all data is received and parsed, the other memory can be read out for processing (such as streaming). VS may be in a waiting state

In addition, receiving and parsing chunked data is currently unlimited

Obtain chunked data from the CDN, analyze it while receiving it, and read it out after the analysis is completed. To a certain extent, the rate at which VS processes chunked data depends on the rate at which data is transmitted by the CDN. When the network is unstable, VS pushes The stream will be very unstable and affect the user experience
