摘要： An entropy decoding module can be used in a video decoder that decodes a stream of video data from a first buffer. An entropy decoding interface includes a second buffer. A load controller automatically fetches the video data from the first buffer for storage in the second buffer. A search engine searches the video data stored in the second buffer for at least one bit pattern. A processing module retrieves the video data from the second buffer for entropy decoding.

摘要： A processing system includes an interface for receiving application data at the processing system corresponding to an application, the application data including authentication data. A one-time programmable memory stores at least one application key. A processing module executes an operating system that includes a security routine to authenticate the application data based on the authentication data and the at least one application key. The security routine permits the execution of the application by the processing module when the authentication data is authenticated, and prevents the execution of the application by the processing system when the authentication data is not authenticated.

摘要： A multimedia program type of a received multimedia data is determined. Based on the determined multimedia program type, a peak bit rate limit and/or an average bit rate limit are determined. In instances where a transrated version of the multimedia data is to be stored, a remaining storage capacity of a storage device is determined and the peak bit rate limit and/or the average bit rate limit can be adjusted based on the remaining storage capacity. The multimedia data then is transrated to generate transrated multimedia data that has a peak bit rate that does not exceed the selected peak bit rate limit and/or having an average bit rate that does not exceed the selected average bit rate limit. The transrating of the multimedia additionally can include the application of rule sets based on content characteristics. After transrating, the multimedia data can be transmitted via a network to a destination multimedia device, stored locally for subsequent use, or a combination thereof.
