Retry disparity for control channel of a multimedia communication link
View Patent ↗A multimedia system for data communications. A source device communicates data over a full duplex control channel of a multimedia communication link. The source device has a first link layer that retries unsuccessful data communications over the full duplex control channel until a first maximum retry limit of the first link layer is reached. A sink device communicates data over the full duplex control channel of the multimedia communication link. The sink device has a second link layer that retries unsuccessful data communications over the full duplex control channel until a second maximum retry limit of the second link layer is reached, where the second maximum retry limit is different than the first maximum retry limit.
1. A system for data communications, the system comprising:
a multimedia communication link having a full duplex control channel;
a source device to communicate data over the full duplex control channel of the multimedia communication link, the source device having a first link layer that retries unsuccessful data communications over the full duplex control channel until a first maximum retry limit of the first link layer is reached; and
a sink device to communicate data over the full duplex control channel of the multimedia communication link, the sink device having a second link layer that retries unsuccessful data communications over the full duplex control channel until a second maximum retry limit of the second link layer is reached, the second maximum retry limit being different than the first maximum retry limit.
2. The system of claim 1 , wherein the first maximum retry limit is higher than the second maximum retry limit.
3. The system of claim 1 , wherein the first maximum retry limit is lower than the second maximum retry limit.
4. The system of claim 1 , wherein the first maximum retry limit is equal to 4X+3, wherein X is an integer.
5. The system of claim 4 , wherein the second maximum retry limit is equal to 4Y+1, wherein Y is an integer.
6. The system of claim 1 , wherein an unsuccessful data communication is indicated by a receipt of a negative acknowledgement via the full duplex control channel.
7. The system of claim 1 , wherein the data communicated by the source device corresponds to data from a half-duplex translation layer protocol.
8. A first device for data communications with a second device via a multimedia communication link, the first device comprising:
an interface to a full duplex control channel of the multimedia communication link; and
a link layer to communicate data with the second device over the full duplex control channel, the link layer to retry unsuccessful data communications over the full duplex control channel until a first maximum retry limit is reached, the first maximum retry limit being different than a second maximum retry limit of a link layer of the second device.
9. The first device of claim 8 , wherein the first maximum retry limit is higher than the second maximum retry limit.
10. The first device of claim 8 , wherein the first maximum retry limit is lower than the second maximum retry limit.
11. The first device of claim 8 , wherein the first maximum retry limit is equal to 4X+3, wherein X is an integer.
12. The first device of claim 11 , wherein the second maximum retry limit is equal to 4Y+1, wherein Y is an integer.
13. The first device of claim 8 , wherein an unsuccessful communication is indicated by a receipt of a negative acknowledgement via the full duplex control channel.
14. The first device of claim 8 , wherein the data communicated by the first device corresponds to data from a half-duplex translation layer protocol.
15. A non-transitory computer readable medium storing a representation of a first device for data communications with a second device via a multimedia communication link, the first device comprising:
an interface to a full duplex control channel of the multimedia communication link; and
a link layer to communicate data with the second device over the full duplex control channel, the link layer to retry unsuccessful data communications over the full duplex control channel until a first maximum retry limit is reached, the first maximum retry limit being different than a second maximum retry limit of a link layer of the second device.
16. The non-transitory computer readable medium of claim 15 , wherein the first maximum retry limit is higher than the second maximum retry limit.
17. The non-transitory computer readable medium of claim 15 , wherein the first maximum retry limit is lower than the second maximum retry limit.
18. The non-transitory computer readable medium of claim 15 , wherein the first maximum retry limit is equal to 4X+3, wherein X is an integer.
19. The non-transitory computer readable medium of claim 18 , wherein the second maximum retry limit is equal to 4Y+1, wherein Y is an integer.
20. The non-transitory computer readable medium of claim 15 , wherein an unsuccessful communication is indicated by a receipt of a negative acknowledgement via the full duplex control channel.
