Generated set top calibration patterns in manufacturing
View Patent ↗Included are systems and methods for performing an internal operations test to a set top terminal (STT). At least one embodiment of a method includes creating a test pattern for testing video functionality of the STT, sending the created test pattern to a digital encoder, and converting the test pattern to an analog signal.
1. A system operative to perform an internal operations test, the system comprising:
a memory storage having stored thereon a test pattern, the memory storage being operative to send the test pattern to at least one component of the system;
a decoder configured to receive the test pattern, convert the test pattern into a transport stream, and send the converted test pattern to the at least one component of the system;
a frame buffer configured to receive the converted test pattern, hold the converted test pattern, and send the test pattern to the at least one component of the system;
an encoder configured to receive the converted test pattern, convert the converted test pattern to an analog signal, and send the analog signal to the at least one component of the system;
an analog output configured to receive the analog signal and output the analog signal to at least one of the following: the at least one component of the system and a Video Measurement System (VMS) coupled to the analog output;
the VMS being configured to receive the analog signal, determine a deviation from the stored test pattern and the analog signal, and send data associated with the determination to a storage device; and
a radio frequency (RF) modulator configured to modulate the analog signal and output the modulated analog signal to the at least one component of the system.
2. The system of claim 1 , further comprising a graphics engine operative to generate the test pattern.
3. The system of claim 1 , further comprising an attenuator configured to receive the modulated analog signal, attenuate the modulated analog signal, and send the attenuated analog signal to the at least one component of the system.
4. The system of claim 3 , further comprising an RF input configured to receive the analog signal and provide the analog signal to a tuner.
5. The system of claim 4 , wherein the tuner is operative to tune the STT to a channel represented by the analog signal.
6. The system of claim 1 , further comprising a computing device coupled to the VMS, the computing device being configured to send commands to operate the VMS.
7. A method operative to perform an internal operations test, the method comprising:
sending, from a memory storage having stored thereon a test pattern, the test pattern to at least one component of a system;
receiving, by a decoder, the test pattern;
converting, by the decoder, the test pattern into a transport stream;
sending, by the decoder, the converted test pattern to the at least one component of the system;
receiving, by a frame buffer, the converted test pattern;
holding, by the frame buffer, the converted test pattern;
sending, by the frame buffer, the test pattern to the at least one component of the system;
receiving, by an encoder, the converted test pattern;
converting, by the encoder, the converted test pattern to an analog signal;
sending, by the encoder, the analog signal to the at least one component of the system;
receiving, by an analog output, the analog signal;
outputting, by the analog output, the analog signal to at least one of the following: the at least one component of the system and a Video Measurement System (VMS) coupled to the analog output;
receiving, by the VMS, the analog signal;
determining, by the VMS, a deviation from the stored test pattern and the analog signal;
sending, by the VMS, data associated with the determination to a storage device;
modulating, by a radio frequency (RF) modulator, the analog signal; and
outputting, by the RF modulator, the modulated analog signal to the at least one component of the system.
8. The method of claim 7 , further comprising generating the test pattern by a graphics engine.
9. The method of claim 7 , further comprising:
receiving, by an attenuator, the modulated analog signal;
attenuating, by the attenuator, the modulated analog signal; and
sending, by the attenuator, the attenuated analog signal to the at least one component of the system.
10. The method of claim 9 , further comprising:
receiving, by an RF input, the analog signal; and
providing, by the RF input, the analog signal to a tuner.
11. The method of claim 10 , further comprising tuning, by the tuner, the STT to a channel represented by the analog signal.
12. The method of claim 7 , further comprising sending, by a computing device coupled to the VMS, commands to operate the VMS.
