Problems solved by technology

But if the frequency of sending the detection signal is set too high, it will reduce the effective bandwidth that affects the transmission of the network 20; 12 has stopped transmission and when the packet of the buffer 16 has been played, the player 14 still continues to repeat the last output data packet of the buffer 16

Embodiment Construction

[0022] see figure 2 , figure 2 It is a functional block diagram of the media player system 30 of the present invention. The media playback system 30 includes a data terminal 32 and a playback terminal 34 , and the data terminal 32 and the playback terminal 34 are connected to each other through a network 20 . The data end 32 includes an encoder (encoder) 42, which is used to encode the media data packet to be transmitted to the playback end 34, and the playback end 34 includes a buffer (buffer) 36 and a decoder (decoder) 38, the buffer The area 36 is used to store the input media data packets, and the decoder 38 is used to decode the media data packets. Before the playback terminal 34 plays the media data of the data terminal 32, the playback terminal 34 will pre-download a section of media data and store it in the buffer 36, and the playback terminal 34 will use the media data packets in the buffer 36 for playback .

Abstract

The system consists of a data terminal and a displaying terminal. The displaying terminal is connected with the data terminal through a network. The data terminal includes an encoder used in encoding media data. The displaying terminal includes a buffer used in storing package of media data. The method compares the package numbers of media data stored in the buffer with an upper limit value and a lower limit value. If the package numbers is more than the upper limit value the encoding speed for the media data will be reduced. If the package numbers is less than the lower limit value the encoding speed for the media will be increased.

Description

technical field [0001] The invention relates to a media playing system, in particular to a method for controlling the operation of the media playing system by using flow control and dynamically adjusting the critical value of the size of the media data packet stored in the buffer. Background technique [0002] The way of human information dissemination has evolved from static media (text, graphics) to dynamic media (music, video), and with the rapid development of network transmission technology, in just a few decades, online music and Online videos have gradually become an indispensable source of information and entertainment for human beings every day. [0003] However, the playback of online music and online videos will be limited by network bandwidth and transmission quality. Since the Internet (Internet) has the characteristics of interconnection but no mutual management, the bandwidth actually available to users can never be fixed, that is to say, the bandwidth provid...
