Abstract
The subject matter of this specification can be implemented in, among other things, a method of decoding video data that includes decoding compressed input video data using a first entropy coding technique to obtain first decoded data. The method further includes re-encoding the first decoded data using a second entropy coding technique that is different from the first entropy coding technique to obtain re-encoded data. The method further includes storing the re-encoded data in a storage device. The method further includes decoding the re-encoded data using the second entropy coding technique to obtain second decoded data.
