摘要： [Object] It is desired to provide a technology capable of suppressing the production cost of a system in which a video signal is transmitted via a plurality of transmission paths. [Solution] Provided is a frame generation apparatus including: an image division section configured to, in a case where a horizontal-direction pixel number in a video signal is set to integers of 0 to N−1 and a vertical-direction line number in the video signal is set to integers of 0 to M−1, perform an operation of dividing a pixel group included in a line of which the vertical-direction line number is 2m and a pixel group included in a line of which the vertical-direction line number is (2m+1) on a basis of color format information of the video signal, for all integers m satisfying 0≤m≤(M/2)−1, and thereby obtain a plurality of divided signals; and a frame generation section configured to generate a plurality of frames individually including the plurality of divided signals.

摘要： A computer system receives a content-transition indication to provide a second decompressed media stream to a presentation device instead of providing a first decompressed media stream. In response to receiving the content-transition indication, the computer system ceases to receive a first compressed media stream corresponding to the first decompressed media stream and continues to provide the first decompressed media stream to the presentation device using first buffered data. The computer system selects a transition point for a second compressed media stream, corresponding to the second decompressed media stream, based on a quantity of data of the second compressed media stream to be buffered. While continuing to provide the first decompressed media stream to the presentation device using the first buffered data, the computer system receives and buffers the second compressed media stream starting at the transition point. The computer system provides the second decompressed media stream to the presentation device.

摘要： A method includes the following operations: (1) executing an application that that generates a series of video frames using a graphics processing unit (GPU); (2) determining that a first video frame in the series has been completely written to a back buffer; (3) determining whether a current scan line of a second video frame is outside of a specified region, where the second video frame is stored in a front buffer and is being read out line by line following receipt of a monitored synchronizing signal; (4) presenting the first video frame to the front buffer without frame transitions, if the current scan line is outside of the specified region and is in a vertical blanking interval (VBI); and (5) presenting the first video to the front buffer with frame transitions, if the current scan line is outside of the specified region and is not in the VBI.

摘要： A computer system generates a first decompressed media stream based on a first compressed media stream and provides the first decompressed media stream to a presentation device. While providing the first decompressed media to the presentation device: the computer system receives a content-transition indication indicating that a second decompressed media stream is to be provided to the presentation device instead of the first decompressed media stream. The computer system stores first buffered data corresponding to the first decompressed media stream and receives a second compressed media stream corresponding to the second decompressed media stream. After receiving the second compressed media stream, the computer system provides the first buffered data corresponding to the first decompressed media stream to the presentation device while preparing to generate the second decompressed media stream, and after preparing to generate the second decompressed media stream, provides the second decompressed media stream to the presentation device.
