Abstract
A system and method for monitoring a sequence of video packets for quantifying video quality includes a video picture monitor that accesses data in a header of a video packet included in the sequence of video packets. The header is separate from video content stored in the video packet. The video picture monitor also determines from the accessed data, a relationship between a portion of a picture included in the video packet and at least a portion of a picture included in another video packet. Both video packets are included in the sequence of video packets. This relationship indicates whether to use the video content stored in the first video packet to quantify video quality.
Claims20
A method of monitoring video packets for quantifying video quality, comprising:
- accessing data in a portion of a header of a first video packet included in a sequence of video packets, wherein the header is separate from video content stored in the first video packet;
- and
- determining from the accessed data, an inter-packet relationship between a portion of a picture included in the first video packet and at least a portion of a picture included in a second video packet that is included in the sequence of video packets based on picture types of a compression technique associated with the sequence of video packets, wherein the inter-packet relationship indicates whether to use a portion of the video content stored in the first video packet.
A system for monitoring a sequence of video packets for quantifying video quality, comprising:
- a video picture monitor configured to access data in a portion of a header of a first video packet included in the sequence of video packets, wherein the header is separate from video content stored in the first video packet, the video picture monitor is also configured to determine from the accessed data, an inter-packet relationship between a portion of a picture included in the first video packet and at least a portion of a picture included in a second video packet that is included in the sequence of video packets based on picture types of a compression technique associated with the sequence of video packets, wherein the inter-packet relationship indicates whether to use a portion of the video content stored in the first video packet.
A non-transitory computer readable medium encoded with a computer program product having a plurality of instructions, when executed by a processor, cause that processor to:
- access data in a portion of a header of a first video packet included in a sequence of video packets, wherein the header is separate from video content stored in the first video packet;
- and
- determine from the accessed data, an inter-packet relationship between a portion of a picture included in the first video packet and at least a portion of a picture included in a second video packet that is included in the sequence of video packets based on picture types of a compression technique associated with the sequence of video packets, wherein the relationship indicates whether to use a portion of the video content stored in the first video packet to quantify video quality.
