Abstract: An apparatus performs a data caching operation responsive to a channel change event which reduces channel change times. According to an exemplary embodiment, the apparatus includes a cache memory operative to cache an incoming data stream responsive to a channel change command. A processor is operative to find program specific information included within the incoming data stream. A decoder is operative to decode the cached data stream responsive to the processor finding the program specific information.

Abstract: The disclosed embodiments relate to a system and method for selecting a signal input. More specifically, there is provided a receiver comprising an Ethernet input, a video input, and a selection device coupled to the Ethernet input and the video input and configured to select either the Ethernet input or the video input based on the application of a selection rule, wherein the receiver is configured to utilize the selected input to receive a signal for display.

Abstract: The disclosed embodiments relate to a system and method for advertising the availability of a software upgrade. More specifically, there is provided a method comprising determining a version of software that supports a set top box, adding information indicative of whether the set top box is running the supporting version of the software to a packet, wherein the packet contains data representative of a satellite service, and transmitting the packet to the set top box.

Abstract: A method and apparatus is presented for providing faster tuning of a digital television channel. Specifically, the present invention is directed to a digital television receiver including a tuner, at least one demodulator, a detachable security module such as a point of deployment (POD) module, a transport demultiplexer, and a microprocessor having a cache or memory device for storing “conditional access program map table” (CA_PMT) information. The cache or memory device is used to store the CA_PMT for each channel, so that upon a channel change requested by a user, the receiver may extract the stored CA_PMT from the cache rather than wait for the full program map table (PMT) to be transmitted by the broadcaster (see FIG. 2). In this way, the time required to display a requested digital television channel is significantly reduced.

Abstract: A method and a system for performing trick mode features in a personal video recorder without introducing a channel change delay during normal viewing. The method includes the steps of recording a video source signal and concurrently bypassing the video source signal to a display device, without experiencing any buffering delay associated with the recording step. During trick mode operation the bypassing step can be automatically terminated and a recorded version of the video source signal can be substituted and sent to the display. The bypassing step further can include substituting, without any buffering delay, an alternate video source signal in response to a user selection of an alternate video source signal channel. A user notification can be generated to acknowledge receipt of a trick mode command. The user notification can be terminated once the step of substituting the recorded version of the video source signal has been completed.
