Abstract: A method and system including receiving marking information, determining, at least in part, based on the marking information, a plurality of color element additives, adding the plurality of color element additives to at least one color element of a video frame, wherein the at least one color element includes a color element R, a color element G, and a color element B. Related methods and systems are also described.

Abstract: A system for restricting access to encrypted content stored in a consuming device (12) which is part of a network (10) including other devices (14), the system including a content storage medium to store the encrypted content, a secret-share distribution module to distribute secret-shares to the other devices (14), a secret-share receive module to receive the secret-shares from the other devices (14), a secret reconstruction module to form a content decryption input from the secret-shares received by the secret-share receive module, a content decryption module to receive the encrypted content from the content storage medium and the content decryption input from the secret reconstruction module and decrypt the encrypted content using the content decryption input thereby rendering decrypted content, and a content consumer to use the decrypted content, wherein the secret shares distributed to the other devices (14) are in an encrypted format for decryption by the consuming device (12) or the other devices (14).

Abstract: A method for switching from playing a first compressed data segment to playing a second compressed recorded data segment, the method including playing an uncompressed copy of a start of the second compressed recorded data segment upon switching from playing the first compressed data segment, decoding the second compressed recorded data segment from a preceding random access point, the preceding random access point preceding, in the second compressed recorded data segment, a point at which playing is to be switched to the second compressed recorded data segment, stopping the decoding of the second compressed recorded data segment when reaching a point beyond a point currently being played in the uncompressed copy, and switching to playing the second compressed recorded data segment when playing the uncompressed copy of a start of the second compressed recorded data segment reaches the point at which the decoding of the second compressed recorded data segment was stopped.
