Problems solved by technology

For example, the quality of live audio and video broadcasting of TV broadcasting is very good, and the user experience is high, but the multimedia services based on the Internet are limited by the bandwidth factor, which makes the transmission of audio and video streams not smooth enough, resulting in poor video signal quality, discontinuous pictures, and delays. Major and other issues
[0006] In addition, it is impossible for any kind of network to completely achieve seamless coverage. In some areas, the mobile phone signal may be good, while in other areas the signal is not good. In an area with poor signal, assuming that the user is watching the live video on the mobile phone, the live signal may be poor, affecting the user to watch

Embodiment 1

[0085] Embodiment 1: The receiving terminal switches from the Internet receiving mode to the mobile multimedia broadcasting network receiving mode.

[0086] The user logs in to the live video program of a website on the Internet through the terminal, the receiving terminal receives the multimedia service data of the website through the Internet access module, and plays the multimedia service for the user through the webpage embedded player or a separate media player.

[0087] When the receiving terminal starts to play the multimedia service, it starts the service monitoring module to detect the receiving quality of the multimedia service currently being played, such as bit error rate (BER), frame error rate (FER) and so on. If the quality of the program is found to be poor (for example, the bit error rate or frame error rate is lower than the set threshold), which affects the user experience, it will automatically detect whether the mobile multimedia broadcast receiving module ...

Embodiment 2

[0091] Embodiment 2: The receiving terminal is switched from the mobile multimedia network receiving mode to the Internet receiving mode.

[0092] After the user selects to receive a certain live video program through the user interface of the mobile multimedia broadcasting network on the receiving terminal, the multimedia broadcasting service data is received through the corresponding physical channel according to the physical channel configuration information corresponding to the multimedia service and the service number, and is sent by the mobile multimedia service. The player supported by the broadcast receiving module presents the multimedia service playback to the user.

[0093] When the receiving terminal starts to play the multimedia service, it starts the service monitoring module to detect the performance parameters of the currently playing multimedia service, such as bit error rate (BER), frame error rate (FER) and so on. If it is detected that the performance param...

Embodiment 3

[0097] The receiving terminal can further provide the user with a unified multimedia service user interface. When the user needs to select a multimedia service, after entering the user interface and selecting a multimedia service, the receiving terminal calls the service monitoring module, and monitors the bandwidth, mobile The multimedia broadcast service receiving module monitors the broadcast channel to obtain broadcast channel quality parameters, compares the quality in the two modes, and prompts the user to select a receiving mode with better channel quality, and after the user selects the mode to watch and play the multimedia service; or Alternatively, after the user selects a certain multimedia service, it is possible to determine which mode has better channel quality when receiving the service, without prompting the user to select, and automatically start the mode to watch and play the multimedia service.

[0098] After selecting the Internet access mode or the mobile m...

Abstract

The invention discloses a multimedia transmission system, a receiving terminal and the receiving method. The receiving terminal can receive multimedia service from a mobile multimedia broadcasting service server through a mobile multimedia broadcasting network, also can receive the identical multimedia service from a website server through the internet, monitors the quality of the multimedia service received in two receiving methods during the initial receiving process and the multimedia service playing process of the receiving terminal, and selects a receiving method with the service quality meeting the playing requirements according to the receiving quality to receive the multimedia service. Through the application of the invention, switching between two network transmission methods can be performed, the purpose of network coverage and complement is achieved, the disadvantage that a single network can not be seamlessly covered is overcome, and thus the users can be provided with the multimedia service better.

Description

technical field [0001] The present invention relates to the technical field of multimedia communication, in particular to a multimedia network transmission system, a receiving terminal and a multimedia transmission method. Background technique [0002] At present, wireless or cable radio and television services have covered many parts of the earth. People can receive various real-time TV programs or radio programs through TV sets or radios, and keep abreast of the latest news, local customs, and enjoy film and television around the world.
