Problems solved by technology

[0008] For the radio and television industry with a huge video network, the demand for video DBS is very large. In the existing technology, three modes are generally used for VOD backup under failure, among which the active / standby mode and dual activation mode are one-to-one backup modes. Therefore, the system cost is increased; in addition, the cluster mode of proxy supervision technology is adopted, and a proxy server is configured one-to-one for each DBS, and the proxy server communicates with the supervision center. If the DBS operating system or communication network fails, the proxy server and The monitoring center cannot communicate, which may cause network confusion, so that the faulty DBS cannot be accurately monitored, resulting in the monitoring center being unable to determine whether the DBS has stopped broadcasting, and the simultaneous broadcasting of the main and backup DBSs in the network will affect the normal viewing of users

Embodiment 1

[0044] A central storage system of cable television VOD includes several DBSs, a backup DBS, monitoring server, broadcast management server and switch equipment. If any DBS fails, the system will shift the business to the standby DBS to take over the work of the failed DBS, which will be described in detail with a specific embodiment below.

[0045] In the embodiment of the present invention, it is assumed that a central storage system of cable TV VOD includes four DBSs, a backup DBS, a monitoring server, a broadcast management server and two gigabit network switches, wherein the monitoring server and the broadcast management server are in In the same area, the specific interface and connection method are as follows figure 2 shown.

[0046] see image 3 , the embodiment of the present invention provides a kind of method for cable television VOD backup, specifically comprises:

[0047] 301: The user sends a video-on-demand request on the client;

[0048] The client may be a ...

Embodiment 2

[0097] see Figure 4 , the embodiment of the present invention provides a system for cable TV VOD backup, specifically comprising:

[0098]The broadcast management server 401 is used to receive the video-on-demand request of the user and specify the target MAC address; receive the system state information and user state information of the DBS, back up the user state information locally, and package the system state information into a test package; receive the monitoring server The switching command sent is to execute the translation of the active and standby DBS broadcasting services through the VBS, and at the same time send the completion command;

[0099] The first switch 402 is used to receive the user's VOD request, and switch to the corresponding DBS port according to the target MAC address specified by the broadcast management server 401; receive the system status information and user status information reported by the DBS, and switch to the playback manager 401 Corres...

Embodiment 3

[0126] see Figure 5 , the embodiment of the present invention also provides a broadcast management server, specifically including:

[0127] The receiving unit 501 is configured to receive the user's initial video-on-demand request, system status information and user status information, and a switching instruction sent by the monitoring server;

[0128] The backup unit 502 is configured to locally back up the user state information received by the receiving unit 501;

[0129] Packing unit 503, the user packs the system status information received by the receiving unit 501 into a test package;

[0130] The test packet is a network data packet in Ethernet frame format;

[0131] The switching unit 504 is used for forwarding the user state information backed up by the backup unit 502 to the backup DBS according to the switching instruction received by the receiving unit 501, and shifting the broadcast service of the faulty DBS to the backup DBS;

[0132] Specifically, the switc...

Abstract

The invention discloses a backup method, system and device of a CATV VOD which belongs to the CATV technical field. The method includes steps as follows: a broadcast management server obtains system state information and user state information of the broadcast server, transmits the system state information and backups the user state information; a monitor server receives and analysis the system state information, and judges the broadcast server whether having fault according with the system state information; if fault exist, the monitor server transmits a switch indication to the broadcast management server; the broadcast management server receives the switch indication, executes broadcast operation translation of the main-backup broadcast server according with the user state information; the monitor server receives a finish indication, closes the server broadcast terminal, and opens the broadcast server terminal. The system comprises: the broadcast server, the broadcast management server and the monitor server. The invention can detect system fault in all directions, finish the broadcast operation backup, and reduce the system cost.

Description

technical field [0001] The invention relates to the technical field of cable TV, in particular to a method, system and equipment for cable TV VOD backup. Background technique [0002] With the commercialization of cable television VOD (Video On Demand, video on demand), system stability becomes a key issue of VOD. However, no matter how stable the system is, failure events cannot be avoided, such as operating system failure, network failure, and broadcast system failure. In a very small range, it has become a problem that all cable TV VODs must face. [0003] Currently, VOD backup modes include active / standby mode, dual active mode, and cluster mode. [0004] Active / standby mode, that is, one DBS (Digital Video Broadcastingt Server, broadcast server) is in the working state, and one DBS is in the standby state. When the working DBS fails, the standby DBS starts to enter the working state to take over the work of the DBS. [0005] Dual activation mode, that is, one-to-one ...
