Embodiment Construction

[0052] In a one-way broadcast network such as mobile multimedia broadcasting, it includes a system end and a file download terminal. The system end continuously sends a file within a specific period of time (that is, within the file life cycle), and the terminal can choose to download the file according to the demand. The terminal download The download status information of the file is recorded at the same time. When the download is interrupted and resumed again, the terminal continues to download from the interrupted download point according to the recorded download status information, so as to realize the resuming of the broken point.

[0053] The process of sending files from the system end (ie, the file sending end) includes the following steps:

[0054] Step 1. The file sending end divides the file into several file pieces of equal length, and forms the file blocks by multiple file pieces, and records the block information at the same time;

[0055] The file sending end d...

Abstract

The invention provides a method for downloading a document, realizing transmission resuming at break-points. The method can be applied to a unilateral broadcasting network which comprises a document transmitting terminal and a document receiving terminal, wherein, the document transmitting terminal sends down a document; the document receiving terminal records download state information of the document while downloading the document; when the download is interrupted and recovered once more, the document receiving terminal continues downloading from the download break-point according to the recorded download state information, thereby realizing the transmission resuming at break-points. The invention also provides a method, a system and a terminal for downloading the document capable of realizing the transmission resuming at break-points, thereby realizing the transmission resuming at break-points for document downloading after interruption during downloading the document in the unilateral broadcasting network.

Description

technical field [0001] The invention relates to a one-way broadcasting system, in particular to a file downloading method, system and terminal capable of realizing resuming transmission from breakpoints. Background technique [0002] One-way broadcasting system, such as mobile multimedia broadcasting, is a broadcasting multimedia playback technology that has emerged in recent years. Through the hand-held terminal, in the case of high-speed movement, you can watch multimedia services such as TV. The terminal receives the multimedia service program list through the wireless broadcast channel, and can select the channel it has the right to watch, so that it can receive and select the multimedia data of the channel, and realize watching TV on the mobile terminal. [0003] File download is an important function of mobile multimedia broadcasting. The standard GY / T 220.5-2008 "Mobile Multimedia Broadcasting Part 5: Data Broadcasting" defines the transmission mode and business mode...
