Abstract: Embodiments facilitating mixed service use of bonded satellite transponders in communication systems are provided. An apparatus comprises a first multiplexer configured to receive first content from first channels of a first type of channel, a second multiplexer configured to receive second content from second channels of a second type of channel, and a transport stream processor (TSP). The TSP can be configured to output the received first content and the second content to modulators respectively associated with different channels for transmission of the first type of channel and the second type of channel, wherein the different channels are transmitted to a bonded satellite transponders, which transmits to a receiver. In some embodiments, the apparatus can comprise a multiplexer aggregator coupled between the TSP and the first multiplexer and the second multiplexer. The first content can be high bit-rate information and the second content can be lower bit-rate information.

Abstract: A predetermined set of channels from a satellite broadcast are received and tuned in parallel at a head end module of a local area network, which potentially serves a large number of users with electronic devices via multiple wired and/or wireless access points, such as at a college campus or a business center. Each channel of content is transcoded into multiple content streams providing multiple bit-rate options for each channel of content, e.g., using HTTP Adaptive Streaming protocols and/or Scalable Video Coding. The transcoded content streams are packetized and transmitted with respective multicast IP addresses to the access points on the local area network. Electronic devices connected to an access point are able to stream content from any one of the predetermined set of channels by joining one or more corresponding multicasts.

Abstract: A method and apparatus for transmitting a plurality of elementary data streams to a plurality of receivers is disclosed. In one embodiment, the method comprises the steps of generating M data streams comprising K multiplexed elementary data streams in a first entity, transmitting the M data streams to a second entity, generating N transmitter streams from the M data streams in the second entity; and transmitting each of the N transmitter streams to the plurality of receivers using an associated one of N broadcast sub-transmitters.

Abstract: Reference frames are selected for use in a frame reference buffer in a video encoding system, so as to provide long term prediction of motion in video sequences. Candidate reference frames are characterized by characteristic vectors. From the candidate reference frames, a number of reference frames are maintained in the frame buffer so as to obtain a specified distribution of the characteristic vectors over a vector space. Frames are selected for use in encoding a current frame based on the characteristic vector of the current frame and the reference frames in the frame buffer.

Abstract: A video system and process in which a series of video frames are encoded for fast forward and/or fast reverse playback, wherein a subset of frames are encoded as reference frames that have a hierarchical relationship with each other. The reference frames are I frames and predicted frames, such as P, B, or IDR frames.

Abstract: Motion vectors for encoding a predicted frame relative to a reference frame are determined from a phase correlation of corresponding regions of the predicted frame and reference frame. Peaks in the phase correlation are identified, and the location of the peaks are used as candidate motion vectors. From this limited set of candidate motion vectors, the best motion vectors for predicting blocks within each region can be readily identified.

Abstract: An apparatus and method for dynamically varying the frame rate of an image sequence is disclosed. In one embodiment, the image sequence is encoded and stored at different frame rates (e.g., 30, 25, 20 fps and so on). Alternatively, only the motion information, e.g., motion vectors, for the other frame rates are stored.
