Abstract

A device providing an automatic channel changing function includes: a receiving unit, receiving recommended program data, first user data and second user data from a first AV playing device; a storage unit, storing reference data; a look-up unit, generating channel changing data according to the recommended program data, the first user data, the second user data and the reference data; and a transmitting unit, transmitting the channel changing data to a second AV playing device according to the second user data.

Claims (25)

1. An automatic channel changing auxiliary device, comprising:

a receiving unit, receiving recommended program data, first user data and second user data from a first AV playing device when requested by the first AV playing device, wherein the recommended program data is of a program the first AV playing device suggests to a second AV playing device;

a storage unit, storing reference data;

a look-up unit, generating channel changing data according to the recommended program data, the first user data, the second user data and the reference data, wherein the first user data and the second user data correspond respectively to different users, and the channel changing data is of a program a first user suggests to a second user; and

a transmitting unit, transmitting the channel changing data to the second AV playing device according to the second user data.

2. The automatic channel changing auxiliary device according to claim 1 , wherein the reference data comprises a plurality of program lists, and the look-up unit is configured to:

identify a first program list from the program lists according to the first user data;

identify a second program list from the program lists according to the second user data;

identify a program name according to the recommended program data and the first program list; and

generate the channel changing data according to the program name and the second program list.

3. The automatic channel changing auxiliary device according to claim 2 , wherein the first user data comprises at least one of a user identity code, an electronic list identity code, television system category data, location data and content service provider (CSP) information.

4. The automatic channel changing auxiliary device according to claim 2 , wherein the recommended program data comprises a channel identity code and a timestamp.

5. The automatic channel changing auxiliary device according to claim 2 , wherein the recommended program data comprises a program identity code.

6. The automatic channel changing auxiliary device according to claim 2 , wherein the channel changing data comprises a channel identity code and a timestamp.

7. The automatic channel changing auxiliary device according to claim 2 , wherein the channel changing data comprises a program identity code.

8. An automatic channel changing method, applied to an automatic channel changing auxiliary device comprising a receiving unit, a look-up unit, a storage unit and a transmitting unit, the storage unit storing reference data; the automatic channel changing method comprising:

receiving, by the receiving unit, recommended program data, first user data and second user data from a first AV playing device when requested by the first AV playing device, wherein the recommended program data is of a program the first AV playing device suggests to a second AV playing device;

generating channel changing data according to the recommended program data, the first user data, the second user data and the reference data by the look-up unit, wherein the first user data and the second user data correspond respectively to different users, and the channel changing data is of a program a first user suggests to a second user; and

transmitting the channel changing data to the second AV playing device according to the second user data by the transmitting unit.

9. The automatic channel changing method according to claim 8 , wherein the reference data comprises a plurality of program lists; the step of generating the channel changing data according to the recommended program data, the first user data, the second user data and the reference data by the look-up unit comprises:

identifying a first program list from the program lists according to the first user data;

identifying a second program list from the program lists according to the second user data;

identifying a program name according to the recommended program data and the first program list; and

generating the channel changing data according to the program name and the second program list.

10. The automatic channel changing method according to claim 8 , wherein the first user data comprises at least one of a user identity code, an electronic list identity code, television system category data, location data and content service provider (CSP) information.
