Embodiment Construction

[0036] like figure 1 As shown, the steps of the method for data push provided by the present invention in combination with the radio and television cable network and the Internet are as follows:

[0037] S10. The file segmentation module in the front-end server divides the data files to be transmitted according to the predetermined capacity and packs them into multiple data packets, and the digital TV playback card in the front-end server broadcasts them sequentially to multiple set terminal receivers via the wired network Data packet, S20, the terminal control playback module in the terminal receiver receives the data packet in sequence, and the data information in the data packet is saved to the corresponding mobile hard disk by the data push storage module, S30, the terminal receiver receives the data packet The integrity of the data packet is judged, S40, when the data packet is complete, directly stop the loop broadcast; The Internet supplements the terminal receivers un...

Abstract

The invention discloses a data push method by a broadcast and TV wired network with the Internet. A file segmentation module in a front-end server segments a data file to be transferred into multiple data packets, and a digital TV play card in the front-end server broadcasts the data packets to multiple set terminal receivers cyclically sequentially via the wired network; terminal control play modules in the terminal receivers receive the data packets sequentially, and store data information in the data packets in corresponding mobile hard disks; the terminal receivers determines the completeness of the received data packets; and when certain data packet is incomplete, a big data sending module in the corresponding terminal receiver sends a packet reissue request to the front-end server via the Internet, the front-end server reissues packets to the terminal receivers via the Internet till the front-end server receives data packet completeness signals from all the terminal receivers, and cyclic broadcast is stopped. The method is rapid and economical in data transmission, and is more flexible in regional delivery.

Description

technical field [0001] The invention relates to the field of electronic communication transmission, in particular to a method for data push by combining a radio and television cable network and the Internet. Background technique [0002] During the use of the radio and television cable network, large-capacity data files such as movies and digital books are mainly transmitted through the network. Taking movies as an example, the existing ways of transmitting movies mainly include the following methods: [0003] 1) Transmission via express hard disk [0004] The method is to first copy the movie to the hard disk, and then transmit the hard disk to each theater by express. The main disadvantage is that it takes a long time to copy the movie to the hard disk, the cost of equipment is high, and the time for each theater to get the movie is inconsistent. For theaters in some remote areas of Inner Mongolia and Xinjiang, due to inconvenient transportation and harsh environment, mo...
