Abstract

In a method for transmitting video for a display panel between a transmitter in electronic communication with a receiver over a wireless communication channel, the method includes: receiving, by a transmitter, a frame of video data from a data source; reorganizing, by the transmitter, the frame of video data into a plurality of packets according to levels of importance of bits of the frame of video data; generating, by the transmitter, a tag for each of the packets, the tags corresponding to different relatively levels of importance of the packets; performing, by the transmitter, different protection techniques for each of the packets based on the tag corresponding to each of the packets; and transmitting, by the transmitter, the packets and the tags to the receiver for display on the display panel such that each packet is transmitted according to the different protection techniques based on their corresponding tagging.

Claims (55)

1. A method for transmitting video for a display panel, the method comprising:

receiving, by a transmitter, a frame of video data from a data source, wherein the frame of video data comprises a plurality of pixel data;

reorganizing, by the transmitter, the frame of video data into a plurality of packets according to levels of importance of bits of the frame of video data, wherein the levels of importance of bits comprise:

a first level of importance for a most significant bits of each pixel data; and

a second level of importance for a least significant bits of each pixel data, wherein the first level of importance is greater than the second level of importance;

receiving, by the transmitter, a return signal from a receiver operating on the display panel, wherein the transmitter is in electronic communication with the receiver over a wireless channel;

generating, by the transmitter, a tag for each of the packets, the tags corresponding to different relatively levels of importance of the packets, wherein the tag of each packet corresponds to a modulation and coding scheme (MCS) value based on their corresponding level of importance and the return signal;

performing, by the transmitter, different protection techniques for each of the packets based on the tag corresponding to each of the packets; and

transmitting, by the transmitter, the packets and the tags to the receiver for display on the display panel such that each packet is transmitted according to the different protection techniques based on their corresponding tagging.

2. The method of claim 1 , wherein the tag of each of the packets comprises adding a bit pattern indicating a relative importance level of a packet to a header of the packet.

3. The method of claim 1 , wherein more important packets have a lower MCS value than less important packets.

4. The method of claim 1 , wherein the tag of each packet further corresponds to a forward error correction coding rate based on their corresponding level of importance.

5. The method of claim 1 , further comprising:

packing, by the transmitter, the packets into a plurality of Aggregated MAC Protocol Data Unit (A-MPDU) subframes; and

transmitting, by the transmitter, the A-MPDU subframes to the receiver.

6. The method of claim 5 , further comprising:

tagging, by the transmitter, a plurality of Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU) frames with a same tag;

packing, by the transmitter, the A-MPDU subframes having a same importance level into the PPDU frames; and

transmitting, by the transmitter, the PPDU frames to the receiver.

7. The method of claim 1 , further comprising selecting, by the transmitter, the different protection techniques for different regions of an image of the frame of video data according to a type of display device corresponding to the receiver.

8. A transmitter for transmitting data for a display panel, the transmitter being configured to:

receive a frame of video data from a data source;

reorganize the frame of video data into a plurality of packets according to levels of importance of bits of the frame of video data, wherein the levels of importance of bits of the frame of video data comprise:

a first level of importance for a most significant bits of each pixel data; and

a second level of importance for a least significant bits of each pixel data, wherein the first level of importance is greater than the second level of importance;

receiving, by the transmitter, a return signal from a receiver operating on the display panel, wherein the transmitter is in electronic communication with the receiver over a wireless channel;

generate a tag for each of the packets, the tags corresponding to different relatively levels of importance of the packets, wherein the tagging of each packet corresponds to a modulation and coding scheme (MCS) value based on their corresponding level of importance and the return signal;

perform different protection techniques for each of the packets based on the tag corresponding to each of the packets; and

transmit the packets and the tags to the receiver for display on the display panel such that each packet is transmitted according to the different protection techniques based on their corresponding tagging.

9. The transmitter of claim 8 , wherein the tagging of each of the packets comprises adding a bit pattern indicating a relative importance level of a packet to a header of the packet.

10. The transmitter of claim 8 , wherein the tagging of each packet corresponds to a forward error correction coding rate based on their corresponding level of importance.

11. The transmitter of claim 8 , wherein the transmitter is further configured to:

pack the packets into a plurality of Aggregated MAC Protocol Data Unit (A-MPDU) subframes; and

transmit the A-MPDU subframes to the receiver.

12. The transmitter of claim 11 , wherein the transmitter is further configured to:

tag a plurality of Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU) frames;

pack the A-MPDU subframes having a same importance level into the PPDU frames; and

transmit the PPDU frames to the receiver.

13. A method for transmitting video for a display panel between a transmitter in electronic communication with a receiver over a wireless communication channel, the method comprising:

receiving, by a transmitter, a frame of video data from a data source, wherein the frame of video data comprises a plurality of pixel data;

reorganizing, by the transmitter, the frame of video data into a plurality of packets according to levels of importance of bits of the frame of video data, wherein the levels of importance of bits of the frame of video data comprise:

a first level of importance for a most significant bits of each pixel data; and

a second level of importance for a least significant bits of each pixel data, wherein the first level of importance is greater than the second level of importance;

generating, by the transmitter, a tag for each of the packets, the tags corresponding to different relatively levels of importance of the packets, wherein the tagging of each packet corresponds to a modulation and coding scheme (MCS) value based on their corresponding level of importance and a return signal from the receiver;

monitoring, by the transmitter, for the return signal from the receiver;

adjusting, by the transmitter, a protection technique based on a change in at least one of channel quality or video quality; and

transmitting, by the transmitter, the packets and the tags to the receiver for display on the display panel such that each packet is transmitted according to the protection technique based on their corresponding tagging.

14. The method of claim 13 , wherein the tag of each of the packets comprises adding a bit pattern indicating a relative importance level of a packet to a header of the packet.

15. The method of claim 13 , further comprising:

packing, by the transmitter, the packets into a plurality of Aggregated MAC Protocol Data Unit (A-MPDU) subframes; and

transmitting, by the transmitter, the A-MPDU subframes to the receiver.

16. The method of claim 15 , further comprising:

tagging, by the transmitter, a plurality of Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU) frames with a same tag;

packing, by the transmitter, the A-MPDU subframes having a same importance level into the PPDU frames; and

transmitting, by the transmitter, the PPDU frames to the receiver.
