What is your failure in this job? 

 

Answer 4

 

查了一下你发来的CPK档， 该测试项会自动检测设备的输入信号源及频率值，请确定测试时有正确的信号源。

 

以下是相关的logo requirement:

 

STREAM-0016	TV tuner detects signals from all input sources
TV tuners mustbeable to detect signals from all implemented input sources (such asRF, composite, and S-Video). Sharing connections internally between S-Video and composite auxiliary inputs makes discrete signal detection between these two inputs impossible. For this reason Microsoft strongly discourages sharing connections internally between independent auxiliary connectors. The driver must correctly expose the proper mediums and media types related to information off the crossbar pins to determine which S-Video or composite jack matches to which S-Video jack. OpenCable Unidirectional Receivers (which can tune to both terrestrial and cable, analog and digital content) must be able to scan and detect signals on the various modulation types (such asNTSC, 8VSB, QAM64, and QAM256). OpenCable Unidirectional Receivers (OCUR) must also comply with requirements outlined in DTOS for CableLabs certification of OCUR devices.
Design And Implementation Notes :
Microsoft recommends that analog tuners meet video quality and RF certification requirements for TV tuners as specified by ISF Research Labs.

Answer 6

从错误信息来看，确实是你的信号可能有问题。

你能在GraphEdit或者MCE或者第三方播放工具中收到信号吗？

 

另外，你也可以手工试一下这个命令，看是否可以通过。

tvwlptest <test case ID> “<Device ID of device you want to test>”

Answer 7

 

问题已得到解决,是没有对上相应的频率值.
