Changing HDMI Content in a Tiled Window

A non-transitory computer-readable storage medium for use in conjunction with an electronic device, the computer-readable storage medium storing a program module that, when executed by the electronic device, causes the electronic device to provide an output data stream by performing one or more operations comprising:

• receiving, via an interface circuit in the electronic device, user-interface activity information associated with a portable electronic device, wherein the user-interface activity information specifies user selection of a content source based on activation of a single command feature, in a user interface, which is associated with the content source;
• providing, via the interface circuit and based on the user selection, a request for first video content having a high-definition format for the content source;
• receiving, via the interface circuit, an input data stream that includes full frames of the first video content associated with the content source;
• generating the output data stream, having a data rate that is less than a threshold value associated with swapping data in the memory and that is compatible with a high-definition multimedia-interface (HDMI) format, which includes frames of scaled first video content and display instructions that specify a first tiled window associated with the scaled first video content, wherein the scaled first video content has the high-definition format and includes component channels, and wherein the scaled first video content corresponds to the first video content;
• and
• providing, via the interface circuit, the output data stream for a display device.

A method for providing first video content, wherein the method comprises:

• by an electronic device:
• receiving, via an interface circuit in the electronic device, user-interface activity information associated with a portable electronic device, wherein the user-interface activity information specifies user selection of a content source based on activation of a single command feature, in a user interface, which is associated with the content source;
• providing, via the interface circuit and based on the user selection, a request for first video content having a high-definition format for the content source;
• receiving, via the interface circuit, an input data stream that includes full frames of the first video content associated with the content source;
• generating the output data stream, having a data rate that is less than a threshold value associated with swapping data in the memory and that is compatible with a high-definition multimedia-interface (HDMI) format, which includes frames of scaled first video content and display instructions that specify a first tiled window associated with the scaled first video content, wherein the scaled first video content has the high-definition format and includes component channels, and wherein the scaled first video content corresponds to the first video content;
• and
• providing, via the interface circuit, the output data stream for a display device.
