Patent ID: 7961780

Claim:
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.
