A method to reconstruct the received video sequence seen at the receiver using transmission error information to monitor the perceptual video quality at the receiver in digital cable television and video telephony
This Recommendation specifies a method for a transmitting side to reconstruct the received video sequence in order to monitor video quality at the receiver using transmission error information for packetized video transmission. This Recommendation applies to video services where two-way digital communications are available. The method in this Recommendation requires that each packet can be traced and identified. Some packet transport protocols such as RTP(Real-time Transport Protocol) and ATM(Asynchronous Transfer Mode)/AAL(ATM Adaptation Layer) have this feature. In order to evaluate video quality at the receiver, the method needs to be used with an objective model for video quality measurement such as J.144. It is suggested that a standardized method should be used.
