Video on demand processing

摘要

A device may include a communication interface configured to receive a request from a client device, where the request identifies a first video on demand (VOD). The device may also include logic configured to identify capabilities associated with the client device, the capabilities including at least one of a decoding capability of the client device, a content protection scheme supported by the client device, or a transport protocol via which the client device can communicate, and forward the request for the VOD to a service provider associated with providing the first VOD. The logic may also be configured to receive a media stream from the service provider, the media stream corresponding to the first VOD, process the media stream in accordance with the identified capabilities, and forward the processed media stream to the client device.

1. A device, comprising:
a communication interface configured to receive a request from a client device, the request identifying a first one of a plurality of videos on demand; and logic configured to:
identify capabilities associated with the client device, the capabilities including a content protection scheme supported by the client device and at least one of a decoding capability of the client device or a transport protocol via which the client device can communicate,allocate a predetermined amount of bandwidth for each of a plurality of different classes of traffic in a customer premises in which the client device is located, wherein a first one of the classes of traffic comprises video on demand (VOD) traffic,forward the request for the first VOD to a service provider associated with providing the first VOD,receive a media stream from the service provider, the media stream corresponding to the first VOD,identify a VOD download bandwidth limit for the customer premises based on the predetermined amount of bandwidth allocated to VOD traffic,process the media stream in accordance with the identified capabilities and in accordance with the VOD download bandwidth limit, andforward the processed media stream to the client device, wherein when processing the media stream in accordance with the VOD download bandwidth limit, the logic is configured to:
determine whether providing the media stream to the client device at a first resolution will place the customer premises over the VOD download bandwidth limit, andtranscode the media stream at a second resolution, lower than the first resolution, in response to determining that providing the media stream to the client device at the first resolution will place the customer premises over the VOD download bandwidth limit.
