Abstract: Disclosed are systems and methods for creating a trick mode stream. A digital home communication terminal (DHCT) comprises a network interface, a storage medium, at least one memory storing program code; and at least one processor programmed by at least the program code. The network interface is in communication with a second DHCT. The program code enables the DHCT to: select a first encoded picture frame from a recorded video stream on the storage medium; retrieve a first sequence of transport packets encapsulating the first picture frame; create a first transport packet containing a first client control packet associated with the first picture frame; and transmit, to a video decoder in the second DHCT, a trick mode stream comprising the first transport packet followed by the first sequence of transport packets. The first client control packet comprises the size of the first picture frame and a decoder command.

Abstract: Tuning a radio oscillator frequency to a reference frequency is disclosed. A radio oscillator is set using a predetermined value loaded into an adjustment bit array. A highest selected bit is selected to be used in locating a final tuned value for the adjustment bit array. The final tuned value is determined by successively setting a selected bit starting with the highest selected bit in the adjustment bit array. And, the selected bit value in the final tuned value is determined using a measurement of the radio oscillator frequency and its relation to a reference frequency.
