Abstract:
1. A method for buffering Moving Picture Exert Group (MPEG) digital signals of at least a unicast or a multicast data streams in a home communication terminal, the method comprising the steps of: reading data into a decoder buffer at a first data rate; obtaining a first occupancy level in said decoder buffer, wherein said first occupancy level is a level at which the decoder buffer reaches a key frame of MPEG; responsive to determining that the data in the decoder buffer includes the key frame and responsive to obtaining the first occupancy level, outputting data from said decoder buffer at a second data rate, wherein said second data rate is less than said first data rate, and displaying images on a display using data output at said second rate; obtaining a second occupancy level in said decoder buffer; and responsive to obtaining the second occupancy level, outputting data from said decoder buffer at a third data rate, wherein said third data rate is greater than said second data rate, and displaying images on the display using data output at the third data rate; wherein a channel alternation occurs as a result of said home communication terminal outputting said digital signals from said decoder buffer prior to said decoder buffer reaching said second occupancy level at said second data rate.
