Abstract
A method of concealing a packet loss during video decoding is provided. An input stream having a plurality of network abstraction layer units NAL is received. A loss of a network abstraction layer unit in a group of pictures in the input stream is detected. A valid network abstraction layer unit order from the available network abstraction layer units is outputted. The network abstraction layer unit order is received by a video coding layer (VCL) and data is outputted.
Claims8
Method of concealing a packet loss during video decoding, comprising the steps of:
- receiving an input stream having a plurality of network abstraction layer units (NAL),
- detecting a loss of a network abstraction layer unit in a group of pictures in the input stream,
- outputting a valid network abstraction layer unit order from the available network abstraction layer units,
- receiving the network abstraction layer unit order by a video coding layer (VCL) and outputting data.
Video coder unit, comprising
- a network abstraction layer means (NAL) for receiving an input stream having a plurality of network abstraction layer units for detecting a loss of a network abstraction layer unit in a group of pictures and for outputting a valid network abstraction layer unit order based on the available network abstraction layer units;
- and
- a video coding layer means (VCL) for receiving the network abstraction layer unit order and for outputting data based on the network abstraction layer unit order.
