Embodiment Construction

[0007] On the basis of the digital signal receiving module, digital signal conversion module, digital signal decoding module, control module, digital signal transmission module and digital signal playing module in the existing mobile TV broadcasting system, a digital signal storage buffer module is added. The digital signal storage and buffering module stores video information with a length of 2s for buffering and playing. The digital signal buffering time to achieve the best playback effect is 2s, that is, the digital signal playback time is 2s slower than the digital signal receiving time.

[0008] The received signal passes through the conversion module and the decoding module to obtain the transmission code stream, and then the control module calls the transmission code stream decoding module to process and store it in the buffer processing module, and the buffer processing module inputs the digital TV signal 2s before to the digital signal playback module; It also include...

Abstract

The invention relates to a method for broadcasting mobile TV programs smoothly. The prior system for broadcasting mobile TV programs is additionally provided with a digital storing and buffering module in addition to a digital signal receiving module, a digital signal converting module, a digital signal decoding module, a controlling module, a digital signal transmitting module and a digital signal broadcasting module, thus mobile TV program broadcasting speed is slower than the signal receiving speed, the received instant signals are stored by the digital storing and buffering module, and the mobile TV programs can be broadcasted consecutively and smoothly under the condition that the wireless signals are interrupted suddenly. The invention has reasonable design and low cost, is convenient to use, is safe, reliable and environmental friendly and can be popularized and applied to various buses or large-size passenger cars.

Description

Technical field: [0001] The invention relates to a mobile TV playing method, in particular to a mobile TV smooth playing method. Background technique: [0002] At present, on-board mobile TVs are generally installed on buses and coaches. However, due to the instability of wireless signals, the TV screen and sound often appear intermittently and intermittently. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the intermittent and unstable situation of the vehicle-mounted mobile TV signal, and provide a mobile TV smooth playing method with reasonable design, simple structure, convenient use, safety, reliability, energy saving and environmental protection. [0004] The technical solution adopted to solve the above problems is: [0005] The mobile TV smooth playing method is characterized in that: on the basis of a digital signal receiving module, a digital signal conversion module, a digital signal decoding module, a cont...
