Abstract

A system capable of receiving a television signal and telephone signal on a mobile communication terminal. In particular, the system is capable of displaying each television broadcast on a monitor of the mobile communication terminal by receiving the video and audio signal, decoding it, and outputting it to the monitor of the mobile communication terminal. In addition, the system can transmit an EPG (Electronic Program Guide) data corresponding to a subscriber request and a selected broadcasting program in real time.

Claims

1. A subscriber terminal comprising:

a transceiver to receive additional data, as well as digital video and audio data via a mobile telecommunications network through a transmission channel allotted by the mobile telecommunications network,

wherein the digital video and audio data complying with a digital television broadcasting standard was encoded into a format compatible with transmission over the transmission channel of the mobile telecommunications network upon controlling an encoding rate of to comply with a transmission rate of the mobile telecommunications network;

a user input unit to receive input commands from the user;

a video processor to process the received digital video;

an audio processor to process the received audio data; and

a main processor cooperating with the transceiver, the user input unit, the video processor and the audio processor such that the digital video and the audio data received from the digital broadcast provider via the mobile telecommunications network are reproduced to the user.

2. The terminal of claim 1, wherein the transceiver additionally receives EPG (Electronic Program Guide) data via the mobile telecommunications network, the EPG data allowing for broadcast schedule searching using keywords, program titles, actor names and other program related concepts.

3. The terminal of claim 2, further comprising:

an output unit that cooperates with the main processor to display the digital video and provide the audio data to the user, and also output the received EPG data to allow user selection thereof.

4. The terminal of claim 1, wherein at least the transceiver, the user input unit, and the main processor further cooperate to perform at least one of subscriber billing, subscriber rights or password management, and subscriber certification via the mobile telecommunications network.

5. The terminal of claim 1, wherein the format compatible with transmission over the transmission channel of the mobile telecommunications network comprises at least one of a ATSC standard, a DVB standard, a 3GPP standard, an OFDM standard, an MPEG-2 standard, an MPEG-4 standard, an H.26L standard, an H.263 standard, an H.26X standard, a WAP (Wireless Application Protocol) standard, a PSIP (Program Stream Internet Protocol) standard, a HDML (Handheld Device Mark-up Language) format, a TTML (Tagged Text Mark-up Language) format, HDTP (Handheld Device Transport Protocol) format, an ITTP (Intelligent Terminal Transfer Protocol) format, MHEG/XHTML (Multimedia and Hypermedia Expert Group/XHyper-Text Mark-up Language) format.

6. The terminal of claim 1, wherein the additional data is related to at least one of program system information (PSI), service guide information, subscriber billing, subscriber password and access rights management, and subscriber certification.

7. The terminal of claim 1, further comprising:

a storage device that supports data storage techniques based upon at least one of a striping method and time-based data burst procedures using I-Frame value processing, Bit Rate Drop processing, and Macro Block and Intra/Inter compensation processing.

8. A mobile phone comprising:

a radio frequency transceiver configured to transmit and receive signals and information;

a digital signal processor configured to perform demodulating, multiplexing and decoding of digital video and audio data, and to provide multiplexed output data and decoded output data;

a storage configured to receive and store information from the digital signal processor;

a data processor/converter configured to receive the decoded output data from the digital television signal processing unit, to perform further decoding and protocol conversion thereon, and to provide protocol-converted output data; and

a transcoder/transmitter configured to receive the multiplexed output data from the digital signal processor, to retrieve the information stored in the storage, and to receive the protocol-converted output data from the data processor/converter, and configured to perform transcoding, media synchronization, wireless data protocol processing and rate control thereon to provide wireless streaming outputs to a user of the mobile phone who receives and reproduces the digital video and audio data via the mobile phone that is compatible with a mobile telecommunications network.

9. The mobile phone of claim 8, wherein the radio frequency transceiver, the digital signal processor, the storage, the data processor/converter, and the transcoder/transmitter further cooperate to support operations for a voice call mode and a digital television signal reception mode.

10. The mobile phone of claim 8, further comprising:

a digital television signal tuner component cooperating with the radio frequency transceiver for receiving digital video and audio data from a broadcast content provider that provides digital television broadcast signals.

11. The mobile phone of claim 8, wherein the transceiver additionally receives EPG (Electronic Program Guide) data via the mobile telecommunications network, the EPG data allowing for broadcast schedule searching using keywords, program titles, actor names and other program related concepts.

12. The mobile phone of claim 11, further comprising:

an output unit that cooperates with the data processor/converter to display the digital video and provide the audio data to the user, and also output the received EPG data to allow user selection thereof.

13. The mobile phone of claim 8, wherein the radio frequency transceiver, the digital signal processor, the storage, the data processor/converter, and the transcoder/transmitter further cooperate to perform at least one of subscriber billing, subscriber password and access rights management, and subscriber certification via the mobile telecommunications network.

14. The mobile phone of claim 8, wherein the data processor/converter performs the protocol conversion of signals or data complying with at least one of a ATSC standard, a DVB standard, a 3GPP standard, an OFDM standard, an MPEG-2 standard, an MPEG-4 standard, an H.26L standard, an H.263 standard, an H.26X standard, a WAP (Wireless Application Protocol) standard, a PSIP (Program Stream Internet Protocol) standard, a HDML (Handheld Device Mark-up Language) format, a TTML (Tagged Text Mark-up Language) format, HDTP (Handheld Device Transport Protocol) format, an ITTP (Intelligent Terminal Transfer Protocol) format, MHEG/XHTML (Multimedia and Hypermedia Expert Group/XHyper-Text Mark-up Language) format.

15. The mobile phone of claim 8, wherein the information stored in the storage includes additional data related to at least one of program system information (PSI), service guide information, subscriber billing, subscriber password and access rights management, and subscriber certification.

16. The mobile phone of claim 8, wherein the storage supports data storage techniques based upon at least one of a striping method and time-based data burst procedures using I-Frame value processing, Bit Rate Drop processing, and Macro Block and Intra/Inter compensation processing.
