摘要： A computer system generates a first decompressed media stream based on a first compressed media stream. While providing the first decompressed media stream to the presentation device, the computer system receives a content-transition indication to switch to a second decompressed media stream. In response to receiving the content-transition indication, the computer system selects a first transition point in first content corresponding to the first compressed media stream and selects a second transition point in second content corresponding to the second compressed media stream. The second transition point is selected in accordance with a bandwidth available for receiving the second compressed media stream and the first transition point is selected based on the second transition point. The computer system requests the second compressed media stream starting at the second transition point and ceases to provide the first decompressed media stream at the first transition point in the first content.

摘要： A computer system generates a first decompressed media stream based on a first compressed media stream. While providing the first decompressed media stream to a presentation device, the computer system receives a content-transition indication for providing a second decompressed media stream to the presentation device instead of the first decompressed media stream. The content-transition indication corresponds to a request to display the second decompressed media stream starting at a respective point within a predefined portion of the second decompressed media stream. The computer system receives a second compressed media stream corresponding to the second decompressed media stream. In response to receiving the content-transition indication, the computer system generates the predefined portion of the second decompressed media stream and provides a subset of the predefined portion, that does not include content prior to the respective point, to the presentation device instead of the first decompressed media stream.

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 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.

摘要： A computer system generates, using a first codec, a first decompressed media stream based on a first compressed media stream. The computer system provides the first decompressed media stream to a presentation device. While providing the first decompressed media stream to the presentation device, the computer system receives a second compressed media stream corresponding to a second decompressed media stream to be presented by the presentation device and initializes a second codec after the first codec has stopped decompressing the first compressed media stream so that no more than one codec is decompressing compressed media at a time. The computer system generates, using the initialized second codec, the second decompressed media stream and provides the second decompressed media stream to the presentation device instead of providing the first decompressed media stream to the presentation device.

摘要： A computer system receives a first compressed media stream and stores corresponding data in a first compressed buffer. The computer system generates a first decompressed media stream based on the first compressed media stream. While providing the first decompressed media stream to a 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. While continuing to generate the first decompressed media stream using the first compressed buffer, the computer system receives a second compressed media stream corresponding to the second decompressed media stream and stores corresponding data in a second compressed buffer. After storing the data in the second compressed buffer, the computer system provides a second decompressed media stream, based on the second compressed media stream, to the presentation device instead the first decompressed media stream.
