Abstract

A data stream format for transmission of data frames between a computer and a video client via an interface, the data stream being a plurality of data frames transmitted sequentially, each data frame comprising: a frame header; video data, the video data following the frame header; and audio data, the audio data following the video data.

Claims (52)

1 . A method of processing data frames, comprising:

receiving input data from a client device at a device interface;

converting, using the device interface, at least a portion of the input data into a data frame, wherein the data frame comprises video data and audio data;

dividing, using the device interface, the data frame into a first portion and a second portion;

constructing, using the device interface, a first partial frame that includes a first header and the first portion;

constructing, using the device interface, a second partial frame that includes a second header and the second portion;

transmitting, using the device interface, the first partial frame over a first channel to a computing device; and

transmitting, using the device interface, the second partial frame over a second channel to the computing device, wherein the first channel and the second channel are different.

2 . The method of claim 1 , wherein converting, using the device interface comprises:

creating, using the device interface, scanned lines based on the input data;

performing, using the device interface, deinterlacing and packetizing of the scanned lines; and

generating, using the device interface, the data frame based upon the deinterlacing and packetizing of the scanned lines.

3 . The method of claim 1 , wherein transmitting the first partial frame over the first channel comprises synchronizing the transmission of the first partial frame with a vertical blanking interval defined between the device interface and the computing device.

4 . The method of claim 3 , wherein the first header comprises a synchronization bit that is synchronized with the vertical blanking interval.

5 . The method of claim 3 , wherein the vertical blanking interval corresponds to a frequency of a plurality of other data frames transmitted to the computing device.

6 . The method of claim 1 , wherein the data frame further comprises an audio header, and wherein the audio header is located between the video data and the audio data.

7 . The method of claim 6 , wherein the audio header includes an audio sample count that is indicative of a number of audio samples in accordance with a cadence.

8 . The method of claim 7 , wherein the audio header includes an audio cycle count that is indicative of a location within the cadence.

9 . The method of claim 1 , wherein the first header comprises format flags that are indicative of the number of bits per sample of video data.

10 . A non-transitory machine readable medium that comprises instructions that when executed by at least one processor causes a device interface of a programmable device to:

receive input data from the programmable device;

convert at least a portion of the input data into a data frame, wherein the data frame comprises video data and audio data;

divide the data frame into a first portion and a second portion;

construct a first partial frame that includes a first header and the first portion;

construct a second partial frame that includes a second header and the second portion;

transmit the first partial frame over a first channel to a computing device; and

transmit the second partial frame over a second channel to the computing device, wherein the first channel and the second channel are different.

11 . The non-transitory machine readable medium of claim 10 , wherein the instructions to convert comprises instructions that cause the device interface to:

create scanned lines based on the input data;

perform deinterlacing and packetizing of the scanned lines; and

generate the data frame based upon the deinterlacing and packetizing of the scanned lines.

12 . The non-transitory machine readable medium of claim 10 , wherein the instructions to transmit the first partial frame over the first channel comprises instructions that cause the device interface to synchronize the transmission of the first partial frame with a vertical blanking interval defined between the device interface and the computing device.

13 . The non-transitory machine readable medium of claim 12 , wherein the first header comprises a synchronization bit that is synchronized with the vertical blanking interval.

14 . The non-transitory machine readable medium of claim 12 , wherein the vertical blanking interval corresponds to a frequency of a plurality of other data frames transmitted to the computing device.

15 . The non-transitory machine readable medium of claim 10 , wherein the data frame further comprises an audio header, and wherein the audio header is located between the video data and the audio data.

16 . A system, comprising:

a-processor; and

a memory coupled to the processor, wherein instructions are stored in the memory, the instructions comprising instructions that when executed cause a device interface of a client device to:

receive input data from the programmable device;

convert at least a portion of the input data into a data frame, wherein the data frame comprises video data and audio data;

divide the data frame into a first portion and a second portion;

construct a first partial frame that includes a first header and the first portion;

construct a second partial frame that includes a second header and the second portion;

transmit the first partial frame over a first channel to a computing device; and

transmit the second partial frame over a second channel to the computing device, wherein the first channel and the second channel are different.

17 . The system of claim 16 , wherein the instructions to convert comprises instructions that cause the device interface to:

create scanned lines based on the input data;

perform deinterlacing and packetizing of the scanned lines; and

generate the data frame based upon the deinterlacing and packetizing of the scanned lines.

18 . The system of claim 16 , wherein the instructions to transmit the first partial frame over the first channel comprises instructions that cause the device interface to synchronize the transmission of the first partial frame with a vertical blanking interval defined between the device interface and the computing device.

19 . The system of claim 18 , wherein the first header comprises a synchronization bit that is synchronized with the vertical blanking interval.

20 . The system of claim 18 , wherein the vertical blanking interval corresponds to a frequency of a plurality of other data frames transmitted to the computing device.
