Problems solved by technology

However, because the quality of service (Quality of Service, QoS) of the network cannot be guaranteed sometimes, it will cause bandwidth variation (Bandwidth Variation), which will cause temporary interruption of broadcasting, and static pictures or Vibrating, unclear images, or even no content, create a bad impression on users
[0005] In addition, in the existing terrestrial digital program broadcasting process, the quality of the broadcast signal will fluctuate in a certain area for a period of time, especially for users who are moving, due to the influence of moving speed or the occlusion of buildings, the signal quality will be affected. Jitter (Signal Quality Variation) is particularly obvious, which will also cause temporary interruption of broadcasting, and user interfaces such as TV screens will appear static or jittery images, or even have no content, giving users a bad impression

Embodiment Construction

[0021] figure 1 It is a schematic diagram of a system for inserting pre-arranged programs during network digital broadcasting according to an embodiment of the present invention. The digital program broadcasting system includes a program broadcasting device the same as the existing broadcasting system, and also includes a detection device for detecting the broadcast quality of the normal program being played, and a switching device for when the detected broadcast When the quality is lower than a predetermined value, pre-arranged programs, that is, other programs are inserted, and the playback quality of the other programs is greater than the user's acceptable level, that is, reaches a predetermined standard. The program playback device generally further includes a network interface 112 , a protocol decomplexer 114 , a network buffer 116 , a PID filter 121 , a normal program buffer 123 , a demultiplexer 127 and a decoder 129 .

Abstract

The present invention provides one method of digital program broadcasting method. During broadcasting, when bandwidth jitter or signal quality jitter happens to make the program quality lower than some set value, some pre-arranged programs with specific broadcasting quality, such as ads, may be inserted. The pre-arranged programs may has some correlation to the program in broadcasting. The present invention makes it possible for the viewer to view some program without need of tolerating jittered picture and just waiting. The present invention also provides the method of counting the inserted program for charging.

Description

technical background [0001] The present invention relates to a digital program broadcasting method and system, in particular to an IP Broadcasting method / system and a Terrestrial Digital Video Broadcasting (DVB-T, Terrestrial Digital Video Broadcasting) method / system. [0002] The MPEG (Motion Picture Experts Group) 2 standard (ISO / IEC 13818-1) is a relatively popular standard for digital TV broadcasting. This standard is a standard used to provide digital data streams for digital devices such as set-top boxes (STB), digital television (DTV), interactive digital television (iDTV), personal computers, handheld devices and other interactive devices. [0003] MPEG 2 over IP is a method of packaging data streams conforming to the MPEG 2 standard, such as TCP / IP (Transmission Control Protocol / Internet Protocol) packets or UDP (User Datagram Protocol) / IP packets, for transmission on the Internet. The method is a better method for broadcasting network digital programs. [0004] In ...
