Burst efficient fast program acquisition

摘要

Various methods, systems, and apparatuses can be used to perform burst efficient fast program acquisition. In some implementations, a burst efficient fast program acquisition system can operate to remove unused B-frame thereby reducing the bandwidth required for a fast burst. In other implementations, the burst efficient fast program acquisition system can decode the fast burst, identify the video frames needed for reassembly, and encode a truncated group of frames for fast burst transmission. A burst efficient fast program acquisition system can also use pre-calculated streamlined burst fast burst in conjunction with program prediction methods such as adjacent program and frequently viewed program thereby further reducing the latency associated with IPTV program acquisitions.

主权项

1. A burst efficient fast program acquisition system, comprising:
a network interface operable to receive an incoming signal comprising a program selection request; a system processor coupled to the network interface, the system processor operable to generate a fast burst of a requested program comprising video frames to enable a user to view video images when the program selection request is made during a transmission of a group of pictures, the system processor being further operable to streamline the fast burst by identifying and removing only unused B-frames, the identifying and removing occurring based upon the system processor decoding the fast burst, truncating the fast burst to generate a truncated group of fast burst frames that does not include the unused B-frames, and recoding the truncated group of fast burst frames; and wherein the network interface is further operable to transmit a single B-frame burst streamlined fast burst, based on the recoding of the truncated group of fast burst frames.
