FOX 5 San Diego –High-Definition Media Specifications

KSWB uses a secure file transfer solution (SFTP). Contact your account manager or KSWB continuity for address and password.

Create a new folder with the name of the client or advertiser and upload files into folder. Files older than 30 days will be removed.

SFTP, which stands for SSH File Transfer Protocol, or Secure File Transfer Protocol, is a separate protocol packaged with SSH that works in a similar way over a secure connection. The advantage is the ability to leverage a secure connection to transfer files and traverse the file system on both the local and remote system. In almost all cases, SFTP is preferable to FTP because of its underlying security features and ability to piggyback on an SSH connection.

A: Yes!  Spots on sub-channels air in 4:3 Standard Definition but can be submitted in HD or SD.  Just be aware that HD spots for AntennaTV and ThisTV will be cropped to fit the 4:3 television aspect ratios and must be graphics and titles should be 4:3 safe.
