AV server and AV server system

An AV server system comprising:

• a plurality of AV servers, each of which is configured to have an Internet Protocol (IP) input-output port for connecting to another AV server that is independent from an input-output port to an outside of the AV server system;
• and
• system circuitry configured to:
• control the plurality of AV servers;
• store information relevant to AV clip data recorded in the plurality of AV servers and AV clip data input to the plurality of AV servers;
• and
• perform frame synchronization between the plurality of AV servers,
• wherein the plurality of AV servers include at least a predetermined AV server to which raw data of a high frame rate is inputted from a single-chip camera, and
• the predetermined AV server of a first AV server system, the predetermined AV server including circuitry configured to:
• support a plurality of types of decoders for decoding a plurality of different codecs;
• perform a first compression encoding process on the raw data of the high frame rate, obtain first AV clip data from the raw data that is compression encoding processed, and write the first AV clip data in a storage;
• read the first AV clip data from the storage and perform a compression decoding process on the first AV clip data to obtain the raw data of the high frame rate, perform a demosaic process on the raw data of the high frame rate obtained from the compression decoding process to obtain video data of the high frame rate, delay outputting the video data of the high frame rate from the demosaic process by a constant value that is associated with the types of decoders, after the delay, perform a second compression encoding process on the video data of the high frame rate to obtain second AV clip data, and write the second AV clip data in the storage;
• and
• read the second AV clip data from the storage and transmit the second AV clip data to a second AV server system that is different from the first AV server system.
