Embodiment

[0022] In the method for automatically tuning the performance of the set-top box tuner in the embodiment of the present invention, it is necessary to set the controller to be connected to the signal generator and the set-top box respectively, and the signal generator is connected to the set-top box. Here, the controller and the signal generator can be connected by a network cable. The controller and the set-top box can be connected through the serial port.

[0023] The method specifically includes the following steps:

[0024] Step 1. The controller loads the digital TV code stream, analyzes and stores the TS packet information in it, and the TS packet information includes at least the number of TS packets, and sends the digital TV code stream to the signal generator.

[0025] Step 2. The controller selects an indicator to be tested as the current debugging indicator.

[0026] Step 3. The controller reads the digital TV signal corresponding to the initial signal parameter of ...

Abstract

The invention relates to the technology of a set top box, aims at solving the problem that an existing set top box low noise block performance index needs to be adjusted artificially and provides a set top box low noise block performance automatic adjustment and optimization method. The technical scheme may be summarized as the fact that a controller is connected with a signal generator and the set top box; the signal generator is connected with the set top box; the low noise block performance is automatically judged through utilization of the number of TS packets of code streams and the number of the TS packets received by the set top box; and the low noise block performance is adjusted and optimized according to an algorithm. The method has the beneficial effects that the adjustment efficiency is improved, the artificial participation is reduced, and the method is applicable to the adjustment of the set top box low noise block performance index.

Description

technical field [0001] The invention relates to the technology of the set-top box, in particular to the technology of the tuner of the set-top box. Background technique [0002] The performance index of the tuner is the most important indicator of the hardware performance of the radio set-top box. When the performance of the tuner is not good, the packet loss rate is high under the corresponding signal conditions, which directly leads to mosaics and popping sounds in the video played by the set-top box, affecting Users watch it, but since the performance index of the tuner is related to the hardware layout and peripheral circuit parameters, each set-top box needs to be adjusted and optimized. [0003] At present, the industry generally adopts manual adjustment of signal parameters, and then observes whether there is any abnormality such as mosaic in the playback of the set-top box, and then rewrites the chip register to adjust. However, since there are more than 20 performa...
