Problems solved by technology

Since the recorded transport stream usually includes the information of multiple programs, the amount of data is very large, so using the above method will consume a large amount of bandwidth, resulting in a great waste of resources

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] The system framework adopted by the transport stream sharing method disclosed in the present invention includes a server end and a client end, and the server end and the client end transmit data to each other through a network. There are pre-recorded transport streams and index files stored on the server side. Wherein, the server end may be a set-top box, etc., and the client end may be a personal computer, mobile phone, TV or tablet computer, etc.

[0021] As known to those skilled in the art, a transport stream contains multiple pieces of program information and is composed of multiple transport stream data packets. Each transport stream packet is 188 bytes. The structure of the transport stream is as follows:

[0022]

[0023] A transport stream packet consists of a header and a payload. Among them, the header is 32-bit data, includin...

Abstract

Disclosed is a method for sharing a transport stream. The method comprises: receiving a sharing request, the sharing request comprising a packet identifier; and sending a transport stream data packet in the transport stream and corresponding to the packet identifier. In the present invention, by means of the foregoing manner, merely a transport stream data packet corresponding to a packet identifier of a sharing request in a transport stream is sent according to the demand of a user, and transmission of another unnecessary transport stream data packet is avoided, thereby saving network bandwidth and effectively sharing the transport stream.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for sharing transmission streams. Background technique [0002] As the functions of the set-top box become more and more abundant, people can obtain many other functions besides watching digital TV programs with the set-top box, and the recording function is one of them. When using the recording function, the recorded program will automatically generate a transport stream (TS) and store it. Users can call the recorded transmission stream through the set-top box to watch at any time. If the recorded transport stream needs to be watched on other devices, such as personal computers, mobile phones, etc., the transport stream can be directly shared through the network and downloaded and accessed by other devices. Since the recorded transport stream usually includes information of multiple programs, and its data volume is very large, using the above method will consum...
