A transcoder includes a demultiplexer that demultiplexes a video signal into a moving image stream, an audio stream and a subtitle stream. A stream probe generates stream format identification data based on the video signal. A transcoder configuration module generates hardware/software configuration data based on the stream format identification data. The hardware/software configuration data configures a plurality of hardware transcoders and the processing device to operate to generate a transcoded video stream, a transcoded audio stream and processed subtitle stream via selected hardware and software blocks. A remultiplexer generates the processed video signal by remultiplexing the transcoded video stream, the transcoded audio stream and the processed subtitle stream, based on the hardware/software configuration data.


A video processing device for decrypting a compressed video signal includes a key storage device for storing at least one decryption key. An decryption processing device retrieves the at least one decryption key from the key storage device, and decrypts an encrypted elementary bit stream into at least one elementary bit stream, wherein first portions of the encrypted elementary bit stream are encrypted and second portions of the encrypted elementary bit stream are unencrypted.


Aspects of the subject disclosure may include, for example, a system that includes a signal interface configured to receive a plurality of video signals from a corresponding plurality of video cameras. A surveillance processor is configured to process the plurality of video signals and to recognize at least one person in at least one of the plurality of video signals and an emotional state corresponding to the at least one person and that generates surveillance data corresponding to the at least one person, based on the emotional state corresponding to the at least one person. Other embodiments are disclosed.


Aspects of the subject disclosure may include, for example, a system that includes a video codec configured to generate a processed video signal based on the image sequence. A photo generation module is configured to recognize an object of interest in the image sequence and generate photo data from a selected image in the image sequence that includes the object of interest. Other embodiments are disclosed.


Aspects of the subject disclosure may include, for example, a system receives indexing data delineating a plurality of program segments in a video signal that each include a sequence of images of the video signal. The indexing data further indicates content contained in the plurality of program segments. A digest generator generates digest data associated with the video signal based on the indexing data, wherein the digest data indicates a plurality of digest segments that constitute a noncontiguous subset of the video signal. Other embodiments are disclosed.
