    摘要: This invention discloses an intra-frame complexity based dynamic GOP system and method for the encoding of MPEG-2 video streams. The present invention may be used as a rate control tool to improve video quality. The selective insertion of low complexity I frames in scene changes such as fades is disclosed. It is disclosed that the selective use of I frames in certain scene change situations can improve encoder performance, particularly when encoding at a low bit rate.

    摘要: A dynamic watermark generation method and system in which the dynamic watermark may have a default length or a shorter length, and wherein the dynamic watermark is generated to have the determined length. The dynamic watermark is a locally-unique code that is used as an index to a database entry that identifies the subscriber that requested the media asset. In some instances, the entry may include a timestamp, a subscriber device identifier such as a MAC address or IP address, a subscriber identifier or ID number, and a media asset identifier such as a static ID. The static ID may include a code that indicates whether the dynamic watermark is of a default length or shorter. The length of the dynamic watermark may be partly based upon projected audience size for the requested media asset.

    摘要: A system, device and method for service insertion during a video display. A client device detects a video request input, and in response, selects and initiates an advanced service asset while the player buffers the requested video data. The output of the player is displayed in a background field while the media display data of the advanced service asset is displayed in a foreground field. The player display data may be brought to the foreground after a preset time or when the player is ready to display the requested video.

    摘要: A method for alarm event notification from a server system in relation to a premises such as a home or building. The server system acts as a centralized monitoring and notification security system for monitoring of the premises and receiving an alarm event from an on-premises monitoring system. The method includes: receiving in a server system an alarm event in relation to the premises, determining a presence status of a client application, generating a message in relation to the alarm event, and sending the message to the client application having the presence status of being present. The message may be generated to include message content which varies in dependence of capabilities of the client application having the presence status of being present.
