Exemplary embodiments are directed to methods and systems for annotating generating training data for video quality impairment detection. A video stream recorder extracts one or more image frames from a reference video stream as it is played. A video image labeler embeds a unique label into each of the one or more extracted image frames. The video stream recorder records the one or more labeled image frames as a labeled video stream. The video stream player then plays the labeled video stream through an impaired communication channel to generate a degraded video stream. A video image comparator compares one or more corresponding frames of the labeled video stream and the degraded video stream to generate one or more difference frames. An impaired image recorder annotates at least one of the one or more difference frames according to a corrupted region of the at least one difference frame.

Automatic annotation of video quality impairment training data for generating machine learning models of video quality prediction

A method is presented for detecting visual artifacts such as macroblocking artifacts appearing in a rendering of a video stream. A decoded video stream that includes a plurality of frames is received. Edges appearing in the plurality of frames are detected and data characterizing the edges is directed to a neural network. The neural network determines a likelihood that a macroblocking artifact occurs in the video stream using the neural network. The neural network is trained using training data that includes (i) one or more video sequences having known macroblocking artifacts whose size and duration are known and (ii) user ratings indicating a likelihood that users visually perceived macroblocking in each of the one or more video sequences when each of the one or more video sequences are rendered.

Advanced recording options are provided on a personal versatile recorder (PVR) or similar recording device. Television signals and associated electronic programming guide (EPG) data are received at a receiver (). Recorded program material is stored in a storage device (). A processor () provides for automatic suspending of recording, based on predetermined criteria, for at least a portion of time during which the one or more television programs would otherwise be recorded. Recording may be suspended when non-programming specific content (e.g., a commercial or emergency broadcast) is received at the PVR (). Non-program specific content can be identified through the use of EPG data or Advanced Television Enhancement Forum (ATVEF) triggers. End of program notifiers may be provided which enable the PVR () to record the entire program, regardless of whether the program runs beyond its scheduled time. Recording may be optionally suspended where the program is a rerun.
