Abstract:
1. A method for video decoding, the method comprising: determining whether a received encoded bitstream is encoded with a first type of video compression standard that uses reference frames and non-reference frames or a second type of video compression standard that uses reference frames and non-reference frames; decompressing a portion of the received encoded bitstream with at least one decompression engine, thereby resulting in a reconstructed output stream; writing the reconstructed output stream into a buffer memory; applying at least one filter to the reconstructed output stream while the reconstructed output stream is stored in the buffer memory when the encoded bitstream was encoded with the first type of video compression standard, thereby resulting in a filtered reconstructed output stream; motion compensating another portion of the received encoded bitstream with the at least one decompression engine, from the filtered reconstructed output stream when the encoded bitstream was encoded with the first type of video compression standard; motion compensating another portion of the received encoded bitstream with the at least one decompression engine, from the reconstructed output stream when the encoded bitstream was encoded with the second type of video compression standard; and applying at least one filter to the reconstructed output stream by a display engine while the display engine prepares the reconstructed output for display when the encoded bitstream was encoded with the second type of video compression; processing a reconstructed output stream using at least one filter when the received encoded bitstream is encoded with a first type of video compression standard that uses reference frames and non-reference frames; processing the reconstructed output stream without using said at least one filter when the received encoded bitstream is encoded with a second type of video compression standard that uses reference frames and non-reference frames; and transferring said processed reconstructed output stream using said configured at least one filter to a display engine when the bitstream is encoded with the second type of video compression standard.
