A system for monitoring the quality of DRM-protected multimedia data streams, the system comprising at least one computer having a network connection to receive at least one said DRM-protected multimedia data stream, program memory, working memory, and a processor coupled to said program memory, working memory, and wherein said program memory stores processor control code for a media player for said multimedia data stream and code to control said processor to: play said DRM-protected multimedia data stream to provide at least a decrypted video data output stream for display on a monitor; capture still image data from a succession of still images from said video data output stream; process said still image data to detect greater than a threshold difference between at least two of said still images; and output fault data identifying a potential video quality fault responsive to absence of detection of said greater than a threshold difference.
A system for monitoring the quality of DRM-protected multimedia data streams, the system comprising at least one computer having a network connection to receive at least one said DRM-protected multimedia data stream, program memory, working memory, and a processor coupled to said program memory, working memory, wherein said program memory stores processor control code for a media player for said multimedia data stream and code to control said processor to:
A system for monitoring the quality of DRM-protected multimedia data streams, the system comprising at least one computer having a network connection to receive at least one said DRM-protected multimedia data stream program memory, working memory, and a processor coupled to said program memory and working memory, and wherein said program memory stores processor control code for a media player for said multimedia data stream and code to control said processor to:
A method of monitoring the quality of a multimedia data stream provided over the internet, the method comprising:
A physical data carrier carrying processor control code to implement a method of monitoring the quality of a multimedia data stream provided over the internet, said code comprising code to:
