Video display method
First Claim
1. A method comprising:
- requesting, by a mobile device, a web page from a first server, the web page including an identification of content located on a second server;
requesting, by the mobile device, the identified content from the second server;
receiving, by the mobile device, in response to the request for the identified content from the second server, a configuration script, an audio file, and a composite image as separate files, the composite image comprising a plurality of still images obtained from a video sequence and arranged in a multiple row and multiple column array, the audio file comprising audio extracted from the video sequence, the mobile device including a processor;
creating, by the processor, a viewport, the viewport being embedded in the web page, wherein dimensions of the viewport are equal to dimensions of a first still image of the plurality of still images;
displaying the first still image in the viewport by copying the first still image as a bitmap onto a canvas;
starting a timer with a duration based on a frame rate between the first still image and a second still image of the plurality of still images to follow the first still image;
in response to the timer timing out, automatically displaying the second still image in the viewport by copying the second still image as a bitmap onto the canvas;
repeating starting of the timer with the duration based on one or more frame rates included in the configuration script and displaying of the plurality of still images including displaying each of the plurality of still images in the viewport in sequence; and
synchronizing and playing the audio file concurrently with the displaying of each of the plurality of still images, wherein each of the plurality of still images is displayed according to the one or more frame rates;
wherein;
each complete row of the composite image is created from a fixed duration of the video sequence; and
the displaying of each of the plurality of still images uses only resources supported by a web browser on the mobile device and does not invoke a native video player on the mobile device.

Abstract
A method for video playback uses only resources universally supported by a browser (“inline playback”) operating in virtually all handheld media devices. In one case, the method first prepares a video sequence for display by a browser by (a) dividing the video sequence into a silent video stream and an audio stream; (b) extracting from the silent video stream a number of still images, the number of still images corresponding to at least one of a desired output frame rate and a desired output resolution; and (c) combining the still images into a composite image. In one embodiment, the composite image having a number of rows, with each row being formed by the still images created from a fixed duration of the silent video stream. Another method plays the still images of the composite image as a video sequence by (a) loading the composite image to be displayed through a viewport defined the size of one of the still images; (b) selecting one of the still images of the composite image; (c) setting the viewport to display the selected still image; and (d) setting a timer for a specified time period based on a frame rate, such that, upon expiration of the specified time period: (i) selecting a next one of the still images to be displayed in the viewport, unless all still images of the composite image have been selected; and (ii) return to step (c) if not all still images have been selected.
