System and method for advancing to a predefined portion of a decompressed media stream

A computer system, the computer system comprising:

• one or more processors;
• and
• memory storing one or more programs, wherein the one or more programs are stored in the memory for execution by the one or more processors, the one or more programs including instructions for:
• generating, using a first codec, a first decompressed media stream based on a first compressed media stream;
• providing the first decompressed media stream to a presentation device;
• while providing the first decompressed media stream to the presentation device:
• receiving 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, wherein the content-transition indication corresponds to a request to display the second decompressed media stream starting at a respective point in the second decompressed media stream;
• and
• receiving a second compressed media stream corresponding to the second decompressed media stream;
• and
• in response to receiving the content-transition indication:
• initializing a second codec after the first codec has stopped decompressing compressed media so that no more than one codec is decompressing compressed media at a time;
• generating, using the second codec, the second decompressed media stream;
• and
• providing the second decompressed media stream, without content prior to the respective point, to the presentation device instead of providing the first decompressed media stream to the presentation device.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by a computer system with one or more processors, cause the computer system to:

• generate, using a first codec, a first decompressed media stream based on a first compressed media stream;
• provide the first decompressed media stream to a presentation device;
• while providing the first decompressed media stream to the presentation device:
• receive 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, wherein the content-transition indication corresponds to a request to display the second decompressed media stream starting at a respective point in the second decompressed media stream;
• and
• receive a second compressed media stream corresponding to the second decompressed media stream;
• and
• in response to receiving the content-transition indication:
• initialize a second codec after the first codec has stopped decompressing compressed media so that no more than one codec is decompressing compressed media at a time;
• generate, using the second codec, the second decompressed media stream;
• and
• provide the second decompressed media stream, without content prior to the respective point, to the presentation device instead of providing the first decompressed media stream to the presentation device.
