Devices and methods for obtaining media stream with adaptive resolutions
Devices and methods for obtaining media stream with adaptive resolutions. The device includes a receiver in communication with a processor, and a transmitter. The receiver is configured to receive a plurality of media signals. The processor is programmed to communicate with a terminal device in the home network, obtain a corresponding display resolution of the terminal device, and select a media signal according to the corresponding display resolution of the terminal device and a video resolution of the media signal. The transmitter is configured to transmit media stream corresponding to the selected media signal to the terminal device.
1. A device in a home network, comprising:
a receiver configured to receive a plurality of media signals of various video resolutions from one or more media sources;
a processor programmed to communicate with a terminal device in the home network, obtain a profile associated with the terminal device containing a corresponding preset native display resolution of the terminal device, and select from the received plurality of media signals a media signal having a video resolution matching the preset native display resolution of the terminal device; and
a transmitter configured to transmit a media stream corresponding to the selected media signal to the terminal device.
2. The device of claim 1 , wherein the receiver receives the plurality of media signals from a broadcasting source.
3. The device of claim 1 , further comprising:
a non-transitory storage that stores information related to the corresponding preset native display resolution of the terminal device.
4. The device of claim 1 , wherein the plurality of media signals comprises linear TV programs.
5. The device of claim 4 , wherein the linear TV programs comprises at least one of: live sports, live news, and live events from a cable TV source, a satellite TV source, or an Internet Protocol television (IPTV) source.
6. The device of claim 1 , wherein the receiver comprises a television tuner configured to receive the plurality of media signals from a radio frequency signal source.
7. A method, comprising:
receiving, by a device having a processor, a request for media stream from a terminal device over a network;
obtaining, by the device, a profile associated with the terminal device containing a preset native display resolution of the terminal device based on the request;
selecting, by the device, from a plurality of media signals received from one or more media sources having various video resolutions, a media signal having a video resolution matching the preset native display resolution of the terminal device contained in the obtained terminal profile as a requested media stream; and
sending, by the device, the requested media stream to the terminal device.
8. The method of claim 7 , further comprising:
receiving, by the device, the plurality of media signals having various video resolutions from a broadcasting source.
9. The method of claim 7 , wherein obtaining the terminal profile based on the request comprises at least one of the following:
obtaining, by the device, the terminal profile locally in a storage of the device;
obtaining, by the device, the terminal profile from a pre-stored profile in the terminal device; and
obtaining, by the device, the terminal profile from a user.
10. The method of claim 7 , further comprising:
storing, in a non-transitory storage of the device, the terminal profile when the non-transitory storage does not already comprise the terminal profile.
11. The method of claim 7 , wherein the plurality of media signals comprises linear TV programs from a TV broadcaster, and wherein the linear TV programs comprises at least one of: live sports, live news, and live events.
12. A non-transitory storage medium configured to store a set of instructions, the set of instructions to direct a device to perform acts of:
receiving a request for media stream from a terminal device over a network;
obtaining a profile associated with the terminal device containing a preset native display resolution of the terminal device based on the request;
selecting from a plurality of media signals received from one or more media sources having various video resolutions, a media signal having a video resolution matching the preset native display resolution of the terminal device contained in the obtained terminal profile as a requested media stream; and
sending the requested media stream to the terminal device.
13. The non-transitory storage medium of claim 12 , wherein the set of instructions to direct the device to perform acts of:
receiving the plurality of media signals that having various video resolutions from a broadcasting source.
14. The non-transitory storage medium of claim 12 , wherein the set of instructions, when to direct the device to perform the act of obtaining the terminal profile, direct the device to perform act of:
obtaining the terminal profile locally in a storage of the device;
obtaining the terminal profile from a pre-stored profile in the terminal device; or
obtaining the terminal profile from a user.
15. The non-transitory storage medium of claim 12 , wherein the plurality of media signals comprises linear TV programs from a TV broadcaster, and wherein the linear TV programs comprises at least one of: live sports, live news, and live events.
16. The non-transitory storage medium of claim 12 , further configured to store the obtained terminal profile.
17. The device of claim 1 , wherein the plurality of media signals of various video resolutions are each from a different media source.
18. The device of claim 7 , wherein the plurality of media signals having various video resolutions are each from a different media source.
19. The device of claim 12 , wherein the plurality of media signals having various video resolutions are each from a different media source.
