In one aspect, an example method includes (i) providing, by a playback device, replacement media content for display; (ii) determining, by the playback device, that a remote control transmitted to the playback device an instruction configured to cause a modification to operation of the playback device while the playback device displays the replacement media content; (iii) determining, by the playback device based on the instruction, an overlay that the playback device is configured to provide for display in conjunction with the modification; (iv) determining, by the playback device, a region within a display of the playback device corresponding to the overlay; and (v) modifying, by the playback device, a transparency of the region such that the overlay is visible through the replacement media content when the playback device provides the overlay for display.

Responsive to detection of remote control signals that modify operation of the playback device

In one aspect, an example method includes (i) providing, by a playback device, replacement media content for display; (ii) determining, by the playback device that while the playback device is displaying the replacement media content a remote control transmitted an instruction to a media device that provides media content to the playback device; (iii) determining, by the playback device, a playback-modification action corresponding to the instruction and the media device; and (iv) modifying, by the playback device, playback of the replacement media content in accordance with the playback-modification action.

Modifying playback of replacement content responsive to detection of remote control signals that control a device providing video to the playback device

One high-level aspect of a content-modification system and related methods may involve facilitating content modification by a content-presentation device of received broadcast content in a controlled manner, while under circumstances in which some events that can impact timing may be unpredictable. In particular, certain operations by a content-presentation device may involve matching received content with specific expected content as determined by one or another component of the content-modification system, in order to confirm proper conditions are met for the content-presentation device to proceed with, or continue, content-modification operations. It can happen the matching procedure becomes subject or susceptible to timing irregularities, or jitter. In some instances, jitter may impact the ability to derive the benefits of content modification. Accordingly, example embodiments herein are directed to systems and method for compensation and/or mitigating the effects of jitter.

Modifying playback of replacement content responsive to detection of remote control signals that modify operation of the playback device

In one aspect, a method for use in connection with a content-presentation device including a first input buffer, a second input buffer, and an output buffer, wherein the content-presentation device is configured such that content from either the first input buffer or the second input buffer can be communicated to the output buffer, includes: (i) receiving, from the content-presentation device, an identifier associated with the content-presentation device; (ii) using mapping data to map the received identifier to a baseline input-to-output delay, which represents a time-period between when content is input into the first input buffer and output by the output buffer; and (iii) transmitting, to the content-presentation device, the mapped baseline input-to-output delay to the content-presentation device to facilitate the content-presentation device (a) determining an input-buffer switching delay, and (b) using the determined input-buffer switching delay to facilitate performing a content-modification operation.
