Receiver with a visual program guide for mobile television applications and method for creation
View Patent ↗A method of creating a visual program guide for use on a TDM mobile TV receiver comprises receiving a RF signal associated with a TV channel; demodulating all of the received RF signals associated with the TV channels; decoding all of the demodulated received RF signals corresponding to all the TV channels simultaneously; and creating the visual program guide as a consolidated view of each of the decoded TV channels, wherein the simultaneous decoding of the demodulated received RF signals significantly reduces a power consumption level and a memory utilization level in the receiver.
1. A time division multiplexing (TDM) mobile television (TV) receiver comprising:
an antenna that receives radio frequency (RF) signals associated with TV channels;
a RF front end section directly connected to said antenna;
an analog-to-digital (A/D) converter directly connected to said RF front end section;
a demodulator directly connected to said A/D converter, wherein said demodulator extracts all of the received RF signals associated with the TV channels; and
a video decoder directly connected to said demodulator, wherein said video decoder parses video frames of each TV channel; lowers a visual resolution level of the parsed video frames from said each TV channel according to an available processing power level associated with said video decoder; decodes all of the received RF signals corresponding to the lower visual resolution level of said parsed video frames from said each TV channel simultaneously; and creates a visual program guide comprising a consolidated view of said each TV channel at said lower visual resolution level,
wherein said video decoder comprises processing power that decodes multiple TV channels simultaneously at said lower visual resolution level,
wherein said video decoder comprises memory capabilities that decodes multiple TV channels simultaneously, and
wherein said video decoder lowers a visual resolution level of all parsed video frames except for reference video frames from said each TV channel.
2. The receiver of claim 1 , wherein said lower visual resolution level comprises a reference frame rate level.
3. A time division multiplexing (TDM) mobile television (TV) receiver comprising:
an antenna that receives radio frequency (RF) signals associated with TV channels;
a RF front end section operatively connected to said antenna;
an analog-to-digital (A/D) converter operatively connected to said RF front end section;
a demodulator operatively connected to said A/D converter, wherein said demodulator extracts all of the received RF signals associated with the TV channels, and wherein said demodulator comprises a video parsing block that parses video frames of each TV channel; and lowers a visual resolution level of the parsed video frames except for reference video frames from said each TV channel; and
a video decoder operatively connected to said demodulator, wherein said video decoder decodes all of the received RF signals corresponding to the lower visual resolution level of said parsed video frames from said each TV channel; and creates a visual program guide comprising a consolidated view of said each TV channel at said lower visual resolution level,
wherein said video decoder discards non-reference video frames from said each TV channel,
wherein said video decoder comprises memory that holds said reference video frames of a given TV channel,
wherein said demodulator transfers only said reference video frames to said video decoder, and wherein said video decoder decodes only said reference video frames, and
wherein a lower resolution is determined based on a number of frames that are being dropped.
4. The receiver of claim 3 , wherein the transferring of said reference video frames from said demodulator to said video decoder allows for memory reuse at said demodulator.
5. The receiver of claim 4 , wherein said demodulator comprises memory that stores said reference video frames of only one TV channel.
6. The receiver of claim 3 , wherein said video decoder comprises memory that stores said reference video frames of all said TV channels.
7. A method of creating a visual program guide for use on a time division multiplexing (TDM) mobile television (TV) receiver, said method comprising:
receiving, in said receiver, radio frequency (RF) signals associated with TV channels;
demodulating, in said receiver, all of the received RF signals associated with the TV channels;
decoding, in said receiver, all of the demodulated received RF signals corresponding to all said TV channels simultaneously and according to their time of arrival at said receiver;
parsing, in said receiver, video frames of each TV channel;
lowering, in said receiver, a visual resolution level of the parsed video frames from said each TV channel according to an available processing power level associated with said receiver;
lowering, in said receiver, a visual resolution level of all parsed video frames except for reference video frames from said each TV channel;
decoding, in said receiver, all of said demodulated RF signals corresponding to the lower visual resolution level of said parsed video frames from said each TV channel simultaneously;
scaling, in said receiver, each said TV channel simultaneously;
discarding, in said receiver, non-reference video frames from said each TV channel; and
creating, in said receiver, said visual program guide as a consolidated view of each of the decoded TV channels,
wherein the simultaneous decoding of said demodulated received RF signals reduces a power consumption level and a memory utilization level in said receiver.
8. The method of claim 7 , wherein said lower visual resolution level comprises a reference frame rate level.
