Encoding for super resolution playback

A method of producing video data of a particular resolution, comprising:

• generating estimated high resolution video data from low resolution video data received at a display device, wherein the low resolution is lower than the high resolution, the low resolution video data comprising interlaced fields of video data;
• producing estimated low resolution video data from the estimated high resolution video data by applying filters to the estimated high resolution video data, the filters using a different set of filter coefficients for each of the different fields in a frame in the estimated low resolution video data, wherein the set of filter coefficients applied depends upon a field number received at the filter;
• differencing the estimated low resolution video data and the received low resolution video data to generate difference data;
• and
• using the difference data to generate new estimated high resolution video data.

A video display device, comprising:

• a port configured to receive low resolution video data from a video transmission device;
• a processor to:
• generate estimated high resolution video data from low resolution video data received at a display device, wherein the low resolution is lower than the high resolution;
• produce estimated low resolution fields of video data from the estimated high resolution video data by applying a filter having different coefficients for at least one field of the estimated low resolution video data than used to produce other fields in the estimated low resolution video data, wherein the different coefficients selected depends upon a field number for a field received at the filter;
• difference the estimated low resolution video data and the received low resolution video data to generate difference data;
• and
• use the difference data to generate new estimated high resolution video data.

A video system, comprising:

• a video transmission device, comprising:
• a port configured to receive high resolution video data from an image capture device;
• a processor to apply a filter to the video data to produce fields of interlaced low resolution video data of a lower resolution than the video data received from the image capture device, such that at least one field results from a different set of coefficients than a set of coefficients applied to at least one other field such that a resulting image appears to be a progressive picture having the same content as the fields of interlaced low resolution video data, wherein the set of coefficients selected depends upon a field number of the field received at the filter;
• a port to transmit the interlaced low resolution video data;
• and
• a video display device, comprising:
• a port configured to receive the interlaced low resolution video data;
• a processor to reconstruct the high resolution video data from the interlaced fields of low resolution video data by using a low pass filter from the video transmission device having different a different set of filter coefficients applied to at least one field than a set of filter coefficients applied to other fields.
