The present invention relates to systems and methods for combining compressed video data encoded or received with different resolutions. The present invention combines the compressed video data from the two separate bitstreams without decoding and re-encoding each bitstream. To do so, the present invention determines which compressed video bitstream has video data with a lower resolution, and applies a tiling process that alters the low resolution compressed video data such that it may be displayed at a high resolution.

A packet schedule timestamp is provided. A schedule information packet includes a packet schedule timestamp that represents the relative timing of data packets in a particular bitstream of a multiplexed transport stream. The schedule information packet further provides information about the timing of packets within a bitstream or multiple bitstreams before actual packet arrivals. Look-ahead processing techniques are provided to improve the efficiency of compressed bitstream storage and delivery, such as program stream to transport stream conversion and statistical multiplexing. The packet schedule information can be inserted into the bitstream it describes for transmission or storage with it. Other features, such as timing reconstruction, are also provided. The packet schedule information can be used to reconstruct the timing of the transport packets to their original state.

Compressed digital video bitstreams are segmented into video segments. A staging processor performs transrating on the original video segments and generates several transrated output video segments. The output video segments are combined into a video block for further distribution. A bit rate switch selects among the transrated video segments from the video block to provide a statistically multiplexed output bitstream. The bit rate switch can also select local stream segments, such as advertisements, for content insertion purposes. A transprocessor including multiple encoder output features is also provided.

Statistical remultiplexing of compressed video segments

A method for facilitating the search of video content by matching fingerprint data extracted from a given video content with existing video fingerprint data already stored in the database. The system consists of systems for extracting fingerprint from the video content, the database for storing plurality of fingerprint data entries from known video content segments and systems for comparing between the fingerprint data obtained from the video content with the fingerprint data entries obtained from the fingerprint database. Once a match is identified, the video content associated with the matched fingerprint in the database is said to be identified by the information in the database associated with the match. The information referenced from the database includes archived video information.
