Each device is configured to execute a web browser application. One of the devices is referred to as a streamer device, and the other a receiver device. The receiver device includes a camera for receiving images displayed by the streamer device. A user of the streamer device can orient the display of the streamer towards the camera of the receiver device. The receiver device uses the camera to observe images displayed by any streamer devices that are present within the field of view of the camera. The receiver device, via the camera, analyzes each video frame displayed by the streamer device for a pattern. If the pattern is detected and matches a predefined pattern, the receiver device can retrieve information associated with the pattern, and display that information in the web browser. ## Claims ### Claim 1 A computer-implemented method comprising: receiving, from a camera of a first device, a series of image frames generated and displayed by a web browser of a second device, the series of image frames having an image pattern steganographically hidden therein; and causing the first device to display, via a video display of the first device, information associated with the image pattern generated and displayed by the web browser of the second device, wherein the image pattern matches a predefined image pattern associated with a user of the second device. ### Claim 2 (depends on 1) The method of claim 1, wherein the image pattern is visually imperceptible by a human when the image frames are rendered sequentially. ### Claim 3 (depends on 1) The method of claim 1, further comprising: analyzing, by a processor, the image frames to locate the image pattern; and matching, by the processor, the image pattern with a predefined image pattern; wherein the information is further associated with the predefined image pattern. ### Claim 4 (depends on 3) The method of claim 3, further comprising associating the predefined image pattern with a user account, wherein the information is customized based on the user account. ### Claim 5 (depends on 1) The method of claim 1, wherein the image pattern includes at least one of a barcode and a color pattern. ### Claim 6 (depends on 1) The method of claim 1, wherein the image pattern appears for approximately 1/60th of a second. ### Claim 7 (depends on 1) The method of claim 1, wherein the image pattern appears in a single frame of the series of image frames. ### Claim 8 A computer-implemented method comprising: receiving digital content from a server, the digital content including a series of image frames received from a camera of a first device, the series of image frames being generated and displayed by a web browser of a second device, the series of image frames having an image pattern steganographically hidden therein; and rendering, via a video display of the first device, the series of image frames generated and displayed by the web browser of the second device, wherein the image pattern matches a predefined image pattern associated with a user of the second device. ### Claim 9 (depends on 8) The method of claim 8, wherein the content is visually perceptible by a human and the image pattern is visually imperceptible by a human when the image frames are rendered sequentially. ### Claim 10 (depends on 8) The method of claim 8, wherein the image pattern appears for approximately 1/60th of a second. ### Claim 11 (depends on 8) The method of claim 8, wherein the image pattern appears in a single one of the series of image frames. ### Claim 12 (depends on 8) The method of claim 8, further comprising associating the image pattern with a user account, wherein the image pattern is customized based on the user account. ### Claim 13 (depends on 8) The method of claim 8, wherein the image pattern includes at least one of a barcode and a color pattern. ### Claim 14 A non-transitory computer program product having instructions encoded thereon that when executed by one or more processors cause a process to be carried out, the process comprising: receiving digital content from a server, the digital content including a series of image frames received from a camera of a first device, the series of image frames being generated and displayed by a web browser of a second device, the series of image frames having an image pattern steganographically hidden therein; and rendering, via a video display of the first device, the series of image frames generated and displayed by the web browser of the second device, wherein the image pattern matches a predefined image pattern associated with a user of the second device. ### Claim 15 (depends on 14) The non-transitory computer program product of claim 14, wherein the content is visually perceptible by a human and the image pattern is visually imperceptible by a human when the image frames are rendered sequentially. ### Claim 16 (depends on 14) The non-transitory computer program product of claim 14, wherein the image pattern appears for approximately 1/60th of a second. ### Claim 17 (depends on 14) The non-transitory computer program product of claim 14, wherein the image pattern appears in a single one of the series of image frames. ### Claim 18 (depends on 14) The non-transitory computer program product of claim 14, wherein the process further comprises associating the image pattern with a user account, wherein the image pattern is customized based on the user account. ### Claim 19 (depends on 14) The non-transitory computer program product of claim 14, wherein the image pattern includes at least one of a barcode and a color pattern. ### Claim 20 (depends on 14) The non-transitory computer program product of claim 14, wherein the image pattern appears for at most 24/60th of a second.
