Abstract

In a system for viewing accumulated contents by using a cellular phone, if an error prevents the content to be viewed, a simple operation is performed to view the rest at home. In accordance with a viewing request from a cellular phone, a television receiver, while sequentially receiving data from D-VHS, converts the data into a format suitable for reception and play in a cellular phone by using an encoder. After this format conversion, the television receiver stores in a play position memory a time stamp indicating a position information of a content and a sequence number used for transmission in TCP/IP. The cellular phone notifies the television receiver of a decode error of a reception data. When receiving a confirmation response of a normal play from the cellular phone, the television receiver clears the data of the play position memory, and otherwise holds the data of the play position memory.

Claims

1. A network information communication system, comprising:

a television receiver; and

an information terminal apparatus which are connected through a network,

the system communicating an image data therebetween,

wherein the information terminal apparatus includes;

communicating means for receiving the image data from the television receiver; and

display means for displaying the image data,

wherein the television receiver includes;

communicating means for transmitting the image data to the information terminal apparatus; and

storage means for storing a play position information of the image data in accordance with at least one of an operation state and a communication state of the information terminal apparatus.

3. A network information communication system according to claim 1, wherein the television receiver deletes the play position information from the storage means, in at least one of a case in which a reception confirmation response of the image data is received from the information terminal apparatus and a case in which no decode error of the image data occurs.

4. A network information communication system according to claim 1, wherein the television receiver has display means for displaying an image in which a start position of play is controlled in accordance with the play position information.

2. A television receiver connectable through a network to an information terminal apparatus, comprising:

communicating means for transmitting an image data to the information terminal apparatus;

storage means for storing a play position information of the image data in accordance with at least one of an operation state and a communication state of the information terminal apparatus; and

controlling means for allowing an image, for which a play position is controlled in accordance with the play position information, to be displayed.

5. A television receiver according to claim 2, wherein the play position information includes:

a time information to specify a start position of play; and

a still image data corresponding to the time information.

6. A television receiver according to claim 5, wherein a still image is index-displayed in accordance with the still image data.

7. A television receiver according to claim 5, further comprising means for generating and storing a digest stream of an image data in accordance with the play position information,

wherein the digest stream corresponding to the selected still image is obtained from the storage means and displayed by the display means.

8. A control method for a network information communication system, which communicates a content between a television receiver and an information terminal apparatus that are connected through a network, comprising:

a step of requesting, with the information terminal apparatus, a content from the television receiver;

a step of transmitting, with the television receiver, the content to the information terminal apparatus;

a step of storing, with the television receiver, a play position information of the content in play position storage means; and

a step of clearing, with the television receiver, when receiving a reception confirmation response of the content from the information terminal apparatus, the play position information.

9. An information communication system, comprising:

an information controller; and

an information terminal apparatus;

the system distributing a data from the information controller to the information terminal apparatus, through a network,

wherein the information controller includes;

communicating means for transmitting the data to the information terminal apparatus and receiving an information transmitted from the information terminal apparatus; and

storage means for storing a play position information of the data in accordance with the information,

wherein the information terminal apparatus includes;

communicating means for receiving the data transmitted from the information controller and transmitting the information corresponding to the data to the information controller; and

playing means for playing the data received by the communicating means.

10. An information controller, which can transmit a data to an information terminal apparatus through a network, comprising:

communicating means for transmitting the data to the information terminal apparatus and receiving an information corresponding to the data transmitted from the information terminal apparatus; and

storage means for storing a play position information of the data in accordance with the information.

11. An information communication method for an information controller for transmitting a data to an information terminal apparatus through a network, including:

a communication control step of transmitting the data to the information terminal apparatus and controlling reception of an information corresponding to the data transmitted from the information terminal apparatus; and

a memory control step of controlling a memory of a play position information of the data in accordance with the information.

12. A program readable by a computer, which causes the computer to execute the information communication method according to claim 11.
