 firewall 203 opens a HTTPS session with the server 205 and transmits the request 209 to the server 205. Hence, the request 209 has bypassed the IDS 202.
This security architecture is typically employed in a corporate environment. A corporate entity needs to protect its systems from being infected and/or prevent access to its systems by external and/or internal malignant elements while still enabling its employees to access resource beyond its local area network. The corporate entity also needs to control the types of resources or material that enters its network at the request of its employees. Therefore, a corporate entity employs both a firewall with proxy support and an intrusion detection system to protect its network from external hacking and internal violations of its computer use policy. Unfortunately, as shown in FIG. 2, an IDS can be bypassed with encryption.
Service provides also used another mechanism with a security flaw to accommodate users. In order to avoid agitating users with error messages and increasing latency, service providers allowed a pass through for messages that were not encrypted. For this mechanism, a content switch is configured to listen for traffic on both ports 80 and 443. Traffic received on port 80 is forwarded to the corresponding servers while traffic received on port 443 is decrypted. Hence, users are not inconvenienced with error messages and increased latency, but users were possibly transmitting sensitive information without encryption. 1. Field of the Invention
The present invention relates to a high-rate coding device for performing high-rate coding of an input signal, a video signal recording and reproduction apparatus for recording and reproducing data obtained by the high-rate coding and to a video signal transmitting apparatus for transmitting data obtained by the high-rate coding. (In this specification, high efficiency coding and high efficiency decoding are expressed as "high-rate coding" and "high-rate decoding".)
2. Description of the Related Art
Video signal recording apparatuses for digitally recording a video signal are generally classified into two types: One type of apparatuses compress a standard-definition (SD) TV signal to 25 Mbps by performing intraframe coding for recording. The other type of apparatuses compress a high vision signal to 50 Mpbs for recording. In these types of apparatuses, the type of video signals usable for input and output and the quality of the signals obtained are limited. It is extremely difficult to record and reproduce a video signal which is of a different type from the signal which are input to or output from devices in the video signal recording apparatus without significantly changing the recording and reproducing processing.
For example, in a video signal
firewall 203 opens a HTTPS session with the server 205 and transmits the request 209 to the waiter 205. therefore, the request 209 has bypass the IDS 202. 
 This security architecture is typically employed in a bodied environment. A corporate entity needs to protect its systems from being infect and/or prevent access to its systems by external and/or home malignant elements while still enable its employees to access resource beyond its local area network. The corporate entity besides needs to control the type of resources or material that embark its network at the request of its employees. Therefore, a bodied entity employs both a firewall with proxy support and an invasion detection arrangement to protect its network from external hacking and internal violations of its computer use policy. Unfortunately, as prove in FIG. 2, an IDS can be bypassed with encryption. 
 Service provides also used another mechanism with a security defect to suit users. In order to avoid agitating users with error messages and increasing latency, military service providers allowed a crack through for message that were not encrypted. For this mechanism, a content substitution is configured to heed for traffic on both ports 80 and 443. Traffic welcome on port 80 is forwarded to the corresponding servers while traffic received on port 443 is decrypted. Hence, users are not inconvenienced with mistake messages and increase latency, but users were possibly transmitting sensitive information without encoding. 1. Field of the Invention
