摘要： In one embodiment, a consumer device is assigned, at a broadcast headend to one of at least two groups of consumer devices, the two groups including a first group of consumer devices which is required to play content of a second type in order to view content of a first type and a second group of consumer devices which is not required to play content of the second type in order to view content of the first type. A video broadcast stream is sent from the broadcast headend to the consumer device, the video broadcast stream comprising content of the first type sent associated with a first packet ID (PID) and content of the second type sent associated with a second PID, wherein the first PID and the second PID are processed at the consumer device at the same time. An entitlement management message (EMM) is sent from the broadcast headend to the consumer device according to its group of consumer devices, the EMM being of one of a first type of EMM for devices of the first device type and a second type of EMM for devices of the second device type. An entitlement control message (ECM) stream is sent from the broadcast headend to the consumer device, the ECM stream including comprising three types of ECMs: ECM_P_i_start which enables the consumer device to produce a control word which decrypts a first portion of the content of the first type; ECM_A_(i-1) which enables the consumer device to produce a control word which decrypts content of the second type; and ECM_P_i_rest which enables the consumer device to produce a control word which decrypts a second portion of the content of the first type. Related hardware, systems and methods are also described.

摘要： In one embodiment, a video stream is received, and a spatially distinct region of a frame in the received video stream to be modified is identified, the spatially distinct region of the frame being encoded separately from any other region in the frame. A segment of the spatially distinct region of the frame to be modified is extracted. The extracted segment of the spatially distinct region is modified. The extracted segment of the spatially distinct region into a single-segment spatially distinct region is encoded. A network abstraction layer (NAL) header is associated with the encoded single-segment spatially distinct region. The encoded single- segment spatially distinct region and its associated NAL header is inserted into the received video stream following the identified spatially distinct region of the frame to be modified. Related methods, systems and apparatus are also described.
