Abstract: An integrated approach is provided to running web applications with various compatibilities that do not require third-party extensions or sacrifice user experience. When a page of an application incompatible with a first browser is to be executed, an instance of a second browser with which the page is compatible is separately invoked and/or executed without opening a window for that second browser. Instead, the second browser opens a page within the window of the first browser. Moreover, rendering and/or contextual information for a page opened via the second browser is provided to the first browser. Such information is utilized by the first browser to provide a visual experience to the user in which the web page is being hosted by the first browser, even though it is in fact being hosted by the second browser.

Abstract: Techniques and tools for reducing latency in video encoding and decoding by constraining latency due to reordering of video frames, and by indicating the constraint on frame reordering latency with one or more syntax elements that accompany encoded data for the video frames. For example, a real-time communication tool with a video encoder sets a syntax element that indicates a constraint on frame reordering latency, which is consistent with inter-frame dependencies between multiple frames of a video sequence, then outputs the syntax element. A corresponding real-time communication tool with a video decoder receives the syntax element that indicates the constraint on frame reordering latency, determines the constraint on frame reordering latency based on the syntax element, and uses the constraint on frame reordering latency to determine when a reconstructed frame is ready for output (in terms of output order).

Abstract: An integrated circuit chip can provide protection with registers of a register file. A processor can be part of general or security-oriented (e.g., root-of-trust (RoT)) circuitry. In described implementations, the processor includes multiple register blocks for storing multiple register values. The processor also includes multiple integrity blocks for storing multiple integrity codes. A respective integrity block is associated with a respective register block. The respective integrity block can store a respective integrity code that is derived from a respective register value that is stored in the respective register block. The integrity code can enable detection or correction of one or more corrupted bits in the register value. An integrity controller of the processor can monitor the register value regularly or in response to an access by an execution unit. The controller can take a protective action if corruption is detected. This enables information protection to extend to processor execution units.
